including: 43 (1) T shall be determined for each material by means of a drop weight test. NDT (2) The materials shall meet the acceptance standards of paragraph NB-2330 of the Code, which states that at a temperature not greater than (T + NDT 33 C)[(T + 60 F)] each Charpy C specimen tested shall exhibit at NDT v 44 least 0.89 mm (35 mils) lateral expansion and not less than 68 J (50 45 ft-lbs) of absorbed energy. 46 (3) When these requirements are met, T is defined as the reference NDT temperature, RT . In the event that the above requirements are not met, NDT additional C notch impact tests are performed (in groups of three v specimens) to determine the temperature T at which they are met. In this cv case the reference temperature RT = T - 33 C (RT = T - 60 F) . NDT cv NDT cv 47 Thus the reference temperature RT is the higher of T and (T - NDT NDT cv 33 C) [(T - 60 F)] cv 48 (4) When a C impact test has not been performed at (T + 33 C) [(T + v NDT NDT 60 F)] , or when the C impact test at (T + 33 C) [(T + 60 F)] 49 50 v NDT NDT does not exhibit a minimum of 68 J (50 ft-lbs) and 0.89 mm (35 mils) 51 52 lateral expansion, a temperature representing a minimum of 68 J (50 ft-lbs) and 0.89 mm (35 mils) lateral expansion may be obtained from a 53 54 full C impact curve developed from the minimum data points of all the C v v impact tests performed. b. In addition to the above criteria, the requirements of paragraphs IV.A.1, IV.A.2, 55 and IV.A.3 and IV.B of Appendix G of 10 CFR Part 50 shall be met. 56 (1) Standard Review Plan Section 5.3.2, "Pressure-Temperature Limits," discusses the requirements of paragraphs IV.A.2 and IV.A.3 of 57 Appendix G in detail. (2) The acceptance criteria discussed in paragraph IV.BA.1 of Appendix G 58 states that reactor vessel beltline materials shall have a minimum uppershelf energy as determined from Charpy V-notch impact tests on unirradiated specimens in accordance with paragraph NB-2322a of the 59 Code, Section III, of 102 J (75
