Absorbing Neutrons, Shaping Time
Boron and gadolinium do not produce energy in a reactor. They help define the conditions under which energy can be produced safely, predictably, and over time.
From Pressure Vessel to Integrated System
In the NuScale SMR integral PWR configuration, the reactor pressure vessel is not only a pressure boundary around the core. Based on publicly available FSAR documentation, it can be read as a compact system architecture where core geometry, steam generation, pressurizer volume, natural circulation and passive safety functions are closely connected.
When Documentation Becomes Space
A documentation-driven reconstruction of a NuScale SMR core, based on publicly available FSAR documentation and focused on the spatial relationship between fuel assemblies, control rod assemblies, in-core instrumentation, upper core structures, and the wider logic of compact reactor architecture.
The Reconstruction Began at the Grid
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.
