The New Reactors — SMR & Advanced Nuclear
The first commercial SMRs ship 2027-2029. The stocks are pricing that already.
Conventional reactors take 10-15 years to build, cost $10-20B, and routinely run over budget. Small Modular Reactors (SMRs) are the proposed answer: factory-built reactors of 50-300 MW, shipped to site, identical units in series. None have shipped commercial power yet . NuScale was first NRC-certified (2023), then lost its UAMPS deployment, then signed a Standard Power deal in 2024 for two data-center sites. Oklo is the most ambitious (fast reactor, sodium-cooled, designed for hyperscaler private use). BWXT is the boring profitable name that already builds nuclear components for the US Navy and operates as fuel fabricator for SMRs. Highly speculative group — but the eventual winner is a multi-bagger .
If even one SMR design hits commercial deployment at promised cost ($65-80/MWh), it reshapes the entire grid build-out. Hyperscalers want behind-the-meter reactors for AI campuses. Industrial customers (steel, cement, fertilizer) want them for process heat.
3 names on the watchlist
Fast reactor "powerhouse" model — pre-revenue moonshot
Sodium-cooled fast reactor developer targeting 15-75 MW "Aurora powerhouse" units — designed to run on recycled nuclear fuel (its second business). Pre-revenue: Q1 2026 net loss $33M. Sam Altman is chairman, which both helps (network) and hurts (governance concerns). First commercial Aurora targeting 2027-2028 at Idaho National Lab site.
Only NRC-certified SMR design in the US — light-water, modular
Light-water-reactor SMR — the conservative, regulatory-blessed approach. The only design the NRC has fully certified for commercial deployment in the US . Lost the UAMPS Idaho project in 2023, which crushed the stock — but signed Standard Power for 24 modules across two data-center sites and Romania. Closest to "real" of any SMR name. Still pre-revenue from commercial deployment.
US Navy nuclear-component monopoly + SMR fuel fabrication
Old, profitable, government-funded. BWXT is the sole supplier of nuclear propulsion to the US Navy — a contracted, multi-decade business. Building HALEU fuel facilities. Won contract to make TRISO fuel for X-energy. Less explosive upside than Oklo, but actual profits, actual revenue, and bipartisan political support. The "boring uncle" of the SMR thesis — and the one professional managers actually own.
