Revision of AESJ Standard "The Code of Implementation of Periodic Safety Review of Nuclear Power Plants"

Hirano, Masashi; Narumiya, Yoshiyuki*

The Periodic Safety Review (PSR) was launched in June 1992, when the Agency for Natural Resources and Energy issued a notification that required licensees to conduct comprehensive review on the safety of each existing nuclear power plant (NPP) once approximately every ten years based on the latest technical findings for the purpose of improving the safety of the NPP. In 2006, the Standard Committee of the Atomic Energy Society of Japan established the first version of "The Standard of Implementation for Periodic Safety Review of Nuclear Power Plants: 2006". Taking into account developments in safety regulation on PSR after the issuance of the first version, the Standard Committee has revised the Standard. This paper summarizes background on PSR, such developments and major contents of the Standard as well as the focal points of the revision.
