An FSAR-based 3D reconstruction of the NuScale SMR containment vessel, focusing on the documented CNV configuration, access openings, support lugs, refueling flange, DHRS nozzles, and simplified ECCS trip/reset actuator penetrations.
The blue glow may be the spectacle, but the bridge above it shows responsibility. A personal reflection on nuclear work, procedure and the quiet human presence above complex systems.
Nuclear safety culture is not a slogan, a poster or a formal statement on a wall. It is the way an organization thinks, communicates, questions, learns and responds when safety matters.
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.
A natural-draft cooling tower is easy to recognize from a distance. Understanding it is something else. This article follows the reconstruction of a cooling tower beyond its familiar silhouette, toward the internal logic of water distribution, airflow, evaporation, access, and heat rejection.
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.
