ulatory position in BTP_ d. The calculational method used by the applicant for (state) has been previously reviewed by the staff and found acceptable; the staff has reviewed the key parameters in this case and found them to be suitably conservative. e. The applicant has met the requirements of (industry standard - number and title) that has been reviewed by the staff and determined to be appropriate for this application. 2. Repeat the above discussion for each GDC listed. In addition, conformance with General Design Criterion 55, 56, and 57 regarding containment isolation is discussed in Section 6.2 of this report. Conformance 5.4.6-8 Rev. 3 - April 1984 with General Design Criterion 2 and 4 for protection against natural phenomena, environmental hazards and potential missiles is discussed in Sections 3.3 through 3.6 of this report. The RCIC and HPCS (or HPCI) systems, in conjunction with the safety/relief valves and the suppression pool cooling mode of the residual heat removal system, have been found capable of removing core decay heat following feedwater system isolation and reactor shutdown so that sufficient coolant inventory is maintained in the reactor vessel to keep the core covered and ensure cladding integrity. This capability has been found to be available even with a loss of offsite power and with a single active failure. 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, NUREGs and implemen- tation of acceptance criterion subsections II.A and II.9 is as
