Document 2026-03866 is a Proposed Rule published by the Department of Energy in the Federal Register on February 26, 2026, with an effective date of January 21, 2026. On January 21, 2026, the U.S. Department of Energy ("DOE") published a notice of proposed rulemaking ("NOPR") seeking to amend certain regulations for worker safety and health to expedite the review, approval, and deployment of advanced reactors under DOE's jurisdiction, including qualified test reactors in DOE's reactor pilot program consistent with a recent Executive order. The NOPR provided an opportunity for submitting written comments, data, and information by February 20, 2026. By letter dated February 4, 2026, the American Federation of Labor and Congress of Industrial Organizations ("AFL- CIO") requested a 45-day extension to the comment period. DOE has reviewed this request and is re-opening the public comment period until March 23, 2026.
