REVIEW RESPONSIBILITIES Primary - Power Systems Electrical Engineering Branch (PSBEELB)1 Secondary - None I. AREAS OF REVIEW The PSBEELB reviews the applicant's description of the offsite power grid system with regard 2 to the interrelationships between the nuclear unit, the utility grid, and the interconnecting grids. The PSBEELB reviews the onsite power systems to assure ensure that, given a loss of the 3 4 offsite power system and a single failure in the onsite power system, sufficient power will be available for mitigating the design basis events. In addition, the EELB reviews to ensure that each unit has the capability to withstand and recover from a station blackout lasting a specified minimum duration. PSBEELB also reviews acceptance criteria that will be implemented in the 5 6 design of the above systems. II. ACCEPTANCE CRITERIA Table 8-1, "Acceptance Criteria and Guidelines for Electric Power Systems," lists the acceptance criteria currently applied by the staff to electric power systems. Implementation of these criteria in accordance with applicable guidelines of regulatory guides and branch technical positions will provide assurance that systems will perform their design safety functions when required. Detailed discussion of specific acceptance criteria presented in Table 8-1 are provided in Standard Review Plan (SRP) Sections 8.2, 8.3.1, 8.3.2, and 8.4 (proposed). Each SRP section DRAFT Rev. 3 - April 1996 8.1-2 also contains a description of the technical rationale for applying these criteria to reviews of electrical power systems.7 III. REVIEW PROCEDURES The PSBEELB reviews Section 8.1 of the SAR safety analysis report (SAR) to assure ensure 8 9 the following items are included: a brief description of the utility grid and its interconnections to other grids and to the nuclear unit; a brief general description of the onsite power system; a brief description of the Alternate AC (AAC) power source, if provided for station blackout, and the associated
