SWITZERLAND

(Updated 2013)

1. GENERAL INFORMATION

1.1. Country overview

Switzerland is one of the most mountainous countries in Europe, with more than 70 % of its area covered by the Alps and the Jura. It has 7,954,662 (2011 data) inhabitants, with an overall population density of about 193 people per km2. The major language communities are: German, French, Italian, and Romansh. Foreign nationals and their families make up roughly 23 % of the population.

1.1.1. Governmental System

Switzerland is a federal state with three political and legal levels: the communes (2408, 2013 data), the cantons (26) and the Confederation. The Swiss parliament, or Federal Assembly, is made up of two chambers: the National Council and the Council of States. Every four years, the people elect the 200 members of the National Council, as for the last time in October 2011. The government is made up of seven members, elected by the United Federal Assembly.

1.1.2. Geography and Climate

Switzerland covers an area of 41,285 km2, comprising 31% forest and grove, 37% cropland and pastureland, 7% built-up and 25% un-productive land (situation in the mid-1990s). Around 4% of the country’s surface area is covered by water. Climatic conditions, average temperature and precipitation patterns vary significantly across Switzerland, depending mainly on altitude and location.

1.2.3. Energy policy

After the Fukushima accident in 2011, the Federal Council decided to phase out nuclear power: The five existing NPPs are to continue operating until the end of their lifetime (the first NPPs are likely to be shut down around 2020, the last one by 2034). Permitting for three new NPPs was halted. The phase-out decision stemmed from the fact that public opinion – split 50/50 before Fukushima – had become overwhelmingly anti-nuclear. Approval of new NPPs in foreseeable referendums had therefore become impossible. The phase-out decision has also been endorsed by Swiss Parliament (National Council and Council of States).

The nuclear phase-out requires a new Energy Policy to be formulated to replace some 40% of current electricity supply coming from nuclear power (assuming electricity demand growth can be eventually stabilized in the years to come). The gap is to be filled by a mix of options, including ambitious efficiency measures, accelerated promotion of new renewable energies and additional large hydro, and some likely gas-fired GTCC and combined heat-and-power plants, as well as increased electricity trade. Gas-fired power, a novelty for Switzerland, will be challenging for the national climate policy goal.

The public consultation on the new energy policy, the so-called “Energy Strategy 2050” took place from 28 September 2012 to 31 January 2013. The Swiss Federal Office of Energy (SFOE) is evaluating the statements and will adjust the project accordingly. The Federal Council is expected to present its message to the Parliament in September 2013.

1.3. The electricity system

1.3.1. Electricity policy and decision making process

The Federal Electricity Supply Act (StromVG, effective since 1 January 2008) creates the framework for a phased liberalisation of the Swiss electricity market. The market was partially opened for eligible customers(1) in 2008. Full market liberalisation will be introduced on the basis of a federal resolution, which will be subject to an optional referendum.

In order to increase the share of electricity produced from renewable energy sources, an amendment was made to the Electricity Supply Act introducing compensatory feed-in remuneration to cover the cost of electricity from renewable energy sources.

1.3.2. Structure of electric power sector

Roughly 40% of Swiss electricity generation comes from nuclear power, with the remaining share mostly produced by large hydropower plants (see following section). Switzerland’s electricity market is highly fragmented. The supply of electricity is assured by some 750 companies, including 7 generation and transmission companies and approximately 80 producers. Many tasks are undertaken by the communes, which also supply water and gas. In some cantons and cities, a single vertically-integrated company is responsible for the entire supply chain, while in other cantons these are provided by a variety of companies. The public sector stake in the capital stock of electricity supply companies is currently around 80%, while the remaining 20% is held by private-sector companies (domestically and abroad).

Switzerland regulated grid usage in the above-mentioned Electricity Supply Act. It stipulates that the high-voltage transmission grid should be operated by the national grid company, Swissgrid, which guarantees non-discriminatory access to the grid for all companies. In accordance with the Federal Electricity Supply Act, the ownership of ultra-high-voltage network was transferred to Swissgrid by 1 January 2013. The Act also stipulates the unbundling of previously vertically integrated companies.(2)

ElCom is Switzerland’s independent regulatory authority in the electricity sector. It is responsible for monitoring compliance with the Swiss Federal Electricity Act taking all necessary related decisions and pronouncing rulings where required. ElCom monitors electricity prices and rules as a judicial authority on disputes relating to network access and payment of cost-covering feed-in of electricity produced from renewable energy. It also monitors electricity security of supply and regulates issues related to international electricity transmission and trading.

1.3.3. Main indicators

In 2011, hydropower's share of total electricity production was 54%, nuclear power contributed 41%. The remaining 5% is covered by fossil and renewable sources. Table 5 and 6 on the following page provide further information on the electricity production, consumption and capacity.

2. NUCLEAR POWER SITUATION

2.1. Historical development and current organisational structure

2.1.1. Overview

Development of a nuclear programme

In November 1945, the Swiss government established the independent Atomic Energy Committee with the mandate to advise the government in all civilian and military matters dealing with nuclear energy. In 1946, the Swiss government mandated the Atomic Energy Committee to investigate all aspects dealing with nuclear weapons, i.e. to prepare the necessary measures for protecting army and population against their impact and also to study what would be required to develop such weapons. On 18 March 1957, parliament ratified the IAEA Statute which entered into force on 29 July 1957. In 1969, Switzerland signed the Non-Proliferation Treaty which was ratified by parliament on 9 March 1977.

