NuScale Power is exploring industrial heat applications for its small modular reactors, with a 12-module plant potentially delivering 3 gigawatts of thermal energy and cutting chemical plant CO2 emissions by 80%-90%. The company is developing steam compression technology to expand industrial applications.

However, commercial adoption remains uncertain as NuScale must demonstrate systems at scale, secure customers, and arrange financing. Other nuclear developers like NANO Nuclear Energy and Oklo are pursuing similar strategies.

Oklo Inc. (OKLO) achieved first criticality at its Groves-1 Isotope Test Reactor in Texas in August 2026, following DOE startup authorization in July. The facility completed substantial construction in 229 days and secured enriched ytterbium-176 for cancer-treatment isotope production.

The company plans to leverage this experience for future isotope facilities while its Idaho lab may generate earlier revenues. However, OKLO shares have declined over 80% in the past year and carry a Zacks Rank #4 (Sell) rating.

The article analyzes four nuclear reactor stocks and their potential valuations by 2031. Oklo, NuScale Power, and Nano Nuclear Energy face significant execution risks with current stock prices appearing to price in substantial post-2031 growth. BWX Technologies, a more established supplier with existing revenue, carries less commercialization risk but trades at a premium valuation with limited upside room.
