Note: The NRC unconditionally approved Code Case N-613-2 in RG 1.147. 7/30/98 N-615 Ultrasonic Examination as a Surface Examination Method for Category B-F and B-J Piping Welds, Section XI, Division 1 The Code Case requires the ultrasonic technique used to be demonstrated capable of detecting certain size flaws on the outside diameter of the weld, but it does not specify any demonstration requirements. To be acceptable, Section XI, Appendix VIII, rules for performance demonstration need to be developed and applied. Annulled on 1/4/16 N-618 Use of a Reactor Pressure Vessel as a Transportation Containment System, Section XI, Division 1 The Code Case was developed as a potential option for shipping and disposal of a reactor pressure vessel (RPV).

The regulations in 10 CFR Part 71, “Packaging and Transportation of Radioactive Material,” address the use of RPVs as a transportation package (Ref. 16). 5/13/20 DG-1408, Page 33 CODE CASE NUMBER TABLE 5 ANNULLED OR SUPERSEDED UNACCEPTABLE SECTION XI CODE CASES ANNULLMENT OR REVISION DATE N-622 Ultrasonic Examination of RPV and Piping, Bolts, and Studs, Section XI, Division 1 The Code Case was published in May 1999. Industry performance demonstration initiative efforts since that time have made this Code Case obsolete. Separate Code Cases are addressing issues associated with supplements to Section XI, Appendix VIII, individually. Annulled on 1/12/05 N-653 Qualification Requirements for Full Structural Overlaid Wrought Austenitic Piping Welds, Section XI, Division 1 a. Section XI, Appendix VIII, Supplement 11, requires a personnel performance qualification as part of the procedure qualification.
