trans- + uran(ium) + -ic.


  • It includes low-level waste and debris that is classified as transuranic waste because it is contaminated with plutonium.

    The Seattle Times

  • Department of Energy held a briefing in Greene County about the "transuranic" radioactive waste shipments that will start in July - Philadelphia's Source For Breaking News, Weather, Traffic and Sports

  • Overall, there are roughly 400,000 cubic feet of plutonium-contaminated [ "transuranic"] waste housed at the facility, much of it generated by LANL's own nuclear weapons activities.

    Indybay newswire

  • Lab Director Charles McMillan said the barrels contain transuranic waste — gloves, toolboxes, tools — and other items that may have been contaminated through contact with radioactive materials.

  • By comparison, there is an alternative called "Thorium", which produces much smaller quantities of transuranic elements, and these are readily separated in the liquid reactors being proposed.

    Linda Bergthold: Fukushima Nuclear Reactors in Japan: A Report From Tokyo

  • This incident has nothing to do with the leaking tanks of transuranic waste involved in the Hanford Site cleanup, other than being located within 50 miles of the place.

    WhooPPSS! (Jack Bog's Blog)

  • Originally designated a second generation sun, with elements up to the transuranic, Arrutan patently did not conform to that classification.

    Cattle Town

  • Used fuel is about 95% uranium-238 but it also contains up to 1% uranium-235 that has not fissioned, about 1% plutonium and 3% fission products, which are highly radioactive, with other transuranic elements formed in the reactor.

    Nuclear fuel cycle

  • The radiotoxicity of these wastes would be relatively short-lived compared with the actinides (long-lived alpha-emitting transuranic isotopes) from a fission reactor.

    Nuclear fusion power

  • However, although fusion generates no radioactive fission products or transuranic elements, and the unburned gases can be treated on site, there would a short-term radioactive waste problem due to activation products.
