c3. For both PWRs and BWRs, the ASB SPLB reviews the component cooling or 24 service water systems that transfer decay heat from the RHR system to the ultimate heat sink as part of its primary review responsibility for SRP Sections 9.2.1 and 9.2.2. d4. The RSB SRXB reviews the design and operating characteristics of the RHR 25 system with respect to its shutdown and long-term cooling function. Where the RHR system interfaces with other systems (e.g., RCIC system, component cooling water system) the effect of these systems on the RHR system is reviewed. DRAFT Rev. 4 - April 1996 5.4.7-4 Overpressure protection provided by the valving between the RCS and RHR system is also reviewed. In addition, the Reactor Systems Branch will coordinate evaluations of other branches that interface with the overall review of the RHR system as follows: 1. The Containment Systems and Severe Accident Branch (SCSB) performs the following reviews:26 a. SCSB reviews the containment heat removal capability and the containment sump designs as part of its review responsibility for SRP Section 6.2.2.27 b. SCSB verifies that portions of the RHR system penetrating the containment 28 barrier are designed with acceptable isolation features to maintain containment integrity for all operating conditions including accidents as part of its primary review responsibility for SRP Section 6.2.4;.29 2. The Structural and Geotechnical Engineering Branch (SGEB) Civil Engineering and Geosciences Branch (ECGB) determines the acceptability of the design analysis, 30 procedures and criteria used to establish the ability of seismic Category I structures housing the system and supporting systems to withstand the effects of natural phenomena such as safe shutdown earthquake (SSE), the probable maximum flood (PMF), and tornado missiles as part of its primary review responsibility for SRP Sections 3.3.1, 3.3.2, 3.5.3, 3.7.1 through 3.7.4, 3.8.4 and 3.8.5. The ECGB also verifies that inservice inspection requirements
