STAINLESS STEEL PROCESS WASTES: I. REMOVAL OF ALLOY METALS FROM WASTE SOLUTIONS BY MERCURY CATHODE ELECTROLYSIS
A method is proposed for the separation of the metal ions iron, nickel, and chromium from the fission products in wastes resulting from the chemical processing to recover uranium from reactor fuels clad or alloyed with stainless steel. A separation of the alloy metals and the fission products was accomplished in the laboratory by electrolysia of the alloy metals over a mercury cathode. The standard reduction potentials at the mercury cathode of the major long-lived fission products are such that they are difficult to reduce electrolytically in acid solution. The removal of alloy metal ions from solution by mercury cathode electrolysis permits the alloy constituents and the fission products to be treated as separate wastes. The alloy constituents may be converted to a solid and stored in low integrity containers without danger of self-heating from fission product decay. The fission product waste can be reduced to a very small volume for storage and recovery of valuable fission products or converted to a solid for permanent disposal. (auth)
