ing of all electrical systems (sensing, control, and power) required to provide the safety-related func- tions of the CVCS as part of their primary review responsibility for SRP Sections 7.1, 7.6, and Appendix 7A for ICSB and SRP Section 8.3.1 for PSB. The Structural Engineering Branch (SEB) determines the acceptability of the design analysis, 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, 3.4.2, 3.5.3, 3.7.1, 3.7.2, 3.7.3, 3.8.4, and 3.8.5. The Mechanical Engineering Branch (MEB) determines the acceptability of the seismic and quality group classifications for systems components as part of its pri- mary review responsibility for SRP Sections 3.2.1 and 3.2.2. The MEB also determines that the piping, components, and structures are designed 9.3.4-2 Rev. 2 - July 1981 in accordance with applicable code's and standards as part of its primary review responsibility for SRP Sections 3.9.1,' 3.9.2, and 3.9.3. The Auxiliary Systems Branch (ASB), as part .of its primary review respon- sibility for SRP Section 3.6.1, evaluates. the effect of high- and moderate- energy CVCS system piping failures outside containment to assure that other safety-related systems will not be made inoperable. The ASB also evaluates the capability of internally generated missiles both inside and outside primary containment as part of its primary review responsibility for SRP Sections 3.5.1.1 and 3.5.1.2. The.ASB also evaluates the capability of safety-related systems to withstand the effects of missiles generated by natural phenomena or externally generated missiles as part of its pri- mary review responsibility to SRP Sections 3.5.1.4 and 3.5.2. The ASB also evaluates the capability of the CVCS to
