ers that were within the instruments’ prescribed operating ranges. The parameters used as input to the analytical model were reviewed and found to be suitably conservative and in accordance with the recommendation of Regulatory Guide 1.105. The results of the analysis of the transient showed that cladding integrity was maintained by ensuring that the minimum departure from nucleate boiling ratio (or minimum critical power ratio for a BWR) did not decrease below____and that the maximum pressure within the reactor coolant and main steam systems did not exceed 110% of their design pressures. Thus, the applicant has met the requirements of GDC 17, and 26 with respect to demonstrating that SAFDLs are not exceeded for this event. The applicant has met the positions of Regulatory Guide 1.53, SECY 77-439, SECY 94-084 and RG 1.206 as related to the single-failure criterion and Regulatory Guide 1.105 as related to instrument actuations of systems and components important to safety. For DC and COL reviews, the findings will also summarize the staff’s evaluation of requirements and restrictions (e.g., interface requirements and site parameters) and COL action items relevant to this SRP section. 15.2.7-11 Revision 2 - March 2007 V. IMPLEMENTATION The staff will use this SRP section in performing safety evaluations of DC applications and license applications submitted by applicants pursuant to 10 CFR Part 50 or 10 CFR Part 52. Except when the applicant proposes an acceptable alternative method for complying with specified portions of the Commission’s regulations, the staff will use the method described herein to evaluate conformance with Commission regulations. The provisions of this SRP section apply to reviews of applications submitted six months or more after the date of issuance of this SRP section, unless superseded by a later revision. The following is intended to provide guidance to applicants and licensees regarding the NRC staff's plans for using this SRP section.
