ed display instrumentation and other instrumentation systems required for safety as part of its primary review responsibility for SRP Sections-7.5 and 7.6. The Effluent Treatment Systems Branch (ETSB) determines those system components requiring electric power as a function of time for each mode of reactor operation and accident condition as part of its primary review responsibility for SRP Section 6.5.1. The Procedures and Test Review Branch (PTRB) determines the acceptability of the preoperational and initial startup tests and programs as part of its primary review responsi- bility for SRP Section 14.0. The Mechanical Engineering Branch (MEB) reviews as part of its review responsibility for SRP Sec- tion 3.11 the criteria.for seismic qualification and the test and analysis procedures and methods to ensure the mechanical surviv- ability 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. The Chemical Engineering Branch (CMEB) examines the fire detection and fire protection systems for the a-c power- system and its supporting 8.3.1-4 Rev. 2 - July 1981 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. 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. For those areas of review identified above as being reviewed as part of the primary review responsibility of other branches, the acceptance criteria
