Abstract

Assemblage combustible destiné à un réacteur nucléaire modéré et refroidi par eau sous pression. Il comprend un combustible nucléaire, sous forme de multiples aiguilles étroitement serrées, à axes longitudinaux parallèles, dont chacune comprend une gaine tubulaire portant le combustible, la surface de la gaine présente au moins une saillie ou ailette longitudinale, assembles à une aiguille voisine pour former un assemblage solidaire. Applicable notamment aux surrégénérateurs.Fuel assembly for a moderate nuclear reactor cooled by pressurized water. It comprises a nuclear fuel, in the form of multiple tightly tight needles, with parallel longitudinal axes, each of which comprises a tubular cladding carrying the fuel, the surface of the cladding having at least one longitudinal projection or fin, assembled with a neighboring needle to form a united assembly. Applicable in particular to breeder reactors.
