e preferred power system. The Instrumentation and Control Systems Branch (ICSB) 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 responsi- bility for SRP Sections 7.2 through 7.7. The ICSB also verifies, on request, the adequacy of the preferred power system instrumentation and controls. The reviews for technical specifications and quality assurance including periodic testing, are coordinated and performed by the Standardization and Special Projects Branch and Quality Assurance Branch as part of their primary' review responsibility for SRP Sections 16.0 and 17.0, respectively. The Containment Systems Branch (CSB) determines those system components requir- ing 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 6.2.2, 6.2.4, and 6.2.5. The Effluent Treatment Systems Branch (ETSB) determines those system components requiring electric power as a function of time for each mode of reactor opera- tion 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 and test programs as part of its primary review responsibility for SRP Section 14.0. The Chemical Engineering Branch (CMEB) examines the fire detection and fire fighting systems in the preferred power system areas 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 power circuits to determine that a single design basis fire will not disable all onsite and offsite power supply circuits to the onsite distribution system. For those areas of review identified above as being reviewed as part of the primary review responsibility
