-1 and Figure PTLRr- 2., -The pressure vessel steel surveillance program (Ref. 5 as modified by Ref. 10) is in compliance with Appendix H to 10 CFR 50, entitled, "Reactor Vessel Material Surveillance Program Requirements." The ý"ma6terial test and the acceptance standard utilize the reference nil-ductility temperature, RTNDT, which is determined in accordance with ASTM E208. The empirical relationship'between RTNDT and the fracture toughness of the reactor vessel steel is developed in accordance with Appendix'G, "Fra6ture Toughness Criteria for'Protettion Against Failure," to section Xl of the ASME Boiler andPressure Vessel .Code. The surveillance capsule removal schedule meets the requirements of ASTM E185-82.As shown by Reference 10 (Appendix D), the reactor vessel material irradiation surveillance specimens indicate that the surveillance data meets the credibility idisCUssioh presented in Regulatory Guide' 1.99 Revision 2where:" 1. The capsule, materials represent the limiting reactor vessel material.2.
