To develop an innovative methodology for efficient and effective social implementation of nuclear power plant PRA, the authors have been developing the automatic AI tools to create fault tree (FT) in "system reliability analysis" of internal event PRA. The automatic AI tools can extract the FT information from the design documents such as paper source-based piping & instrumentation diagram, single-line diagram, etc. The AI tools has been prototyped step by step. Extraction function was extended from the front-line system to support-system. And detail of FT was elaborated from component level to failure mode level. In this meeting, updates of automatic AI tools for FT creation focusing on support-systems is reported.
