ll 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 of other branches, the acceptance criteria necessary for the review and their methods of application are contained in the referenced SRP section of the corresponding primary branch. 8.2-3 Rev. 3 - July 1983 II. ACCEPTANCE CRITERIA In general, the preferred power system is acceptable when it can be concluded that two separate circuits from the transmission network to the onsite Class 1E power distribution system are provided adequate physical and electrical separa- tion exists, and the system has the capacity and capability to supply power to all safety loads and other required equipment. Table 8-1 lists General Design Criteria, regulatory guides, and staff technical positions utilized as the bases for arriving at this conclusion. The PSB acceptance criteria for the integrated design of the offsite power system are based on meeting the relevant requirements and guidelines of the following: 1. General Design Criterion 5 as it relates to sharing of structures, systems, and components of the preferred power systems; and guidelines of Regulatory Guide 1.32 as related to its endorsement of Section 8.1 of IEEE Standard 308-1974, relating to sharing of structures, systems, and components of the preferred offsite power system. 2. General Design Criterion 17 as it relates to the preferred power system's (i) capacity and capability to permit functioning of structures, systems, and components important to safety, (ii) provisions to minimize the prob- ability of losing electric power from any of the remaining supplies as a result of, or coincident with, the loss of power generated by the nuclear power unit or loss of power from the onsite electric power supplies, (iii) physical independence, (iv) availability, and the guidelines of Regulatory Guide 1.32 (see also IEEE 308-1974) as
