The human factor in licensing and operating the next generation of nuclear plants
As human factors specialists working at the intersection of human performance and nuclear operations, we are witnessing one of the nuclear sector’s most significant transitions in decades. The emergence of small modular reactors, microreactors, and other advanced designs is reshaping the industry’s landscape. Digital instrumentation and controls, passive safety systems, and increased automation are creating opportunities for greater safety margins and more flexible operation. These same features also fundamentally redefine what it means to “operate” a nuclear plant. Interactions among human roles, automation, and passive systems shape how people maintain awareness, exercise judgment, and intervene when necessary. These developments affect both operational realities and the regulatory foundations on which nuclear safety is built.

The fuel handling sequence at the Fast Flux Test Reactor in Richland, Washington, utilizes several computer-aided fuel handling machines, a fuel conditioning station, and fuel storage vessels. Each system is designed to appropriately maintain the sodium-wetted fuel in an argon atmosphere (to prevent sodium reaction with moisture and oxygen) and control the temperature of the fuel assembly within the specified limits. Refueling experience has been used to decrease plant refueling time. Equipment utilization has exceeded original estimates because of changes in the irradiation program. Most of the fuel handling equipment has operated reliably, but with aging, some equipment upgrades are in progress or are being planned.
