Revision 2 - March 2007 the reactor coolant and main steam systems. The applicant analyzed this transient using a mathematical model reviewed and accepted by the staff. The values of the input parameters to this model were reviewed and found suitably conservative. The staff concludes that the plant design for transients expected to occur during plant life and result in a loss or decrease in forced reactor coolant flow is acceptable and meets the requirements of GDCs 10, 13, 15, 17, 20 and 26. This conclusion is based on the following findings: 1. The applicant meets the requirements of GDCs 10, 17, 20, and 26 by demonstrating that SAFDLs are not exceeded in this event. This requirement is met as the results of the analysis show that the thermal margin limits (minimum DNBR for PWRs, MCPR for BWRs) are satisfied as indicated by SRP Section 4.4. 2. The applicant meets GDC 13 requirements by demonstrating that all credited instrumentation was available, and that actuations of protection systems, automatic and manual, occurred at values of monitored parameters that were within the instruments’ prescribed operating ranges. 3. The applicant meets the requirements of GDCs 15 and 17 by demonstrating that the reactor coolant pressure boundary limits are exceeded in this event. This requirement is met as the analysis shows that the maximum pressure of the reactor coolant and main steam systems does not exceed 110 percent of the design pressure. 4. The applicant meets GDC 26 requirements for the capability of the reactivity control system to control reactivity adequately during this event with appropriate margin for stuck rods because the SAFDLs are not exceeded. 5. The applicant meets the positions of RG 1.53, SECY 77-439, SECY 94-084, and RG 1.206 on the single-failure criterion and RG 1.105 on instrument actuations of safety-related SSCs. For DC and COL reviews, the findings will also summarize the staff’s evaluation of requirements and restrictions (e.g., interface
