s for those conclusions. 1. The applicant has sufficiently demonstrated that its selection of materials, fracture toughness test data, design procedures, preservice overspeed spin testing program, and inservice inspection program for the reactor coolant pump flywheels meet the requirements for GDC 1 and 10 CFR Part 50, 50.55a(a)(1) with respect to providing adequate assurance of a quality product commensurate with the importance of the safety function. 2. The applicant has met the requirements of GDC 4 by complying with the guidance of RG 1.14. It selected suitable materials with adequate fracture toughness, used conservative design procedures, and established a preservice testing and inservice inspection programs for reactor coolant pump flywheels. The staff has reasonable assurance that the structural integrity of the flywheels will be maintained in the event of design overspeed transients or postulated accidents. The applicant described the Pre-Service Inspection, Inservice Inspection, and Inservice Testing Programs and its implementation in conformance with 10 CFR Part 50, Appendix A, 10 CFR 50.55a(a)(1) and 10 CFR 50.55a(f). For DC and COL reviews, the findings will also summarize the staff=s evaluation of requirements and restrictions (e.g., interface requirements and site parameters) and COL action items relevant to this SRP section. In addition, to the extent that the review is not discussed in other SER sections, the findings will summarize the staff's evaluation of the ITAAC, including design acceptance criteria, as applicable. V. IMPLEMENTATION The staff will use this SRP section in performing safety evaluations of DC applications and license applications submitted by applicants pursuant to 10 CFR Part 50 or 10 CFR Part 52. Except when the applicant proposes an acceptable alternative method for complying with specified portions of the Commission=s regulations, the staff will use the method described herein to evaluate conformance with Commission
