Stated scope grew from a 12-month test in a temporary facility (2025) to a long-term fuel-and-reactor base (2026)
In July 2025 Valar told an Emery County town hall, and its slides said, that Ward 250 would be a test of about 12 months with 30 effective full-power days in a temporary facility (orig-045), and its safety agreement set a 12-month run and an 18-month life ending in decommissioning. The same 2025 slide deck also projected 'Commercial Deployment by 2028', without naming a site. In September 2025 the state's groundbreaking release, printed by ETV News, ended with Valar's own description of itself as 'building America's first nuclear gigasites', and in October 2025 ETV reported Valar's 'current plan' for a manufacturing hub in Carbon County after about three years; neither named a site (loc-034). By August 2026 the company described the Emery lab as its 'whole Utah operations' including a fuel facility, was acquiring about 110 acres beside it (mine-018), had applied to BLM for a 10,270-acre site near Green River and a second site (mine-006), and on 17 September 2026 the Trust Lands board approved leasing Valar the Carbon County parcel for up to a century, for a reactor, fuel and industrial campus (mine-010, mine-011).