As early as 1946, Brown, Boveri & Cie. (BBC), now ABB Group, took the first steps to build up a team of physicists and to launch a development programme. BBC was later joined by Sulzer Brothers and Escher-Wyss. Initial studies dealt with graphite-carbon dioxide reactor concepts, but from 1952 on, the development concentrated on heavy water moderated reactors with the subsequent planning of the research reactor DIORIT. In 1955, more than 150 private companies joined forces and formed the company “Reactor Ltd” to build and operate the new privately-owned research centre in Würenlingen, with two reactors on the site: SAPHIR and DIORIT. In 1960, the federal government took over the research centre, known under its abbreviation EIR (Eidgenössisches Institut für Reaktorforschung). In 1988, the merger of EIR and SIN (Schweizerisches Institut für Nuklearphysik) led to the creation of the Paul Scherrer Institute (PSI).

In Switzerland, the nuclear age began on 30 April 1957, when the SAPHIR research reactor went critical under the responsibility of Swiss scientists and engineers. This pool reactor had been purchased in 1955 from the US Government, after being exhibited in Geneva during the First International Conference on the Peaceful Uses of Atomic Energy. SAPHIR was shut down permanently at the end of 1993.

DIORIT, the first reactor designed and constructed in Switzerland, reached criticality on 15 August 1960. It was moderated and cooled by heavy water; the fuel was initially natural uranium; a special loop allowed for the testing of power reactor fuel elements. DIORIT was shut down permanently in 1977. At the end of 2003 all radioactive material was removed from the reactor building.

In 1962, the construction of the experimental nuclear power reactor in Lucens, a 30 MWth, 6 MWe, heavy-water moderated, carbon dioxide cooled reactor located in an underground cavern started. Criticality was reached in late 1966 and commissioning in early 1968. In spite of numerous difficulties, the supply consortium led by Sulzer Brothers had demonstrated that Swiss industry was capable of building nuclear plants. The goal was the development of a small to medium-sized power reactor fuelled with natural uranium within a massive containment system. As enriched uranium became readily available during the mid-1960s, the unit size of commercially offered light water reactor (LWR) nuclear power plants (NPPs) increased drastically and Swiss utilities started construction of such plants very early on; the interest in the Lucens reactor type decreased and further large expenses for such a development could not be justified. The decision was taken to operate the reactor until the end of 1969. However, on 21 January 1969, the plant was abruptly put out of service by a partial core meltdown that destroyed the integrity of the primary system and released radioactivity into the cavern. After decontamination, decommissioning and termination of intermediate storage of radioactive material, the whole site was prepared for unrestricted reuse in 2003.

Nuclear power plant projects

In August 1965, a turnkey contract was awarded by Nordostschweizerische Kraftwerke AG (NOK) to a consortium made up of Westinghouse International Atomic Power Co, Ltd. and Brown, Boveri & Cie. for the supply of a 350 MWe plant equipped with a pressurised water reactor and two turbo-generators (Beznau). In late 1967, NOK took the option to order a duplicate of the first unit. Beznau I reached criticality by the end of June 1969, and Beznau II in October 1972.

Also in 1965, Bernische Kraftwerke AG (BKW) chose a 306 MWe plant equipped with a boiling water reactor (BWR) manufactured by General Electric (GE) and twin turbo-generators from BBC (Mühleberg). In July 1971, full power was achieved, but on 28 July 1971 a turbine fire broke out. Sixteen months later the plant was officially handed to the owner.

In 1973, a supply contract was signed by a consortium of Swiss utilities with Kraftwerk Union (Siemens) for the delivery of a 900 MWe PWR and turbo-generator (Gösgen). Construction of the plant went very smoothly until the first connection to the grid in February and 80% power test in March 1979. However, the accident at Three Mile Island on 29 March 1979 led to an 8 month delay in commissioning.

In December 1973, a consortium of Swiss utilities and one German utility awarded a turnkey contract to General Electric Technical Services Overseas (GETSCO) and BBC for the supply of a 940 MWe NPP plant equipped with a BWR (Leibstadt). Construction began in 1974 and the plant was commissioned in December 1984.

Political controversy and legal framework

The nuclear controversy began in Switzerland in 1969 with the first signs of local opposition to a nuclear plant project at Kaiseraugst, near Basel. For 20 years, the Kaiseraugst project was to remain centre stage in the nuclear controversy: Site permit, local referenda, legal battles, site occupation by opponents in 1975, parliamentary vote in favour of construction in 1985, and finally parliamentary decision in 1989 to end the project definitively. The Chernobyl accident had a dramatic impact on the political climate. Although some of the necessary permits had already been issued for two planned NPPs at Kaiseraugst and Graben, their construction was subsequently abandoned, as well as other projects in Verbois, Inwil and Rüthi.

The nuclear controversy led to several anti-nuclear initiatives at the federal level:

  1. an attempt to forbid all nuclear plants, both new and those already in operation – rejected by 51.2% of the vote in February 1979;

  2. aimed at forbidding future nuclear plants, leaving untouched the plants in operation, two initiatives differing only in the treatment to be applied to Leibstadt, then under construction – rejected by 55% of the vote in September 1984;

  3. nuclear phase-out – rejected by 52.9% of the vote in September 1990;

  4. 10-year moratorium on the construction of new NPPs – accepted by 54.6% of the vote in September 1990;

  5. in 1999, two new initiatives were organised aiming at the ban of the construction of new NPPs until 2010 and the closure of all NPPs after a 30 year lifespan – both initiatives were rejected in May 2003 by 58.4% and 66.3% respectively.

