is not vibration free the panel shall be equipped with vibration mounts. 5. General Design Criterion 18, as related to the testability of the onsite a-c power system, and the guidelines of Regulatory Guide 1.118 (see also IEEE 338), as related to the capability for testing the onsite a-c power system. 6. The design requirements for an onsite a-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 the a-c power system and the guidelines of Regulatory Guide 1.63 (see also IMEE 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 a-c power systems. Branch Technical Positi6ns and industry standards that provide information, recommendations and guidance and-in general describe a basis acceptable-to the staff that way be used to implement the requirements of General Design Criteria 2, 4, 5, 17, 18, and 50 are identified in SRP Section 8.1, Table 8.1 and Appendix 8-A. In addition, Task Action Plan items II.E.3.1 and II.G.1 of NUREG's 0737 and 0718 are also implemented to meet these regulations. III. REVIEW PROCEDURES The primary objective in the review of the a-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
