Abstract

SEPARADOR DE DESECHOS. CONSTA DE: UN RECINTO HUECO (46) TENIENDO EL RECINTO HUECO UN PAR DE PAREDES (48, 50); UNA CAMARA DE CAPTURA Y RETENCION DE DESECHOS (54); ELEMENTOS QUE DEFINEN UNA ABERTURA EN LA CAMARA (54) A TRAVES DE LA PARED (50); ELEMENTOS DE RETENCION DE DESECHOS (76) DISPUESTOS EN LA CAMARA (54); ELEMENTOS DE DISTRIBUCION DE CAUDAL (84) DENTRO DE LA CAMARA (54). EL INVENTO SE REFIERE GENERALMENTE A REACTORES NUCLEARES Y A UN SEPARADOR MONTADO EN EL INYECTOR INFERIOR DE UN CONJUNTO DE COMBUSTIBLE PARA CAPTURAR Y RETENER DESECHOS QUE QUEDEN EN EL REACTOR DESPUES DE OPERACIONES DE MONTAJE, REPARACION Y/O SUSTITUCION.
