If you really want to read some cool things about Hanford, check out the DOE's cleanup page, and the IEER reports about cleaning up the "canyons".
And remember that they built those now-leaking tanks in the 1940's and '50's. There's also some great accident reports about the "accountability" tanks at Sellafield.
Great reminder that nuclear waste represents a multi decade, even multi century/millenium challenge in some cases. This makes me very wary of a federal government with no plans for dealing with the piling up waste now that yucca mtn (an admittedly problematic project) has been cancelled. The feds are raising money for this but will it be enougb? Of course not!
