Bilan priodique de la sret des centrales nuclaires en service

This guide supplements Safety Series No. 110: The Safety of Nuclear Installations, a safety fundamentals publication, and Safety Series No. 50-C-O (Rev. 1): Code on the Safety of Nuclear Power Plants: Operation. It primarily provides guidance on the conduct of a periodic safety review (PSR) of an operational nuclear power plant. A PSR is designed to take a comprehensive account of improvements in safety standards and operating practices, cumulative effects of plant ageing, modifications and feedback of operating experience, and developments in science and technology that have occurred over a ten year period. PSRs provide the means for determining necessary or worthwhile changes aimed at maintaining high levels of plant safety and harmonizing the safety of older plants with that of modern plants.
