Keep going for information on SRNL family colors.
SRNL and Savannah River Site Overview• Operated since mid-1950’s
– SRNL and SRS have Integrated Fuel Cycle Management Capabilities
• Produced 301MT 4.95% LEU from 2003 to 2011 (TVA)– Recycling of HEU and LEU Spent Nuclear Fuel (SNF)– Flowsheets analyzed and validated at SRNL
• 2020 SNF Recycling Operations– High Flux Isotope Reactor (HFIR) Fuel– Material Test Reactor (MTR) Fuels– Liquid HEU Target Material
• Currently Storing HEU Solution (~2MT 19.75% eq) – Awaiting Decision on Next Steps
• Blend-down to 4.95% -OR-• Dump as Waste –OR-• Produce HALEU?

Capability to Produce HALEU• ~2MT 19.75% HALEU (equiv.) in Tanks
– Uranyl Nitrate Solution• Significantly More Can be Produced
– DOE Aluminum Spent Fuel (SRS, INL)• ~19MT & 13MT eq. respectively
• Evaluated Advanced & Research Reactor Specifications– Can Meet ASTM-C1462-00 (2013) for Advanced Reactors– Additional Laboratory Validation and Demonstration in Progress

Repurposing to Produce HALEU
• Scopes of Work – LR-230 Shipping Package License– Minor Flowsheet & Plant Modifications– NEPA – Record of Decision– Criticality & Safety Analysis– Natural Uranium (NU) Supply Contract– Staffing– Procedures & Training
• Decision Timing
• Could Produce ~2MT (19.75%) HALEU in Late FY22• Could Start Production ~1-1.5MT/yr in FY23• Could Produce HALEU to Specified Enrichment
