Abstract

Conjunto combustible fácilmente desmontable para reactor nuclear, que incluye un haz de barras combustibles paralelas cuya separación es mantenida por distanciadores transversales con relación a las barras y tubos de sostén del ensamblaje que sustituyen a algunas barras combustibles, siendo estos tubos de sostén de una longitud superior a las barras y estando fijados por cada extremo a una placa que asegura la rigidez del ensamblaje combustible, estando asegurada su fijación a una, por lo menos, de las placas de extremo, por medio de casquillos cilíndricos que incluyen dispositivos de unión complementarios de dispositivos correspondientes llevados por los extremos de los tubos y provistos de un perfil para la introducción de un útil que permite hacer girar el casquillo alrededor de su eje en un sentido y en el otro, para su fijación al tubo con aprieto del tubo contra la placa de extremo en el sentido longitudinal y para desolidarizar el tubo y la placa, caracterizado por el hecho de que los casquillos están dispuestos en el interior de aberturas coaxiales al tubo y a los casquillos que atraviesan las placas de extremo de parte a parte a la altura de los tubos de sostén apoyados sobre las placas por medio de un resalto, y porque incluyen una parte deformable que permite el bloqueo de la fijación del tubo en rotación por expansión de esta parte deformable en alojamientos previstos en las placas de extremo, y porque los extremos de los tubos de sostén están constituidos por ensanches con superficie externa prismática para su introducción en alojamientos de forma correspondiente dispuestos en la cara de apoyo de la placa de extremo.
