Greater Than Class C Waste

Greater than Class C (GTCC) wastes contain concentrations of radionuclides greater than Class C limits established in 10 CFR Part 61. These wastes, as mentioned earlier, cannot be disposed of as LLRW but must go to a geological repository. GTCC waste comes primarily from decontamination and decommissioning of nuclear power plants. Nonutility generators include manufacturers of sealed sources used as measuring devices. GTCC waste volume is projected to expand during the next twenty years as more nuclear plants are decommissioned.
