Abstract

Une pluralité d'aiguilles de combustible (17) remplies de matière fissile en tant que combustible sont mises en paquet et sont stockées dans un tube enveloppe (12). L'aiguille de combustible (17) est remplie avec une pluralité de pastilles de combustible dans un tube de gainage en acier inoxydable, forme un espace au niveau de la région de combustible, et constitue une région de plénum gazeux (16). Un assemblage combustible est constitué de manière à agencer des ouvertures (13) qui incluent l'extrémité inférieure de la région de plénum gazeux (16) et s'étendent vers le haut à partir de celle-ci dans les parois latérales du tube enveloppe (12). En formant les ouvertures (13) de manière à ce qu'elles ne se superposent pas avec la région de combustible, l'extrémité supérieure de la région de combustible où la température d'un tube de gainage de la tige de combustible est la plus élevée peut être refroidie par un fluide de refroidissement.A plurality of fuel pins (17) filled with fissile material as fuel are packaged and stored in a jacket tube (12). The fuel needle (17) is filled with a plurality of fuel pellets in a stainless steel cladding tube, forms a space at the fuel region, and constitutes a gas plenum region (16). A fuel assembly is formed to arrange openings (13) which include the lower end of the gas plenum region (16) and extend upwardly therefrom into the sidewalls of the casing tube ( 12). By forming the openings (13) so that they do not overlap with the fuel region, the upper end of the fuel region where the temperature of a fuel rod cladding tube is highest. high can be cooled by a coolant.
