Abstract

A method is described for disposal of radioactive liquid waste materials. The wastes are mixed with clays and fluxes to form a ceramic slip and disposed in a thermally insulated container in a layer. The temperature of the layer rises due to conversion of the energy of radioactivity to heat boillng off the liquid to fomn a dry mass. The dry mass is then covered with thermal insulation, and the mass is self-sintered into a leach-resistant ceramic cake by further conversion of the energy of radioactivity to heat.

Method for utilizing decay heat from radioactive nuclear wastes

Patent Busey, H.M.

Management of radioactive heat-producing waste material while safely utilizing the heat thereof is accomplished by encapsulating the wastes after a cooling period, transporting the capsules to a facility including a plurality of vertically disposed storage tubes, lowering the capsules as they arrive at the facility into the storage tubes, cooling the storage tubes by circulating a gas thereover, employing the so heated gas to obtain an economically beneficial result, and continually adding waste capsules to the facility as they arrive thereat over a substantial period of time.

Improved method for solidifying liquid radioactive wastes

Patent Berreth, J.R.

The quantity of nitrous oxides produced during the solidification of liquid radioactive wastes containing nitrates and nitrites can be substantially reduced by the addition to the wastes of a stoichiometric amount of urea which, upon heating, destroys the nitrates and nitrites, liberating nontoxic N$sub 2$, CO$sub 2$ and NH$sub 3$.

METHOD OF REDUCING AQUEOUS RADIOACTIVE NUCLEAR WASTES TO SOLID FORM

Patent Loeding, J.W. ; Jonke, A.A.

A method is given for conventing a waste solution of aluminum nitrate containing a minor amount of ruthenium to solid form. The solution is evaporated and calcined in a fluidized bed, which is fluidized by a mixture of carbon monoxide and nitrogen, whereby volatility of the ruthenium is inhibited.
METHOD OF TREATING RADIOACTIVE WASTES

Patent Milliken, T.H. Jr. ; Krause, J.H. ; Donovan, J.J.

A process is described for separation of radioactive cesium, strontium, and ruthenium from nitrate waste liquor solutions to a degree whereby such solutions may be discarded or further processed in normal patterns with simplified techniques. The waste solution is first treated to form the normally adsorbable bulk ions other than Cs, Sr, and Ru into a sol having no appreciable affinity for adsorption on ion exchange materials. Additives suitable for formation of the sol include oxides or hydrous oxides of Al, Ti, Fe, Th, or Zr, metal organic compounds of the same metals such as Al isopropylate, or oxycarbonates.
