Abstract

L'invention concerne un dispositif pouvant servir dans un réacteur nucléaire. Dans un appareil immergé dans du métal alcalin liquide et qui comporte des composants ayant des surfaces complémentaires de portée, l'un de ces composants ayant une surface de portée en acier inoxydable, un autre des composants possède une surface complémentaire de portée aluminée. L'appareil peut notamment s'appliquer aux dispositifs d'échange de chaleur dans des coeurs de réacteurs nucléaires surrégénérateurs à refroidissement par du métal alcalin liquide.The invention relates to a device suitable for use in a nuclear reactor. In an apparatus immersed in liquid alkali metal and which has components having complementary bearing surfaces, one of these components having a stainless steel bearing surface, another of the components has a complementary aluminized bearing surface. The apparatus can in particular be applied to heat exchange devices in the cores of breeder nuclear reactors cooled by liquid alkali metal.
