Small modular reactors (SMRs) and microreactors are emerging as a significant trend in nuclear energy production. These reactors are smaller and less powerful than conventional plants, typically capped at 300 megawatts, but offer greater flexibility and potential cost savings through mass production. While much of the technology is still in development, some applications are already operational. In Russia, the Akademik Lomonosov, a floating nuclear power plant in Pevek, has been in service since May 2020. In the private sector, companies like NuScale and Oklo are developing next-generation technologies, with commercial deployment expected in the early 2030s or late 2020s. In Poland, Synthos Green Energy (SGE) is advancing the commercialization of BWRX-300 technology through significant capital injections. A group of prominent Polish entrepreneurs—including Rafał Brzoska (InPost), Mati Staniszewski (ElevenLabs), Krzysztof Pawiński (Maspex), and Dariusz Gałęzewski (OSHEE)—is entrepreneurs is investing approximately 500 million PLN into the project. This domestic funding, combined with project, supported by approximately 400 million EUR (1.35 billion PLN) from international partners including a 100 million EUR contribution from GE Vernova, supports SGE’s efforts to deploy reactors across Poland, Central and Eastern Europe, and the United Kingdom. Investors have noted the necessity of stable, competitive energy to sustain industrial growth and emerging technologies such as artificial intelligence. Vernova. By late 2026, the SMR industry is seeing renewed momentum, supported by $900 million increased regulatory activity in federal funding reserved by the Trump administration, with $94 million already awarded. Companies like Oklo are targeting United States. Holtec International has advanced its nuclear construction permit application for the artificial intelligence sector Palisades site in Michigan by aiming to build plants near data centers to sell energy directly to AI providers. Meanwhile, NuScale Power continues to follow submitting a utility-based model. Despite this momentum, the industry continues Preliminary Safety Analysis Report to grapple with the transition from a construction-based model US Nuclear Regulatory Commission. This filing concerns two SMR-300 reactors, designated Pioneer 1 and Pioneer 2, intended to provide 680 megawatts of power. Additionally, Terrestrial Energy has proposed a more efficient manufacturing-based new regulatory model to the US Nuclear Regulatory Commission for its Thermal and Electric Facility. This bifurcated approach suggests that non-nuclear components, such as turbines, could be built under standard commercial codes while the nuclear module undergoes traditional licensing. This strategy aims to reduce costs. capital risks and construction timelines, with a potential site identified at the US Army’s Aberdeen Proving Ground in Maryland.
