Won't China take it?
Why would they? Contaminated gloves, clothing, safety glasses, tools, material, cleaning supplies and equipment that has touched radioactives are useless once contaminated. Spent fuel is reprocessed for other purposes.
One of my former jobs provided metering equipment, and two of the customers were the Savannah River project and the Fluor/Mox Piketon project. Once equipment was installed and contacted radioactives, it ran until it was dead or out of calibration, then discarded as waste. No re-use. Of course, Piketon was ALT-F4'd just as we shipped, but Savannah River took a lot of equipment over the years and used it.

Yeah, Chyna will take it. It's what they'll do with it that matters. They'll either feed the waste to thier pheasant class or refine it and send it back as payloads on ICBMs.
