NOVELTY - The method involves containing a component (60) contaminated with a radioactive contaminant (64) in a chamber (12). An air flow (14) is generated through the chamber, where the air flow outgoing from the chamber is in fluid communication with a filter (26). The contaminant is cleaned from the component with a dry ice blasting stream that is used to remove the contaminant from the component such that the removed contaminant is transported by the air flow to the filter. The air flow is filtered using the filter to entrap the removed contaminant in the filter.    USE - Method for cleaning a radioactive material contamination of a component e.g. duct, pipe, vessel, container, tank, power tool, and electrical component i.e. motor, in reactors such as power reactors, research or non-power reactors, naval and marine-type reactors, plutonium production reactors, and marine fuel cells, of a nuclear power plant (all claimed). Can also be used for nuclear research facilities, nuclear propulsion facilities, and government facilities such as department of energy (DOE) facilities, naval facilities and nuclear submarines.    ADVANTAGE - The dry ice used for the blasting process sublimates into gaseous carbon dioxide during cleaning process such that incremental contaminated cleaning media or residue is not generated during decontamination of the component, and damage to the component being cleaned and decontaminated is prevented or avoided by using the dry ice that is non-corrosive, non-abrasive and environmentally neutral so as to enable cleaning of electrical components without compromising electrical function.    DETAILED DESCRIPTION - The filter is a high efficiency particulate air (HEPA) filter. An INDEPENDENT CLAIM is also included for a system for cleaning a component contaminated with a radioactive material.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a system for removing radioactive contamination from a component.
