is reviewed, and the location of the test specimens and their orientation are verified. Information regarding calibration of instruments and equipment is reviewed for conformance to Code Section III, paragraph NB-2300. In the event that none of the fracture toughness tests has been performed, the preliminary safety analysis report (PSAR) must contain a statement of the applicant's intention to perform this work in accordance with Code Section III, NB-2300 and Appendix G of 10 CFR Part 50. The final safety analysis report (FSAR) is reviewed to ensure that all the impact tests shown in NB-2300 have been performed. The results of the tests shall be in accordance with the acceptance criteria shown in subsection II.5 of this SRP section. The reviewer evaluates the predicted end-of-life Charpy upper shelf energy and adjusted reference temperature for the reactor vessel materials in accordance with 10 CFR 50, Appendix G, paragraph IV.B. Reactor vessel materials that do not meet the specified end-of-life acceptance criteria are reviewed in accordance with paragraphs V.C and V.D of 10 CFR 50, Appendix G. NUREG-0744 (Reference 22) provides an acceptable 76 methodology for performance of fracture analysis for demonstrating adequate margins of safety for continued operation in accordance with 10 CFR 50, Appendix G, paragraph V.C.3.77 For those plants that were designed and constructed prior to the effective date of Appendix G, 10 CFR Part 50, some of the fracture toughness requirements of Appendix G may not be explicitly met. The detailed procedure for conducting the review of such cases is found in SRP Section 5.3.2, "Pressure-Temperature Limits," and in MTEB Branch Technical Position 5-2, "Fracture Toughness Requirements." Exemptions from the regulation can only be granted when the applicant has demonstrated equivalence to the required margin of safety. DRAFT Rev. 2 - April 1996 5.3.1-16 6.
