The December 2000 meeting of the NEA Committee on the Safety of Nuclear Installations (CSNI) accepted a proposal to set up a task group to prepare a report describing research efforts related to wire system ageing in member countries. International organizations working on the topic contributed to this report.
While a significant amount of research has been performed related to wire system ageing and safety, there are still a number of issues that remain unresolved and should be addressed. This report presents a preliminary list of those issues in several areas related to wire system aging and safety. This list represents a good starting point, and it should be updated as new issues are identified. Further, it is proposed that the most effective way to address these issues is through a collaborative research effort in which the expertise and capabilities of various national and international experts can be focused on the resolution of these issues.
