Abstract

PROCEDIMIENTO PARA EL AJUSTE ELECTROQUIMICO DE LA ETAPA DE OXIDACION PLUTONIO (VI), EN SOLUCIONES DE ACIDO NITRICO. COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, SE PREPARA UNA CELULA ELECTROLITICA (1) QUE CONTIENE UNA CAVIDAD ANODICA (5) Y UNA CAVIDAD CATODICA (4) SEPARADAS POR UN DIAFRAGMA (45); SEGUNDA, EN LA CAVIDAD ANODICA SE INTRODUCE LA SOLUCION DE PARTIDA DE U >+/PU >+ NITRATO/NHO Y SE BOMBEA CONTINUAMENTE EN CIRCUITO CERRADO POR MEDIO DE UNA BOMBA (21) Y DE UNA VALVULA DE TRES PISOS (22), DURANTE EL PROCESO ELECTROLITICO; TERCERA, EN LA CAVIDAD CATODICA SE INTRODUCE NHO 2-3 MOLAR Y SE BOMBEA CONTINUAMENTE EN CIRCUITO CERRADO MEDIANTE LA BOMBA (31), DURANTE EL PROCESO ELECTROLITICO; Y POR ULTIMO, SE ESTABLECE UNA TENSION ENTRE EL ANODO (5) Y EL CATODO (4) DE 3 VOLTIOS.
