applicant to show that the core burnup selected yields the minimum margins. CPS is consulted regarding the values of the reactivity parameters used in the applicant's analysis. 15.1.1-5 Rev. 1 - July 1981 The results of the analysis are reviewed and compared to the acceptance criteria presented in subsection II of this SRP section regarding the maximum pressure in the reactor coolant and main steam systems. The variations with time during the transient of the neutron power, heat fluxes (average and maximum), reactor coolant system pressure, minimum DNBR (PWR) or CPR (BWR); core and recirculation loop coolant flow rates (BWR), coolant conditions (inlet temperature, core average temperature (PWR), core average steam volume fraction (BWR), average exit and hot channel exit temperatures, and steam fractions), steamline pressure, containment pressure, pressure relief valve flow rate, and flow rate from the reactor coolant system to the containment system (if applicable) are reviewed. The values of the more important of these parameters,. as listed in subsection I of this SRP section, are compared to those predicted for other similar plants to see that they are within the range expected. The NRC has undertaken a program to reduce the sensitivity of B&W plants to feedwater transients (Items II.E.5.1 and II.E.5.2, NUREG-0660 and 0718). When this program is complete, the RSB reviewer, with the aid of other branches as appropriate, should incorporate the program results into the review of this SRP section. IV. EVALUATION FINDINGS The reviewer verifies that the SAR contains sufficient information and his review supports the following kinds of statements and conclusions, which should be included in the staff's safety evaluation report: A number of plant transients can result in an unplanned increase in heat removal by the secondary system. Those that might be expected to occur with moderate frequency can be.caused by feedwater system or pressure regulator malfunctions or the
