Uranium Post Mining Groundwater Quality Modeling and Column Testing

Oklo will partner with Pacific Northwest National Laboratory (PNNL), which has demonstrated gram-scale reduction of UF6 to UF4 through an intermediary compound that significantly reduces the traditional method’s hazards. PNNL has also shown the viability of co-reducing fluorides to metal. The possibility of eliminating the intermediate UF4 production step will have the potential of increased throughput and process safety that will help accelerate deployment of a commercial fabrication facility.

GAIN Announces Fourth Round FY 2025 Nuclear Energy Voucher Recipients

November 20, 2025,
DOE’s Gateway for Accelerated Innovation in Nuclear (GAIN) program provides the nuclear community with the technical, regulatory, and financial support needed to move innovative nuclear technologies toward commercialization while ensuring the continued, safe, and economic operation of the existing fleet. GAIN voucher recipients do not receive direct financial awards. Vouchers provide funding to DOE laboratories to help businesses overcome critical technological and commercialization challenges. All awardees are responsible for a minimum 20 percent cost share, which could be an in-kind contribution. This marks the fourth and final round of GAIN vouchers awarded for fiscal year 2025. Please visit the GAIN website for more information on upcoming award rounds.

Chlorine Nuclear Data Measurement and Evaluation, TerraPower

This project will perform new measurements of 35Cl(n,p), analyze the experimental data from these measurements, generate new 35Cl and 37Cl cross-section evaluations in ENDF/B format, and assess the impacts of the expected changes to chlorine nuclear data by comparing analysis of MCRE with updated cross-section libraries to results with existing nuclear data.
