Abstract
UN METODO Y APARATO PARA ELECTROLITICAMENTE QUITAR IONES METALICOS RADIACTIVOS DE UNA SOLUCION DE DESCONTAMINACION PARA REGENERAR LA SOLUCION Y PREPARAR LOS IONES PARA ARREGLO SON DESCUBIERTOS EN ELLO. AL MENOS LA PARTE CATODICA (69) DEL ELECTRODO (45) USADO EN LA ELECTROLISIS ES FORMADO DE UN COMBUSTIBLE, TAL COMO UNA BASE SEMI-FLUIDIZADA DE PARTICULAS DE GRAFITO. EN EL METODO DEL INVENTO, LA SOLUCION DE DESCONTAMINACION ES PASADA EN CONTACTO INTIMO CON LAS PARTICULAS DE GRAFITO QUE FORMAN LA PARTE CATODICA (69) DEL ELECTRODO (45) CUANDO UN POTENCIAL ELECTRICO ES APLICADO AL ELECTRODO (45). COMO RESULTADO DEL POTENCIAL ELECTRICO, LOS IONES METALICOS SON SEPARADOS DEL QUELATO EN LA SOLUCION DE DESCONTAMINACION Y DEPOSITADOS HACIA LAS PARTICULAS DE GRAFITO DE LA PARTE CATODICA (69) DEL ELECTRODO (45). DESPUES DE QUE EL ELECTRODO (45) LLEGA A SER PASADO, ES INCINERADO EN ORDEN A REDUCIR EL VOLUMEN DE LA CENIZA RADIOACTIVA RESULTANTE. LOS GASES PRODUCIDOS DE LA INCINERACION SON DEPURADOS CON UN LIQUIDO DEPURADOR PARA QUITAR LAS PARTICULAS RADIACTIVAS DE ELLO. EL LIQUIDO DEPURADOR CONTAMINADO ES A LA VUELTA USADO PARA FORMAR UNA SUSTANCIA DE CEMENTACION O LECHADA QUE ACAPSULAR LA CENIZA RADIACTIVA.
