'CAT scan' spent-fuel claim still on Valar's site; no supporting calculation or correction found there

Valar's April 2025 lawsuit post, still online in late September 2026, says its analysis indicates that holding spent fuel from its 100 kWt 'Ward One' test reactor (planned life under a month) for five minutes gives radiation exposure equal to a CAT scan. Valar's Ward 250 safety paper, the NSDA, credits reactor shielding that 'cannot be inadvertently defeated', analyzes fuel-handling accidents, and plans defueling into storage; DOE's categorical exclusion has the spent core leave in dry storage casks. No Valar correction or published calculation was found on Valar's website as of late September 2026. For scale: a CT scan is about 1 to 10 millisieverts (FDA), so five minutes would need 12 to 120 millisieverts an hour; the post gives no amount of fuel, cooling time, distance or shielding.
