')A long deferred cleanup is now under way at 114 of the nation's nuclear facilities, which encompass an acreage equivalent to Rhode Island and Delaware combined. Many smaller sites, the easy ones, have been cleansed, but the big challenges remain. What's to be done with 52,000 tons (47,000 metric tons) of dangerously radioactive spent fuel from commercial and defense nuclear reactors? With 91 million gallons (345 million liters) of high-level waste left over from plutonium processing, scores of tons of plutonium, more than half a million tons of depleted uranium, millions of cubic feet of contaminated tools, metal scraps, clothing, oils, solvents, and other waste? And with some 265 million tons (240 million metric tons) of tailings from milling uranium ore—less than half stabilized—littering landscape.
In a decade real trains and trucks carrying high-level waste may head to Yucca Mountain, Nevada, the government's choice, and a controversial one, for a permanent repository. In addition to storing the waste, contaminated soil and groundwater must be treated and stabilized, nuclear reactors decommissioned, buildings demolished, some buried waste exhumed, sorted, and buried again because it wasn't buried right in the first place. The bill for all this will be staggering—perhaps 400 billion dollars over 75 years.”
Cute math, make the timeline long enough and every project no matter how meager will appear insurmountable. 400/75=5.33 billion per year, not even a drop in the bucket in the federal budget of 2.8 TRILLION dollars. Also nice of them to pick Rhode Island and Deleware, the two smallest states in the USA.
Come let us reason together, most of that waste you are referring to is weapons program waste left over from the cold war because the Feds didn't do anything to properly contain it the first time. For those zillions of gallons of acid liquid waste the first step is to neutralize it (lime or limestone does a fine job and is 'dirt cheap' lol), then you pour it out into drying pans like they use in Utah and let the sun evaporate off the liquid. Then you scrape off the residue, form it into solid blocks/drums of material and ship that. It takes a while to process so much stuff, but it not a technical challenge. The contaminated soils need to be remediated, expensive but not that expensive.
The 52,000 tons of spent nuclear fuel, that is about the size of a football field stacked 12 feet high. Sure doesn't sound so scary in those terms does it?
Those 'scores of tons of plutonium' are schedualed to be remanufactured into MOX fuel and used for energy production, if the feds ever get there thumb out of you know where. The three Pheonix reactors are able to run on 100% MOX cores and could together burn through it all in a decade or so.
Half a million tons of depleted Uranium. Oh the horror, Uranium which is LESS radioactive than it was when we dug it out of the ground, however can we handle that? How about we store it as metal oxide back in some old emptied Uranium mines? No no that's waaaaaay too simple and economic of a solution!
265 million tons of tailings, only half stabilized. Well DUH stabilize the second half, the job is already half done!
