newrecordconfirmed Quality program: research-reactor QA, not NQA-1; codes usable before full validation; 'Approved' text left unedited
2025-10 · safe-018 · Valar Atomics

Valar's Quality Assurance Program Description (document 100474 rev 02, October 2025, status 'Approved') applies ANSI/ANS-15.8-1995, the research-reactor QA standard, instead of the nuclear industry's NQA-1, which Valar's summary says DOE approved (safe-005). It covers both Ward 250 and the 'Valarin' fuel fabrication facility, together the 'VASR Facility'. It allows 'more modern and efficient computational codes for HTGR applications' to be used 'prior to their complete validation', relying on safety margins, with Ward 250's data to validate them. It permits design verification by people 'from the same organization' and by comparison with the non-nuclear WardZero prototype, and requires an independent QA assessment before fuel loading. The published 'Approved' document contains many unresolved editing marks: merged words ('Comprehensive Ddesign', 'VTalar Atomics', 'Valar AtomicsValarin'), sentences printed twice in old and new wording, and 'Figure 11: VSAR Facility' for 'Figure 1: VASR'. The document says it becomes effective on approval by Valar's own facility director and president, so 'Approved' marks internal approval. The NSDA separately says fuel particles are manufactured under an NQA-1 program. Whether the pre-fuel-load independent QA assessment took place, and by whom, is not public. The safety agreement's case for ANS-15.8 says the standard covers all 18 criteria of 10 CFR 830.122 (pp.49, 54); that rule lists 10 criteria, and 18 is the count in the NRC's Appendix B that NQA-1 follows (exp-025).

In plain termsQuality assurance is the paperwork and checking that make sure things are built and analysed as designed. Valar uses the lighter standard written for university research reactors rather than the heavier nuclear-industry one, and allows some newer computer programs to be used before they are fully proven. Its published quality rulebook, marked 'Approved', still shows half-finished edits. That does not show the reactor was built badly; it shows the public version of a document about careful document control was not itself carefully finished.
verified 2026-09-29: Re-read the QAPD (24 pp., PDF created 7 Oct 2025) on 2026-09-29. Holds: 'Status: Approved', ANS-15.8-1995, codes 'prior to their complete validation', verifiers 'from the same organization', independent assessment before initial fuel loading, and the editing marks ('Ddesign', 'VTalar', 'AtomicsValarin', doubled sentences, 'Figure 11: VSAR'). Added that 'Approved' is Valar's internal approval. Correction 2026-09-29 (calculation audit): added the 18-criteria versus 10 CFR 830.122's 10 point.
