An activist just unlocked BWXT's dormant SMR design. The timing is the story.

BWX Technologies has agreed to license its small modular reactor design following sustained pressure from activist investor Ananym Capital Management, which argued that the IP from the shelved mPower programme was sitting idle on the balance sheet while the commercial nuclear market revived around it. BWXT was one of the US's first serious SMR developers in the early 2010s before the project stalled, and the company pivoted to high-margin defence work, including $1.4 billion in 2026 naval nuclear propulsion contracts and a $1.5 billion NNSA enrichment deal. Licensing, rather than self-developing, lets BWXT participate in the data-centre-driven SMR demand wave without diverting capital from defence. The second-order effect: if a defence-anchored nuclear incumbent starts crystallising value from dormant reactor IP under activist pressure, expect similar pressure on other diversified industrials holding advanced nuclear assets quietly. This is a template, not a one-off.
