ed under SRP Section 3.4.1; b. Review of the protection against internally-generated missiles is performed under SRP Section 3.5.1.1; c. Review of the protection of structures, systems, and components against the effects of externally-generated missiles is performed under SRP Sections 3.5.1.4 and 3.5.2; d. Review of high and moderate energy pipe breaks is performed under SRP Section 3.6.1; and e. Review of fire protection is performed under SRP Section 9.5.1.; and f. Review of the test program for monitoring the heat transfer capability of safety- related heat exchangers cooled by service water under SRP Section 9.2.1. If such tests indicate degradation in heat transfer capability that cannot be remedied by maintenance of the service water system, closed loop cooling systems such as the Reactor Auxiliary CWS reviewed under SRP 9.2.2 should be included in the scope of the inspection and maintenance program for service water systems, also reviewed under SRP 9.2.1.13 2. The PSBSPLB will coordinate other branches evaluations that interface with the overall 14 review of the system as follows: a. The Reactor Systems Branch (RSB)(SRXB) will identify engineered safety 15 feature components associated with the reactor coolant system and the emergency core cooling systems that are required for operation during normal operations, transientsanticipated operational occurrences, and accident conditions. 16 (RSB)The SRXB will establish cooling load functional requirements and 17 minimum time intervals associated with safety-related components. The (RSB)SRXB performs these reviews as part of its primary review responsibility 18 for SRP Sections 5.4.7, 5.4.8, 6.0, and 15.0. b. The structural and geotechnical engineering reviewer of the Engineering Branch (EB) Civil Engineering and Geosciences Branch (ECGB) will determine the 19 acceptability of the design analyses, procedures, and criteria used to establish the ability of Category I structures that house the system and supporting
