Hey you found my former employer.  Hanford is a fast flux reactor, and their waste is a little more onerous in the types of isotopes produced than the vanilla type of reactor found in most power generating facilites. The dirty little secret is that Hanford was a test site for a new generation of reactor that used a very different fuel cycle from those of your typical reacotrs owned by utilities.  I designed parts of that project and the original name was the Hanford Fast Flux Test Facility. People forget that nuclear fuel is recycled and very little of the original fuel goes to waste.  Vitrification has proven to work and is used in other industrial nations in the world.  The greatest generator of nuclear waste in this country is medicine and the isotopes of Cobalt are some of the most dangerous. By the way Cobalt isotopes used in medicine are transported without any restriction in all communities of the US. You may be driving down the highway and its in the truck next to you. Any time you go near a hospital you are mere feet from radioactive materials.
