Researchers at the Idaho National Laboratory have demonstrated realistic full-core predictive modeling of a commercial nuclear reactor over multiple years of use. The simulation platform is named MOOSE (Multiphysics Object Oriented Simulation Environment).

Two new AP1000 nuclear power reactors are under construction at the Virgil C. Summer Nuclear Generating Station in Fairfield County, South Carolina. Along with two new units at the Vogtle Electric Generating Plant in Georgia, these are the first new nuclear units built in the United States in the past three decades.
