The International Atomic Energy Agency in co-operation with the RERTR Programme managed by the Argonne National Laboratory for the United States Department of Energy, is hosting the "RERTR-2004 International Meeting on Reduced Enrichment for Research and Test Reactors". This will be the 26th meeting of a series on the same general subject. The previous meetings were held at ANL (1978), Saclay, France (1979), ANL (1980), Jülich, Germany (1981), ANL (1982), Tokai, Japan (1983), ANL (1984), Petten, The Netherlands (1985), Gatlinburg, Tennessee (1986), Buenos Aires, Argentina (1987), San Diego, California, (1988), Berlin, Germany (1989), Newport, Rhode Island (1990), Jakarta, Indonesia (1991), Roskilde, Denmark (1992), Oarai, Japan (1993), Williamsburg, Virginia (1994), Paris, France (1995), Seoul, Korea (1996), Jackson Hole, Wyoming, (1997), São Paulo, Brazil (1998), Budapest, Hungary (1999), Las Vegas, Nevada (2000), Bariloche, Argentina (2002) and ANL (2003).

You are cordially invited to attend this meeting, where information will be exchanged on the progress of national and international Programmes to develop low enriched fuels and targets for research and test reactors and to convert the reactors to such fuels and targets. The meeting will be held in English and will be open to the public, but the Meeting Secretariat reserves the right to limit the attendance.

The main objective of this series of meetings is the core conversion of research reactors from HEU to LEU fuels. Fuel element manufacturers and national laboratories have developed fuel types suitable for LEU utilization in most of the world´s research reactors. Many reactors are already fully converted and new promising LEU fuels are under development and scheduled for early qualification

You are encouraged to present a paper at the meeting. If you intend to do so, please indicate this intention on the attached Registration Form and send an abstract of the paper, as soon as possible, but not later than 27 August 2004 to the Meeting Secretariat (please see Instructions for Authors and Typists and Form for Publication Release). The presentation of each paper will be limited to 20 minutes. If you intend to participate without presenting a paper, please send only the completed Registration Form by the same deadline. Please observe the Instruction for Forms and Deadlines.

All papers will be distributed at the meeting and will be published in the proceedings by the Argonne National Laboratory.

Topics to be covered during the meeting are:

  • Progress reports of national Programmes
  • Fuel development
  • Fuel testing and evaluation
  • Measurements and calculations for converted reactors
  • Safety tests and evaluations
  • Core conversion studies
  • Production of fission Mo-99 from LEU

On Friday, 12 November 2004, the meeting participants will have an opportunity to participate in either one of the two technical visits to the:

  1. Research Reactor at the Atominstitut der Österreichischen Universitäten in Vienna, Austria or
  2. Budapest Research Reactor at the KFKI Atomic Research Institute in Budapest, Hungary.

1. Research Reactor Atominstitut, Vienna:

The 250 kW TRIGA Mark-II reactor operates since March 1962 at the Atominstitut Vienna/Austria. Ever since operation of the reactor has averaged 220 days per year, without extended outages. Therefore, the small research reactor is very well utilized.

The Atominstitute´s main tasks are education on nuclear topics and training in the fields of neutron- and solid state physics, nuclear technology, reactor safety, radiochemistry, radiation protection and dosimetry, as well as low temperature physics and fusion research. In addition, the Atominstitut co-operates closely with the IAEA in research projects, coordinated research programs (CRP) and provides also expert services.

This TRIGA Mark-II is equipped with a number of irradiation devices:

5 reflector irradiation tubes
1 central irradiation tube
1 slow pneumatic transfer system (transfer time 4 seconds)
1 vertical fast pneumatic transfer system (transfer time 0.3 seconds)
1 horizontal fast pneumatic transfer system (transfer time 20 milliseconds)
4 neutron beam ducts
1 thermal column
2 neutron radiography facilities
09:30 Bus will leave from the VIC
10:00 - 12:00 Introduction and tour of the
12:30 - 14:00 Lunch at Restaurant "Amon"
14:30 Return to the VIC

Participation in the tour, which will include transportation and lunch, will require a payment of € 20.-.

2. Budapest Research Reactor, Budapest:

The Budapest Research Reactor (BRR) is a tank-type reactor, moderated and cooled by light water. The reactor is of Russian origin, it went critical in 1959. The thermal power was at that time 2 MW. The first upgrading took place in 1967 when the power output was increased from 2 MW to 5 MW, using a new type of fuel and a beryllium-reflector. After 27 years of operation, a full-scale reactor reconstruction and upgrading project began in 1986. The upgraded 10 MW research reactor was relicensed on 25 November 1993. According to Hungarian safety regulations a periodic safety review (PSR) was conducted in 2002-2003, as a result the operation license was renewed for another ten years.

Reactor type: Light-water cooled and moderated tank-type reactor with beryllium reflector
Fuel: VVR-SM(-M2)
Nominal thermal power: 10 MW
Mean power density in the core: 61,2 kW/l
Neutron flux density in the core: 2,5 * 1014 n/cm2s (thermal in the flux trap)1 * 1014 n/cm2s (approx. max. fast flux in the fast channel)

The BRR is used for irradiation and neutron research. The reactor has more than 60 channels and ten beam ports. The beam ports with the research facilities are installed in the reactor hall and neutron.

Tentative Programme:
07:00 Bus will leave from the VIC
10:30 - Welcome coffee/tea
11:00 - Presentations and visit of the reactor and utilization facilities
12:30 - Lunch
13:30 - Guided sighseeing tour by bus through Budapest
17:00 Departure to Vienna

Participation in the tour, which will include transportation and lunch, will require a payment of € 50.-

Participants who wish to visit the Budapest Research Reactor have to apply for a Schengen visa for multiple entry and if they require a visa for entering Hungary should contact the nearest consular representative of Hungary as early as possible.

Participants planning to stay in Budapest for the weekend, please see the attached Package Information and Booking Form provided by American Express Travel Service.


The official currency is Euro (€): Conversion rate for 1 US$ = € 0.820 (July 2004).

It is recommended to change money at banks, which are open daily from 9:00 to 15:00 hrs.

All major credits cards such as American Express, Diners Club, Master Card and Visa are equally accepted in the hotels, restaurant, shops etc.


Electrical current in Austria is 230 V AC 50 Hz. Round, European-style two-pin plugs are used. Appliances designed to operate on 110/120 V need a voltage converter and a plug adapter.


The temperature this time of the year ranges between 3 to 8 degrees Celsius.
