nder the SRP sections indicated: The Equipment Qualification Branch (EQB) eEvaluates the operability of pumps and valves and judges the design criteria for pressure-relieving devices which may have an active function during and after a faulted plant condition against the requirements of therelated to component operability assurance and seismic qualification programs, as 16 part of its primary review responsibility for SRP Section 3.10.17 In addition, the MEBEMEB will coordinate other branches evaluations that interface with the 18 overall review of this SRP section as follows:19 A. The Auxiliary Systems Branch (ASB)Plant Systems Branch (SPLB) verifies that the 20 21 number and size of valves specified for the steam and feedwater systems have adequate pressure-relieving capacity as part of its primary review responsibility for SRP Section 10.3. B. The Reactor Systems Branch (RSBSRXB ) verifies that the number and size of valves 22 specified for the reactor coolant pressure boundary have adequate pressure-relieving capacity as part of its primary review responsibility for SRP Section 5.2.2. The SRXB reviews the design of systems and components that interface with the reactor coolant system with regard to intersystem loss-of-coolant accidents (ISLOCA) as part of its primary review responsibility for SRP Section 3.12 (proposed). The SRXB also 23 verifies that the applicant has identified and addressed piping connected to the reactor colant system that is subject to thermally stratified flow, thermal striping, and/or thermal cyclic effects, for residual heat removal and emergency core cooling systems, as part of its primary review responsibility for SRP Sections 5.4.7 and 6.3.24 C. The Containment Systems and Severe Accident Branch (SCSB) reviews the applicant's 25 analyses of subcompartment differential pressures resulting from postulated pipe breaks as part of its primary review responsibility for SRP Section 6.2.1.2.
