Volume reduction of radioactive ion exchange resins for disposal
Abstract
Abstract ION EXCHANGE RESINS WHICH HAVE BECOME CONTAMINATED WITH RADIOACTIVATE MATERIALS, ARE REDUCED IN VOLUME FOR PRUPOSES OF DISPOSAL BY TREATING THE CONTAMINATED RESINS WITH CERTAIN SOLVENTS HAVING A DIELECTRIC CONSTANT OF ABOUT 45 OR LOWER. SOLVENTS, SUCH AS, METHANOL, ETHANOL AND ACETONE MAY BE USED TO REDUCE THE VOLUME OF THE CONTAMINATED RESINS PRIOR TO STORAGE AND/PR DISPOSAL. THE METHOD OF THIS INVENTION AS APPLIED TO DISPOSAL OF RADIOACTIVELY CONTAMINATED ION EXCHANGE RESINS REDUCES THE SPACE REQUIRED FOR STORAGE AND/OR BURIAL OR BULK QUANTITIES OF THIS TYPE OF RADIOACTIVE WASTE MATERIAL, PROVIDES A SELF-SEALING MEDIUM WITHIN THE STORAGE CONTAINERS TO PREVENT SMALL LEAKS WHEN THE CONTAINERS ARE STORED IN AN AQUEOUS MEDIUM, AND PROMOTES BURNING OF THE RESIN IN CASES WHERE INCINERATION IS DESIRABLE.
