anical survivability of Category I instrumentation and electrical equipment (including raceways, switchgear, control room boards, and instrument racks and panels) in the event of a seismic occurrence. Electrical operability is reviewed by EQB as described above.43 The Chemical Engineering Branch (CMEB) examines the fire detection and fire protection systems for the ac power system and its supporting auxiliary system components to assure that adverse effects of fire are minimized as part of its primary review responsibility for SRP Section 9.5.1. This includes the adequacy of protection provided redundant safe shutdown circuits to determine that a single design basis fire will not disable both redundant circuits.44 The reviews for technical specifications and quality assurance including periodic testing are coordinated and performed by the Licensing Guidance Branch and Quality Assurance Branch as part of their primary review responsibility for SRP Sections 16.0 and 17.0 respectively.45 13. The Technical Specifications Branch (TSB) coordinates and performs reviews of technical specifications as part of its primary review responsibility for SRP Section 16.0.46 14. The Human Factors Assessment Branch (HHFB), as part of its primary review responsibility for SRP Sections 13.5.1.1 and 13.5.2.1, reviews the adequacy of administrative, maintenance, testing, and operating procedure programs.47 8.3.1-7 DRAFT Rev. 3 - April 1996 For those areas of review identified above as being reviewed as part of the review under other SRP sections primary review responsibility of other branches, the acceptance criteria necessary for the review and their methods of application are contained in the referenced SRP sections of the corresponding primary branch.48 II. ACCEPTANCE CRITERIA In general, the onsite ac power system is acceptable when it can be concluded that this system has the required redundancy, meets the single failure criterion, is protected from the effects of postulated
