nstabilities resulting from (N-1) loop and other operational circumstances, the reviewer should use the guidance found in the requirements of SRP Section 15.9. The reviewer should also verify that the applicant has addressed the possibility for jet pump vibration during (N-1) loop operation. For advanced BWR applicants proposing to operate with less than the maximum number of 10 reactor internal pumps (RIPs), the reviewer confirms that continued plant operation with fewer than 10 RIPs in operation including any reactor power level restrictions, is compatible with the plant safety analyses and flow test results do not demonstrate significant differences in core flow patterns. 11. 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. 12. The reviewer examines the calculation of hydraulic loads for normal operations, including AOOs, to ensure that they are properly estimated for the 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). The reviewer will also provide calculations for design-basis accident conditions. The review of the adequacy of components and structures under design-basis accident loads is performed under SRP Sections 3.9.3 and 3.96. The review to determine that a coolable core geometry is maintained is performed under SRP Section 4.2. 13. The reviewer should ensure that an adequate loose parts monitoring system is provided. For COL applications, the design criteria for the system and the types, locations, and methods of mounting for all intended sensors should be reviewed. The reviewer should compare the design to Regulatory Guide 1.133, equipment used, and application experience on comparable plants. OL and COL reviews consist of a more complete description of the loose parts
