r monitoring the heat transfer capability of safety- related heat exchangers cooled by service water under SRP Section 9.2.1. If such tests indicate degradation in heat transfer capability that cannot be remedied by maintenance of the service water system, closed loop cooling systems such as the EDECWS reviewed under SRP 9.5.5 should be included in the scope of the inspection and maintenance program for service water systems, also reviewed under SRP 9.2.1.11 3. The SPLB reviews for the EDECWS to determine the adequacy of fire protection provisions are coordinated and performed by the Chemical Engineering Branchas part of theirits primary review responsibility for SRP Section 9.5.1.12 In addition,the review of the emergency diesel engine cooling water system, the PSBSPLB 13 14 will coordinate other branches evaluations that interface with the overall review of the system as follows: 1. Structural Engineering Branch (SEB)Civil Engineering and Geosciences Branch (ECGB) determines the acceptability of the design analyses, procedures, and criteria 15 used to establish the ability of Category I facility structures housing the system and supporting systems to withstand the effects of natural phenomena such as a 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. 2. The Mechanical Engineering Branch (MEB)(EMEB) determines that components, 16 piping, and structures are designed in accordance with applicable codes and standards as part of its primary review responsibility for SRP Sections 3.9.1 through 3.9.3. 3. The (MEB)EMEB also determines the acceptability of the seismic and quality group 17 classifications for system components as part of its primary review responsibility for SRP Sections 3.2.1 and 3.2.2. 4. The Materials Engineering BranchMaterials and Chemical Engineering Branch (EMCB) verifies, upon request of
