ceeded during any condition of normal operation, including the effects of anticipated operational occurrences. 2 GDC 13, which requires, in part that the effect of instrumentation shall be provided to monitor variables and systems over their anticipated ranges for anticipated operational occurrences to assure adequate safety. Appropriate controls shall be provided to maintain these variables and systems within prescribed operating ranges. 3. GDC 15, which requires that the reactor coolant system and its associated auxiliary control and protection systems be designed with sufficient margin to assure that the design conditions of the reactor coolant pressure boundary are not exceeded during any condition of normal operations, including anticipated operational occurrences. 4. GDC 26, which requires, in part, the reliable control of reactivity changes to assure that specified acceptable fuel design limits are not exceeded under conditions of normal operation, including anticipated operational occurrences, with appropriate margin for malfunctions, such as stuck rods. 5. For plants with licensing bases that incorporate RG 1.70, ANS 51.1 (for PWRs), or ANSI/ANS-52.1-1978 (for BWRs), there are acceptance criteria, in SRP 15.0, “Condition II” events, or events of moderate frequency, “Condition III events, or infrequent events, and “Condition IV” events, or postulated accidents of low probability. Acceptance criteria are also defined for Condition II, III, and IV events. Regulatory Issue Summary (RIS) 2005-29, which relates to the escalation of a Condition II event into a Condition III or IV event, is also applicable to these plants. 15.5.1-15.5.2-4 Revision 2 - March 2007 The basic objectives in reviewing the events leading to an increase in reactor coolant inventory are: 1. To identify which of the AOOs leading to an RCS inventory increase are the most limiting. 2. To verify that, for the most limiting transients, the plant responds to the RCS inventory increase
