要約
(EN) A tubular body according to the present invention has a SiC tube reinforced by SiC fiber as a base material and a metal layer formed inside the base material. Also, in a structure of the tubular body, a rare earth silicate layer is formed on a side of an outer surface of the base material. According to this, a tubular body is provided which relates to a fuel placed in a core part in a reactor for using water as a coolant and prevents generation of hydrogen due to a reaction with water in case of an accident. The tubular body is suitable for a fuel cladding tube having a structure with high reliability relative to radioactive nuclide containment at the time of a normal operation and transfer.
(FR) La présente invention concerne un corps tubulaire qui est obtenu en utilisant un tube de SiC renforcé par des fibres de SiC en tant que matériau de base, et en formant une couche métallique sur l'intérieur du matériau de base. Le corps tubulaire est une structure obtenue en formant une couche de silicate de terre rare sur le côté de la surface extérieure du matériau de base. Ainsi, il est possible de fournir un corps tubulaire qui est approprié pour être utilisé en tant que tube de gainage de combustible ayant une structure qui est très fiable, non seulement pendant le fonctionnement normal, mais également pendant le transport, lors du confinement des radionucléides, étant donné que, même dans le cas d'un accident impliquant le carburant contenu dans le cœur de réacteur d'un réacteur nucléaire qui utilise l'eau comme liquide de refroidissement, la production d'hydrogène provoquée par une réaction avec l'eau est supprimée.
