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.

Modeling was carried out on vapor-liquid equilibria of nitric acid containing highly concentrated fission product nitrates to simulate the evaporation characteristics of a reprocessing plant high-level liquid waste (HLLW) concentrator. Results obtained with the model verified its reliability for prediction of vaporliquid equilibria of nitric acid containing highly concentrated nitrates. The results compared well with experimental data obtained with a pilot plant for HLLW concentration (capacity of 40 dm3).
