acceptance criteria of 10 CFR Part 50, §50.46, and Appendix K to demonstrate that their ECCS designs for peak cladding temperature, maximum calculated cladding oxidation, maximum hydrogen generation, coolable core geometry, and long-term cooling are in accordance with the acceptable evaluation model. In addition, the applicant has met the requirements of the following Task Action Plan items: 6.3-11 Rev. 2 - April 1984 (1) Meeting Task Action Plan item II.B.8 of NUREG-0718 (Ref. 14) which involves description by the applicants of the degree to which the designs conform to the proposed interim rule on degraded core accidents (CPs only). (2) Meeting Task Action Plan item II.D.1.1 of NUREG-0737 (Ref. 15) and NUREG-0718 (Ref. 14) which involves primary coolant sources outside of containment (CPs and OLs). (3) Meeting Task Action Plan item II.E.2.1 of NUREG-0660 (Ref. 16) which involves reliance on ECCS. (4) Meeting Task Action Plan item Il.K.3(10) of NUREG-0660 which involves applicant's proposal to limit anticipatory trip to high power for selected plants. (5) Meeting Task Action Plan item II.K.3(15) of NUREG-0660 which involves isolation of HPCI and RCIC for BWR plants. (6) Meeting Task Action Plan item II.K.3(18) of NUREG-0660 which involves ECCS outages for all plants. (7) Meeting Task Action Plan item II.K.3(21) of NUREG-0660 which involves restart of LPCS and LPCI for BWR plants. (8) Meeting Task Action Plan item II.K.3(3a) of NUREG-0660 which involves evaluation of effects of water slugs in piping caused by HPI and CFT flows in B&W plants. 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.
