ires that the requirements of Appendix G to 10 CFR Part 50, "Fracture Toughness Requirements," be met unless an exemption is granted based upon proposed alternatives. Appendix G applies to bolting and fastener materials in pressure- retaining components of the reactor coolant pressure boundary with specified minimum yield strengths not over 896 MPa (130,000 psi). Appendix G describes tests and other requirements applicable to these items.4 3. General Design Criterion 1 (GDC 1), "Quality Standards and Records," requires (in part) that: a. SSCs important to safety be designed, fabricated, erected, and tested to quality standards commensurate with the importance of the safety functions to be performed; b. A quality assurance (QA) program shall be established and implemented to provide adequate assurance that these SSCs will satisfactorily perform their safety functions; and c. Appropriate records for the design, fabrication, erection, and testing of SSCs important to safety shall be maintained by the licensee.5 4. General Design Criterion 2 (GDC 2), "Design Bases for Protection Against Natural Phenomena," requires (in part) that SSCs important to safety be designed to withstand the effects of natural phenomena such as earthquake, tornado, hurricane, tsunami, and seiche without loss of capability to perform their safety functions.6 5. General Design Criterion 4 (GDC 4), "Environmental and Dynamic Effects Design Bases," requires (in part) that SSCs important to safety be designed to accommodate the effects of, and be compatible with, environmental conditions associated with normal operation, maintenance, testing, and postulated accidents, including loss-of-coolant accidents (LOCAs).7 3.13-3 DRAFT Rev. 0 - April 1996 6. General Design Criterion 14 (GDC 14), "Reactor Coolant Pressure Boundary," requires (in part) that the RCPB be designed, fabricated, erected, and tested in a manner that provides assurance of an extremely low probability of abnormal leakage, rapidly
