newanalysisreported DOE says its revamped authorization pathway cut more than 900 pages of guidance; UCS says the 2025 rewrite, made without public notice, leaves companies 'significant discretion'

In a statement dated 28 January 2026, the Union of Concerned Scientists said DOE had rewritten in 2025, without public notice, the body of safety and security directives it uses to authorize pilot-program reactors, cutting hundreds of pages of detailed requirements for vaguer standards that leave the private builders significant discretion. Edwin Lyman, UCS director of nuclear power safety, said DOE had created 'a legally dubious framework' to designate these reactors as 'test' reactors and bypass the NRC's authority, and called the changes 'a massive experiment in the deregulation of novel, untested nuclear facilities'. UCS added that pilot reactors used for commercial power would still need NRC licenses, but that the NRC had agreed with DOE to restrict the scope of its added reviews of DOE-authorized designs. The underlying NPR report was not read (npr.org blocks AI readers). Valar's NSDA does cite a set of Office of Nuclear Energy orders ('NE O 151.1', 'NE O 420.1', 'NE O 232.1' and others) rather than the department-wide DOE orders, consistent with a separate NE rulebook (safe-012). DOE's own April 2026 article confirms the scale of the rewrite: it says the old guidance ran over 1,500 pages and the new pathway 'eliminates more than 900 pages' (safe-004). That pages were cut is DOE's statement; that the result is vaguer and gives companies more discretion is UCS's assessment. DOE's published position is in safe-004.

In plain termsA nuclear-safety advocacy group, the Union of Concerned Scientists, says DOE rewrote its reactor safety rules without public notice and made them looser, which gives companies like Valar more room to decide for themselves how to meet them. That is the group's assessment, not a finding by a court or inspector. DOE itself says it cut more than 900 pages, and that its process is 'fundamentally similar' to the NRC's on safeguards and security (safe-004). Valar's own safety agreement does refer to a separate set of 'NE' orders, which fits the report that new rules were written.

verified 2026-09-29: Re-read UCS statement and DOE's 5 Fast Facts on 2026-09-29. Lyman's 'legally dubious framework' words re-attributed exactly (he said DOE created the framework). Added DOE's own statement that it cut more than 900 pages, which corroborates the scale of the rewrite; 'vaguer' and 'discretion' remain UCS's assessment (one source, kind analysis). Correction 2026-10-01 (precision review): wording made more exact against the cited records.
