Outline
- EBR-II metal uranium product
- Recast-metal product
- Small-scale polishing-oxide product
- Headend treatment (ZIRCEX)
- Processing (pilot-scale and engineering-scale) 2
EBR-II Driver fuel processing 3
3 Electrorefined uranium dendrite product Cast uranium product ingot
Pyroprocessing - EBR II Driver Fuel Spent Driver Electrorefined Uranium Ingot
HALEU EBR-II Metal Feedstock Progress HALEU as metal from EBR-II is the nearest term feedstock available to support fast-spectrum advanced reactor concepts Processing of EBR-II driver fuel will continue until all driver fuel is processed Production of EBR-II HALEU reguli will continue until all EBR-II driver fuel has been treated Operations ramp up to 7 day/wk, 12 hr/day 0.365 MT produced in 2019 2nd furnace available 2020 - 1 MT/year 5 MT forecast to be available by 2024 5
Recovered U metal Novel Multi-function furnace Large metallic ingot New graphite crucible Low dose rate, small size HALEU metal regulus
HALEU EBR-II Oxide Feedstock Demonstration Polished EBR-II uranium product suitable for thermal spectrum reactors Demonstrated U Polishing in small-scale equipment (using equipment on-hand)
Dissolution of EBR II uranium metal regulus Uranium purification from residual fission products by solvent extraction Precipitation of uranium using peroxide process Uranium oxide produced by calcination 6
