Document Type and Number:
Japanese Patent JP2947485
Kind Code:
B2
Abstract:
The invention relates to a nuclear fuel assembly, and to a method, for optimizing the utilization of nuclear fuel. The nuclear fuel assembly is composed of an initial set of axial fuel modules (34) stacked end-to-end and releasably interconnected to structurally integrate them as an axially modular fuel assembly (32). After use of the latter in a reactor core, its axial fuel modules (34) are released for separation from each other and unstacked, whereupon incompletely burnt upper and lower end modules (34A, 34B) can be reclaimed for subsequent use, together with fresh fuel modules substituted for spent ones of the initial set, in a reconstituted axially modular fuel assembly.
