BWX Technologies, Inc. operates primarily through two segments: Government Operations and Commercial Operations. The Government Operations segment is the sole manufacturer of naval nuclear reactors for U.S. Navy submarines and aircraft carriers, and it also supplies specialized nuclear materials and environmental restoration services to federal agencies. The Commercial Operations segment designs and manufactures commercial nuclear steam generators, heat exchangers, pressure vessels, and other auxiliary equipment, while also providing nuclear fuel and lifecycle management services for the global nuclear power industry. Additionally, the company produces medical radioisotopes and radiopharmaceuticals. BWXT's distinctive competitive position stems from its highly specialized licenses, facilities, and technical expertise required to manufacture sensitive nuclear hardware and handle highly enriched uranium.
