g con- ditions. e. Provision of proper instruments and testing systems to permit opera- tional testing of the system. f. Provisions to assure that normal protective interlocks do not pre- clude engine operation during emergency conditions. 4. The PSB will determine the adequacy of design installation, inspection, and testing of all electrical components (sensing, control, and power) required for proper operation of the system, including interlocks. In the review of the emergency diesel engine cooling water system, the PSB will coordinate other branches evaluations that interface with the overall review of the system as follows: The Structural Engineering Branch (SEB) determines the acceptability of the design analyses, procedures, and criteria used to establish the ability of the 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. The Mechanical Engineering Branch (MEB) determines that components, 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. The MEB also determines the acceptability of the seismic and quality group classifications for system components as part of its primary review responsibility for SRP Sections 3.2.1 and 3.2.2. The Materials Engineering Branch verifies, upon request of PSB, the compatibility of the materials of construction with service conditions. The Auxiliary Systems Branch (ASB) determines that the EDECWS is in accordance with Branch Technical Positions ASB 3-1 and MEB 3-1 for cracks and breaks in high-energy and moderate-energy piping systems outside containment as part of its primary review responsibility for SRP Section 3.6.1.
