Neither of the two commercial prospects BWX Technologies $BWXT has named for its BANR microreactor is a data center. 1) Prodigy Clean Energy, a Montreal-based developer of factory-built nuclear plants: Two BANRs for a transportable pilot plant in Belledune, New Brunswick, built mainly at $BWXT’s Ontario plants and running in the early 2030s. New Brunswick’s government signed a letter of intent (LOI) to buy the power. $BWXT and Prodigy are still negotiating a definitive agreement, and the release provides no dollar value. 2) Tata Chemicals Soda Ash: A Wyoming soda ash producer that signed an LOI to explore deploying up to eight BANRs. $BWXT also markets BANR to data centers. However, I found no data center contract, customer, LOI, or revenue in any $BWXT press release from January 2025 through October 2026, in the FY2025 10-K, or in the 2026 10-Qs. $BWXT’s own mentions stop at a product page saying BANR can provide “clean electricity for municipalities, data centers and campuses,” and slides 11 and 25 from its Investor Day on September 29, 2026, which list “AI/data center demand” as a driver of nuclear demand in general. I didn’t hear the phrase “data center” mentioned once during Investor Day, and slide 49 lists data centers in the third phase of $BWXT’s microreactor plan. CEO Rex Geveden said at Investor Day that “the incremental demand from AI right now is 60 GW” and “winning at AI means winning at power, and winning at power probably means having a nuclear solution.” If he’s right, $BWXT benefits by supplying components, fuel, and services to more reactors, not by selling microreactors to data centers. Advanced Reactor Design and Engineering, the product line that includes Project Pele (its prototype microreactor for the Pentagon) and $BWXT’s other microreactor programs, brought in $203.8M in 2024 and $147.1M in 2025, then $52.6M in H1 2026, down from $69.8M a year earlier. At 3.0% of $BWXT’s $1,761.8M of H1 2026 revenue, microreactors are still a small, early business.
