nch (EELB) will verify the 20 adequacy of the design, installation, inspection, and testing of all electrical systems required for proper operation as part of its primary review responsibility for SRP Section 8.3.1. F. The Hydrologic and Geotechnical Engineering Branch (HGEB)Civil Engineering and Geosciences Branch (ECGB) verifies the ultimate heat sink water levels, meteorological 21 and natural phenomena criteria (including ice effects), and transient analysis of the 22 cooling water inventory as part of its primary review responsibility for SRP Section 2.4. The review for fire protection is coordinated and performed by the Chemical Engineering Branch as part of its primary review responsibility for SRP Section 9.5.1.23 G. The review for technical specifications is coordinated and performed by the Licensing Guidance BranchTechnical Specifications Branch (TSB) as part of its primary review 24 responsibility for SRP Section 16.0. H. The review for quality assurance is coordinated and performed by the Quality Assurance BranchQuality Assurance and Maintenance Branch (HQMB) as part of its primary 25 review responsibility for SRP Chapter 17. DRAFT Rev. 3 - April 1996 9.2.5-4 In addition, ASB will coordinate other branch evaluations that interface with the overall review of the system as follows: The Reactor Systems Branch (RSB) will confirm the heat loads transmitted to the UHS from the reactor coolant and emergency core cooling systems as part of its primary review responsibility for SRP Section 6.3. The Structural Engineering Branch (SEB) will determine 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 the 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
