Hanford Tank Waste Processing

• Over 200,000 m3 of radioactive waste stored in underground tanks from plutonium production from 1943-1989

• ~90 % of the volume will be designated low-activity waste (LAW)

▪ Filtered, ion exchange to remove 137Cs

▪ Vitrified and disposed of on site

• AP-107 and AP-105 first waste to be processed

• High-level waste vitrified later

Operations• No visual – operations based on temp/flowrate etc.

• Bubbler change out on LAW

• Melter change out when failed (>5 years life, 6 months to change out)

• Feed sequence for LAW

▪ AP-107 tank supernatant (followed by contents of other DSTs)

▪ TSCR (filtration/Cs removal by IX)

▪ Product to AP-106 – feed forward to WTP LAW CRV tank

▪ Add any recycle – Analysis – add GFC – Make glass

• Tank Sequence

▪ AP-107, AP-105 ….
