In December 2000, the Committee on Nuclear Regulatory Activities (CNRA) and the Committee on the Safety of Nuclear Installations (CSNI) agreed to prepare a state-of-the art report addressing the present situation and regulatory aspects in NEA member countries on:

  • risk-based/risk-informed in-service inspections developments;
  • qualification of NDT system to be used for the inspections.

The CSNI gave mandate to the CSNI Working Group on the Ageing and Integrity of Components and Structures (WGIAGE) to prepare the report.
