Abstract

L'invention concerne un agencement destiné à la fabrication de pastilles de combustible nucléaire dans une pluralité de composants de type machine disposés dans un domaine d'accès restreint défini par une pluralité de parois verticales et de planchers horizontaux, protégeant contre les radiations. Selon l'invention, les composants sont disposés au-dessous l'un de l'autre de façon à permettre au matériau nucléaire de s'écouler d'un composant à un autre composant sous l'influence de la gravité, et deboîtés latéralement les uns par rapport aux autres de façon à procurer un accès en partie superieure à chacun des composants sans gêne pour aucun des autres composants. Application aux centrales nucléaires.An arrangement for manufacturing nuclear fuel pellets in a plurality of machine-like components arranged in a restricted access area defined by a plurality of vertical walls and horizontal floors, shielding against radiation. According to the invention, the components are arranged below one another so as to allow nuclear material to flow from one component to another component under the influence of gravity, and laterally dislocated the components. with respect to each other so as to provide an upper part of access to each of the components without hindering any of the other components. Application to nuclear power plants.
