Safety system functional inspections (SSFIs) have become important tools for both the regulator and utilities to assure that plant systems important to safety will function as designed. The Washington Public Power Supply System (WPPSS) has initiated an SSFI program to verify that the design-basis documentation of plant systems is adequate. This paper describes the application of probabilistic risk assessment (PRA) methods to support the SSFI of the WNP-2 alternating current (ac) power system. Performing SSFIs can be a very resource-intensive process. The application of PRA methods to focus the SSFI on the components important to safety allowed WPPSS to efficiently utilize their resources and reduce the cost of the overall SSFI effort.
