Uzbekistan builds its first nuclear plant with Russia's Rosatom

Uzbekistan builds its first nuclear plant with Russia's Rosatom

Built World

A Central Asian state with no nuclear history breaks ground on a mixed large-reactor and small-reactor plant designed by Russia's state atomic company.

Today: Putin and Mirziyoyev launch construction of first power unit

Overview

Uzbekistan has never run a nuclear reactor. On June 4, 2026, by video link from an economic forum in St. Petersburg, the presidents of Russia and Uzbekistan started construction of the country's first one.

The plant pairs two large Russian VVER-1000 reactors with two pocket-sized 55-megawatt units. Russia's state nuclear company, Rosatom, is building it. The project gives a fast-growing economy steady baseload power and extends Moscow's nuclear export business deep into Central Asia, even under Western sanctions.

Why it matters

A country of 37 million people is locking in decades of electricity supply, and tying that supply to Russian technology, fuel, and engineers.

Historical Context

3 moments from history that rhyme with this story — and how they unfolded.

April 2018

Akkuyu nuclear plant, Turkey (2018–present)

Rosatom began building Turkey's first nuclear plant, four large VVER-1200 reactors, under a deal where Russia owns and operates the plant. After 2022, sanctions disrupted payments and equipment shipments, delaying the first unit.

Then

Construction slipped behind schedule as banking and supply problems mounted.

Now

The project showed both Rosatom's reach and how sanctions can stall its foreign builds without stopping them.

Why this matters now

Akkuyu is the clearest recent example of a Rosatom export project meeting sanctions friction, the same risk hanging over Uzbekistan's plant.

November 2020

Astravets nuclear plant, Belarus (2020)

Belarus started up its first nuclear reactor, built by Rosatom, despite objections from neighboring Lithuania over safety and location near its capital.

Then

The plant came online and added major baseload power, though early technical faults forced shutdowns.

Now

It tied Belarus's grid and fuel supply tightly to Russia for decades.

Why this matters now

Astravets shows what a first-ever Rosatom-built plant means for a country: new power, but lasting dependence on Moscow for fuel and parts.

1995 to 2011

Bushehr nuclear plant, Iran (1995–2011)

Russia took over Iran's stalled nuclear plant in 1995 and finally connected it to the grid in 2011, after repeated delays over funding, design changes, and politics.

Then

Bushehr took roughly 16 years from Russian takeover to grid connection.

Now

It became a working plant but a byword for how long Russian nuclear exports can take.

Why this matters now

Bushehr is a reminder that first-of-a-kind Rosatom projects often run far past their original timelines, a caution for Uzbekistan's 2029 target.
