Abstract

Perfeccionamientos introducidos en las envolturas para la delimitación del flujo refrigerante en los reactores nucleares a sus zonas nucleares; siguiendo dichas envolturas por lo general a la forma de la delimitación del núcleo reactor definida por los conjuntos combustibles en el reactor, comprendiendo al reactor además una camisa para el núcleo reactor dispuesta entorno de la envoltura para lindar el refrigerante entrante por el exterior de la camisa del núcleo reactor hasta que el refrigerante sea dirigido para pasar en dirección predeterminada a través de los conjuntos combustibles dentro de la delimitación del refrigerante formada por la envoltura, caracterizados por un zuncho sustancialmente cilíndrico, situado en el interior de la camisa del núcleo reactor y exterior a la delimitación del refrigerante, y por una pluralidad de elementos soportes espaciados, que se extienden desde la delimitación del refrigerante hasta el zuncho.
