A. Background
The world’s fleet of nuclear power plants is, on average, more than 20 years old. Even though the design life of a nuclear power plant is typically 30–40 years, many plants will operate in excess of their design lives, provided that nuclear power plant engineers demonstrate by analysis, equipment and system upgrades, increased vigilance, testing and ageing management that the plant will operate safely. In the operation of nuclear power plants, safety should always be the prime consideration. Plant operators and regulators must always ensure that plant safety is maintained and, where possible, enhanced during its operating lifetime.
Nuclear power plant life management (PLiM) has gained increased attention over the past decade, and effective ageing management of systems, structures and components (SSCs) is a key element in PLiM for the safe and reliable long term operation of nuclear power plants. A PLiM programme is an effective tool that allows an operator to safely and cost effectively manage ageing effects in SSCs for long term operation (LTO). A PLiM programme helps facilitate decisions concerning when and how to repair, replace or modify SSCs in an economically optimized way, while assuring that a high level of safety is maintained. The option for extended nuclear power plant operation has been recognized by operators and regulators alike, as evidenced in the number of licence renewal programmes that are being developed by Member States.
After the severe accident at the Fukushima Daiichi nuclear power plant, the safe operation of nuclear power plants has become even more important; not only in terms of technical or ageing issues, but also in terms of management system and qualified workforce related issues. Application of an integrated management system and structured workforce planning are needed throughout the plant life in order to ensure effective plant organization and management.
The IAEA organized the first and second International Conference on Nuclear Power Plant Life Management respectively from 4 to 8 November 2002 in Budapest, Hungary, and from 15 to 18 October 2007 in Shanghai, China. Participants at the first and second conferences placed a high value on information exchange and recommended that similar conferences be organized within four to five years. Mindful of the importance of a periodic state of the art information exchange, the IAEA is organizing the third International Conference on Nuclear Power Plant Life Management from 14 to 18 May 2012 in Salt Lake City, USA. This conference will focus on topical issues affecting PLiM and thus is expected to be of particular interest to staff of utilities, research and design organizations, regulatory bodies, manufacturing and service companies, as well as government decision makers concerned with near, medium and long term energy needs.
B. Objective of the Conference
The objectives of the third international conference on PLiM are to:
• Emphasize the role of PLiM programmes in assuring safe and reliable nuclear power plant operation;
• Provide a forum for information exchange on national and international policies, regulatory practices and safety culture and to demonstrate strategies, including application in an ageing management and PLiM programme;
• Provide key elements and good practices related to the safety aspects of ageing, ageing management and long term operation;
• Identify the economic impacts of PLiM programmes and methodologies for their evaluation;
• Help Member States further develop their PLiM programmes taking advantage of the latest available technology.
C. Programme Structure and Topics
To facilitate the conference objectives, each topical session will have the following format:
• A keynote speaker, who will present a paper by invitation;
• A set of presentations that supplement specific areas within the topical session and stimulate discussion among conference participants;
• A set of detailed technical papers that present the state of the art of the subject area.
C.1. Opening Session: Opening, plenary and keynote presentations
