ith those specified in the licensee=s SAR. 3. Preservice Inspection. The preservice inspection program, including finish machining and ultrasonic and surface inspections as described by the applicant, is reviewed and compared with the requirements of Subsection II.3 of this SRP section. The extent to which the proposed ultrasonic inspections and the acceptance criteria in the SAR agree with ASME Code, Section III, NB-2530 for plate materials or NB-2540 for forgings, should be evaluated. 4. Flywheel Design. The stress analysis procedures in support of the flywheel design should be reviewed for allowable stresses and applied stresses for the following loading conditions. 5.4.1.1-9 Revision 3 - May 2010 A. Load combinations at normal operating speed, B. Load combinations at design overspeed (definition of and basis for selection of design overspeed should also be reviewed), C. Shaft and bearing load combinations. Further, the fracture mechanics analysis procedures in support of the flywheel design considering existence of undetected flaws should be reviewed. This analysis should consider crack growth for the life time of the flywheel, including extended period of operation. The information given in the SAR should be compared and evaluated against the acceptance criteria in Subsection II.4 of this SRP section. 5. Overspeed Test . The applicant should confirm that an overspeed test will be run in compliance with Subsection II.5 of this SRP section. 6. Inservice Inspection. The inservice inspection program described by the applicant in the plant operational program, including areas to be inspected, methods of inspection, frequency of inspection, and acceptance criteria, is reviewed and compared with the requirements of Subsection II.6 of this SRP section. 7. Operational Programs. The reviewer verifies that the Pre-Service Inspection, Inservice Inspection, and Inservice Testing Programs are fully described and that implementation milestones have been identified. The
