Review of 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, and d. Review of high and moderate energy pipe breaks is performed under SRP Section 3.6.1. Should the LLHS design deviate significantly from previously accepted designs, ASB will request pertinent reviews by other branches. Input from these branches will be coordinated by the ASB and incorporated into the ASB overall system evaluation. The coordinated reviews are as follows: The Structural Engineering Branch (SEB) 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 thru 3.7.4, 3.8.4, and 3.8.5. The Mechanical Engineering Branch (MEB) determines that the 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 thru 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 MEB also reviews the adequacy of the inservice testing program of pumps and valves as part of its primary review responsibility for SRP Section 3.9.6. The Materials Engineering Branch (MTEB) verifies that inservice inspection requirements are met for system components as part of its primary review responsibility for SRP Section 6.6, and, upon request, verifies the compatibility of
