he system. 4. ASB also performs the following reviews under the SRP sections indicated: 10.3-2 Rev. 3 - April 1984 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 Section 3.5.2. d. Review of high- and moderate-energy pipe breaks is performed under SRP Section 3.6.1. In the review of the main steam supply system, the ASB and 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 portion of the MSSS inside the primary containment that are required for normal operations and accident conditions, establishes shutdown cooling load requirements versus time, and verifies the design transient used in establishing the flow capacity and setpoint(s) of steam generator relief and safety valves as part of its primary review responsibility for SRP Section 5.2. The Structural and Geotechnical Engineering Branch (SGEB) determines the acceptability of the design analyses, 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 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 through 3.7.4, 3.8.4, and 3.8.5. The Equipment Qualification Branch (EQB) reviews the seismic and environmental qualification of components under SRP Sections 3.10 and 3.11. The Mechanical Engineering Branch (MEB) determines that the components, piping, and supports are designed in accordance with applicable codes and standards as part of its primary review
