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.

Geochemical interactions of actinide colloids are of vital importance to understanding the migration of actinides in natural aquifer systems. Much effort has gone into quantifying the migration of colloids and, subsequently, to applying these quantities to hydrodynamic and geochemical modeling. An overview of recent progress in the investigation of migration behavior of actinide colloids in natural aquifer systems is presented. The impact of pseudocolloid generation on actinide migration is also discussed and illustrated with the results obtained in recent studies.
