Abstract
Perfeccionamientos en los aparatos para la limitación de movimiento de los elementos combustibles en un reactor nuclear, que comprende una placa de soporte de elementos de combustible separada del lado de descarga de refrigerante del núcleo del reactor del elemento de combustible y en el que los elementos de combustible comprenden una pluralidad de varillas de combustible cuyos ejes longitudinales son en general paralelos a la dirección del flujo de refrigeración del núcleo del reactor que comprende una guarnición extrema para el lado de descarga del refrigerante, y medios de torsión montados en el interior de dicha guarnición extrema susceptibles de apoyarse contra la placa de soporte del elemento de combustible y limitar el movimiento del mismo en la dirección del flujo del refrigerante del núcleo.
