Abstract

LOS TUBOS DE GUIA (6) PARA ELEMENTOS DE CONTROL DE ALEACIONES DE CIRCONIO (ZIRKALOY 2 Y ZIRKALOY 4) EN REACTORES NUCLEARES DE AGUA A PRESION MUESTRAN AL COMIENZO DE SU APLICACION EN LOS NUCLEOS DE LOS REACTORES, UN FUERTE CRECIMIENTO EN SENTIDO AXIAL INDUCIDO POR LOS RAYOS. EL FUERTE CRECIMIENTO DE LOS TUBOS EN EL INICIO SE COMPENSA MEDIANTE LA CONTRACCION PROPIA DE LOS TUBOS. CON ESTE FIN, SE PROPONEN TUBOS DE GUIA (6) QUE PRESENTAN TENSIONES INTERNAS QUE SE REDUCEN A CAUSA DE LA APORTACION DE ENERGIA CONDICIONADA POR LA RADIACION MEDIANTE UNA CONTRACCION DEL TUBO. PARA LA PRODUCCION SE FABRICAN, EN PRIMER LUGAR, TUBOS DE GUIA (6) DEMASIADO CORTOS QUE, A CONTINUACION, SE ALARGAN EN UNA ULTIMA FASE DE FABRICACION EN, AL MENOS, UN 0,3 POR CIENTO PARA DARLES SU DIMENSION FINAL. PARA LA PROLONGACION DEL TUBO, SE PROPONE, SEGUN LA INVENCION, ESPECIALMENTE EL ESTIRADO EN UN ENDEREZADOR.
