Two Microsoft Teams webinars, on October 8 and October 14, are the Nuclear Regulatory Commission’s chosen way to walk the public through a 339-page proposal to rewrite parts of its reactor regulations. The sessions run 2 to 3:30 p.m. Eastern on the 8th and 9 to 10:30 a.m. Eastern on the 14th, and the agency says they will give an overview of the proposed rule and related implementation activities and answer questions.
The proposal covers existing plants and new reactor applicants alike. The rule itself was announced on September 11, 2026, under docket NRC-2025-1138, and the October 1 advisory announcing the sessions is the latest entry in the agency’s 2026 news listing.
The September 11 proposal and its docket
The agency’s release on the proposal is titled “NRC Proposes Broad Overhaul of Nuclear Reactor Regulations,” and it carries release number 26-077. It says the changes apply to existing plants and to new reactor applicants, and that they implement Executive Order 14300. Comments go through regulations.gov under docket NRC-2025-1138. The NRC’s 2026 news index lists the proposal beside the October 1 advisory announcing the sessions.
NRC Chairman Ho K. Nieh said the modernization “replaces outdated requirements with smarter, risk-informed approaches reflecting today’s technologies” while keeping “strong safety margins” and removing “unnecessary constraints.” The release adds that the result is a framework meant to be “more efficient, predictable and adaptable to evolving nuclear technologies,” language that signals the direction of the changes: fewer fixed requirements, more room for risk-informed alternatives, and a regulatory structure that treats existing plants and new applicants under one modernization effort rather than in separate tracks.
Earthquake design, control rooms and the other provisions
The American Nuclear Society’s reporting identifies the proposal by its formal name, “Regulatory Enhancements for Reactor Licensing, Decommissioning, and Operational Oversight,” and lists what it touches: risk-informed approaches to earthquake design requirements, removal of the 15-year expiration on standard design approvals, flexibility in operator licensing and training for control rooms, and clarified defect and noncompliance reporting under 10 CFR Part 21. It also covers streamlined nonemergency event reporting and updated decommissioning timelines and trust-fund rules.
The list reaches from how a plant is designed against earthquakes to how a shuttered plant pays for its own decommissioning, which is the range of subjects the October webinars will have to cover in ninety-minute sessions. The NRC’s September 11 release says the changes apply to existing plants and to new reactor applicants and implement Executive Order 14300, so the webinars explain one rulemaking aimed at both groups, and comments on it go to docket NRC-2025-1138 through regulations.gov.
The cost case comes from the agency’s regulatory analysis, as ANS reported it. Both the NRC and the industry it regulates stand to share in the savings, and the analysis projects savings of $311 million to $411 million across industry and the NRC over 30 years, or $15.1 million to $22.2 million a year.
Federal Register timing, comment limits and the October sessions
The NRC’s October 1 advisory says the proposed rule appeared in the Federal Register on September 24, 2026, and describes it as part of the agency’s work implementing Executive Order 14300, in coordination with interagency partners and under the ADVANCE Act. Because the Federal Register date starts the public comment clock, anyone planning to file input has a window that was already running before the webinars were announced. ANS and APPA reported a 30-day period for this proposal, while the agency’s own pages described a period tied to Federal Register publication, so the exact closing date is best confirmed on the docket at regulations.gov.
The agency describes the sessions as briefings, not a filing venue. The September 11 release said the agency would hold a virtual public meeting during the comment period to explain the proposal and answer questions, and that written submissions are not accepted during the meeting itself. Comments go to the docket, so the webinars function as an explanation of the 339 pages for people who do not plan to read all of them. Both sessions are held on Microsoft Teams, the first on October 8 from 2 to 3:30 p.m. Eastern and the second on October 14 from 9 to 10:30 a.m. Eastern, so a reader can attend whichever fits.
This rulemaking is separate from the licensing proposal the agency put out in the summer. That earlier package carries its own docket, NRC-2025-0975, and its own 45-day comment period.
Questions to the agency during the webinar period go to its Office of Public Affairs at 301-415-8200 or [email protected]. The savings range of $311 million to $411 million over 30 years remains the one quantified claim in the record for what the overhaul is worth, and it comes from the NRC’s own regulatory analysis.
