The River Protection Project at Hanford is working on cleaning up a huge amount of radioactive waste stored in underground tanks. The plan is to retrieve the waste, separate it into high-level and low-activity fractions, remove harmful substances, turn it into glass, and dispose of it safely. They have made progress in designing a plant to treat the waste, and they are also finding ways to speed up the process by treating some waste differently. They are testing new methods like bulk vitrification to help with the cleanup.
