Development and utilization of indicators to summarize and represent performance of nuclear power plants

We have developed eight performance indicators (PIs) that enable quantitative and overall comprehension of operating performance. Among these eight indicators there are 'capability factor' 'incidents and failures' and 'radiation exposure and radioactive wastes', all used to represent the safety and reliability of a nuclear power plant. Results of analysis and evaluation by means of these PIs are distributed to the regulatory agency and other organizations every year, for the benefit of all involved. We have also been examining a technique that may allow synthesis of these PIs into a single, simpler comprehensive indicator that covers all aspects of plant performance. In this report, we present analysis and evaluation of the PIs, the technique to provide a comprehensive performance indicators and actual application. (author)
