The Committee on the Safety of Nuclear Installations (CSNI), at its meeting in June 2003, agreed to conduct a survey to collect information that help to identify common needs and area of potential co-operative activities based on experiences, status of existing data and research programs, and regulatory requirements and practices in NEA member countries.
This report provides a summary of the results of the questionnaire on PWSCC and Ni-based alloys. The main aim of the questionnaire was to obtain a comparison between the operating experience, inspection practices and acceptance criteria applied in the different countries. It was also considered of relevance to compare experience and practices with Alloy 690, which is being used to a large extent in replacement components, as well as research activities in this area. Participants in the questionnaire were encouraged to include any other information that they considered being useful for a better understanding of the PWSCC phenomenon.
