Abstract

SE DA A CONOCER UN PROCEDIMIENTO PARA LA PRUEBA, REPARACION O INTERCAMBIO DE CONDUCTOS (2) DE UN FONDO (3) DE RECIPIENTE A PRESION DE REACTOR, DONDE LA CARGA RADIACTIVA SE REDUCE DE FORMA CONSIDERABLE A TRAVES DE SONDAS (4) DE UNA INSTRUMENTACION NUCLEAR INTERNA O FUERA DEL RECIPIENTE A PRESION DEL REACTOR. PARA ELLO SE UTILIZAN RECIPIENTES (6,7,8,9) BLINDADOS INDIVIDUALES EN EL RECIPIENTE (1) A PRESION DEL REACTOR. UN RECIPIENTE (9) BLINDADO ESTA REALIZADO CON POZOS (17), EN LOS QUE SE INTRODUCEN CASSETTES (19) RELLENAS CON AGUA. EN LA PLACA (10) DEL FONDO DE LOS RECIPIENTES (6,7,8) BLINDADOS RESTANTES Y EN LOS FONDOS (20) DE LAS CASSETTES SE INSERTAN TUBOS (15) PARA LA RECEPCION DE LAS SONDAS (4). DESPUES DE LA ELIMINACION DE UNA CASSETTES (19) SE INTRODUCE EN EL POZO (17) UN SOPORTE (22) PARA LA HERRAMIENTA DE MECANIZADO.
