The Trust Lands staff memo for the 17 September 2026 board meeting, in its 'Applicant' background section, states that Ward 250 'reached full power operations on June 21, 2026' and generated electricity on 1 July. The memo does not say who supplied the date; the next paragraph says 'The applicant represents' what its DOE approvals show. ANS reported on 22 June 2026 that Valar 'is now proceeding with a planned power ascension' and announced that day an output of 10 kWt, a tenth of the reactor's 100 kWt rating. If the reactor was at full power on 21 June, a 22 June announcement of 10 kWt with power ascension still under way does not fit: either the 21 June date is wrong or the 22 June announcement described an earlier step, and no public record says which. On 24 June Valar's Harry Hansen told Price's council the reactor had gone to full power 'shortly after' going critical (plan-006). The memo also says Valar holds a DOE 'Certificate of Readiness' and has 'brought and sustained that reactor through an initial testing campaign'; no such certificate has been published (safe-007, gov-037). The board had these statements in its packet when it approved the lease on 17 September (mine-011, mine-016).
