About this Unit
Nuclear Power Training Unit (NPTU) Ballston Spa, NY, was established in the 1950s as part of the U.S. Navy’s nuclear propulsion program, under the direction of Admiral Hyman G. Rickover. The facility, located at the Kenneth A. Kesselring Site, has served as a critical training center for naval personnel operating the Navy’s nuclear-powered ships and submarines. Over the decades, NPTU Ballston Spa has provided hands-on training with land-based nuclear reactor prototypes, ensuring the Navy maintains a highly skilled corps of nuclear-trained sailors. The site continues to play a vital role in supporting national defense by preparing sailors for duty in the Navy’s nuclear fleet.
Historical Facts
•
Naval Prototype Training Unit (NPTU) Ballston Spa: The NPTU in Ballston Spa, NY, is one of the U.S. Navy’s premier sites for training sailors to operate nuclear-powered submarines and aircraft carriers.
•
Location and Legacy: The site is located at the Kenneth A. Kesselring Site, named after Rear Admiral Kenneth A. Kesselring, an early leader in Naval nuclear propulsion.
•
Origins in World War II: The Kesselring Site originally served as the location for General Electric’s research on jet engines during World War II, before being repurposed for nuclear training.
•
Prototype Reactors: The facility has housed several operational land-based nuclear reactor prototypes, including models closely replicating those used on submarines and carriers.
•
Student Throughput: Thousands of Navy nuclear operators (officers and enlisted) train at NPTU Ballston Spa annually, making it a critical node in the Navy's nuclear pipeline.
•
Role in Women’s Integration: NPTU Ballston Spa has played a role in training some of the first female sailors assigned to nuclear-powered submarines as the Navy expanded gender integration.
•
Strict Security: Due to the sensitive nature of its mission and technology, the facility is highly secure and access is tightly controlled.
•
Public-Private Partnership: The site is operated in partnership with civilian contractors, most notably Bechtel Marine Propulsion Corporation, supporting the Navy’s Nuclear Propulsion Program.
•
Community Involvement: NPTU Ballston Spa is a major employer in the Saratoga County area and works closely with the local community, including emergency preparedness and outreach.
•
Unique Training Environment: Students at NPTU Ballston Spa spend months in rigorous hands-on reactor training, including “underway” drills that simulate at-sea operations, often under demanding conditions and hours.
