The Babcock & Wilcox and United Engineers and Constructors advanced light water reactor (ALWR) design has features that will provide enhanced safety, reliability, and design margin over the current generation of commercial nuclear power plants. The B-600 ALWR is a 600-MW(electric) two-loop pressurized water reactor (PWR). A probabilistic analysis has been performed to provide early feedback to the designers to enhance the reliability of the safety systems. Based on this information, the ALWR designers have eliminated most of the features that dominate the risk profile in conventional PWRs. This has resulted in the calculated core damage frequency for the ALWR being better than the design targets.