A new Nuclear Energy Act came into force on 1 February 2005. It allowed the possibility of building new reactors, with the possibility of a referendum against their construction; no time limit is imposed on the life of existing NPP; the general license is maintained. It introduces a 10-year-moratorium on the export of nuclear fuel for reprocessing from 2006 to 2016. It also includes provisions for decommissioning, it simplifies licensing procedures and introduces the general right of appeal. A new Nuclear Energy Ordinance came into force together with the Act.

During the 10-year moratorium regarding reprocessing, which began in July 2006, spent fuel is stored in Switzerland. Plutonium and uranium gained from reprocessing of spent fuel that was sent abroad before July 2006 is recycled in Swiss NPPs. The radioactive waste arising from reprocessing of spent fuel is returned to Switzerland.

Following the reactor accident in Fukushima, the head of the Federal Department of the Environment, Transport, Energy and Communications (DETEC) announced in mid-March 2011 that the pending procedures for handling applications for general licenses for new NPPs had been suspended. Then, in the course of 2011, with their decision to withdraw from the use of nuclear energy on a step-by-step basis the Federal Council and Parliament laid the foundations for a new energy policy, the Energy Strategy 2050. The intention is to decommission Switzerland's five NPPs when they reach the end of their service life and not to replace them with new ones. According to the Energy Strategy 2050, reprocessing would be forbidden.

The public consultation on the Energy Strategy 2050 took place from 28th September 2012 to 31st January 2013. The Federal Council is expected to present its message to the Parliament in September 2013.

Radioactive waste management

The safe disposal of radioactive waste is the responsibility of those parties who produce it, namely the following NPP operators: BKW FMB Energie AG (Mühleberg), KKW Gösgen-Däniken AG, KKW Leibstadt AG, Nordostschweizerische Kraftwerke Baden – now Axpo (Beznau I and II), Energie Ouest Suisse – now Alpiq. In 1972, the above operators established the National Co-operative for the Disposal of Radioactive Waste (Nagra) together with the federal government which is responsible for the disposal of radioactive waste from the healthcare sector, industry and research and is represented by the Federal Department of Home Affairs.

So far, there are no deep geological repositories in Switzerland. For both Low/Intermediate Level Waste (L/ILW) and High Level Waste (HLW) repositories, a site selection process is defined in a sectoral plan within the framework of the spatial planning legislation. The Federal Council adopted the conceptual part of the “Sectoral Plan for Deep Geological Repositories” in April 2008, thus initiating a three-stage procedure that will result in the designation of suitable sites for deep geological repositories.

The selection – based on safety criteria – of siting regions for geological repositories for HLW and for L/ILW was the goal of the first stage. Nagra proposed six potential siting regions in October 2008. The Swiss Federal Nuclear Safety Inspectorate (ENSI), considering the input of a number of expert organisations, approved the six proposals. Following this review process, the Swiss Federal Office of Energy (SFOE) carried out a broad consultation on the first stage at the end of 2010 and submitted a report to the Federal Council. The Federal Council approved all six potential siting regions on 30 November 2011, thus concluding the first stage of the site selection process and initiating the second stage (see section 2.7).

2.2.1. Status and performance of nuclear power plants

Five NPPs at four sites are currently in operation in Switzerland (see Table 7). There are four research reactors and two central disposal facilities for radioactive waste. Disposal facilities for radioactive waste are situated in the surroundings of the NPPs too. Switzerland’s five NPPs have a total capacity of 3.3 GW, and an annual availability rate of approximately 90%. Figure 2 on page 19 indicates the sites of the Swiss research reactors and NPPs.

2.2.2. Plant upgrading, plant life management and license renewals

In the course of time, all Swiss NPPs have upgraded their power capacity. At the end of 2012, the nominal net powers were twice 365 MWe for Beznau-, 373 MWe for Mühleberg-, 985 MWe for Gösgen- and 1120 MWe for Leibstadt-NPP.

The power plants of Beznau (Units 1 & 2), Gösgen and Leibstadt have unlimited operating licenses. In December 2009, the DETEC granted an unlimited operating license for the operator of Mühleberg. This decision has been appealed and subsequently approved by the Federal Supreme Court in March 2013. As a result, the operator of Mühleberg NPP and hence all Swiss NPPs have unlimited operating licenses.

2.3. Future development of Nuclear Power

2.3.1. Nuclear power development strategy

The Swiss government announced a new energy policy in 2007 which included renewable energies, energy efficiency, energy foreign policy and new large-scale power stations, including the replacement of the existing NPPs. In 2008, the three big electricity companies Alpiq, Axpo and BKW submitted general license applications for three new nuclear units at Goesgen, Beznau and Muehleberg, all three on existing nuclear sites (see section 2.3.5 for more information on these applications).

Following the nuclear accident at the Fukushima NPP in Japan, the head of the DETEC suspended the licensing procedure for the new Swiss NPPs. The decision was taken only three days after the nuclear accident in Japan, on 14 March 2011.

As a consequence of the events in Japan, the ENSI immediately started carrying out a safety review of the existing NPPs. According to an ENSI ordinance, the Swiss NPPs had to participate in the EU-Stress tests. The European Nuclear Safety Regulators Group (ENSREG) in charge of this peer review process stated in the final report for Switzerland: “In general, the design and further development of the plants are based on the ‘defence in depth’ concept and in consequence results in good robustness of the plants against severe accidents”. ENSREG recommends “that the regulator assesses the opportunity of requiring more reliance on passive systems for hydrogen management for severe accident conditions. It is also recommended that the regulator considers further studies on the hydrogen management for the venting systems”. Based on the reviews carried out so far, several measures have been taken to optimize safety and security. They are included in the post-Fukushima action plan. This plan foresees that 45 open points will be dealt with until 2015.

