Hanford is a federal facility going all the way back to the Manhatten Project.
Had a friend who worked for a contractor that was decommissioning the older buildings on the reservation. All the work was being done with remotely controlled robots because of the heavy, heavy radioactivity. Nothing came offsite, just simply broken down, consolidated, packaged, and stored. When the radiation would finally finish off a robot, it was just abandoned in place and another one sent in to pickup where it stopped. He ultimately moved onto more interesting work, but the work will go on for. centuries.
The only plus side is that because of the reservation’s very restricted access and human avoidance of radioactivity, Hanford is a massive wildlife preserve like Chernobyl has become.
I saw a program a while ago about how they built the dome for the Chernobyl reactor. They equipped the dome with robots that would, over time, disassemble the reactor.
I wonder if the government is monitoring wildlife which might eat radioactive vegetation there, then be hunted and eaten by humans?
