vant requirements of the 25 following regulations: A. General Design Criterion (GDC) 10 (Reference 2) (GDC 10), as it relates to the reactor 26 coolant system being designed with appropriate margin to assureensure that specified 27 acceptable fuel design limits are not exceeded during normal operations, including anticipated operational occurrences. B. General Design Criterion 15 (GDC 15) (Reference 3), as it relates to the reactor coolant 28 system and its associated auxiliaries being designed with appropriate margin to assureensure that the pressure boundary will not be breached during normal operations, 29 including anticipated operational occurrences. C. General Design Criterion 26 (GDC 26) (Reference 4), as it relates to the reactivity 30 control system to provide adequate control of reactivity changes during manual operations and anticipated transients to assureensure that the acceptable fuel design 31 limits are not exceeded. D. TMI Action Plan requirements items No's. II.K.2.8, II.K.3.1, II.K.3.5, II.K.3.16 (10 32 CFR 50.34(f)(1)(vi)), II.K.3.25 (10 CFR 50.34(f)(1)(iii)), and II.K.3.40 of 33 NUREGs-0718 and -0737 (Refs. 11 and 12).34 E. Acceptance criteria for implementation of TMI Action Plan item II.K.3.5 relative to a reactor coolant pump trip after the inadvertent opening of a PWR pressurizer pressure relief valve (a small-break loss-of-coolant accident) are contained in Generic Letters 85- 12, 86-05, and 86-06.35 The general objective in the review of inadvertent primary pressure relief valve opening events is to confirm that the following criteria are met: 1. The consequences of the transient are less severe than the consequences of another transient that results in a decrease of reactor coolant inventory and has the same anticipated frequency classification. The term "moderate frequency" is used in this SRP section in the same sense as in the * description of design and plant process conditions in References 7 and 8. DRAFT Rev. 2 - April 1996 15.6.1-4
