iew of the environmental qualification of components is performed under SRP Section 3.11.19 7. Review of the Main Steam Isolation Valve Leakage Control System is performed under SRP Section 6.7. 20 8. Review of fire protection is performed under SRP Section 9.5.1.21 In the review of the main steam supply system, the ASB and PSBIn addition, the SPLB will 22 coordinate other branches' evaluations that interface with the overall review of the system as follows: 1. The Reactor Systems Branch (SRXB)(RSB) identifies essential components associated 23 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 5.2.2. 24 DRAFT Rev. 4 - April 1996 10.3-4 2. The Structural and GeotechnicalCivil Engineering and Geosciences Branch (ECGB)(SGEB) determines the acceptability of the design analyses, procedures, and 25 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. 3. The Equipment Qualification Branch (EQB) reviews the seismic and environmental qualification of components under SRP Sections 3.10 and 3.11. The Mechanical 26 Engineering Branch (EMEB) reviews the seismic qualification of components as part of its primary review responsibility for SRP Section 3.10.27 4. The EMEBMechanical Engineering Branch (MEB) determines that the components, 28 piping, and supports are designed in accordance with applicable codes and standards as part of its
