pumps. e. Instrumentation and control features necessary to accomplish design functions, including isolation of components to deal with leakage or malfunctions and actuation requirements for redundant equipment. f. A simplified reliability analyses using event-tree and fault-tree logic techniques. 3. ASB also performs the following reviews under the SRP sections indicated: a. Review of flood protection is performed 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, and d. Review of high and moderate energy pipe breaks is performed under SRP Section 3.6.1. In addition, the ASB will coordinate other branches evaluations that interface with the overall review of the system as follows. The Reactor Systems Branch (RSB) will identify engineered safety feature components associated with the reactor coolant system and the emergency core cooling systems that are required for operation during normal operations, transients, and accident conditions. 9.2.2-2 Rev. 2 - April 1984 RSB will establish cooling load functional requirements and minimum time inter- vals associated with safety-related components. The RSB performs these reviews as part of its primary review responsibility for SRP Sections 5.4.7, 5.4.8, 6.0, and 15.0. The Structural and Geotechnical Engineering Branch (SGEB) will determine the acceptability of the design analyses, procedures, and criteria used to establish the ability of Category I structures that house the system and supporting systems to withstand the effects of natural phenomena such as the 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, 3.7.4, 3.8.4 and 3.8.5.
