Volume Reduction of Radioactive Waste Resulting from Decontamination of Surplus Nuclear Facilities
Numerous surplus nuclear facilities have been ear-marked for decontamination and decommissioning. The decontamination of these facilities will produce significant quantities of radioactively contaminated waste requiring disposal. These wastes will include wet ion exchange resins, liquid wastes, and dry combustible materials. A fluidized bed concept for calcining liquid wastes and incinerating combustible wastes in the same process vessel is being developed by Energy Incorporated in Idaho Falls, Idaho, in a partnership with Newport News Industrial Corporation of Newport New Virginia. A licensing topical report has been filed with the NRC(1) and an application for patent has been submitted. The initial benefit derived from such a waste volume reduction system is a reduced space commitment to waste storage at the affected waste management facility. The expense of space at such a facility is increasing because the storage techniques are being upgraded to allow for ease of retrieval. Subsequent benefits of reduced waste volumes will include reduced retrieval costs, reduced shipping costs, and a reduced impact at the final permanent storage site.
