g a design basic accident (DBA), LOCA, or any other primary system pipe break. CSBSCSB evaluates the functional capability of the containment and subcompartments for the 32 spectrum of loss-of-coolant events under SRP Section 6.2.1. CSBSCSB, on request from the RSBSRXB, also provides an evaluation of containment pressure calculations utilized in the reflood portion of the ECCS performance analyses. MEBEMEB is responsible for the review of the effects of blowdown loads on core support 33 structures and on control rod guide structures. MEBEMEB verifies that the core remains in place in case of a LOCA and that the control rods can be inserted. MEBEMEB is also responsible for evaluating the effects of blowdown loads, including jet forces on the piping of the reactor coolant system and on the support structures of the components of the reactor coolant 15.0-5 DRAFT Rev. 3 - April 1996 system. MEBEMEB verifies that acceptable criteria have been employed in the design of the reactor coolant system and its supports to prevent failures in the reactor coolant pressure boundary or in engineered safety feature equipment in the event of a LOCA.
