Deseret News (17 Mar 2026, and again 18 Jun 2026) reports that Willem Kriel came out of retirement to help lead Valar's engineering team, and names him with Mark Mitchell and Muhammad Shahzad as experienced hires; it gives no earlier employer. A Willem Kriel co-authored 'PBMR Project - Pebble Fuel Advantages', a paper on South Africa's Pebble Bed Modular Reactor fuel given at a 2006 nuclear conference in Seoul and indexed by DOE's OSTI database; the record lists two affiliations, PBMR Ltd. (Gauteng, South Africa) and Westinghouse Electric Company (Windsor, US), and its marker places Kriel with the second group (Westinghouse), not with PBMR Ltd. The name and field match the Deseret account, but no source read states that the Valar engineer is that author, and his other papers found under that name could not be read (sources_not_read). Valar's own pages and public documents do not name him, and his title at Valar is not public. When he joined is not stated. For what became of PBMR, see ppl-015.

In plain termsDeseret News reports that a retired engineer, Willem Kriel, helps lead Valar's engineering. An engineer of the same name wrote about South Africa's earlier helium-cooled, TRISO-fuel reactor program, which would be relevant experience, but no source we read confirms they are the same person.

verified 2026-09-29: Re-read Deseret (both articles) and the OSTI record (HTML author markup). Fixed: the headline called him 'a veteran of South Africa's pebble-bed reactor program', which no source read states; the first draft gave his affiliation as PBMR Ltd., but the OSTI markup places the affiliation marker [2] (Westinghouse Electric Company, Windsor) after his name; date was the report date, now null (joining date unknown). A web search found no readable source linking the two; login-only pages not used. Correction 2026-09-29 (wording review): source excerpt shortened to the public-role words; note on unused sources shortened.
