as based on the applicant meeting the positions of Regulatory Guides 1.6, 1.9, 1.32, 1.75, and 1108, and NUREG/CR 0660. 5. The 'applicant has met the requirements of GOC 18, "Inspection And Testing of Electric Power Systems", with respect to the onsite Class 1E a-c power system. The a-c power system is designed to be testable during operation of the nuclear power generating station as well as during those intervals when the station is shutdown. This meets the positions of Regulatory Guide 1.118. 6. The applicant has met the requirements of GDC 50, "Containment Design Bases", with respect to penetrations containing circuits of the safety and non-safety a-c power system. Containment electric penetrations have been designed to accommodate, without exceeding their design leakage rate, the calculated pressure and temperature conditions resulting from any loss-of-coolant accident concurrent with the maximum short-circuit current versus time condition that could occur given single random failures of circuit overload protective devices. This meets the positions of Regulatory Guide 1.63. V. IMPLEMENTATION The following is intended to provide guidance to applicants and licensees regarding the NRC staff's plans for using this SRP section. Except in those cases in which the applicant proposes an acceptable alternative method for complying with specified portions of the Commission's regulations, the method described herein will be used by the staff in its evaluation of conformance with Commission regulations. Implementation schedules.for conformance to parts of the method discussed herein are contained in the referenced regulatory guides and NUREG. VI. REFERENCES 1.
