Japanese company to support Uzbekistan's nuclear-powered data center project
Tokyo's Muroosystems signed a memorandum with Uzatom to help build a ~50 MW data center next to Uzbekistan's first nuclear power plant in Jizzakh, powered by a small modular reactor.
A project to build a nuclear-powered data center in Uzbekistan is being supported by a Japanese company. The project is tied to the country's first nuclear power plant.
Japan's role
Tokyo-based Muroosystems signed a memorandum of understanding on peaceful nuclear cooperation with Uzbekistan's Atomic Energy Agency (Uzatom) on 20 December 2025. Under the document, the Japanese side provides safety assessments, regulatory support, technical consulting and engineering services. Technical work is carried out through the company's German subsidiary, Nukem.
What the data center will be
The plan calls for a data center of about 50 megawatts on the site of the Jizzakh nuclear power plant, drawing power from one small modular RITM-200N reactor. Developers say it could be the world's first data center powered entirely by a small modular reactor. The domestic partner is the Ministry of Digital Technologies.
The nuclear power plant
The plant is being built in the Forish district of the Jizzakh region by Russia's Rosatom (with Atomstroyexport as main contractor). The project envisages two large VVER-1000 units (1,000 MW each) and two small RITM-200N reactors — four units in total, with a combined capacity of about 2.1 gigawatts. First concrete was poured in March 2026; the first small reactor is expected online in 2029, the large units in 2033 and 2035.
«This collaboration in Central Asia goes far beyond individual projects — it represents a long-term partnership for the safe and transparent development of nuclear energy», said Thomas Seipolt, head of Nukem.
