Abstract

PROCEDIMIENTO PARA RECUPERAR MATERIAL MENUDO, POLVO Y PASTILLAS DE UO2 Y PRODUCIR PASTILLAS DE UO2 CON ALTA DENSIDAD DE SINTERIZADO. UN PROCEDIMIENTO PARA RECUPERAR MATERIALES MENUDOS DE UO2 QUE PRODUCE UNA PASTILLA DE ALTA DENSIDAD DE SINTERIZADO. EL MENUDO SE OXIDA EN UN HORNO A ALTA TEMPERATURA PARA OBTENER U3O8. LAS PARTICULAS DE U3O8 PROCEDENTES DEL HORNO DE OXIDACION SE HACEN REACCIONAR CON ACIDO NITRICO PARA OBTENER UNA SOLUCION DE NITRATO DE URANILO QUE CUMPLE LOS REQUISITOS DE CONCENTRACION Y DE ACIDO LIBRE DEL PROCEDIMIENTO DE PRECIPITACION ADU (DIURANATO AMONICO). SE LLEVA A CABO UN PROCEDIMIENTO DE PRECIPITACION ADUU (DIURANATO AMONICO) CONTROLADO EN DOS ETAPAS PARA OBTENER PARTICULAS DE DIURANATO AMONICO (ADU) CON UN TAMAÑO Y UNA MORFOLOGIA QUE CONDUCE A UN POLVO DE UO2 DE ALTA AREA SUPERFICIAL CON EXCELENTES CARACTERISTICAS CERAMICAS DE LA PASTILLA SINTERIZADA. TRAS UNA CALCINACION Y REDUCCION CON HIDROGENO A UO2, SE PASIVA EL POLVO DE UO2 DE ALTA AREA SUPERFICIAL.
