What the agency says
The U.S. Nuclear Regulatory Commission (NRC) is proposing to amend its regulations to augment the existing byproduct material framework to be inclusive of fusion machines. The NRC is proposing requirements that are technology-inclusive to accommodate the wide variety of anticipated fusion machine designs across the National Materials Program. The NRC is also issuing for comment draft guidance for the implementation of this proposed rule, entitled NUREG-1556, Volume 22, "Consolidated Guidance About Materials Licenses: Program- Specific Guidance About Fusion Machine Licenses." The NRC will conduct at least one public meeting to promote full understanding of the proposed rule and to facilitate public comments. We seek comment on all aspects of this proposed rule.
