valuation model; alternatively, an ECCS evaluation model may be developed in conformance with and Appendix K to 10 CFR Part 50. as it relates to the ECCS being designed so that its cooling performance is in accordance with an acceptable evaluation model.48 H. TMI Action Plan item II.K.3.18 of NUREG-0737, equivalent to 10 CFR 50.34(f)(1)(vii) for applicants subject to 10 CFR 50.34(f), with respect to eliminating the need for manual actuation of the BWR ADS to assure adequate core cooling.49 I. TMI Action Plan item II.K.3.21 of NUREG-0737, equivalent to 10 CFR 50.34(f)(1)(viii) for applicants subject to 10 CFR 50.34(f), with respect to studying the design of BWR core spray and low pressure coolant injection systems to ensure that the systems will automatically restart on loss of water level, after having been manually stopped, if an initiation signal is still present.50 J. TMI Action Plan item II.K.3.28 of NUREG-0737, equivalent to 10 CFR 50.34(f)(1)(x) for applicants subject to 10 CFR 50.34(f), with respect to BWR ADS-associated equipment and instrumentation being capable of performing their intended functions during and following an accident, while taking no credit for non-safety related equipment or instrumentation, and accounting for normal expected air (or nitrogen) leakage through valves.51 K. TMI Action Plan item II.K.3.45 of NUREG-0737, equivalent to 10 CFR 50.34(f)(1)(xi) for applicants subject to 10 CFR 50.34(f), with regard to providing an evaluation of depressurization methods, other than full actuation of the ADS, that would reduce the possibility of exceeding vessel integrity limits during rapid cooldown for BWRs.52 6.3-7 DRAFT Rev. 3 - April 1996 L. TMI Action Plan item III.D.1.1 of NUREG-0737, equivalent to 10 CFR 50.34(f)(2)(xxvi) for applicants subject to 10 CFR 50.34(f), with respect to the provisions for a leakage detection and control program to minimize the leakage from those portions of the ECCS outside of the containment that contain or may
