Abstract
a. L'invention concerne un revêtement écarteur pour l'appui des blocs hexagonaux d'éléments combustibles dun réacteur surrégénérateur rapide refroidi au sodium. b. On pose sur chaque face du bloc, côte à côte, deux pièces d'écartement en matières alternativement différentes de même longueur et de même largeur par rapport à la face du bloc. c. Les pièces d'écartement s'appliquent, quand on assemble les blocs, de façon qu'une pièce d'une matiere soit en contact avec une pièce d'une autre matière ce qui permet de tirer parti des propriétés favorables à la friction de matières différentes. En outre ce procédé permet d'économiser le cobalt.
