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.

In current salt-free flow sheets, U(IV) is used as a reductant in reductive partitioning of U-Pu. Because U(IV)-tri-n-butylphosphate (TBP) solvate has a low solubility in the organic phase, quantitative knowledge of U(IV) distribution behavior is important. Published data on U(IV) distribution between an aqueous nitric acid and 30% TBP/n-dodecane biphasic system at 298.15 K is analyzed, and an empirical model is reported. Performance of this model is compared with one earlier published model.
