Abstract
SI UNA BARRA DE ESTE TIPO TIENE EN SU PARTE INFERIOR, LA HACIA EL NUCLEO DEL REACTOR, UN ABSORBEDOR AG-IN-CD (5) Y EN SU PARTE SUPERIOR UN ABSORBEDOR B4C (6), EXISTE EL PELIGRO QUE PIEZAS DEL ABSORBEDOR B4C LLEGUEN A LA RANURA ENTRE EL ABSORBEDOR AG-IN-CD (5) Y EL TUBO DE REVESTIMIENTO (2). CUANDO LAS PIEZAS DEL ABSORBEDOR B4C SE HINCHAN SE PUEDEN PRODUCIR DAÑOS EN EL TUBO DE REVESTIMIENTO (2). CON EL FIN DE EVITAR ESTE TIPO DE DAÑOS SE PREVE QUE EL ABSORBEDOR AG-IN-CD (5) ESTE SEPARADO DEL ABSORBEDOR B4C MEDIANTE UN TAPON INTERMEDIO (7) CONECTADO FIJAMENTE CON EL TUBO DE REVESTIMIENTO (2) Y QUE ENTRE EL TAPON ENTREMEDIO (7) Y EL ABSORBEDOR AG-IN-CD (5) SE ENCUENTRE UN ESPACIO VACIO (8). PARA EVITAR QUE SE SOBREPASE LOCALMENTE LA POTENCIA DE LOS ELEMENTOS DE COMBUSTION CON ESTE TIPO DE ELEMENTOS DE CONTROL, SE PREVE QUE LOS ESPACIOS VACIOS DE BARRAS DE CONTROL VECINOS ESTEN DESPLAZADOS ENTRE SI VISTO EN DIRECCION AXIAL Y QUE LAS BARRAS DE CONTROL DE UN ELEMENTO DE CONTROL CON LA MISMA POSICION DE LOS ESPACIOS VACIOS SE ENCUENTREN EN POSICIONES DE NUCLEO SIMETRICAS.
