I. Background

The NRC considers Advanced Manufacturing Technologies (AMTs) to consist of material processing and component fabrication methods that have not been traditionally used in the U.S. nuclear industry and have not yet received NRC approval through NRC-endorsed codes and standards or the approval of an industry submittal. There are several regulatory paths available to a licensee for utilizing an AMT in a nuclear application, including: (1) Development of a code or standard that can be incorporated by reference in § 50.55a of chapter I of title 10 of the Code of Federal Regulations (10 CFR); (2) selection of an unregulated in service application; (3) submission of generic technical reports or plant-specific submittals for NRC approval; or (4) implementation of the 10 CFR 50.59, “Changes, tests and experiments,” 10 CFR 70.72, “Facility changes and change process,” or 10 CFR 72.48, “Changes, tests, and experiments” processes. The document addresses the processes, consistent with the QA requirements in appendix B to 10 CFR part 50 and in accordance with 10 CFR 50.59, in order to support the staff's performance of potential inspections of a licensee's implementation of these requirements for AMT-fabricated components.

II. Congressional Review Act

This action is a rule as defined in the Congressional Review Act (5 U.S.C. 801-808). However, the Office of Management and Budget has not found it to be a major rule as defined in the Congressional Review Act.

III. Implementation

The staff has added Appendix A, “Disposition of Public Comments,” to the final document to inform the reader how public comments were dispositioned. The Division of New and Renewed Licenses of the Office of Nuclear Reactor Regulation will transmit the final version of the document (ADAMS Accession Number ML21155A043) to each of the NRC Regional Offices via a memo to be issued concurrently with publication of this Federal Register notification.
