Description

In 1979, TVA started emphasizing reliability and availability engineering for its nuclear plants when it began a program for the development of availability and safety models for the Sequoyah Nuclear Plant (SON). In 1980, TVA made a commitment to probabilistic risk assessment (PRA) by initiating a full-scope PRA study for the Browns Ferry Nuclear Plant (BFN). Although PRA was relatively new to the nuclear power industry, TVA believed the benefits were identifiable and the commitment of money and manpower was considered justified. As our work has progressed, TVA has realized that the benefits of PRA extend much farther than just the evaluation of public risk. This paper describes how PRA has been used at TVA to reduce plant costs and also to provide some insight as to how this technology is intended to be used to address present and future TVA needs. Several observations from experience with PRA are also provided
