Fifth International Conference on Nuclear Power Plant Life Management

16–19 May 2022, Osaka, Japan

Fifth International Conference on Nuclear Power Plant Life Management 2022

Background

The capacity weighted age of the world’s operating nuclear power plants (NPPs) is, on average, more than 30 years old. Even though the design life of an NPP is typically 30–40 years, the operational lifetime of many plants is, following a comprehensive review, extended. To enable this, NPP engineers have demonstrated — through analysis, testing and ageing management for equipment and system upgrades — that the plants can continue to operate safely and reliably. Plant operators and regulators must ensure safety is maintained and, where possible, enhanced during a plant’s operating lifetime. Reliability and performance are becoming increasingly important, especially for ageing NPPs. Low electricity prices in many markets and investment requirements to maintain, replace or modernize ageing components threaten the economic viability of operating plants, in some cases with many years remaining on approved licenses.

In most Member States, the task of ageing management is assigned to an engineering discipline called plant life management (PLiM), which has gained increased attention over the past two decades. 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 as the integration of ageing and economic planning for the purpose of maintaining a high level of safety and optimizing plant performance by addressing extended life ageing issues, maintenance prioritization, periodic safety reviews, education and training.

A PLiM programme is an effective tool that allows an operator to manage ageing effects in SSCs for LTO in a safe and cost‑effective manner. Such a programme helps facilitate decisions regarding when and how to repair, replace or modify SSCs in an economically optimized manner, while maintaining a high level of safety.

The IAEA previously organized 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, from 14 to 18 May 2012 in Salt Lake City, United States of America and from 23 to 27 October 2017 in Lyon, France. Participants in these earlier conferences greatly appreciated the opportunities for information exchange and recommended that the IAEA continue to organize conferences every four to five years. Accordingly, the IAEA is organizing the fifth conference in the series from16 to 19 May 2022 in Osaka, Japan.

Purpose and Objectives

The objectives of the conference are to:

  • Emphasize the role of PLiM programmes in assuring safety and improving reliable NPP operation;

  • Identify the economic impacts of PLiM and LTO programmes, as well as methodologies for their evaluation;

  • Provide key elements and good practices related to the safety aspects of ageing, ageing management and LTO;

  • Provide a forum for information exchange on national and international policies, regulatory practices, and for the demonstration of strategies, including their application in ageing management and PLiM programmes for operating and new NPPs; and

  • Exchange lessons learned from managing NPP PLiM during the global pandemic.

List of Topics

Papers are invited on the following below-mentioned subject areas:

Approaches to Plant Life Management: Best practices in, the application of PLiM for LTO from the safety and economic point of view. Topics to be addressed in the presentations include:

  • Implementation of the lessons learned from the severe accident at the Fukushima Daiichi NPP and their implications for LTO;
  • Methodology and scope, terms and definitions for the development of PLiM and LTO programmes and their implementation;
  • Methodology for integrated plant assessments, including the condition of SSCs;
  • Selection criteria for NPPs for LTO; and
  • New NPP design features that consider PLiM experiences and feedback.

Economics of Plant Life Management: How to improve the economic performance of NPPs through PLiM. Topics to be addressed in the presentations include:

  • Potential business opportunities and risks, including power uprating issues related to PLiM;
  • Cost-effective strategies for modernization and replacement/refurbishment of SSCs;
  • Economic analysis for decision making on LTO;
  • Cost-effective technologies/practices for maintenance, inspection and surveillance;
  • Supply chain health, equipment obsolescence and commercial grade dedication
  • Premature shutdown preparation strategy and procedures, including technical aspects;
  • Long term strategies for spent fuel storage (on-site) and waste management;
  • Replacement of large components (e.g. steam generators, reactor vessel heads and turbine generators);
  • Flexible operation in response to increased grid variability;
  • Innovative solutions that address LTO challenges and help ensure operational sustainability; and
  • NPP PLiM and the dawn of Integrated Energy Systems.

Ageing Management and Preparation of Long-Term Operation: Technical updates on ageing management issues for mechanical, electrical/instrumentation and control (I&C) components and civil structures, as well as to discuss challenges related to the preparation of safe LTO. Topics to be addressed in the presentations include:

  • Safety standards to support LTO;
  • Scoping and screening of SSCs for LTO;
  • Ageing management review;
  • Use of the experience gained from implementation of the International Generic Ageing Lessons Learned (IGALL) programme;
  • Development, implementation and improvement of effective ageing management programmes;
  • Revalidation of time-limited ageing analysis;
  • Technological obsolescence;
  • Research to support LTO and ageing management;
  • Inspection methodologies and strategies for significant components; and
  • In-service inspection and non-destructive examination.

Configuration and Modification Management for Safety Enhancement and improved reliability: Safety enhancement, design modernization, refurbishment and replacement programmes for ageing SSCs, obsolescence and additional safety requirements. Topics to be addressed in the presentations include:

  • Aspects of SSC design modification, modernization, innovation, refurbishment and replacement;
  • Maintenance optimization through predictive maintenance, preventive maintenance and corrective maintenance;
  • Risk and reliability evaluation of components and piping;
  • Modification and configuration management, including design basis reconstitution;
  • Accident tolerant fuel assemblies;
  • Safety analysis for design modification considering internal/external hazards;
  • Effective management of I&C, including modernization, methods and tools; and
  • Lessons learned from the planning and implementation of advanced I&C systems.

Stakeholder Engagement, Human Factors and Managerial Aspects: Experiences and lessons learned in relation to system management and the successful resolution of the technical issues and challenges presented in the previous sessions, and to identify human factors and managerial aspects of the field.
