As of 29 September 2026: DOE's list of B5.26 advanced-reactor NEPA determinations names only 'Valar Ward250 Research Reactor' for Valar; no NSDA, QA program, safety analysis, emergency plan or radiation monitoring plan for any Carbon County facility appears in Valar's public documents, DOE sources or state records read. The state Trust Lands memorandum leaves the emergency planning zone to future licensing and relays Valar's own safety description (csite-009); it describes fuel manufacturing from HALEU, LEU+ or LEU on site (csite-007), spent-fuel storage only on land Valar would buy (csite-008), and both DOE and NRC as possible regulators (csite-010); Utah's 2026 waste-storage exemption fits state-owned test sites, not a private commercial campus (csite-023). Valar's Castle Country page is headed 'Carbon & Emery County, Utah' but its safety section describes only Ward 250 (csite-027). Which federal agency would review a Carbon reactor, and whether its environmental review would be public, is open.
