Abstract

Envoltura de núcleo de reactor nuclear con una pluralidad de chapas horizontales que rodean y se adaptan estrechamente a la forma del núcleo, caracterizada por el hecho de que las chapas horizontales se encuentran dispuestas entre una pluralidad de pantallas térmicas superpuestas de forma general cilíndrica, que rodean el núcleo y que están ligeramente separadas del mismo, y deque están previstos medios para ejercer de manera elástica una fuerza de comprensión sobre el sistema de pantallas térmicas de chapas horizontales apiladas.
