Proposed Worker Safety Rule Changes

On January 21, 2026, DOE published a proposed rule to amend worker safety and health regulations in 10 CFR part 851 so it can speed up review, approval, and deployment of advanced reactors, including qualified test reactors in DOE’s reactor pilot program. The proposal says it is consistent with Executive Order 14301 (issued May 23, 2025) and, according to the document summary, does not impose immediate cost changes while aiming to keep workers safe.

Faster Reactor Testing for Companies

DOE’s proposed rule would revise regulations to enable the Department to expedite review, approval, and deployment of advanced reactors under DOE jurisdiction, including qualified test reactors in the reactor pilot program. The document says this affects companies testing reactors and, per the summary, aims to speed reactor development without immediate cost changes.
