Valar's unlisted, unfinished post dated 28 June 2026 says Ward 250 underwent 'extremely rigorous non-nuclear testing' at its headquarters in Hawthorne, California, before it reached Utah, with temperatures above 750 C and pressures over 6 MPa, thermal cycling and transients; the whole reactor system is six high-cube shipping containers. DOE's Fuel Line Pilot Program page lists the company as 'Valar Atomics Inc. (Hawthorne, California)'. On 29 September 2026 its public job board lists 71 of 92 openings in Torrance, California, including a graphite production lead for machining 'reactor components', CNC programmers, machinists, a welding lead for welds to 'nuclear-grade specifications', and eight turbomachinery roles; two posts name Hawthorne as a work base (a Torrance-listed commercial project manager to 'operate in both Hawthorne and Utah', and an Orangeville-listed people-operations director to be based in or relocate to Hawthorne), and a Utah post mentions travel to the 'Los Angeles headquarters'. The Carbon County claim notice carries a Torrance address (orig-036). In short: reactors and their parts are designed, machined and tested in the Los Angeles area; Utah is where they are fuelled and run. Non-nuclear heat tests are not limited by the nuclear safety limits in the NSDA (a 650 C limit versus 750 C goals, disc-002), so the 750 C figure is not a conflict with them.