On 25 May 2011, the Federal Council decided to phase out nuclear power. The Swiss parliament (National Council and Council of States) subsequently confirmed the Federal Council’s decision by approving a stepwise phase out of nuclear power: Existing NPPs should be decommissioned at the end of their operational lifespan and not be replaced by new NPPs, as originally foreseen. The new Energy Strategy 2050 is expected to be submitted to parliament for debate in September 2013.

The owners and operators of NPPs are responsible for fuel cycle planning and decision-making. They make contracts in accordance with national legislation and international agreements. The strategy chosen by the NPP operators includes the reprocessing and storage of spent fuel, the latter with a view to later reprocessing or direct disposal. The reprocessing takes place abroad (France and UK). Plutonium and uranium gained from reprocessing is used for fuel fabrication and is reused in Swiss NPPs. The radioactive waste arising from reprocessing is returned to Switzerland. However, according to article 106 paragraph 4 of the Nuclear Energy Act (NEA, SR 732.1), spent fuel elements may not be exported for reprocessing for a period of ten years with effect from 1 July 2006. During this period they shall be managed as radioactive waste. According to the above-mentioned Energy Strategy 2050, reprocessing would be forbidden.

In accordance with the polluter-pays principle, producers of radioactive waste in Switzerland are responsible for ensuring its safe disposal at their own cost. The various ongoing costs (e.g. studies carried out by Nagra, construction of interim storage sites, site selection procedure for deep geological repositories) have to be paid as they arise. Decommissioning costs and expenditure associated with the management (including disposal) of radioactive waste after a NPP has been closed down, are secured through contributions paid into two independent funds by the operator:

  • Decommissioning fund

  • Waste Disposal fund

The Nuclear Energy Act and the Ordinance on the Decommissioning Fund and the Waste Disposal Fund (7 December 2007) form the legal basis for these two funds.

2.3.2. Project management

Licensing procedures are divided in three stages: i) the general license procedure, ii) the construction license procedure and iii) the operating license procedure.

The Federal Council is responsible for decision making regarding the application for general license. The decision of the Federal Council will be brought before parliament. It is then subject to an optional national referendum. The Swiss government consists of the seven members of the Federal Council who are elected by the United Federal Assembly for a four-year term.

The DETEC is responsible for the decision making regarding the application for construction and operating licenses. Its decisions can be appealed to the Federal Administrative Court, and at a later stage to the Federal Supreme Court. About 1900 people work within DETEC (including its agencies like SFOE).

The SFOE has the lead on all three authorisation procedures. The SFOE employs almost 200 staff members. As of the beginning of March 2013, the SFOE comprises six divisions and two operational sections.

The ENSI is the national regulatory body with responsibility for the nuclear safety and security of Swiss nuclear facilities. In the licensing procedures it is also responsible for safety-related examination and assessment of the facilities. Most of ENSI’s expenses are covered by fees which license holders have to pay to the federal government. ENSI currently employs around 150 staff members: physicists, mechanical, electrical and civil engineers, geologists, chemists, biologists and psychologists, in addition to technical and administrative personnel.

Other public entities involved in the above mentioned authorisation procedures are the Swiss Federal Nuclear Safety Commission NSC, the Federal Office for the Environment FOEN, the Federal Office for Spatial Development ARE and the cantons.

2.3.3. Project funding

No government financial support is granted for the construction of new NPPs. Some public entities such as the cantons nevertheless have considerable shares of some of the relevant companies.

2.3.4. Electric grid development

The transmission and distribution networks need to be modernized and expanded. To cope with the increasing fluctuations in electricity production (like wind and photovoltaic) electricity systems have to become more flexible. The continuous balance between production and consumption needs to be guaranteed under increasingly dynamic conditions and grids need to become more automated. Smart grids offer one possible solution to these challenges.

Switzerland is closely integrated into the European electricity system. A close integration is of mutual benefit for Switzerland and its neighbouring countries with respect to security of supply. A national strategy for energy networks including aspects of the international integration will be defined to this end. This strategy will also include measures to accelerate the approval process and address aspects concerning the costs of grid expansion and renovation as well as the development of electricity grids towards smart grids.

2.3.5. Site Selection

On 9 June 2008, Kernkraftwerk Niederamt AG, a subsidiary of Atel Holding AG (now known as Alpiq Holding AG), submitted an application to the SFOE for a general license for a NPP with a maximum output of 1,600 MW. The plan for the new facility was to be constructed in Niederamt (canton of Solothurn), near the existing Gösgen NPP.

On 4 December 2008, on behalf of Axpo Holding AG and BKW FMB Energie AG respectively, Ersatz Kernkraftwerk Beznau AG and Ersatz Kernkraftwerk Mühleberg AG each submitted an application to the SFOE for a general license for the construction of new NPPs to replace the existing Beznau I, Beznau II and Mühleberg facilities. The plan was for these new NPPs, each with a maximum output of 1,600 MW, to be constructed at the locations of the existing facilities, namely in Beznau (canton of Aargau) and Mühleberg (canton of Bern).

All three applications have been examined in detail by the ENSI. It attested on 15 November 2010 that the data provided by the applicants are scientifically correct. The reviewed applications satisfy the legal requirements. The Nuclear Safety Commission NSC released its opinion on 10 January 2011. It states that ENSI delivered an in-depth safety review. The NSC has also made a number of recommendations.

All three procedures were suspended on March 2011 as a consequence of the nuclear accident in Japan.

2.4. Organisations involved in construction of NPPs

Not available.

