# Can Nuclear Reactors Hit the Road? Small modular reactors are bringing the promise of nuclear revolution closer. - **Source:** [Nature](https://brifing.si/source/4d850c3b-dd79-4024-bc91-db2571889199) - **Published:** 2026-08-26 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/bab8dd1c-f31d-4751-9f01-01026ab57bbd ## A New Era in Nuclear Energy Small modular reactors (SMRs) offer lower-cost and faster-to-build solutions compared to traditional nuclear plants. Their compact size allows transportation to remote locations. 46 companies are working to commercialize this technology by 2030. These reactors have the potential to revolutionize energy production with their innovative design and scalability. ## Advantages of Portability SMRs' biggest advantage is not requiring large installation sites. They provide ideal solutions for areas with weak energy infrastructure. Companies like Oklo Inc. are testing these reactors in military bases and disaster zones. Their portability enables rapid response to energy crises and flexible deployment options. ## Waste Management Challenges Nuclear waste remains a significant challenge for SMRs. However, next-gen reactors can reduce waste volume by up to 90% compared to conventional plants. Planned projects in Utah showcase innovative waste storage solutions. Experts emphasize these technologies must meet stringent safety standards for widespread adoption. ## Regulations and Safety Nuclear energy policies play crucial roles in SMR adoption. The US Department of Energy allocated $7 billion for small reactors in 2023. Licensing processes can be lengthy due to safety concerns. Canada and UK are working to streamline regulations to accelerate deployment of these innovative energy solutions. ## Economic Considerations SMRs cost $1-3 billion per unit, significantly less than traditional plants. Mass production could further reduce costs through economies of scale. DOE projections indicate the global SMR market could exceed $300 billion by 2035. Investors are showing increasing interest in this emerging sector as energy demands grow worldwide. ## Environmental Impact SMRs produce 95% less carbon emissions than coal plants. They could play vital roles in achieving UN sustainable energy goals. Concerns remain about nuclear waste and water usage. Stanford University researchers are conducting lifecycle analyses to better understand their environmental footprint. ## Global Competition The US, China, and Russia lead the race in SMR technology. China plans to deploy 20 floating nuclear reactors by 2025. Russia's Akademik Lomonosov operates as the world's first floating nuclear plant. The European Union supports SMR development through its Clean Energy Package initiatives. ## Pivotal Moment for Energy Future Small modular reactors could serve as critical bridges in the clean energy transition. They uniquely address both energy security and climate goals simultaneously. Experts project SMRs might supply 12% of global electricity by 2050. This technology appears poised to shape the energy sector's trajectory for the next three decades. ## Sources covering this story - https://www.nature.com/articles/d41586-026-02510-8 — --- _Summary written by Brifing from the original reporting.
