The Use of PRA in Designing the Westinghouse AP600 Plant
A full-scope Level 3 Probabilistic Risk Assessment (PRA) has been performed for the Westinghouse-designed advanced passive light-water reactor (AP600) [1], The PRA study estimates the core damage frequency and release frequency of the AP600 design for both power and shutdown conditions. The analysis also includes an internal fire PRA and an internal flood PRA. A seismic margins analysis has been performed to evaluate the plant’s capability to withstand seismic events. Westinghouse designers and PRA analysts worked closely together for over five years to assess the safety of a variety of passive plant design configurations.
