NIA submitted a public comment on the Department of Energy (DOE) notice of proposed rulemaking (NOPR). NIA appreciates DOE’s efforts to streamline and simplify its regulations in this NOPR. This comment outlines concerns regarding: (1) the proposed sunset of 10 CFR Part 840, and (2) the limited explanation provided for the regulations proposed for sunset. As a result, we offer the following comments, including two recommendations.

The Office of Information and Regulatory Affairs (OIRA) is under the Office of Management Budget, which is part of the Executive Office of the President. Executive order, “Ensuring Accountability for All Agencies” (EO 14215), issued on February 24th, 2025, requires all independent safety agencies to undergo an OIRA review. The Nuclear Regulatory Commission (NRC) must now submit its rulemaking and guidance for a significance determination. If determined to be significant, a proposed rule would go through the EO 12866 OIRA review process that has governed all traditional cabinet departments and agencies since 1993. The purpose of this tracker is to provide insight into the impact of the OIRA process on the rulemaking timeline. Originally published in May of 2026, this resource is updated as new information becomes available.

NIA submitted a public comment on the NRC's Part 57 rulemaking (RIN 3150-AL36; NRC-2025-0379). This letter addresses NIA's highest-priority recommendations for the final rule. NIA believes the following items from both the proposed rule and draft guidance language (NUREG-2271) should be addressed before finalizing the rule. This Part 57 rulemaking is the most significant and complex action NRC has taken thus far under Executive Order 14300 rule rewrite. NIA addressed some of the questions NRC asked stakeholders in an extensive but concise comment.

This NIA factsheet highlights the expected timeline of the NRC Executive Order 14300 Rulemaking. This timeline helps to provide a quick view of the individual rulemakings populated from the NRC website. Originally published in December of 2025, this resource is updated as new information becomes available.

The U.S. government has substantial efforts underway to develop new nuclear reactors for military purposes. Recent executive orders, together with congressional mandates, establish a coordinated strategy that links national security with mission assurance. 

This updated NIA publication outlines the federal policy framework and the projects, concepts, and solicitations underway to translate policy direction and statutory authority into operational capability. It further provides a comprehensive guide to the concepts and initiatives the government is pursuing to develop new nuclear reactors for military purposes.  

NIA submitted a public comment on the Draft Interim Staff Guidance: “NRC Application Pathway for  Reactor Designs Previously Authorized by U.S. Department of Energy or Department of War.” NIA supports the Commission’s objective of enabling more efficient licensing pathways by appropriately leveraging prior federal work. If implemented effectively, this pathway could reduce unnecessary duplication, improve regulatory predictability, accelerate deployment timelines, and better align federal demonstration efforts with successful commercial deployment outcomes. As noted in NIA’s recent comments on the related proposed rulemaking, however, efficiency alone is not sufficient. To succeed over the long term, this pathway must also preserve and visibly reinforce the NRC’s independence, credibility, transparency, and predictability.

Since its enactment of the Accelerating Deployment of Versatile, Advanced Nuclear for Clean Energy (ADVANCE) Act on July 9, 2024, the U.S. Nuclear Regulatory Commission (NRC) has made steady progress implementing it. The NRC is tracking its ADVANCE Act deliverables for 36 milestones on a public dashboard. This brief summarizes NRC's progress. 

As of the end of April 2026, the NRC has completed 31 of the 36 identified ADVANCE Act actions and 2026 deliverables.

NIA submitted a request for an extension of the comment period for the Part 57 Rulemaking. Due to the length of the proposed rule and the importance of the rulemaking, NIA requests that the public comment period be extended an additional 45 days for a total of 90 days, pushing the end of the public comment period to July 30th, 2026. 

NIA submitted a public comment on the proposed NRC Reviews of Reactor Designs Previously Authorized by U.S. Department of Energy or Department of War rulemaking published on April 2nd, 2026. NIA supports the Commission’s objective of enabling more efficient licensing pathways by leveraging prior federal work. However, efficiency alone is not sufficient. For this pathway to succeed, it must also preserve, and visibly reinforce, the NRC’s independence, credibility, and predictability. These attributes are essential not only for safety but for durable regulatory reform that can withstand public scrutiny as well as changes in administrations and markets. This comment described key areas where additional clarification would strengthen the rule and improve its effectiveness.
