Chemical reprocessing at Hanford would generate 22, 000 tonnes of high-level waste and 500, 000 tonnes of low-level waste.

The high-level waste would then be enclosed in glass canisters and buried deep underground while the low-level waste was stored above ground in special secure facilities.

This would typically be a manufacturer, distributor, licensed radioactive waste broker, or a licensed low-level radioactive waste disposal facility.

Tokyo Electric is now grappling with where to put the stuff, even dumping thousands of tons of less-radioactive water into the Pacific to make room for it in a reservoir for low-level waste.
