Evaluation of risks associated with AOT and STI requirements at the ANO-1 nuclear power plant
Technical Report
·
OSTI ID:6830290
This report presents an evaluation of the core-melt frequency contributions associated with Allowed Outage Times (AOTs) and Surveillance Test Intervals (STIs) at Arkansas Nuclear One--Unit 1 (ANO-1). The results show that the core-melt frequency contributions from present AOTs and STIs vary by more than four orders of magnitude (a factor of 10,000). This wide range of variation indicates the wide range of the risk importance of present AOTs and STIs. The core-melt contributions from specific AOTs and STIs can be used to prioritize those components which should be focused on for inspection activities, personnel training, and reliability program activities that are involved with surveillanc testing and corrective maintenance. 10 refs., 11 figs., 41 tabs.
