Mile Island (TMI)-related requirements set forth in 10 CFR 50.34(f)(1)(vi) and 10 CFR 50.34(f)(1)(iii), for DC and COL reviews, respectively.1 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. Pressure in the reactor coolant and main steam systems should be maintained below 110 percent of the design values. 2. Fuel cladding integrity is maintained if the minimum departure from nucleate boiling ratio (DNBR) remains above the 95/95 DNBR limit for PWRs and the critical power ratio (CPR) above the minimum critical power ratio safety limit for BWRs based on acceptable correlations (see SRP Section 4.4). 3. An AOO should not develop into a more serious plant condition without other faults occurring independently. Satisfaction of this criterion precludes the possibility of a more serious event during the lifetime of the plant. To meet the requirements of GDCs 10, 13, 15, and 26, the positions of Regulatory Guide (RG) 1.105, "Instrument Setpoints for Safety-Related Systems," are useful as to their impact on the plant response to the type of transient addressed in this SRP section. The most limiting plant system single failure, as defined in the "Definitions and Explanations" of 10 CFR Part 50, Appendix A, should be assumed in the analysis and should satisfy the positions of RG 1.53. The applicant's analysis of this transient should use an acceptable analytical model. If the applicant proposes
