ation including any reactor power level restrictions, are compatible with the plant safety analyses, and flow test results demonstrate there are no significant differences in core flow patterns.60 The reviewer ensures that adequate account is taken of the effect of crud in the primary coolant system, such as in the calculation of CHF in the core, heat transfer in the steam generators, and pressure drop throughout the RCS. The reviewer is to examine the calculation of hydraulic loads for normal operations, including anticipated transients operational occurrences, to ensure they are properly estimated for the 61 worst cases. Worst case hydraulic loads for normal operations are to be provided for use in the analysis of lifting force of the fuel (SRP Section 4.2). CPBSRXB will also provide 62 consultation to RSB upon request, regarding calculations for postulated design-basis accident 63 64 conditions. The EMEB reviews the adequacy of components and structures under design- 65 basis accident loads (SRP Section 3.9.2) and CPBSRXB determines that a coolable core 66 67 geometry is maintained (SRP Section 4.2). The reviewer should ensure that an adequate loose parts monitoring system is provided. At the CP level, the design criteria for the system and the types, locations, and methods of mounting all DRAFT Rev. 2 - April 1996 4.4-10 intended sensors should be reviewed. The reviewer should compare the design to Regulatory Guide 1.331.133 and to equipment used and application experience on comparable plants. 68 At the OL level; a more complete description of the loose parts monitoring system including 69 sensitivity specifications and operating procedures should be reviewed. The reviewer should ensure that operating procedures and training provisions are adequate to fully utilize the system potential for loose parts detection. The Operator Licensing (OLB)HHFB will provide 70 consultation on staff training in accordance with the SRP Section 13.2.1 . 71 72 The reviewer should
