ated to the sharing of 57 structures, systems, and components of the ac power system. b. Regulatory Guide 1.81, as related to the sharing of structures, systems, and components of the ac power system, positions C.2 and C.3. 4. General Design Criterion 17 (GDC 17), as related to the onsite ac power system's 58 (a) capacity and capability to permit functioning of structures, systems, and components important to safety; (b) the independence, redundancy, and testability to perform its 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 DRAFT Rev. 3 - April 1996 8.3.1-8 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 ac power system, positions D.1, D.2, D.4, and D.5. b. Regulatory Guide 1.9 (see also IEEE Std 387). c. Regulatory Guide 1.32 (see also IEEE Std 308), as related to design criteria for onsite ac power systems. d. Regulatory Guide 1.75 (see also IEEE Std 304384), as related to the onsite 59 ac power system. e. Regulatory Guide 1.108 as related to the testability of the onsite ac power system. Regulatory Guide 1.153 (see also IEEE Std 603), as related to 60 criteria for electrical portions of safety-related systems.61 f. Regulatory Guide 1.155, as related to consideration of onsite emergency source reliability in evaluating station blackout issues and establishing an acceptable reliability program for onsite emergency sources.62 fg. NUREG/CR-0660, as related to the following recommendations: 63 (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
