NuScale Power vs. Nano Nuclear: Which Nuclear Stock Has an Edge Now?
Read MoreHide Full Article
Key Takeaways
NuScale advances SMR projects with major partners and a landmark TVA agreement for 6 gigawatts.
Nano Nuclear secures a 10-year INL pact to accelerate KRONOS and LOKI microreactor development.
NNE strengthens North American presence with licensing progress in the United States and Canada.
NuScale Power (SMR - Free Report) and Nano Nuclear Energy (NNE - Free Report) are major players in the small modular reactor (SMR - Free Report) and microreactor market, aiming to deliver next-gen clean nuclear energy solutions. While NuScale Power works on developing SMRs for large-scale energy projects, Nano Nuclear is developing microreactors that aim to provide clean, portable and scalable nuclear power.
Per Fortune Business Insight report, the global SMR market was valued at $5.81 billion in 2024 and is projected to reach $8.37 billion by 2032, expanding at a CAGR of 4.98% from 2025 to 2032. Both Nuscale Power and Nano Nuclear Energy are likely to gain from the massive growth opportunity as their technologies are poised to play a key role in meeting the rising global demand for safe, reliable and clean nuclear energy.
So, SMR or NNE — Which of these nuclear stocks has the greater upside potential? Let’s find out.
The Case for SMR Stock
NuScale Power is benefiting from the advancements in SMR technology. The company’s expanding partner base, which includes tech giants and financial institutions, positions the company as a key player in the future of sustainable, carbon-free energy.
The company’s expanding SMR portfolio has been a key catalyst. The company made significant strides in the manufacturing and commercialization of its SMR technology, including progress with key partners such as Doosan Interability and ENTRA1 Energy, which further solidified its position in the market.
NuScale Power recently announced its support for ENTRA1 Energy’s historic agreement with the Tennessee Valley Authority. This deal will deploy up to 6 gigawatts of its NRC-approved SMR technology, making it the largest SMR program in U.S. history. This initiative aims to deliver carbon-free, baseload electricity to meet the growing demand from key sectors, including AI, data centers and semiconductor manufacturing.
The Case for NNE Stock
Nano Nuclear Energy is strategically positioned to capitalize on the growing demand for clean, reliable and zero-emission energy solutions, particularly in the advanced nuclear sector.
Building on this momentum, NNE recently announced a 10-year Cooperative Research and Development Agreement with Idaho National Laboratory (“INL”) to advance its microreactor technologies, including the KRONOS MMR and LOKI MMR systems. This collaboration will use INL’s expertise in reactor design, materials testing, regulatory support, and commercialization to speed up the development, licensing, and deployment of NNE’s clean, modular nuclear energy solutions.
NNE is also advancing KRONOS licensing in both the United States and Canada, with collaborations like the University of Illinois Urbana-Champaign project and Canadian Nuclear Laboratories, positioning it as a leader in the North American microreactor market.
Price Performance and Valuation of SMR and NNE
In the year-to-date period, NuScale Power and NNE’s shares have appreciated 91.4% and 26.3%, respectively. NuScale Power benefits from advancements in SMR technology and its growing partnerships with tech giants and financial institutions.
Despite an expanding portfolio and clientele, Nano Nuclear is facing a pre-revenue phase as it concentrates on advancing research and development for its microreactors. This suggests that near-term revenue prospects remain limited. Moreover, similar to other nuclear startups, the company faces lengthy regulatory approval processes and significant development expenses before reaching commercial deployment.
