nt pressure boundary are not exceeded during an AOO. 5. GDC 26, as it relates to the reliable control of reactivity changes to ensure that SAFDLs are not exceeded, including AOOs. This is accomplished by assuring that appropriate margin for malfunctions, such as stuck rods, are accounted for. 6. TMI Action Plan item II.K.2.19 of NUREG-073 and 10 CFR 50.34(f)(1)(ii)1 and 10 CFR 50.34(f)(2)(xii) as they relate to the performance requirements of the auxiliary feedwater system for the loss of normal feedwater flow event. SRP Acceptance Criteria Specific SRP acceptance criteria acceptable to meet the relevant requirements of the NRC’s regulations identified above are as follows for the review described in this SRP section. The SRP is not a substitute for the NRC’s regulations, and compliance with it is not required. However, an applicant is required to identify differences between the design features, analytical techniques, and procedural measures proposed for its facility and the SRP acceptance criteria and evaluate how the proposed alternatives to the SRP acceptance criteria provide acceptable methods of compliance with the NRC regulations. 1. The basic objective in the review of the loss of normal feedwater transient is to confirm that the following criteria are met: A. The plant responds to the loss of feedwater transient in such a way that the criteria regarding fuel damage and system pressure are met. B. There is sufficient capacity for long term decay heat removal for the plant to reach a stabilized condition. C. The plant protection systems setpoints assumed in the transient analyses are selected with adequate allowance for measurement uncertainties as delineated in Regulatory Guide 1.105. 15.2.7-5 Revision 2 - March 2007 D. The event evaluation takes into consideration single failures, operator errors, and performance of non-safety related systems that are consistent with regulatory guidelines set forth in RG 1.206. 2. Using the ANS standards as guidance,
