Description (excerpt):
Common cause failure (CCF) events can significantly impact the availability of the safety systems of nuclear power plants. For this reason, several countries initiated the International Common-Cause Failure Data Exchange (ICDE) Project in 1994. In 1997, the Nuclear Energy Agency (NEA) Committee on the Safety of Nuclear Installations (CSNI) formally approved this project to be carried out within the NEA framework. Since then, the project has operated over eight consecutive terms. Phase 9 started in January 2023 and will end in December 2026.
The purpose of the ICDE Project is to allow multiple countries to collaborate and exchange common cause failure (CCF) data to enhance the quality of risk analyses that include CCF modelling. Because CCF events are typically rare, most countries do not experience enough CCF events to perform meaningful analyses. Data combined from several countries, however, yield sufficient material for more rigorous analyses.
