  • Patent number: 4443269
    Abstract: Disclosed is a system and method for cleaning radioactively contaminated articles, including tools and like items of hardware. The system includes a cleaning chamber for receiving and sealing therein the contaminated articles, a high pressure spray gun disposed within the cleaning chamber for spraying the contaminated articles with a clean solvent to dislodge and dissolve the contaminants, and a system for decontaminating the solvent for reuse. The cleaning chamber includes a drain having the capacity to remove contaminated solvent at a rate at least as great as that at which the solvent is sprayed into the chamber, such that substantially no contaminated solvent collects in the cleaning chamber.

  • Patent number: 4235600
    Abstract: Garments are deposited in a cleaning drum and the drum is agitated during a wash cycle. A dry cleaning solvent is continuously added to the drum during the wash cycle and continuously removed from the drum during the wash cycle to flush the radioactive particulate material separated from the garments into a sump. The solvent is pumped from the sump for addition to the drum during the wash cycle and the pumped solvent is filtered to remove substantially all of the radioactive particulate material suspended in the solvent.The apparatus for decontaminating the radioactive garments comprises a sump for supporting a dry cleaning solvent. A drum for supporting the radioactively contaminated garments during a wash cycle which separates the radioactive particulate material from the garments means are provided for continuously pumping the dry cleaning solvent from the sump to the drum and for continuously removing the solvent and separated particulate material from the drum into the sump.
