- The groundbreaking date: the joint release by the state energy office, its lab and Valar was published on 17 September 2025 and says the launch 'coincides with the 24th anniversary of 9/11', i.e. the ceremony was on 11 September. Valar's '09.17.2025' matches the release date, not a different event.
- Utah Business carried the same joint release, dated 17 September 2025.
- The '14 days' count: the unfinished page opens 'It's been two weeks since Ward 250 went critical' and says it 'made power on July XX', so it reads as drafted in early July (two weeks after 18 June) under an earlier date field; its count is consistent with the 18 June criticality.Ward 250 By the Numbers (Isaiah Taylor; unlisted page that still carries placeholders) (Valar Atomics, 2026-06-28)
The gap: Valar's Series B post says electricity came 'just a week' after criticality; its own website dates the two 13 days apart (18 June and 1 July). The two other mismatches first recorded here have innocent explanations: the '14 days' page is an unfinished draft apparently written in early July, and '09.17.2025' is the date of the joint press release for a groundbreaking held on 11 September.
In plain termsThis is a small slip, not a safety issue. Valar's Series B post says the reactor made electricity 'just a week' after first going critical; its own website dates the two events 13 days apart. Two other date mismatches first listed here turned out to have ordinary explanations: a page counting '14 days' since criticality appears to have been written in early July and left with an earlier date, and Valar's '17 September' groundbreaking is the day the press release went out for a ceremony held on 11 September.
Why it matters: Minor: a company's public timeline should match its own records.
What would settle it: Ward 250's startup log (FOIA to DOE Idaho Operations Office) for the criticality and 1 July dates; the state's groundbreaking records.
