# Small modular reactor technology development > Live situation record from CLSTR: https://clstr.news/situations/small-modular-reactor-technology-development > Updated: 2026-10-10T13:00:23.000Z. Sources: 14. Developments: 4. 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 is investing approximately 500 million PLN into the project, supported by approximately 400 million EUR from international partners including GE Vernova. By late 2026, the industry is seeing increased regulatory activity in the United States. Holtec International has advanced its nuclear construction permit application for the Palisades site in Michigan by submitting a Preliminary Safety Analysis Report to the 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 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 capital risks and construction timelines, with a potential site identified at the US Army’s Aberdeen Proving Ground in Maryland. ## Timeline ### 2026-10-10: US nuclear firms submit regulatory filings for small modular reactor projects Holtec International and Terrestrial Energy have submitted new reports to the US NRC to advance small modular reactor projects and propose streamlined regulatory pathways for nuclear deployment. 2 sources. https://clstr.news/cluster/us-nuclear-firms-submit-regulatory-filings-for-small-modular-reactor-projects ### 2026-10-03: Small modular reactor industry sees renewed momentum and federal backing The small modular reactor industry is seeing renewed momentum through federal funding and new construction, though companies like Oklo and NuScale face challenges with nonbinding backlogs and high costs. 2 sources. https://clstr.news/cluster/small-modular-reactor-industry-sees-renewed-momentum-and-federal-backing ### 2026-09-30: Polish entrepreneurs invest 500 million PLN in SMR project Leading Polish entrepreneurs are investing 500 million PLN into Synthos Green Energy to develop small modular reactors, while Westinghouse and Bechtel reach commercial terms for Poland's first large nuclear's. 7 sources. https://clstr.news/cluster/synthos-green-energy-secures-185-billion-pln-for-small-modular-reactor-projects ### 2026-09-29: Small modular reactors emerge as a growing nuclear energy trend Small modular reactors (SMRs) and microreactors are gaining international interest for their flexibility, with Russia's Akademik Lomonosov already in service and companies like NuScale and Oklo developing new S 3 sources. https://clstr.news/cluster/small-modular-reactors-emerge-as-a-growing-nuclear-energy-trend --- Cite as: Small modular reactor technology development.
