A documentation-driven reconstruction of a NuScale SMR 17×17 fuel assembly, based on publicly available FSAR documentation, developed from HMP/HTP spacer grids toward the complete assembly and compared with a standard Westinghouse 17×17 PWR fuel assembly.
A PWR fuel assembly is more than a repeated structure of rods and grids. It is a compact system of geometry, materials, neutron behavior, coolant flow, and operational discipline. This article explores how 3D reconstruction can make that hidden reactor logic visible.