2.5. Organisations involved in operation of NPPs

The following organisations operate a NPP:

  • KKG AG

  • KKL AG

  • Axpo AG

  • BKW FMB Energie AG

Major Switzerland based vendors / supporting organisations are:

  • ABB AG

  • Alstom AG

  • AF-Colenco AG

  • CCI Schweiz AG

More information can be found at http://www.nuclearindustry.ch

2.6. Organisations involved in decommissioning of NPPs

No commercial NPP is under decommissioning.

2.7. Fuel cycle including waste management

Fuel supply

Switzerland has no domestic nuclear fuel-cycle industry. Enrichment is provided by the USA, Russia and countries of the European Union. The fuel elements are manufactured in the USA, countries of the European Union and Russia.

Legal framework

In 2003, the parliament decided to introduce a 10-year moratorium on the export of spent fuel for reprocessing, which started in July 2006. Before the start of the moratorium, the utilities were free to choose between reprocessing and direct disposal of the spent fuel. The Nuclear Energy Act states a series of conditions which must be fulfilled for an authorization of the export of spent fuel for reprocessing to be granted. The conditions include an agreement with the country of destination, the existence in that country of an adequate facility corresponding to the international standards and the fact that the country of destination has ratified the Convention on Nuclear Safety and the Joint Convention. An intention of the new Energy Strategy 2050 is to fully forbid reprocessing.

The management (handling and storage) of radioactive waste is governed by the provisions of the Nuclear Energy Act and the Nuclear Energy Ordinance, both of which entered into force on 1 February 2005. The management of radioactive waste originating from medicine, industry and research is governed by the Radiological Protection Act and the Radiological Protection Ordinance, both of which entered into force on 1 October 2004.

All radioactive waste is to undergo storage in repositories situated in suitable geological formations; near-surface disposal is not allowed. Since no repository is yet available, all radioactive waste is stored in interim storage facilities.

Storage facilities

At present, the following spent fuel and radioactive waste management facilities exist in Switzerland:

  • NPPs:

    All Swiss NPPs have on-site installations for the conditioning and storage of their own operational waste.

  • ZZL / Central Storage Facility:

    This facility operated by the company ZWILAG in Würenlingen is comprised of an interim storage facility for spent fuel and all kinds of radioactive waste, conditioning installations and a plasma furnace for melting and incineration of low level waste.

  • Separate storage facility ZWIBEZ at Beznau NPP:

    It consists of a hall for low level operational waste and a hall for the dry storage of spent fuel.

  • Wet storage facility at Gösgen NPP:

    This facility storage is an additional spent fuel pond on the site of the Gösgen NPP. It is intended for independent operation over several years after the future shutdown of the Gösgen NPP.

  • National Collection Centre and Federal Storage Facility:

    These installations for radioactive waste from medicine, industry and research are operated by the Paul Scherrer Institute (PSI) in Würenlingen.

Deep geological repositories and site selection process

The responsibility for radioactive waste management lies with the waste producers. Legislation requires that radioactive waste produced in Switzerland be disposed of in Switzerland. The option for the disposal of radioactive waste within the framework of a bilateral or multilateral project is kept as an option, but is not actively pursued.

Two repositories are proposed, one for short-lived L/ILW and one for HLW and spent fuel as well as long-lived intermediate level waste mainly from reprocessing. The site selection process has to follow a sectoral plan procedure within the framework of spatial planning legislation. The site selection process according to the sectoral plan procedure for deep geological repositories was started with the promulgation of the “Sectoral Plan for Deep Geological Repositories” on 2 April 2008 by the Federal Council. It will last around fifteen years and lead to the decision of the Federal Council regarding the issuing of the general licenses for the repositories.

Site selection is based primarily on scientific and technical criteria, with the main emphasis on safety, but socio-economic and environmental aspects must also be addressed. The SFOE is in charge of the site selection procedure, which allows the coordination of a broad range of actors and is divided into three stages.

With regard to the first stage of the site selection process, the Nagra submitted its proposals for suitable geological siting areas for the repositories for HLW and L/ILW to the SFOE on 17 October 2008. ENSI reviewed Nagra’s entire documentation and, in conclusion, approved the six geological siting areas proposed for L/ILW: Jura Ost (canton Aargau), Jura-Südfuss (canton Solothurn and canton Aargau), Nördlich Lägern (canton Zurich and canton Aargau), Südranden (canton Schaffhausen), Wellenberg (canton Nidwalden and canton Obwalden) and Zürich Nordost (canton Zurich and canton Thurgau). All these sites have clay-rich sediments as potential host rocks. These include the Opalinus clay, the Brauner Dogger, the Effingen Beds, and the marl formations of the Helveticum.

ENSI also approved the three geological siting areas proposed for HLW: Jura Ost, North of Lägern and Zürich Nordost. All the potential HLW sites have Opalinus clay as host rock. ENSI’s review has been commented by the NSC.

A broad consultation was carried out in 2010 by the SFOE which compiled the comments and submitted a report to the Federal Government. The Federal Government approved all six potential siting regions (see Figure 1, page 19) on 30 November 2011, thus concluding the first stage of the site selection process and initiating the second stage.

The second stage of the process will define the location of the repository surface facilities in each of the siting regions and will narrow down the number of siting regions to at least two each for the L/ILW and the HLW repositories. It will address safety issues as well as spatial planning and socio-economic considerations and includes the participation of the siting regions through “regional conferences”. Stage 2 is expected to last about five years.

In stage 3, the remaining sites are studied in greater detail from the point of view of site selection and submission of a license application, and the site-specific geological information is intensified by carrying out further geological studies. With input from the siting region, the various storage site projects are defined in greater detail at this stage, and socioeconomic studies are intensified. The waste producers finally submit applications for a general license (one each for HLW and L/ILW or one for a combined repository). Parliament’s decision concerning the government’s approval of the general license for deep geological repositories is expected around 2023. That decision is subject to an optional national referendum.

