Outline
* EBR-II metal uranium product
    - Recast- metal product
    - Small-scale polishing- oxide product
* Aluminum or Zirconium clad HEU fuels
    - Headend treatment (ZIRCEX)
    - Processing (pilot-scale and engineering-scale) 2
 
EBR-II Driver fuel processing Electrorefined uranium dendrite product Cast uranium product 3 ingot 3
 
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 Recovered U metal    Large metallic ingot      New graphite crucible                              Low dose rate, small size Novel Multi-function furnace  HALEU metal regulus 5
 
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 Uranyl Peroxide                  Uranium Oxide Low dose rate, small size Uranium Trioxide HALEU metal regulus U metal dissolution  U purification 6
 
U metal regulus Uranyl Peroxide - UO2(O2).4H2O UO2 pellets EBR-II oxide product characteristics
* All metal species except uranium were below analytical detection limits
* Uranium isotopic analysis (same as metal)
    - U-235: 19.77%
    - U-238: 79.5 %
    - U-234: 0.18%
    - U-236: 0.55 %

Process scale-up
* Design of pilot-scale processing glove box line for clean or lightly irradiated materials - in progress
    - Dissolution/solvent extraction/
conversion/waste vitrification
* EBR-II product (19.7% HALEU)
* ZIRCEX pilot plant product (unirradiated HEU)
* Other fuel/orphan materials

2021 - Planned Activities
* EBR-II
    - Continue processing EBR-II driver fuel
    - Continue to recast previously processed EBR-II uranium product into reguli
    - A total of 1 MT of HALEU reguli will be produced per year
* ZIRCEX
    - Complete testing of Zr and Al simulated fuels
    - Initiate testing of unirradiated HEU fuel
    - Complete design of pilot-scale glovebox line for polishing EBR-II product and ZIRCEX HEU product
    - Complete conceptual design of Hybrid-ZIRCEX Engineering-Scale Demonstration
    - Initiate NEPA (Environmental Assessment) for Hybrid-ZIRCEX Engineering-Scale Demonstration
    - Complete construction of in-can vitrification pilot plant 13}}
