ee 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. The design requirements for an onsite d-c power supply for systems covered by General Design Criteria 33, 34, 38, 41 and 44 are encompassed in General Design Criterion 17. 7. General Design Criterion 50, as related to the design of containment electrical penetrations containing circuits of safety-related and nonsafety-related d-c power systems and guidelines of Regulatory Guide 1.63 (see also IEEE 317), as related to the capability of the electric penetration assemblies to withstand, without loss of mechanical integrity, the maximum possible fault current versus time condition that could occur given single random failure of circuit overload protective devices located in circuits of the onsite Class lE and non-Class HE d-c power systems. Branch Technical Positions and Regulatory Guides that provide information, recommendations and guidance and in general describe a basis acceptable to the staff that may be used to implement the requirements of General Design 8.3.2-5 Rev. .2 - July 1981 Criteria 2, 4, 5, 17, 18, and 50 are identified in SRP Section 8.1, Table 8.1 and Appendix 8-A. III. REVIEW PROCEDURES The primary objective in the review of the d-c power system is to determine that this system satisfies the acceptance criteria stated in subsection II and will perform its design functions during plant normal operation, anticipated operational occurrences, and accident conditions. In the CP review, the descriptive information, including the design bases and their relation to the acceptance criteria, preliminary analyses, electrical single line diagrams, functional logic diagrams, preliminary functional piping and instrumentation diagrams (P&IDs), and preliminary physical arrangement drawings are examined to determine that there is reasonable assurance that the final
