ructures, systems and components of the d-c power system being capable of withstanding the effects of missiles and environmental conditions associated with normal operation and postulated accidents as established in Chapter 3 of the SAR and reviews by ASB, RSB and EQB as part of their primary-review Responsibility. 8.3.2-4 Rev. 2 - July 1981 3. General Design Criterion 5, as related to the sharing of structures, systems, and components of the d-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 d-c power system, position C.2.a. b. Regulatory Guide 1.81, as related to the sharing of structures, systems, and components of the d-c power system, position C.1. 4. General Design Criteron 17, as related to the onsite d-c power system's (a) capacity and capability to permit functioning of.structures, systems, and components important to safety, (b) the independence and redundancy to perform its safety function assuming a single failure, and (c) provi- sions to minimize the probability of losing electric power from any of the remaining s uplies 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 onsite d-c power system, positions D.1, D.3, and D.4.. b. Regulatory Guide 1.32 (see also IEEE 308), as related to the onSite d-c power system. c. Regulatory Guide 1.75 (see also IEEE 384), as related to the onsite d-c power system. 5. General Design Criterion 18, as related to the testability of the onsite d-c power system, and the following guidelines: a. Regulatory Guide 1.32 (see also IEEE 308), as related to test capability of the onsite d-c power system. b. Regulatory Guide 1.118 (see also IEEE 378), as related to the capability for testing the onsite d-c power system. 6.
