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.

Assessment of the RELAP5/MOD2 code on the basis of experiments performed in a pressurized water reactor simulator, the LOBI/MOD2 facility at the European Research Center of Ispra in Italy is reported. In particular, significant experience gained in the analysis of two small-break loss-of-coolant accidents (tests A2-81 and A1-83), a steam generator tube rupture (test BL-21), a natural circulation (test A2-77A), and four transients (tests A2-90, BT-00, BT-01, and BT-03) is discussed.
