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 3.7.4, 3.8.4, and 3.8.5. The Materials Engineering Branch (MTEB) verifies the inservice inspection requirements are met for system components and the compatibility of the materials of construction with the service conditions as part of its primary review responsibility for SRP Section 6.1.1. The Instrumentation and Control Systems Branch (ICSB) and Power Systems Branch (PSB) will verify the adequacy of the design, installation, inspection, and testing of all electrical systems (sensing, control, and power) required for proper operation as part of the primary review responsibilities for SRP Section 7.1 and Appendix 7-A for ICSB and SRP Section 8.3.1 for PSB. The Hydrologic and Geotechnical Engineering Branch (HGEB) verifies the ultimate heat sink water levels, meteorological and natural phenomena criteria, and transient analysis of the cooling water inventory as part of its primary review responsibility for SRP Section 2.4. The review for fire protection, technical specifications, and quality assurance are coordinated and performed by the Chemical Engineering Branch, Licensing Guidance Branch, and Quality Assurance Branch as part of their primary review responsibility for SRP Sections 9.5.1, 16.0, and 17.0, respectively.26 For those areas of review identified above as being reviewed as part of the primary review responsibility of other branches, the acceptance criteria and their methods of application are contained in the referenced SRP sections corresponding to those branches.27 II. ACCEPTANCE CRITERIA Acceptability of the design of the ultimate heat sink, as described in the applicant's Safety Analysis Report (SAR), including related sections of Chapters 2 and 3 of the SAR, is based on 28 specific general design criteria and regulatory guides and on independent
