Content:
f flow-induced vibration and acoustic resonance for RPV internals is performed under SRP Section 3.9.2. 4. Evaluation of the adequacy of the structural integrity design of the RPV internals, including adequacy the of design fatigue curves for reactor internals materials to account for cumulative reactor service-related environmental and usage factor effects and consideration of each combination of design, service, and postulated event loadings is performed under 3.9.3. 5. Evaluation of the adequacy of the mechanical design of the control rod drive system, including the control rod drive elements is performed under SRP Section 3.9.4. 6. Review of the adequacy of programs for assurance of integrity of bolting and threaded fasteners is performed under SRP Section 3.13. 7. Evaluation of the adequacy of analyses justifying exclusion of certain postulated pipe ruptures from design bases is performed under SRP Section 3.6.3 8. Verification of fuel system design, including fuel behavior effects on reactor core design under various normal and accident operating conditions is performed under SRP Section 4.2. 9. Review of material aspects of reactor internals is performed under SRP Section 4.5.2. The specific acceptance criteria and review procedures are contained in the referenced SRP sections. II. ACCEPTANCE CRITERIA Requirements Acceptance criteria are based on meeting the relevant requirements of the following Commission regulations: 1. GDC 1 and 10 CFR 50.55a require that reactor internals be designed to quality standards commensurate with the importance of the safety functions performed. 2. GDC 2 requires that reactor internals be designed to withstand the effects of natural phenomena such as earthquakes without loss of capability to perform safety functions. 3.9.5-5 Revision 3 - March 2007 3. GDC 4 requires that reactor internals be designed to accommodate the effects of and to be compatible with the environmental conditions associated with normal operations,
