Abstract

Cette structure comporte un matelas de quelques couches de boulets de graphite protecteur et, monté amovible verticalement dans l'axe de l'orifice central à travers le réflecteur et le béton, un bloc de graphite foré selon son axe pour permettre le déchargement des boulets combustibles et des boulets protecteurs. Application aux réacteurs nucléaires à haute température.
