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.66 IV. EVALUATION FINDINGS The reviewer verifies that the SAR contains sufficient information and his that the review 67 supports the following kinds of statements and conclusions which should be included in the staff's safety evaluation report (SER): Several types of plant occurrences can result in an unplanned decrease in reactor coolant flow rate. The ones expected during the life of the plant are those caused by reactor coolant (or recirculation) pump trips or a flow controller malfunction. All these b postulated transients have been reviewed. It was found that the most limiting in regard to core thermal margins and pressure within the reactor coolant and main steam systems was the transient. This transient was evaluated by the applicant using a mathematical model that has been reviewed and found acceptable by the staff. The values of the parameters used as input to this model were reviewed and found to be suitably conservative. The staff concludes that the plant design with regard to transients that are expected to occur during plant life and result in a loss or decrease in forced reactor coolant flow is acceptable and meets the relevant requirements of General Design Criteria (GDC) 10, 68 15, 17, and 26. This conclusion is based on the following: 69 1. The applicant has met the requirements of GDC General Design Criteria 10, 70 17 and 26 with respect to demonstrating that the specified acceptable fuel design 71 limits are not exceeded for this event. This requirement has
