Leading the charge: INL’s role in advancing HALEU production
Idaho National Laboratory is playing a key role in helping the U.S. Department of Energy meet near-term needs by recovering HALEU from federal inventories, providing critical support to help lay the foundation for a future commercial HALEU supply chain. INL also supports coordination of broader DOE efforts, from material recovery at the Savannah River Site in South Carolina to commercial enrichment initiatives.

We present an overview of a semi-empirical kinetic model of chemical reaction product formation due to simultaneous irradiation of carbon by O+ and H+ symbolically represented by O+-H+→C. The model was developed in conjunction with our experimental studies of the O+-H+→C and the O+-H+→C/B irradiation cases; C/B represents boron-doped graphite. Model predictions were made for flux and energy dependence, and generally good agreement with experimental results has been seen for both single-species cases: H+→C and O+→C. For the O+-H+→C reaction, the model agrees quite well with the flux ratio-dependence of the H2O yield, the resulting CO and CO2 yield reductions, and the CH4 yield reduction.
