fety significance are involved. The Reactor Systems Branch reviews the majority of anticipated operational occurrences and postulated accidents as indicated in the SRP sections for Chapter 15. Various anticipated process disturbances, equipment malfunctions, potential operator actions or errors, and component failures are examined to evaluate the plant capability to control or accommodate such failures and malfunctions. The RSB review includes an analysis of the pressure to which the reactor and steam systems are subjected and the need for engineered safety features to mitigate the consequences. The impact of various single failures on the course of anticipated operational occurrences and postulated accidents is also considered. The transient and accident sequences are reviewed to identify necessary operator actions and to confirm that actions prescribed by procedures developed under Action Plan Item I.C.1 have been appropriately accounted for. The Procedures and Test Review Branch, upon request, will assist the RSB reviewer in identifying all prescribed operator actions. As required by Item II.K.3.44 of NUREG-0737, BWR applicants must demonstrate that for anticipated transients combined with the worst single failure and assuming proper operator actions, the core remains covered or provide analysis to show that no significant fuel damage results from core uncovery. Transients which result in a stuck-open relief valve should be included in this category. This may be demonstrated by plant-specifit analyses or reference to applicable generic analyses. Generic analyses are considered applicable if geometry and input conditions used for the analyses are representative or bounding. The Core Performance Branch is responsible for the review of all reactor physics data presented in this chapter. This includes power levels, power distributions, doppler coefficients, moderator temperature coefficients, void coefficients, reactor kinetics parameters, and control rod worths. The