After the construction and operation of an in situ rock laboratory will follow applications for a construction license and ultimately for an operating license for each repository, both of which will be granted by the relevant Federal Department. According to the current schedule, the L/ILW repository should be operational around 2035 and the HLW repository around 2050.

2.8. Research and development

2.8.1. R&D organisations

The Paul Scherrer Institute (PSI) is the largest research centre for natural and engineering sciences within Switzerland. Approximately 400 scientists (2012 data) at the Institute perform high-level research in a large variety of scientific questions that can be grouped into three main fields: Matter and Material, Human Health, and Energy and Environment. By conducting fundamental and applied research, PSI works on long-term solutions for major challenges facing society, industry and science.

PSI operates several large-scale facilities that allow experiments to be performed that would be impossible in smaller laboratories. The facilities are unique in Switzerland, and some of them are the only ones of their type or scale in the world. The Institute provides access to the facilities within the framework of a User Service to researchers from universities, other research centres and industrial companies. Each year, about 2,300 researchers in these categories perform experiments at the facilities.

Energy and Environment

The goal of PSI’s energy research is the development of technologies for a sustainable use of energy. This includes environmentally friendly energy production, the application of renewable energy sources, and low-loss energy storage. In addition, technologies are investigated which will contribute to the safe use of nuclear energy. Environmental research is concentrated on the study of processes taking place in the atmosphere.

Nuclear Energy Research

About 10% of the PSI’s annual government funding of CHF 240 million was earmarked for nuclear energy research (2009 data). The PSI’s government-funded nuclear energy research activities have been reduced by more than half over the past two decades. To a large extent, this reduction was compensated by external funding. With the current staffing quota per year of about 185 person-years (plus about 30 PhD students), and about CHF 7m to 8m for operations and maintenance and investment costs, a balance has been reached. More than 50% of the overall direct costs of nuclear energy research are externally funded by the Swiss NPP Operators, the Nagra, the ENSI and other national and in particular international agencies (inter alia EU and OECD/CSNI). Most of this support is for long-term research contracts.

About 50% of the nuclear energy research at PSI concentrates on reactor safety and safety-related operational aspects of Swiss NPPs and on nuclear waste disposal. With nearly 20% of the resources, future reactor concepts, in particular their safety features, which rely on inherent safety mechanisms and on passive system layouts are investigated (to a limited extent through an active partnership of PSI in the Generation IV International Forum (GIF)).

The main objectives of nuclear energy research carried out in the “Nuclear Energy and Safety” (NES) research department at the PSI are as follows:

  1. to contribute to the safe and economic operation of the existing NPPs in Switzerland and to the safe geological storage of radioactive waste by reinforcing the scientific bases of the technologies in the appropriate areas;

  2. to support the reactor operators and safety authority in Switzerland, as well as the securing of stand-by functionality in key areas, particularly those requiring the services of a Hot Lab;

  3. to prepare inputs to ‘stakeholders’ for decision-making purposes;

  4. research and development in nuclear energy in terms of increased sustainability, safety and economy;

  5. to train young nuclear specialists over a broad spectrum of disciplines, including those with experience of other energy systems;

The NES department is structured into five research laboratories according to its specific scientific and technical areas of competence. It operates the only Hot Lab in the country, and the Reactor School offers education and training programmes for present and future reactor operators.

The following provides a brief description of the programmes currently carried out within the NES department:

Operating reactors

The STARS programme is a long-standing project aimed at the development, maintenance and application of a complex code and database system to be used for investigations on the behaviour of the Swiss nuclear reactors. Focus areas include combined system transient and uncertainty analysis, fuel modelling and neutronics.

The main focus in the HRA (Risk and Human Reliability) is related to the solution of current and future issues concerning the handling of human factors in the context of Probabilistic Safety Assessment (PSA).

The Nuclear Fuels programme involves micro-structural/micro-mechanical examination of the ageing of core internals (fuel rods, structural materials), and the development of associated theoretical models. In particular, investigation of fuel damage and identification of possible causes of failure are also being carried out. Methods for the production of Gen IV fuels, and their associated fuel cycles, are also under consideration.

The Component Safety programme (INTEGER) involves the experimental characterisation of important ageing mechanisms (stress corrosion cracking, thermal fatigue and irradiation embrittlement) in primary pressure boundary components, the development and validation of advanced mechanistic material ageing models and probabilistic methods for improved integrity assessments and lifetime predictions, as well as the evaluation of advanced non-destructive techniques for the early detection of fatigue and stress corrosion crack initiation and for the characterisation of the actual degree of embrittlement in components.

The Source-Term Evaluation programme activities are centred on the ARTIST test facility, which reproduces, at reduced scale, aerosol deposition behaviour during a severe accident following a postulated steam generator tube rupture. General considerations of iodine chemistry are being investigated, with specific application to NPPs. The experimental programme is balanced by the development and validation of numerical models, the overall theme being aimed at replacing the existing empirical models by mechanistic modelling using CFD. All activities are directed towards source-term evaluation relevant to the Swiss NPPs.

Waste management

The programme is an ongoing commitment, overseen by the federal government, to ensure the safe disposal of radioactive waste from the medical and nuclear industries, but also including that arising from nuclear research. The activities cover fundamental waste-disposal chemistry, the physics and chemistry of radio nuclides, and investigation of the geological boundaries for radionuclide transport. Results will ultimately find use in the comprehensive application of safety criteria. This R&D programme is carried out in close co-operation with Nagra.

