al environments that exceed the equipment' s design parameters such as temperature and humidity, (3) the effects of environments caused by loss of non-Class 1E heating and ventilation systems, (4) the effects of seismic shaking, and (5) the effects of normal design environments on redundant safety-related electrical equipment that do not have diversity of design such as redundant components manufactured and designed by the same supplier.34 8. The Reactor Systems Branch (RSBSRXB) determines those system components 35 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 Sections 4.6, 5.4.6, 5.4.7, 5.4.12, and 6.3, and 9.3.5.36 9. The Instrumentation and Controls Systems Branch (ICSBHICB) determines those 37 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 Sections 7.2 through 7.7. In addition, ICSBHICB verifies the adequacy of 38 safety-related display instrumentation, alarms, and other instrumentation systems 39 (including bypass indication, status of batteries, and status of battery chargers required for safety) as part of its primary review responsibility for SRP Sections 7.5 and 7.6. 40 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 6.5.1.41 10. The Procedures and Test Review Branch (PTRB)Quality Assurance and Maintenance Branch (HQMB) determines the acceptability of the preoperational and initial startup 42 tests and programs as part of its primary review responsibility for SRP Section 14.20.43 11. The HQMB reviews the adequacy of administrative, maintenance, testing, and operating procedure programs as part of its primary review
