FIELD: physics, atomic power.SUBSTANCE: invention relates to nuclear reactor fuel assemblies, primarily fast neutron reactors. A fuel assembly housing having a longitudinal axis (X) comprises a first (4) and a second (6) tubular segment made of metal and forming longitudinal ends of the assembly housing. A frame (8) made of metal connects the first (4) and second (6) segments, wherein the frame (8) is meshed. A ceramic internal tubular structure (10) is placed between the first (4) and second (6) segments inside the frame (6).EFFECT: stability of the fuel assembly in both standard and emergency operating mode of the reactor.22 cl, 1 tbl, 8 dwg |
