The state lab and Valar's joint update of 23 January 2026 (run by ETV) says site work for the Ward 250 reactor and the fuel fabrication facility included earthmoving and crushing of about 40,000 cubic yards by TSJ Construction, blasting by 3 Rivers Blasting under contract to TSJ, and more than 4,000 cubic yards of foundation concrete from Nelson's Construction; the lab added cameras, access controls, a planned security checkpoint and a new perimeter fence. The Utah Energy Research Board heard on 11 February 2026 that Valar was 'on track' for its July 4 goal and that the reactor vessel was due at the site shortly; the unfueled reactor arrived by air at Hill AFB on 15 February and then by road (orig-030). DOE's April 2026 environmental review describes construction in the past tense (plan-004). Earlier records name Kiewit (engineering and construction), Goree (design) and Sprung (building) (orig-067); Emery County's commission itself voted the building permit because the county building department had not issued one (gov-021); a utility district recorded an unauthorized sewer tie-in (loc-015); the State Fire Marshal declined the fire review (loc-018). No record read says the fuel building is finished.
