Valar publishes one version of the Ward 250 Nuclear Safety Design Agreement (No. 100403, Revision 02, dated October 2025). The Internet Archive holds seven captures of that PDF (7 November 2025; 1 January, 3 March, 5 July, 6 July, 6 August and 18 September 2026); with the live file Valar Watch fetched on 29 September 2026, all eight are byte-identical (the same SHA-256), and each carries the fuel line 'Fuel Enrichment 4.95% U-235 LEU limits'. So the public copy was not revised after DOE's packaging review approved shipping HALEU fuel to Ward 250 (20 May 2026, safe-010) or after the reactor's first criticality (18 June 2026, orig-010). The agreement itself says that if the fuel differs from its specification, the safety assumptions will be updated in the later Preliminary Documented Safety Analysis, of which no public copy was found (safe-007); an updated analysis may exist. The companion Quality Assurance Program Description (No. 100474, Revision 02) is likewise unchanged across its six copies.
