Operator error is often used as a simple explanation for failure. In complex technical systems, it should not close the analysis. It should open a deeper question: what made the action possible, likely, or difficult to recover from?
A documentation-driven reconstruction of a NuScale SMR reactor pressure vessel, based on publicly available FSAR documentation and developed from internal volume and system topology toward upper internals, CRA and ICI penetrations, CRDM housing interfaces, feedwater geometry, and containment vessel constraints.
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.
Human factors engineering is not about blaming operators. It is about designing technical systems, procedures, interfaces, training and organizational conditions around how people actually perceive, decide, communicate and act.
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.
Nuclear systems are not designed around optimism. They are designed around credible failure, conservative margins, physical feedback, redundancy, and verified safety functions. Safety is not treated as a promise, but as a documented property of the system.
In my experience, some of the kindest, most principled people I’ve known were engineers. Their empathy showed through responsibility, precision, and care, not through public emotion.

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.
A documentation-driven 3D reconstruction of the HI-STORM 100S dry cask system, focused on confinement, shielding, passive cooling, criticality control and the spatial logic behind spent fuel storage.