Energy systems analysis

These activities are carried out within the Laboratory for Energy System Analysis (LEA) which is an interdisciplinary laboratory supporting both NES and the General Energy Department (ENE). The Laboratory aims to contribute to effective decision-making on long-term technology strategies in energy supply and demand by ensuring the full integration of all environmental, economic and social factors. LEA also develops methodologies, and carries out the associated risk analyses, within the framework of the HRA. The programme is also part of LEA.

The Technology Assessment (GaBE) programme involves analyses of fossil, nuclear and renewable energy technologies. It is based on an interdisciplinary framework, thus enabling comparisons to be made between current and future options for the electricity, heating and transport sectors.

In the Energy Economics programme, analyses are undertaken of energy systems, and associated technological changes, at the Swiss, European and global levels, all aimed at improving understanding of available options for the realisation of more sustainable energy mixes for the future.

Hot Laboratory Division (AHL)

The Hot Laboratory (Hot Lab) is the largest nuclear research facility under the supervision of the ENSI, and the only Swiss research facility capable of examining large quantities of radioactive materials. The two main tasks of the Hot Laboratory Division are to ensure a safe and efficient utilisation of the Hot Lab infrastructure, and to conduct state-of-the-art service work for the Swiss nuclear industry. Accordingly, AHL offers Hot Lab users modern analytical tools for the manipulation and investigation of radioactive materials. In particular, the laboratory is very well equipped for structural and chemical analyses of the materials used in NPPs and accelerator facilities.

2.8.2. Development of advanced nuclear technologies

Research on future reactors (generation III and IV) at PSI

The ALPHA programme provides confirmation of the characteristics of passive safety systems for advanced LWRs, and is centred on the large-scale, integral test facility PANDA. More recently, the experimental base has been broadened to incorporate investigations of fundamental phenomena in both the primary circuit and containment, and includes the study of two-phase flow phenomena (such as bubbly flows), the prediction of critical heat flux, and mixture/stratification phenomena. A number of additional small- and medium-scale, single-effect test facilities are now also included under the project heading. At all three scales, experimentation is accompanied by the development and application of novel instrumentation techniques able to measure the distributed parameters characteristic of 3D flow fields. In parallel, there is an ongoing development and validation programme for the accompanying numerical tools, particularly CFD, but also including multi-scale modelling approaches to basic phenomena, such as boiling.

In the appropriately named FAST programme, activities are aimed at the development and implementation of a code system representing state-of-the-art safety analyses of nuclear systems incorporating fast neutron spectra.

The High-Temperature Materials programme activities involve characterisation of materials to be used in the future Generation IV reactors (particularly gas-cooled reactors), which will operate at significantly higher temperatures, and are subject to a more intense radiation environment than current Gen II reactors. Mechanistic models are being developed for the prediction of material behaviour, from the atomic level up to the scale of the continuum. Experimental validation of the models is also undertaken using advanced spectroscopic methods and, in particular, synchrotron radiation.

2.8.3. International co-operation and initiatives

The European Atomic Energy Community (EURATOM) was established in 1957 by the Treaty of Rome. In 1978, Switzerland and EURATOM (comprising 15 member states) signed a cooperation agreement in the field of controlled thermonuclear fusion and plasma physics. Based on this agreement Switzerland is participating in the European effort to develop fusion power. This effort includes the participation in the operation of the Joint European Torus JET, the ITER project and other international activities related to plasma and material research.

Since 2004, Switzerland has been fully associated to the Sixth and Seventh Framework programmes of EURATOM. This has enabled Switzerland to extend its cooperation with EURATOM to the fields of general research in the fission domain and the nuclear activities of the European Joint Research Centre JRC.

ENSI supports research into nuclear safety and is represented on more than 70 international commissions and specialist groups working in the field of nuclear safety. It therefore makes an active contribution to new international safety guidelines. Through its network of contacts, ENSI is in touch with current developments in science and technology and discharges its regulatory remit on the basis of global experience in nuclear energy.

In the field of radioactive waste management, international research programmes are carried out in the Mont Terri rock laboratory (Canton of Jura; investigation of the Opalinus Clay; operator: Swisstopo) and the Grimsel test site (Canton of Bern; investigation of crystalline rocks; operator: Nagra).

The Mont Terri rock laboratory provides a platform for international collaboration and the exchange of know-how among researchers, technicians, engineers and scientists. The Federal Office of Topography (swisstopo) operates the rock laboratory and runs the Mont Terri Project. Today, 15 organizations from Belgium, Germany, France, Japan, Canada, Spain, Switzerland and the USA are involved in the underground research project. Various other countries are also considering argillaceous rocks like Opalinus Clay as possible host rocks for deep geological disposal. From 1996 to 2013, the allocated investments in the Mont Terri rock laboratory amount to CHF 68.22 million. Swiss partners contributed more than one third and the other partners about two thirds.

The Mont Terri rock laboratory serves research purposes only. There is no question of disposing of radioactive waste there, on the one hand for geological reasons (folded Jura Mountains), and, on the other hand, because the disposal of any such waste is excluded by the contractual agreement with the Canton of Jura.

The Grimsel Test Site (GTS) was established in 1984 as a centre for underground research and development (R&D) supporting a wide range of research projects on the disposal of radioactive waste. It is located at an altitude of 1730 metres above sea-level in the granitic formations of the Aar Massif. Around 25 partner organisations, as well as universities, research institutes and consulting companies from various countries, are involved in the projects at the Test Site (2010 data). The European Union and the Swiss State Secretariat for Education and Research provide financial support to several experiments.

