., auxiliary feedwater systems) after anticipated operational occurrences and postulated accidents, and reviews the operability of reactor primary system components.10 Auxiliary Systems Branch (ASB) - evaluates the operation and performance of the auxiliary systems following anticipated operational occurrences and postulated accidents (i.e., auxiliary feedwater systems).11 Mechanical Engineering Branch (EMEB) - evaluates the mechanical design of the reactor 12 primary system and components, pipe restraints, and other safety-related mechanical components and classification of structures, components, and systems. The Equipment Qualification Branch (EQB) - reviews the operability of reactor primary system components.13 Containment Systems and Severe Accident Branch (SCSB) - evaluates the response of the 14 containment to postulated accidents. Severe accidents (i.e., beyond design basis) and Eevents such as fires, floods, storms, or 15 earthquakes are not explicitly considered in the review of anticipated operational occurrences and postulated accidents in Chapter 15. Rather, the requirements to design for these events are reviewed under other Standard Review Plan (SRP) sections, as listed in Table 15-1 (attached). 16 The reviewers are responsible for the selection and emphasis of aspects of the reviews of anticipated operational occurrences and postulated accidents in this chapter. Judgment on the areas to be given attention during each review is based on an inspection of the information provided, the similarity of this material to that recently reviewed on other plants, and whether items of special or unique safety 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
