    ChemiGal　plants　and　nuclear　power　plallts　have　been　safeguarded　by　pmtective　instrumentation　systems　which　are usually　equipped　with　sequential　control　circuits。The　c（mtrol　circuits　in　aut（）matic　protective　system　are　required　to achieve　the　object　in　case　of　emergeacy　that　will　occur　in　plants、And　sequential　control　circuits　play　a　very　imp（〕rtant role　in　system　which　deal　with　the　complex　signal　such　as　stand－by　safety　system． In　last　paper，we　have　proposed　the　basic　algorithm　xvhich　searches　signal　path　for　sequential　control　circuit　an〔i constructs　the　fault　tree　and　developed　the　fault　tree　synthesis　system．Ill　this　paper，this　system　is　illustrated　for　more complex　system　and　clari且ed　the　effectiveness　and　the　applicability　of　proposed　method．This　system　is　applied　to　Core Spray　System　Auto　Initiation　Circuit　hl　the　Browns　Ferry　Nuclear　Plant　and　is　shown　to　be　successfully　applied　to　the synthesis　of　fault　tree　for　complex　system．
