Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA LA LIMPIEZA DE PLANTAS NUCLEARES CONTAMINADAS RADIACTIVAMENTE MEDIANTE DESPRENDIMIENTO DE CAPAS SUPERFICIALES POR CHORREO. CONSISTE EN CHORREAR LAS PIEZAS A LIMPIAR MEDIANTE UN CHORRO DE AGUA DESMINERALIZADA A PRESION, QUE CONTIENE UN ABRASIVO EN GRANO Y QUE MEZCLA, EVENTUALMENTE, AIRE. LA MEZCLA SALIENTE DE AGUA, ABRASIVO Y PARTICULAS DESPRENDIDAS, POTENCIALMENTE RADIACTIVAS, SE SEPARA EN UNA FASE ACUOSA Y UNA FASE DE FANGO. ESTA FASE SE SECA Y SE SEPARA LA MASA SECA EN ABRASIVO Y PARTICULAS QUE TENGAN UN DIAMETRO INFERIOR AL DE LOS GRANOS DE ABRASIVO. LOS GRANOS DE ABRASIVO LIMPIOS SE REUTILIZAN REENVIANDOLOS AL CHORRO DE AGUA A PRESION. LAS PARTICULAS SEPARADAS SE ELIMINAN. LA FASE ACUOSA PUEDE DEJARSE EVAPORAR. EL VAPOR DE AGUA SEPARADO AL SECARSE EL FANGO PUEDE RECONDUCIRSE A LA FASE ACUOSA. LA MEZCLA PUEDE SEPARARSE POR SEDIMENTACION. SE PRESENTA TAMBIEN UN DISPOSITIVO PARA LA REALIZACION PRACTICA.
