Abstract: This paper describes the key points of the completed and ongoing regulatory activities in order to revise the existing guide on probabilistic safety analyses (PSA guide) and its corresponding technical documents, both as parts of sublegal regulations in Germany. The German PSA guide covers the fundamental requirements concerning the execution of PSAs in the frame of comprehensive safety reviews. The technical details regarding the performance of PSA are set out in two technical documents (PSA methods and PSA data) that have been developed by a working group of PSA experts. Based on the experiences from the first series of periodic safety reviews (PSRs), international experience and the fact that PSR has been mandatory in Germany since April 2002, revisions of all guides are under way. The first guide to have been updated is the PSA guide, together with the corresponding technical documents, that were republished in 2005.

Keywords: fundamental requirements; probabilistic safety analysis; PSA; regulatory guidance; regulatory activities; safety reviews; sublegal regulations; technical documents; nuclear power plants; nuclear energy; nuclear safety; Germany.
