U.S. Army Chooses BWXT Advanced Nuclear Reactor (BANR) for Janus Program

Key Terms

microreactor technical

A microreactor is a very small, factory-built nuclear power unit designed to produce electricity and heat for a single site or a small grid, much like a compact, highly engineered backup generator for towns, mines, ships or remote industrial sites. Investors care because microreactors promise faster construction, lower upfront cost and flexible deployment compared with large plants, while offering revenue potential alongside regulatory, safety and long-term maintenance risks.

triso fuel technical

Triso fuel is a type of nuclear fuel made of tiny ceramic kernels (often uranium) each wrapped in multiple protective coatings, creating hard, heat-resistant pellets like peas inside several shells. It matters to investors because that layered design improves safety, allows higher operating temperatures, and can reduce cooling needs and meltdown risk, which affects plant design, regulatory approval, operating costs and the commercial prospects of advanced reactors.

long-lead procurements technical

Purchases of items or services that have long manufacturing or delivery lead times and are critical to completing a capital project or operational rollout. Companies place these orders early—often with advance payments—to lock in delivery dates for things like custom equipment, major components or long-lead services; it’s like pre-ordering a custom item that takes many months to arrive. Investors watch long-lead procurements because they tie up cash, affect project timelines and expose the company to supply-chain, cost and timing risks that can change a project’s value or schedule.

LYNCHBURG, Va.--(BUSINESS WIRE)-- BWX Technologies, Inc. (NYSE: BWXT) announced today its selection to deploy its BWXT Advanced Nuclear Reactor (BANR) technology in support of the Janus program. Janus is a next-generation nuclear energy initiative led by the U.S. Army in partnership with the Defense Innovation Unit (DIU) to deliver reliable, resilient energy to support national defense missions and critical installations. The Janus Program launched in October 2025.

BWXT's BANR microreactor will be deployed at the Fort Campbell, Kentucky, U.S. Army installation.

The Army announced the first BANR will be deployed at Fort Campbell, Kentucky, located on the Kentucky-Tennessee border.

"The Janus Program is about transitioning from designs and experiments to reliable commercial hardware which secures our energy independence," said Dr. Jeff Waksman, Principal Deputy Assistant Secretary of the Army for Installations, Energy and Environment. "The Janus Program vendors were selected through a deeply rigorous evaluation on technical, financial, and organizational capabilities conducted by an All-Star panel of dozens of experts from across the nation. We look forward to working alongside each team as they proceed toward successfully completing the rigorous technical milestones we've agreed upon.”

“Our long-standing strengths in reactor engineering innovation, TRISO fuel development and advanced nuclear manufacturing are the foundation of our BANR technology,” said Rex D. Geveden, BWXT president and chief executive officer. “As we commence work on the Janus program, we are delivering the nation’s most credible and reliable path to deployable nuclear power. BANR is purpose built for mission success, and we are driving forward with the discipline, experience and proven capability that national security demands.”

BWXT will execute the Janus program under a phased contracting approach. The first phase includes working with the Army and DIU on final site selection within Fort Campbell, initiating nuclear regulatory processes with the Army and initiating TRISO fuel fabrication at existing BWXT facilities. Concurrently, BWXT will work with the customer and potential partners on establishing the operating company structure, characterizing the site, and preparing supply chains for long-lead procurements. BWXT is targeting groundbreaking for site construction in late 2028 with reactor operations commencing in the early 2030’s.

About BANR

BANR is a high temperature, gas-cooled nuclear reactor that utilizes TRISO, or TRi-structural ISOtropic, fuel. BANR is designed for critical infrastructure and can operate behind the meter or integrate with the grid, providing a safe, reliable and resilient energy solution. For Janus, a 20-megawatt electric version of BANR will be deployed.

Other features of the BANR technology:

• Compact footprint with option for multi-unit layout (one reactor sits on less than 5 acres)
• Power output is scale-able by deploying multiple reactors on the same site
• Leverages existing qualified materials and commercially available components
• Can operate as cogeneration (electricity + process heat) or all-electricity
• Four-year refueling cycle; produces 75-megawatts of thermal energy

BANR has received interest from multiple industries seeking a reliable, diversified source of energy, including Tata Chemicals Soda Ash LLC, which signed a letter of intent to explore deploying up to eight BANR units in Wyoming.

According to a U.S. Army announcement on the Janus selection process, the Army down selected five vendors to own, construct and operate nuclear microreactors at several military installations.
