Abstract

METODO PARA ENCAPSULAR, EN UN CEMENTO, UN RESIDUO LIQUIDO RADIOACTIVO.COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, SE SOMETE EL RESIDUO LIQUIDO RADIOACTIVO A UN PROCESO DE MEZCLADO, EN UN MEZCLADOR DE GRAN POTENCIA, PARA OBTENER UN PRODUCTO HOMOGENEO CON UN VOLUMEN PREDETERMINADO; SEGUNDA, SE AN/ADE UNA PASTA ACUOSA DE CEMENTO AL HOMOGENEIZADO ANTERIOR Y SE SOMETE DE NUEVO LA PASTA A UN MEZCLADO DE GRAN POTENCIA DURANTE EL TIEMPO SUFICIENTE PARA ELIMINAR EL AGENTE DE RETARDO DE LA SUPERFICIE DE HIDRATACION DEL CEMENTO; Y POR ULTIMO, SE MANTIENE LA AGITACION HASTA SUPERAR LAS REACCIONES DE RETARDO, PARA PRODUCIR UNA MEZCLA TIXOTROPICA QUE FRAGUE RAPIDAMENTE, ENCAPSULANDO EN SU INTERIOR EL PRODUCTO RADIOACTIVO.
