nt of such frequency because of the unique design features of ABWR instrumentation and control systems.63 For standard design certification reviews under 10 CFR Part 52, the procedures above should be followed, as modified by the procedures in SRP Section 14.3 (proposed), to verify that the design set forth in the standard safety analysis report, including inspections, tests, analysis, and acceptance criteria (ITAAC), site interface requirements and combined license action items, meet the acceptance criteria given in subsection II. SRP Section 14.3 (proposed) contains procedures for the review of certified design material (CDM) for the standard design, including the site parameters, interface criteria, and ITAAC.64 IV. EVALUATION FINDINGS The reviewer verifies that the SAR contains sufficient information and histhat the review 65 supports the following kinds of statements and conclusions, which should be included in the staff's safety evaluation report (SER): A number of plant transients can result in an increase in reactor coolant inventory. Those that might be expected to occur with moderate frequency are inadvertent operation of the emergency core cooling system, chemical and volume control system malfunction, and various BWR transients. All these postulated transients have been reviewed. It was ** found that the most limiting in regard to _______________ was the _______________ transient. The staff concludes 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, 17, 15, and 26. This conclusion is 66 based on the following: 1. In meeting GDCGeneral Design Criteria 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
