t in the design. 3. The PSB reviews the SWS capability to flood the reactor containment should this be required in a post-accident recovery situation. 4. The PSB reviews the system to determine that a malfunction, a failure of a component, or the loss of a cooling source will not reduce the safety- related functional performance capabilities of the system. Specifically, PSB performs the following reviews under the SRP sections indicated: a. Review for 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 structures, systems and components to be protected against externally-generated missiles is performed under SRP Sec- tion 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. In addition, the PSB will coordinate other branches' evaluations that interface with the overall review of the system as follows: The Reactor Systems Branch (RSB) identifies essential components associated with the reactor coolant system and the emergency core cooling systems that are required for operation during normal operations or accident conditions. The RSB establishes accident cooling load functional requirements and minimum time intervals. 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 engineer- ing reviewer of the Engineering Branch (EB) determines the acceptability of the design analyses, procedures, and criteria used to establish the ability of seis- mic Category I structures housing the system and supporting systems to withstand the effects of natural phenomena such as the safe shutdown earthquake (SSE), probable maximum flood (PMF), and tornado missiles as part as 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.
