Content:
n as to transients expected to occur with moderate frequency and to result in the loss of all power to the station auxiliaries is acceptable and meets the relevant requirements of GDCs 10, 13, 15, and 26 and the applicable TMI Action Plan items. This conclusion is based on the following findings: 1. The applicant meets the requirements of GDCs 10 and 26 by demonstrating that resultant fuel integrity is maintained because the specified acceptable fuel design limits were not exceeded for the event. 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. 15.2.6-9 Revision 2 - Month 2007 3. The applicant meet GDC 15 requirements by demonstrating that the reactor coolant pressure boundary limits were not exceeded by this event and that resultant leakage is within acceptable limits. This requirements is met because the maximum pressure within the reactor coolant and main steam systems did 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 specified acceptable fuel design limits were not exceeded. 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. 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
