Content:
that the analysis of a transient resulting in an unplanned increase in heat removal by the secondary system due to an increase in reactor coolant inventory is acceptable and meets the requirements of General Design Criteria 10, 15, and 26. This conclusion is based on the following: 1. In meeting GDC 10, 15 and 26 as indicated below we have determined that the applicant's analysis was performed using a mathematical model that had been previously reviewed and found acceptable by the staff. The parameters used as input to this model were reviewed and found to be suitably conservative. In addition, we have further determined that the positions of Regulatory Guide 1.53 for the single-failure criterion and Regulatory Guide 1.105 for instruments have also been satisfied. 2. The applicant has met the requirements of GDC 10 and 26 with respect to demonstrating that resultant fuel damage is maintained since the speci- fied acceptable fuel design limits were not exceeded for this event. 3. The applicant has met the requirements of GDC 15 with respect to demonstrat- ing that the reactor coolant pressure boundary limits have not been exceeded by this event and that resultant leakage will be within acceptable limits. This requirement has been met since the maximum pressure within the reactor coolant and main steam systems did not exceed 110% of the design pressures. "The SER draft should present one statement for all similar transients.
