II. Executive Order 14300: Ordering the Reform of the Nuclear Regulatory Commission

On May 23, 2025, President Donald J. Trump signed Executive Order (E.O.) 14300, “Ordering the Reform of the Nuclear Regulatory Commission.” This rulemaking addresses Section 5, “Reforming and Modernizing the NRC's Regulations,” which requires the NRC to undertake a review and wholesale revision of its regulations and guidance documents, consistent with the policies set forth in section 2 of the E.O. ( printed page 51601)

III. Rulemaking Procedure

Because the NRC considers this action to be non-controversial, the NRC is publishing this proposed rule concurrently with a direct final rule in the Rules and Regulations section of this issue of the Federal Register . The direct final rule will become effective on October 26, 2026. However, if the NRC receives significant adverse comments by September 10, 2026, then the NRC will publish a document that withdraws the direct final rule. If the direct final rule is withdrawn, the NRC will address the comments in a subsequent final rule. Absent significant modifications to the proposed revisions requiring republication, the NRC will not initiate a second comment period on this action in the event the direct final rule is withdrawn.

A significant adverse comment is one in which the commenter explains why the rule would be inappropriate, challenges the rule's underlying premise or approach, or argues that the rule would be ineffective or unacceptable without a change. A comment is adverse and significant if:

(1) The comment opposes the rule and provides a reason sufficient to require a substantive response in a notice-and-comment process. For example, a substantive response is required when:

(a) The comment causes the NRC to reevaluate (or reconsider) its position or conduct additional analysis;

(b) The comment raises an issue serious enough to warrant a substantive response to clarify or complete the record; or

(c) The comment raises a relevant issue that was not previously addressed or considered by the NRC.

(2) The comment proposes a change or an addition to the rule, and it is apparent that the rule would be ineffective or unacceptable without incorporation of the change or addition.

(3) The comment causes the NRC to make a change (other than editorial) to the rule.

For procedural information and the regulatory analysis, see the direct final rule published in the Rules and Regulations section of this issue of the Federal Register .

IV. Background

The U.S. Nuclear Regulatory Commission (NRC) is undertaking a series of regulatory updates to modernize its administrative framework, align with government-wide requirements, and ensure continued compliance with evolving federal standards related to transparency, advisory committee governance, information management, and personnel security. These are consistent with the directive in E.O. 14300, “Ordering the Reform of the Nuclear Regulatory Commission,” which requires the NRC to conduct a comprehensive review of its regulations.

First, the NRC is updating its information withholding provisions in 10 CFR 2.390 to clarify the Commission's procedures for evaluating requests for withholding proprietary and sensitive information from public disclosure. The revisions to 10 CFR 2.390 align with a recent modification made to that regulation to alleviate the need for licensees or applicants filing a withholding request to include information regarding competitive harm (90 FR 54225; November 26, 2025). The revisions in this rule maintain the NRC's longstanding policy balance between protecting sensitive commercial or financial information and ensuring transparency in agency decision making. The changes are administrative in nature and are intended to improve clarity and consistency in how information is reviewed and processed.

Second, the NRC is revising a provision in 10 CFR 2.804 that established procedural requirements related to post-promulgation comment periods. This provision is not statutorily required and thus imposes unnecessary administrative burdens. Revision of this provision provides additional flexibility to rulemaking processes.

Third, the NRC is revising 10 CFR part 7 to align its advisory committee regulations with the government-wide Federal Advisory Committee Act (FACA) requirements administered by the General Services Administration (GSA). On December 16, 2026, GSA issued a final rule (90 FR 58408) modernizing FACA regulations by updating definitions, improving reporting requirements, and incorporating contemporary practices for advisory committee operations and technology. To ensure consistency with these standards and continued compliance with FACA, the NRC is making conforming amendments throughout 10 CFR part 7. These revisions update terminology, clarify procedural expectations, and consolidate administrative requirements to reflect GSA's current regulatory framework. The amendments do not impose substantive requirements on NRC licensees or external stakeholders; instead, they improve the efficiency, transparency, and accountability of NRC advisory committee management.

Finally, the NRC is revising its personnel security regulations in 10 CFR part 10 to reflect Federal adjudicative standards established in the Office of the Director of National Intelligence's Security Executive Agent Directive 4 (SEAD 4). SEAD 4 sets forth uniform adjudicative guidelines for determining eligibility for access to classified information and sensitive national security positions across the executive branch. The NRC previously incorporated SEAD 4 into Management Directive 12.3, “Personnel Security,” and is now codifying these requirements to ensure alignment between internal policy and regulatory text. This codification enhances transparency and promotes consistent expectations for individuals requiring an access authorization or employment clearance.

Collectively, the actions in this rulemaking modernize NRC regulations, improve alignment with federal policies, and enhance administrative efficiency while maintaining transparency, public participation, and national security protections consistent with the NRC's statutory responsibilities.

V. Plain Writing

The Plain Writing Act of 2010 (Pub. L. 111-274) requires Federal agencies to write documents in a clear, concise, and well-organized manner. The NRC has written this document to be consistent with the Plain Writing Act as well as the Presidential Memorandum, “Plain Language in Government Writing,” published June 10, 1998 (63 FR 31883). The NRC requests comment on this proposed rule with respect to clarity and effectiveness of the language used.

VI. Paperwork Reduction Act

This proposed rule does not contain any new or amended collections of information subject to the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.) and, therefore, is not subject to the requirements of the Paperwork Reduction Act of 1995.

VII. Executive Orders

The following are Executive orders that are related to this proposed rule:

A. Executive Order 12866: Regulatory Planning and Review (as Amended by Executive Order 14215, Ensuring Accountability for All Agencies)

The Office of Information and Regulatory Affairs (OIRA) has determined that this proposed rule is not a significant regulatory action.

B. Executive Order 14154: Unleashing American Energy

The NRC has examined this proposed rule and has determined that it is ( printed page 51602) consistent with the policies and directives outlined in E.O. 14154.

C. Executive Order 14192: Unleashing Prosperity Through Deregulation

This action is determined to be a deregulatory action as defined by E.O. 14192. Details on the estimated costs of this proposed rule can be found in Section VI, “Regulatory Analysis,” of the direct final rule document.

D. Executive Order 14270: Zero-Based Regulatory Budgeting To Unleash American Energy

E.O. 14270 requires the NRC to insert a conditional sunset date into all new or amended NRC regulations provided the regulations are (1) promulgated under the Atomic Energy Act of 1954, as amended (AEA), the Energy Reorganization Act of 1974, as amended (ERA), or the Nuclear Waste Policy Act of 1982, as amended (NWPA); (2) not statutorily required; and (3) not part of the NRC's permitting regime. The NRC determined that the regulatory changes proposed in this rule are for processes that are required by statute and are part of the NRC's regulatory permitting scheme authorized by the AEA, ERA, or NWPA. Therefore, the NRC views this rulemaking to be outside the scope of E.O. 14270 and did not insert conditional sunset dates for the regulatory changes in this proposed rule.

E. Executive Order 14300: Ordering the Reform of the Nuclear Regulatory Commission

The NRC has examined this direct final rule and has determined that it is consistent with the policies and directives outlined in E.O. 14300.
