ABSTRACT:
A modular fuel assembly has a plurality of axially stacked subassemblies. The stacked subassemblies includes upper and lower subassemblies which incorporate top and bottom nozzles, and a plurality of intermediate subassemblies disposed between the upper and lower subassemblies. Each subassembly includes a plurality of elongated guide thimble segments, a plurality of fuel rod segments and a pair of support grids mounted to the guide thimble segments and supporting the fuel rod segments. The guide thimble segments of the upper and lower subassemblies are releasably mounted to the respective top and bottom nozzles thereof. The guide thimble segments are interlocked together to form a plurality of elongated guide thimbles extending between and together with the top and bottom nozzles defining a structural skeleton of the modular fuel assembly with the support grids of the respective subassemblies disposed in axially spaced relation relative to one another along the guide thimbles and the fuel rod segments of the respective adjacent subassemblies disposed in axially aligned end-to-end interfitted relation with each other to form a plurality of elongated fuel rods of the modular fuel assembly.
