NUCLEAR POWER TRAINING UNIT (NPTU) NRF IDAHO FALLS ID

The Nuclear Power Training Unit (NPTU) NRF Idaho Falls, Idaho, has played a critical role in the training of U.S. Navy nuclear propulsion personnel since its establishment in the 1950s. Located at the Naval Reactors Facility (NRF) within the Idaho National Laboratory, NPTU Idaho Falls provided hands-on training using land-based prototypes of naval nuclear reactors, including models based on submarine and aircraft carrier reactor designs. Thousands of officers and enlisted personnel underwent rigorous instruction and practical experience at the site, ensuring a highly skilled workforce for the Navy's nuclear-powered fleet. The NPTU at Idaho Falls was instrumental in supporting the Navy’s nuclear program for decades, until the decommissioning of its training prototypes, with training now consolidated at other NPTU locations.
