Two subjects – stress corrosion cracking (SCC) and degradation of cable insulation – were selected as the focus of the SCC and Cable Ageing Project (SCAP) due to their relevance for plant ageing assessments and their implications on nuclear safety. In order to achieve that goal, 14 NEA member countries joined the project in 2006 to pool their knowledge, and three additional countries joined during the course of the project. The International Atomic Energy Agency (IAEA) and the European Commission participated as observers.

The objective of this internationally co-ordinated project was to share the corporate knowledge and operating experience to understand the failure mechanisms and identify effective techniques and technologies to effectively manage and mitigate active degradation in nuclear power plants.

This report summarises the product of SCAP work resulting from four years of technical interactions and shared knowledge from all participants from June 2006 to June 2010.
