The world’s fleet of nuclear power plants (NPPs) is, on average, more than 20 years old. Even though
the design life of an NPP is typically 30–40 years, it is quite feasible that many plants will be able to
operate in excess of their design lives, provided that NPP engineers demonstrate — through analysis,
testing and ageing management for the equipment and system upgrades, as well as increased vigilance
— that the plants will operate safely. In the operation of NPPs, safety should always be the prime
consideration. Plant operators and regulators must always ensure that plant safety is maintained and,
where possible, enhanced during a plant’s operating lifetime.
The task of managing plant ageing is assigned in most Member States to an engineering discipline
called plant life management (PLiM), which has gained increased attention over the past decade. The
effective ageing management of structures, systems and components (SSCs) is a key element in PLiM
for the safe and reliable long term operation (LTO) of NPPs. Plant life management can be defined in
one sentence as the integration of ageing and economic planning for the purpose of maintaining a high
level of safety and optimizing plant performance by dealing successfully with extended life ageing
issues, maintenance prioritization, periodic safety reviews, education and training.
A PLiM programme is an effective tool that allows an operator to safely and cost-effectively manage
ageing effects in SSCs for LTO. Such a 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 International Atomic Energy Agency (IAEA) organized earlier International Conferences on
Nuclear Power Plant Life Management from 4 to 8 November 2002 in Budapest, Hungary, from 15 to
18 October 2007 in Shanghai, China, and from 14 to 18 May 2012 in Salt Lake City, United States of
America. The participants of these earlier conferences appreciated greatly the opportunity they offered
for information exchange in this field and recommended that the IAEA continue to organize future
conferences regularly every four to five years. Accordingly, the IAEA is organizing the fourth
conference in the series from 23 to 27 October 2017 in Lyon, France.
