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.

6 days ago: 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.

How could it take so long? Not really that large?

Nine years from agreement to groundbreaking is actually normal for a first nuclear plant — Uzbekistan had no nuclear infrastructure at all, and the project was redesigned twice, resetting the clock each time.

Why it matters: The repeated design pivots (large reactors → six SMRs → two large plus two small) aren't just delays; they reflect a country still deciding what it actually wants from nuclear power.

  • Uzbekistan started from zero: no nuclear law, no regulator, no trained workforce. Uzatom, the agency now running the project, had to be created from scratch before serious planning could begin.
  • The design changed at least twice — original plan was two VVER-1200 units (2017–2018); scrapped in 2024 for six RITM-200N SMRs; then revised again in September 2025 to two VVER-1000s plus two SMRs. Each redesign meant new site assessments, contracts, and approvals.
  • Comparable Rosatom projects confirm this pace: Turkey's Akkuyu took 8 years from agreement to first concrete (2010–2018); Egypt's El Dabaa took 7 years (2015–2022). Bangladesh's Rooppur was faster (4 years) partly because Soviet engineers had surveyed the site in the 1960s.
  • At 2,100+ MW, the plant is not small — two VVER-1000s alone equal the output of two large coal-fired stations. The SMRs add only 110 MW; the bulk of the capacity is in the large reactors.
Room for disagreement
  • Uzbek officials have pushed back on 'delay' framing — Uzatom says the March 2026 first concrete for the SMR unit came ahead of the originally scheduled December 2026 milestone, so by their account the project is running early, not late.

When will it go live?

The plant comes online in stages: the first small reactor is due in 2029, the first large reactor in 2033, and full capacity by 2035.

Why it matters: A nine-year build window is fast by nuclear standards, but it means Uzbekistan's electricity shortage won't get much relief from this project until the mid-2030s.

  • The two RITM-200N small modular reactors are targeted for 2029, with units staggered roughly six months apart.
  • The first VVER-1000 large reactor is scheduled for 2033; the second completes the plant by 2035.
  • Rosatom's projected contract value is $24.7 billion — giving Moscow strong incentive to hit those dates.

Room for disagreement
  • Uzatom has had to publicly clarify the timeline after reports of delays, suggesting the 2029 SMR target is optimistic — construction of this reactor type at scale is untested, and slippage is common in first-of-kind nuclear projects.

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.
