Technical Meeting on
Activities related to International Generic Ageing Lessons Learned Database

18-20 May 2009
IAEA Headquarters, Vienna, Austria



The technical meeting to summarize and to discuss the draft working material on International Generic Ageing Lessons Learned (IGALL) Database with Member States (MS) was held on 18-20 May 2009. 20 Member States, EC-JRC, OECD/NEA, and ASME participated in the meeting.

The meeting provided some recommendations for the next Consultancy Meeting to be held in October 2009. The conclusions of the meeting were:

  • USNRC GALL report is instrumental for establishment of a state-of-the-art IGALL report, an international as well as guidance for recommendable ageing management programmes for existing and future NPPs.

  • The IGALL report should be the ground for implementation of recommendable ageing management programmes (AMPs) for NPPs with diverse technologies (PWR, BWR, WWER, CANDU, PHWR). It should be developed as a practical guide to assist MS in implementing, maintaining and improving effective AMPs at the NPPs.

  • The IGALL report should be a fundamental document in supporting a systematic approach to managing ageing of a variety of structures or components as described in the Safety Guide NS-G-2.12.

  • In order to achieve this, attention should be given to:

    1. Establishment, development and maintenance of a report containing relevant consolidated international information with regard to the degradation mechanisms of systems, structures, components (SSCs) such as recommended inspection techniques, foreseen degradation locations, recommended mitigation means, recommended technologies for inspection and repair, monitoring and surveillance, water chemistry, lessons learned from international past events.

    2. Compilation of state-of-the-art methodologies for evaluation of the extent of the degradation of a component.
