Abstract

DISPOSITIVO PARA LA LIMPIEZA DE LOS TUBOS DE GUIADO DE INSTRUMENTACION DE UN REACTOR NUCLEAR DE AGUA A PRESION. CONSTA DE MEDIOS (18, 19) PARA LA INYECCION DE AGUA DESMINERALIZADA A PRESION EN LOS TUBOS (5) DE GUIADO DE INSTRUMENTACION; D EMEDIOS (15, 20, 21, 22) PARA LA RECUPERACION DE LOS EFLUENTES RADIOACTIVOS, LOS CUALES SE COLOCAN SOBRE EL EXTREMO DE CADA UNO DE LOS TRAVESAÑOS (7) DEL FONDO DE LA CUBA (1) DEL REACTOR, SUCESIVAMENTE, SIN QUE SEA NECESARIO DESMONTAR LOS EQUIPOS INTERNOS INFERIORES (9, 40) DEL REACTOR. TODAS LAS OPERACIONES SE CONTROLAN DESDE LA PASARELA (17) DE CARGA DEL REACTOR, MEDIANTE LA UTILIZACION DE MEDIOS DE VISUALIZACION Y DE MEDIOS DE MANDO.
