Uzbekistan Project Signals New Era for Small Modular Reactor Technology
Russia’s state-owned nuclear energy giant, Rosatom, has officially begun construction of the world’s first export-oriented Small Modular Nuclear Power Plant (SMR) in Uzbekistan, a development that could offer valuable lessons for South Africa as it considers the future role of nuclear energy in its electricity mix.
The groundbreaking project marks a significant milestone for the global nuclear industry and highlights growing international interest in small modular reactors as countries seek reliable, low-carbon energy sources to support economic growth and energy security.
A ceremony held in Uzbekistan’s Jizzakh Region marked the start of construction on the first power unit of the integrated nuclear power plant. The project advanced to official construction status following the pouring of the first concrete into the facility’s foundation, in line with standards set by the International Atomic Energy Agency (IAEA).
Small Modular Reactors Gain Momentum Worldwide
The Uzbekistan project is widely regarded as a major test case for the commercial deployment of export-focused small modular reactor technology.
Unlike conventional nuclear power stations, SMRs are designed to be smaller, more flexible and potentially less expensive to construct. Supporters argue that these reactors can provide stable baseload power while complementing renewable energy sources such as solar and wind.
For South Africa, the project arrives at a time when discussions around energy diversification, grid stability and future electricity generation remain high on the national agenda.
South Africa’s Legacy in Small Modular Nuclear Technology
South Africa was once considered a global pioneer in the development of small modular nuclear reactors through its Pebble Bed Modular Reactor (PBMR) programme. The project attracted international attention during the early 2000s for its innovative reactor design and potential to position South Africa as a leader in next-generation nuclear technology.
However, the programme was ultimately discontinued during former President Jacob Zuma’s administration amid concerns over funding requirements and changing government priorities.
Despite the project’s cancellation, interest in South African-developed reactor technology has not disappeared.
Centurion-based Stratek Holdings is currently advancing plans to commercialise an updated version of the pebble bed reactor concept, incorporating technological improvements developed since the original programme was halted.
The renewed global focus on SMRs may create opportunities for South African companies and researchers to re-enter a market that is expected to expand significantly over the coming decades.
Nuclear Fuel Opportunities Could Benefit South African Companies
The growing international demand for small modular reactors is also creating opportunities beyond reactor construction.
Nasdaq- and JSE-listed ASP Isotopes has announced plans to supply High-Assay Low-Enriched Uranium (HALEU) fuel to global markets. HALEU is regarded as a critical fuel source for many advanced reactor designs, including several pebble bed modular reactor concepts currently under development around the world.
As more countries invest in advanced nuclear technologies, demand for specialised nuclear fuel is expected to increase substantially, potentially creating new opportunities for South Africa’s nuclear technology sector.
Uzbekistan Nuclear Plant Expected to Support Economic Growth
Rosatom officials say the new nuclear power station will play a major role in supporting Uzbekistan’s future electricity needs and economic development.
According to Andrey Petrov, First Deputy Director-General for Nuclear Energy at Rosatom, the plant is expected to provide up to 14% of Uzbekistan’s electricity demand once fully operational.
Petrov said the project would not only strengthen the country’s energy security but also drive industrial development, technological innovation and economic growth.
Rosatom has also proposed the development of an “atomic city” linked to the project, creating a specialised hub focused on nuclear science, technology and advanced engineering.
Nuclear Expansion Continues Across Africa
While South Africa remains the only African country currently operating a commercial nuclear power station, interest in nuclear energy is growing across the continent.
The Koeberg Nuclear Power Station in the Western Cape remains Africa’s sole operational nuclear facility and continues to play an important role in South Africa’s electricity generation mix.
Meanwhile, Egypt is constructing the El-Dabaa Nuclear Power Plant, one of the largest infrastructure projects currently underway on the continent. The project is expected to cost approximately $28.75 billion and is being developed with significant financial and technical support from Russia.
More than 30,000 people are currently employed on the project, highlighting the potential economic impact of large-scale nuclear developments.
South Africa and Russia Strengthen Nuclear Cooperation
South Africa and Russia have maintained longstanding cooperation in the nuclear sector, particularly in areas such as skills development, research and technology exchange.
In 2024, Rosatom and Eskom signed a cooperation agreement covering personnel training and educational initiatives through 2026. The partnership aims to strengthen technical expertise and support future nuclear development opportunities.
Earlier this year, Rosatom also signed a memorandum of understanding with the Nuclear Energy Corporation of South Africa (Necsa), focusing on knowledge sharing, workforce development and collaboration in nuclear and related technologies.
These agreements could help South Africa build the skills and technical capacity required should the country decide to expand its nuclear energy programme in the future.
What the Rosatom SMR Project Means for South Africa
The launch of the world’s first export small modular nuclear power plant represents more than a technological milestone. It provides a real-world opportunity for South Africa to observe how advanced reactor technologies are deployed, regulated and operated at a commercial scale.
As electricity demand continues to rise and governments search for reliable low-carbon energy solutions, small modular reactors are increasingly being viewed as a potential component of future energy systems.
For South Africa, which already possesses decades of nuclear expertise and a history of innovation in reactor technology, the success of projects such as Uzbekistan’s SMR development could help shape future decisions around energy security, industrial development and long-term electricity generation.
