CSNI Technical Opinion Papers No. 4: Human Reliability Analysis in Probabilistic Safety Assessment for Nuclear Power Plants

摘要

The mission of the Working Group on Risk Assessment (WGRisk) is to advance the understanding and utilisation of probabilistic safety assessment (PSA) in ensuring continued safety of nuclear installations in member countries. In pursuing this goal, the Working Group shall recognise the different methodologies for identifying contributors to risk and assessing their importance. While the Working Group shall continue to focus on the more mature PSA methodologies for Level 1, Level 2, internal, external, shutdown, etc., it shall also consider the applicability and maturity of PSA methods for evolving issues such as human reliability, software reliability and ageing issues, as appropriate. The WGRisk mandate states that: "The Working Group shall constitute a forum for exchange of information and experience of activities related to risk assessment in member countries. WGRisk shall prepare opinion papers on questions regarding the applicability of various aspects of risk assessment, results, insights and interactions with other analysis techniques to matters affecting nuclear safety or nuclear safety research. This shall include identifying and prioritising important regulatory issues requiring additional research."
