ign Criterion 5, as related to the sharing of structures, systems, and components of the a-c power system,-and the following guidelines: a. Regulatory-Guide 1.32 (see also IEEE 308), as related to the sharing of structures, systems, and components of the a-c power system, b. Regulatory Guie 1.81, as related to the sharing of structures, systems, and components of the a-c power system, positions C.2 and C.3. 8.3.1-5 Rev. 2 - July 1981 4. General Design Criterion 17, as related to the-onsite a-c power system's (a) capacity and capability to permit functioning of structures, systems, and components important to safety Cb) the independence, redundancy, and testability to perform It s safety function assuming a single failure, and (c) provisions to minimize the probability 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 the loss of power from the transmission network. Acceptance is based on meeting the following specific guidelines: a. Regulatory Guide 1.6, as related to the independence of the onsite a-c power system, positions D.1, D.2, D.4, and D.5. b. Regulatory Guide 1.9 (see also IEEE 387). c. Rejulatory Guide 1.32 (see also IEEE 308) as related to design cr teria for onsite a-c power systems; d. Regulatory Guide 1.75 (see also IEEE 304) as related to the onsite a-c power system. e. Regulatory Guide 1.108 as related to the testability of the onsite a-c power system. f. NUREG/CR 0660, as related to the following recommendations: (1) The diesel generator sets shall be capable of operation at less than full load for extended periods of. time without degradation of performance or reliability. With offsite power available, no load operation of the diesel generators will occur following a safety injection signal. Etended no load operation of this equipment shall be minimized. Operating procedures shall be provided that limit extended no load operation of the diesel
