RFI U-10Mo Fuel Fabrication

The National Nuclear Security Administration (NNSA) has issued a Request for Information (RFI) seeking industry capability and interest for the fabrication of high‑assay low‑enriched uranium‑molybdenum (U‑10Mo) monolithic fuel, intended for U.S. research and test reactors. The RFI asks respondents to indicate whether they can supply the alloy, fabricate fuel plates and assemblies, or provide a full‑service solution, and to submit a Letter‑of‑Interest by the deadline. The effort envisions a future market of roughly 10,000 plates and 200 elements per year (≈ 3,000‑3,500 kg HALEU annually) with an estimated total market value of $100 M‑$175 M. Respondents must outline capabilities in vacuum induction melting, hot‑rolling, hot‑isostatic pressing, non‑destructive testing, and compliance with NRC Category II (or DOE Hazard III) licensing requirements. • Scope options: alloy supply only, plate/assembly fabrication only, or full‑service (preferred). • Required equipment includes VIM casting, hot‑roll mills, HIP system, electron‑beam welder, rolling mills, inspection and testing stations – roughly 30 major items, with major equipment to be provided by NNSA. • Facility must accommodate a ~25,000 ft² high‑bay, meet Category II nuclear safety standards, and obtain NRC or DOE licensing. • Timeline: RFI issued 9 Sep 2026; LOI due 21 Dec 2026; supplier‑development planned for late‑2020s and production capability targeted for mid‑2030s. • Contact: Chris Martin, Contracting Specialist, PNNL.
