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 neutron shielding properties of ilmenite-magnetite (I-M) concrete are measured experimentally. The instantaneous relaxation length and thickness-dependent removal cross section of neutrons from a 252Cf source penetrating I-M concrete with and without a cadmium sheet are reported. An empirical formula is developed to calculate the thickness dependence of the removal cross section and the related coefficients are reported. The results illustrate the effectiveness of I-M concrete so far as its shielding properties are concerned. This material can be used to shield reactors, accelerators, X-ray installations, and radioactive sources used for commercial purposes.
