The Rise of Small Modular Reactors (SMRs) in the Clean Energy Revolution
As the world urgently pivots towards deep decarbonization, nuclear energy is stepping into a more prominent role, with small modular reactors (SMRs) emerging as a key solution. These innovative energy systems possess the capacity to provide continuous, emission-free baseload power, meeting the surging clean-energy demand driven by the rapid growth of AI-powered data centers, electrification, and industrial reshoring. Governments and corporations are actively seeking reliable, carbon-free energy sources, and SMRs present a scalable pathway to satisfy increasing energy needs while remaining steadfast to climate objectives.
Advantages of Small Modular Reactors
The compact and modular designs of SMRs confer significant advantages over traditional nuclear plants. Their smaller footprint allows for deployment closer to end-users, effectively reducing the need for extensive transmission and distribution infrastructure. This not only curtails energy losses but also lowers associated costs. The flexible siting of SMRs, bolstered by standardized manufacturing processes and enhanced safety features, creates a transformative potential for the future of energy systems.
Pioneers in Nuclear Innovation: Nano Nuclear Energy and NuScale Power
Nano Nuclear Energy (NNE) and NuScale Power Corporation are at the forefront of this nuclear renaissance, poised to address the escalating demand for clean energy through their advanced, compact reactor technologies. They offer scalable solutions that enable faster deployment, supporting energy-intensive data centers and facilitating grid expansion by minimizing transmission needs. This positions them as integral players in the quest for cleaner, more resilient electricity.
NNE, particularly, stands to gain from the global rise in demand for dependable baseload power and a growing interest in small nuclear reactors. Its microreactor technology is ideally suited to meet the energy requirements of data centers and the broader trend toward electrification—underpinned by favorable government policies supporting advanced nuclear initiatives. With their scalable and mobile reactor designs, NNE is not just focused on immediate requirements but is also well-positioned for long-term growth.
NuScale Power, recognized as the first company to receive approval from the U.S. Nuclear Regulatory Commission (NRC) for its small modular reactor design, maintains a strong competitive edge in next-gen nuclear technology. As electricity demands escalate due to factors like AI workloads, industrial electrification, and overarching decarbonization goals, the case for scalable SMRs strengthens, enhancing NuScale Power’s prospects for sustainable growth.
Early Stages of Commercial Deployment
Both Nano Nuclear Energy and NuScale Power are currently in the pre-revenue phase, underscoring their emerging role in the next wave of nuclear technology. With no commercial reactors operational yet, these companies are concentrating their efforts on design validation, regulatory approvals, and forming critical industry collaborations.
Earnings and Future Forecasts
Looking ahead, the Zacks Consensus Estimate for Nano Nuclear Energy’s earnings per share in 2025 indicates a significant decline of 207.69%. Similarly, NuScale Power’s earnings per share for the same year foresees a more staggering decrease of 490.48%. These projections highlight the challenges both companies face as they navigate the nascent stages of commercialization in the nuclear sector.
Commitment to Research and Development
Both companies place a strong emphasis on research and development to advance their next-generation reactor designs and safety features. Their R&D initiatives strive to hasten regulatory approvals and improve efficiency, gearing up for future commercial deployment. In the first nine months of 2025, Nano Nuclear Energy has invested nearly $11.3 million in R&D, while NuScale Power has allocated around $32 million during the same timeframe. This sustained investment reflects their commitment to innovating and refining their technologies.
Regulatory Milestones
Recent regulatory developments indicate significant progress for these companies. In May 2025, the NRC approved NuScale Power’s enhanced 77 MWe reactor design, allowing utilities to rely on this standardized model when applying for combined licenses to construct and operate new nuclear plants. In April 2025, Nano Nuclear Energy obtained a crucial NRC approval for its KRONOS micro modular reactor’s fuel qualification methodology, paving the way for prototype deployment. The company further solidified its developmental trajectory through collaboration with the University of Illinois Urbana-Champaign, where the first KRONOS research unit will be hosted.
Market Performance Insights
In the past year, shares of Nano Nuclear Energy have increased by 11.7%, showcasing a positive trajectory against NuScale Power’s decline of 35.8%. This performance underscores the distinct market positions and investor sentiments surrounding these companies as they strive to carve out their place in the evolving nuclear landscape.
A Close Look at NNE and NuScale Power
As both Nano Nuclear Energy and NuScale Power work towards providing clean energy solutions, their efforts are critical in the global endeavor to reduce emissions. Despite being in the early stages, it appears that Nano Nuclear Energy, currently carrying a Zacks Rank of #3 (Hold), holds a strategic advantage over NuScale Power, which has a Zacks Rank of #5 (Strong Sell).
