Abstract

La presente se refiere a un separador elástico para elementos combustibles nucleares formado por dos rejillas, unidas ambas rígidamente mediante pernos, y que contienen lugares de emplazamiento de barras combustibles y de los tubos guías y de instrumentacion. En la cara externa de este conjunto se pueden colocar o no patines externos completando una estructura rígida. Los lugares de emplazamiento de barras combustibles, en las rejillas, contienen apoyos fijos destinados a posicionar las barras combustibles y nervios que sirven de apoyo y localizacion a resortes longitudinales, con los cuales queda completado un separador elástico. El desplazamiento de las barras combustibles es restringido por los resortes elásticos longitudinales. Una aplicacion de la presente es su utilizacion en los elementos combustibles para reactores nucleares modulares.
