Central Asia’s Nuclear Push: Uzbekistan Starts Construction as Kazakhstan Plans at Least Three Plants
Uzbekistan has poured concrete for its first nuclear power plant, while Kazakhstan has signed a $16.5 billion agreement for a two-reactor facility near Lake Balkhash and approved a site for a second plant. Kazakhstan's long-term strategy calls for at least three nuclear power plants by 2050, with a fourth possible. Both governments are presenting nuclear power as a way to meet rapidly growing electricity demand and strengthen energy security. Yet the projects are advancing at different speeds and are reviving questions over water use, cross-border safety, financing, and long-term reliance on Russian technology and credit. Uzbekistan Moves Into Construction On June 4, 2026, Uzbek President Shavkat Mirziyoyev and Russian President Vladimir Putin launched construction by video link. Rafael Mariano Grossi, director general of the International Atomic Energy Agency, also took part. The first nuclear-grade concrete was poured overnight from June 4 to June 5 for the foundation slab of the first RITM-200N small modular reactor unit in the Forish district of the Jizzakh region. Uzatom subsequently classified the site as a nuclear power plant under construction. The facility is one plant with four planned reactor units: two large VVER-1000 units and two smaller RITM-200N units, each rated at 55 MW. Together, they would provide more than 2.1 GW of installed capacity. The present configuration is the latest version of a project that began with a 2017 peaceful-use agreement and a 2018 plan for two large reactors. In 2024, the focus shifted to six small reactors, before the design changed again in 2025 to the mixed large-and-small format now under construction. Uzbek and Russian projections put annual generation at about 17 billion kWh, or roughly 15% of future national demand. The current schedule envisages the first small unit reaching criticality in late 2029, with the large reactors expected to be commissioned in 2033 and 2035, although Uzatom has said final dates depend on outstanding contract arrangements. The project's stated base price is $9.5 billion, and Tashkent is seeking loans for most of the cost. Those financing terms, along with the final allocation of construction and operating risk, remain central to the project's viability. Water and Cross-Border Concerns The plant will stand near Lake Tuzkon in the Aydar-Arnasay lake system, about 40 kilometers from Kazakhstan's border. That proximity has made what is formally an Uzbek project a regional issue. Residents and environmental advocates in southern Kazakhstan have raised concerns about accident preparedness, radioactive waste, and possible pressure on already stressed water systems. Aiman Tleulesova, national coordinator of the Central Asian Regional Water Network, has argued that reactor cooling could require greater discharges into Lake Tuzkon and additional withdrawals linked to the Syr Darya system. In her assessment, that could intensify competition for irrigation water in Kazakhstan's Turkestan and Kyzylorda regions. These are concerns raised by specialists and campaigners, rather than established measurements of the completed plant's impact, but they require a quantified response because water scarcity is already a recurring regional problem. Uzbekistan held public hearings on the environmental impact assessment in...
