BWXT to build nuclear reactor for Army base
BWX Technologies (BWXT) will build a 20-megawatt nuclear microreactor at Fort Campbell under the Army’s Janus program. The project aims to provide resilient electricity to military bases and could lead to commercial applications. BWXT is one of five companies selected, with the Army allocating up to $2.2 billion over five years. The reactor is expected to be operational in the early 2030s.
