Abstract

Un marco guía de la barra de control que contiene una apilación auto-soporte de dos o más elementos encolumnados que definen un pasaje central. Los elementos encolumnados pueden incluir sistemas de acoplamientos que se acoplan en las superficies de contacto entre los elementos encolumnados adyacentes de dicha apilación. El marco guía de la barra de control es usado adecuadamente junto con un mecanismo de accionamiento de la barra de control (CRDM) operativamente conectado con al menos una barra de control y un núcleo del reactor nuclear en el que el CRDM mueve al menos una barra de control dentro y fuera del núcleo del reactor nuclear bajo la guía del marco guía de la barra de control. En otra realización, un marco guía de la barra de control contiene dos o más elementos encolumnados apilados que definen un pasaje central que tiene una sección eficaz constante como una función de la posición a lo largo del pasaje central. En otra realización, el marco guía de la barra de control incluye un elemento encolumnado extruído que brinda una guía continua de la barra de control.
