VS performance. 3. The ASB also performs the following reviews under the SRP sections indicated: a. 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. d. Review of high- and moderate-energy pipe breaks is performed under SRP Section 3.6.1. The ASB will coordinate evaluations performed by other branches that interface with the overall evaluation of the system as follows: The Instrumentation and Control Systems Branch (ICSB) and Power Systems Branch (PSB) determine the adequacy of the design, installation, inspection, and test- ing of all essential electrical components (sensing, control, and power) required for proper operation as part of their primary review responsibility for SRP Sections 7.3 and 8.3.1 respectively. 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 responsi- bility for SRP Sections 3.2.1 and 3.2.2. 9.4.1-2 Rev. 2 - July 1981 MEB also reviews the adequacy of the inservice testing
