SRP sections indicated:19 1. The review for Fire Protection is coordinated and performed by the Chemical Engineering BranchSPLB as part of theirits primary review responsibility for SRP 20 21 Section 9.5.1. 2. The Equipment Qualification Branch (EQB)SPLB reviews the environmental 22 qualification of mechanical and electrical equipment as part of theirits primary review 23 responsibility for SRP Section 3.11. Coordinated reviews are performed by other branches and the results used by the ASB to complete the overall evaluation of the system. The coordinated reviews are as follows: In addition, the SPLB will coordinate other branches' evaluations that interface with the overall review of the system as follows:24 1. The RSBSRXB identifies any functional interfaces between essential components of the 25 reactor coolant or emergency core cooling systems and the AFWS that are required for operation during normal operations or accident conditions. The RSBSRXB establishes 26 postaccident heat loads and the associated time intervals available for cooling various components. The SRXB also reviews the performance of the AFWS relative to ATWS events as part of its review responsibilities for SRP Section 15.8.27 2. The StructuralCivil Engineering and Geosciences Branch (SEB)(ECGB) determines the 28 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 ECGB also verifies that inservice inspection requirements are met for system components as part of its primary review responsibility for SRP Section 6.6.29 3. The Mechanical Engineering Branch (EMEB) determines that the components piping 30 and structures
