ted. CPB is consulted regarding the values of the reactivity parameters used in the applicant's analysis.35 The results of the analysis are reviewed, including the effects of the LOOP, and compared to 36 with the acceptance criteria presented in subsection II of this SRP section regarding maximum 37 pressure in the reactor coolant and main steam systems. The parameters reviewed are:38 1. The variations with time during the transient of the neutron power, 2. heat fluxes (average and maximum), 3. reactor coolant system pressure, 4. minimum DNBR (PWR) or CPR (BWR), 5. core and recirculation loop coolant flow rates (BWR), 6. coolant conditions (inlet temperature, core average temperature (PWR), core average steam volume fraction (BWR), average exit and hot channel exit temperatures, and steam fractions), 7. steamline pressure, 8. containment pressure, 9. pressure relief valve flow rate, and DRAFT Rev. 2 - April 1996 15.2.7-10 10. flow rate from the reactor coolant system to the containment system (if appli- cable). The more important of these parameters for the loss of normal feedwater transient are compared to with those predicted for other similar plants to see that they are within the range expected. 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.39 IV. EVALUATION FINDINGS The evaluation findings under this SRP section are incorporated in a statement covering all transients of moderate frequency involving an
