Content:
used to minimize flaws and improve mechanical properties is reviewed to establish that sufficient information is provided to permit an evaluation of the adequacy of the flywheel materials. 2. Fracture Toughness The fracture toughness of the materials, including materials tests, correlation of Charpy specimens to fracture toughness parameters, or the alternate use of a nil-ductility transition reference temperature (RT ), are reviewed to establish that the flywheel NDT materials will exhibit adequate fracture toughness at normal operating temperature (Ref. 2) . 6 3. Preservice Inspection The descriptive information is reviewed to verify that the bore of the flywheel is machined to final dimensions if it is flame cut, and that ultrasonic and surface inspections are performed on all finished machined surfaces. 4. Flywheel Design The flywheel design information including allowable stresses, design overspeed considerations, and shaft and bearing design adequacy, is reviewed. 5. Overspeed Test The applicant's overspeed test procedures are reviewed to establish their adequacy. 6. Inservice Inspection A description of the preservice and postoperational phases of the inservice inspection program, including types of inspections, areas inspected, frequencies of inspection, and flaw acceptance criteria, is reviewed. 5.4.1.1-3 DRAFT Rev. 2 - April 1996 Review Interfaces:7 In addition, the EMCB will coordinate another branch's evaluation that interfaces with the overall review of the system as follows:8 The review for quality assurance is coordinated and performed by the Quality Assurance and Maintenance Branch (QAB)(HQMB) as part of its primary review responsibility for Standard 9 Review Plan Sections 17.1 and 17.2Chapter 17 . The acceptance criteria necessary for the 10 review and the methods of application are contained in individual sections of the referenced SRP sectionChapter . 11 II. ACCEPTANCE CRITERIA The MTEBEMCB acceptance criteria are based on meeting the relevant
