Qualification Procedure for PSA Software Referring to STARS-FTA
For the performance and in particular the evaluation of PSAs (level 1) a variety of software approaches is available originated from different countries. Strong and weak points of these tools have been described and discussed in several publications without carrying out a qualification procedure (at least not for the tools used in Germany). In the PSA-guideline  e. g., various software tools are mentioned with respect to the performance of a comprehensive NPP-PSA in the framework of the Periodic Safety Review; in the further developments of this guideline with appendices and corresponding documents (drafts) minimal requirements and features are listed which have to be fulfilled by software used.