Like Mont Terri, GTS is a research facility and not a potential repository site; although investigations may utilise a wide range of radioactive tracers, no radioactive waste will be disposed of at the GTS.

2.9. Human resources development

A Master of Science in Nuclear Engineering degree is offered jointly by EPF Lausanne and ETH Zurich, two of Europe’s leading science and engineering universities, in order to qualify multidisciplinary professionals in industry, research and national authorities. The PSI supports the programme by offering its research infrastructure for scientific projects of the students and by assisting in lecturing (for further information on human resources development at PSI refer to section 2.8 above). The programme was launched in 2008 and lasts four semesters, which is compatible with European requirements. The number of graduates has stabilised around 15 per year. Areas covered include the safe and reliable operation of existing and new reactors, the development of novel reactor types, the sustainable supply of nuclear fuel, the closure of the fuel cycle, the disposal of radioactive waste, and many others. The curriculum provides in-depth knowledge of reactor physics, thermal-hydraulics and nuclear materials.

The Institute of Physics of the University of Basel provides a small research reactor. It allows for certain experiments which are not feasible with the reactors of PSI or EPFL. Furthermore, the University of Basel is the only institution in Switzerland with an infrastructure for neutron activation analysis.

The organisation “Nuclear Forum Switzerland” published an overview on Switzerland’s human resources development in the field of nuclear energy (2010 data). It concludes that there are generally enough nuclear specialists trained for current Swiss requirements. However, Switzerland lacks sufficient educational offers in the fields of radiobiology and nuclear physics.

2.10. Stakeholder Communication

The accident at the Fukushima NPP and the suspension of the licensing procedure for new NPPs has triggered a big interest and public debate on the subject of nuclear power. This is likely to be closely followed by the media over the next years.

Governmental communication is focusing on radioactive waste disposal where efforts to keep the public, stakeholders and neighbouring countries informed has been intensified in the context of the ongoing site selection procedure for deep geological repositories. Governmental communication in this field is committed to ensuring a high level of transparency and public participation.

3. NATIONAL LAWS AND REGULATIONS

3.1. Regulatory framework

3.1.1. Regulatory authority(s)

Licensing

The Federal Council is the authority that grants general licenses. The DETEC grants construction licenses and operating licenses for nuclear facilities. The SFOE is responsible for the co-ordination of the licensing procedures and issues licenses for the handling of nuclear materials and radioactive waste.

Supervision

The ENSI is the national regulatory authority in Switzerland with responsibility for nuclear energy. It is supervised by an independent board, the ENSI Board, which is elected by the Swiss Federal Council and reports directly to it.

ENSI is responsible for the supervision of Swiss nuclear facilities, i.e. the NPPs, the interim storage facility for radioactive waste, the nuclear research facilities at the PSI in Villigen, the EPF Lausanne and the University of Basel. Its regulatory remit covers the entire life of a facility, i.e. from initial planning, through operation to final decommissioning including the disposal of radioactive waste. It also includes the safety of staff and the public and their protection from radiation, sabotage and terrorism. In addition, ENSI is involved in the transport of radioactive materials to and from nuclear facilities and in the continuing geoscientific investigations to identify a suitable location for the deep geological disposal of radioactive waste.

ENSI monitors the operation of nuclear facilities:

  • ENSI reviews reporting by the operators, holds regular supervisory discussions and monitors the nuclear facilities (including their organisation and operation) by means of more than 400 on-site inspections each year.

  • Each year in summer, every NPP carries out an inspection lasting several weeks during which maintenance work and repairs are undertaken in the plant.

  • In order to protect staff, the population and the environment, ENSI monitors compliance with the radiation protection regulations and dose limits.

  • ENSI collates all the data obtained during a year into one comprehensive safety assessment, from which it derives any measures that may be required as well as its future supervision plans.

ENSI assesses nuclear facilities:

  • The assessment and monitoring of nuclear facilities are based on laws, guidelines and underlying technical and scientific documentation, which transparently set out the safety requirements and criteria that ENSI applies for its assessments. ENSI continues to develop the underlying documentation and guidelines in accordance with the latest status of science and technology.

  • ENSI draws up safety assessments when operators of nuclear facilities submit applications which go beyond the scope of their existing operating.

  • Applications for modifications to nuclear facilities that are covered by existing operating licenses are dealt with by ENSI, which issues a permit if the decision is positive.

Advisory committee

The NSC is designated as an advisory committee to the Federal Council and the DETEC. It is involved in the licensing process as it reviews and comments on the safety evaluation reports prepared by the supervisory authorities.

Others

In the nuclear field, the supervisory authority with respect to nuclear safety and radiation protection is ENSI. In the non-nuclear field, the supervisory authorities are the Federal Office of Public Health (FOPH) and the public sector insurer SUVA (formerly Swiss National Accident Insurance Fund). The FOPH manages the licensing procedures in the non-nuclear field according to the radiological protection legislation. It is responsible for waste produced from the healthcare sector, industry and research.

The National Emergency Operations Centre – part of the Federal Office of Civil Protection in the Federal Department of Defence, Civil Protection and Sport – is in charge of all emergency situations, including those arising from events at NPPs and relating to the protection of the public and the environment.

Several advisory committees to the government or governmental departments covering aspects of radiological protection, emergency planning and waste disposal have responsibilities associated with the operation of NPPs. However, they are not involved in the licensing process and have no authority over the plants.

3.1.2. Licensing Process

Figure 3 shows the different stages of the licensing process. According to the Nuclear Energy Act, anyone intending to construct or operate a nuclear installation requires a general license. The Federal Council specifies the installations with a low hazard potential which do not require a general license.
