ision 1 The NRC requires the Code Case N-770 examinations to be performed as an augmented inspection program under 10 CFR 50.55a(g)(6)(ii)(F). The latest version of Code Case N-770 approved by the NRC is incorporated by reference in 10 CFR 50.55a. The staff expects to review the latest Code-approved version of Code Case N-770 for incorporation directly in 10 CFR 50.55a under 10 CFR 50.55a(g)(6)(ii)(F). 0/21E N-784 Experience Credit for Ultrasonic Examiner Certification, Section XI, Division 1 Code Case N-784 reduces the requirements for training and experience in regard to examination personnel. Examination personnel would receive less training and experience with respect to the detection of representative flaws in materials and configurations found in nuclear power plants. In addition, the Code Case would allow personnel without nuclear ultrasonic examination experience to qualify without exposure to the variety of defects, components, examination conditions, and regulations that would be encountered. The impact of reduced training and experience has not been evaluated. 4/9/10 N-788-1 Third Party NDE Certification Organization, Section XI, Division 1 The NRC has been following and participating in the development of ANDE for several years, and is reviewing ANDE as it progresses. This code case and the ANDE Standard do not contain sufficient specificity for use as a qualification or certification program. Several important sections of ASME ANDE-1–2015 are not defined and are to be determined in the future by Specific Industry Sector committees. It is not possible for the NRC to evaluate a certification and qualification program that has not been defined. For this reason the N-788-1 and the referenced ASME ANDE-1-2015 are not sufficient on their own as a qualification and certification program able to be used as an alternative to ASME code Section XI Section IWA-2300. 1/17E N-806-1 Evaluation of Metal Loss in Class 2 and 3 Metallic Piping Buried in a Back-Filled
