Rosatom Takes Nuclear Push to Africa as Tanzania’s Mkuju Uranium Project Advances

Russia’s state nuclear corporation Rosatom will use the Third Russia–Africa Summit in Moscow on October 28 and 29 to promote nuclear power, uranium mining, nuclear medicine, agricultural applications and specialist training to African governments, with the company saying new bilateral documents and implementation roadmaps are expected to be signed on the sidelines of the meeting. For Tanzania, however, Rosatom arrives at the summit with considerably more than a prospective cooperation agreement. Its subsidiaries are already developing the Mkuju River uranium project in Ruvuma, Tanzanian students are being trained in Russian mining and nuclear related programmes, and President Samia Suluhu Hassan confirmed in June that the government is discussing small nuclear power plants with the Russian corporation as Tanzania considers how to meet electricity demand projected to rise sharply over the next quarter century. The summit will be held at Moscow’s Gostiny Dvor as part of the wider Russia–Africa Economic and Humanitarian Forum, three years after the second summit in St Petersburg. The official programme places nuclear energy alongside infrastructure, logistics, trade, payments, digitalisation and food security, while Rosatom says its participation as a Title Partner will include discussions on both conventional nuclear projects and smaller technologies intended for industrial, mining and remote electricity consumers. For Tanzania, the most substantial part of that relationship is currently not a power reactor but uranium. Mantra Tanzania Limited, part of Rosatom controlled Uranium One Group, holds the Mkuju River project in Namtumbo District, where the Nyota sandstone deposit has been studied for nearly two decades and received a Special Mining Licence in 2013. A pilot uranium processing plant was commissioned in July 2025 to test the planned extraction and processing system before development of the full commercial facility. Tanzania’s Ministry of Minerals said again in May 2026 that it wants Mantra to move into production on schedule, while the company has maintained an annual production target of approximately 3,000 tonnes of uranium once the main operation is fully commissioned. Nyota’s 58,500 Tonnes Are Supported by International Resource Data Rosatom’s summit statement places the Nyota deposit’s uranium resource at about 58,500 tonnes. That number closely matches the most detailed international assessment available rather than standing only as a company estimate. The OECD Nuclear Energy Agency and International Atomic Energy Agency’s Uranium 2024: Resources, Production and Demand recorded 58,489 tonnes of in situ uranium at Nyota, comprising 47,927 tonnes of measured and indicated resources and another 10,562 tonnes in the inferred category. The report describes Nyota as accounting for more than 80 percent of Tanzania’s identified conventional uranium resources at the time of the assessment. The distinction between the Nyota figure and Tanzania’s national uranium resource is important because they are not the same measurement. Nyota is one deposit within a broader national geological inventory that includes occurrences around Manyoni, Bahi, Mtonya and other areas. More recent international resource tables now place Tanzania’s identified recoverable uranium resources at around 75,000 tonnes under the stated cost category, meaning the country’s total uranium potential extends beyond the 58,500 tonnes associated with Mkuju River. The planned 3,000 tonne annual production rate is also large enough to have a measurable effect on Africa’s uranium supply if Mantra actually reaches that level. Namibia, Africa’s largest current producer, mined 7,333 tonnes of uranium in 2024, while Niger produced 962 tonnes and South Africa about 200 tonnes. On those production levels, a fully operating Mkuju River mine producing 3,000 tonnes a year would have ranked second among African producing countries in 2024, behind Namibia but ahead of Niger and South Africa. It would also be comparable in scale with some of the larger individual uranium operations internationally rather than a marginal new mine. That comparison is more useful than describing Tanzania simply as a future “major producer,” because the project has not yet reached commercial output and the African production ranking could change before Mkuju is commissioned. Namibia is expanding production, uranium projects elsewhere are being developed, and Niger’s output has been affected by political and operational disruption. Mkuju’s significance therefore rests on a production target that is substantial by current African standards, but which still has to be delivered through construction, commissioning and sustained commercial mining. Mkuju River Has Moved Beyond Exploration but Is Not Yet a Producing Mine The project’s history also requires some qualification because Mkuju River has spent years in development rather than production. Uranium One acquired control of Mantra after Russian state backed Atomredmetzoloto purchased the company in 2011, but weak uranium prices following the Fukushima accident and the economics of developing the deposit delayed commercial construction. The present development cycle became much more visible when President Samia inaugurated the pilot processing plant in July 2025, giving Mantra a facility intended to test ore treatment and generate engineering data for the larger plant. World Nuclear News reported at the time that construction of the main facility was scheduled to begin in the first quarter of 2026, with commissioning targeted for 2029. Tanzania’s Ministry of Minerals subsequently pressed the company in May 2026 to keep the project on schedule and said commercial production of around 3,000 tonnes a year would create more than 4,000 jobs and bring additional economic activity to communities surrounding Namtumbo. The ministry has also described the project as one of Tanzania’s major strategic mining developments. Those employment and production numbers remain projections until the commercial mine is built and operating, but the government’s intervention demonstrates that Mkuju River is now being treated as an implementation project rather than merely a geological prospect. The development nevertheless faces the same commercial tests as any large mine. The deposit has to be converted from a geological resource into recoverable production at a cost that remains competitive over the life of the operation, the processing system tested at pilot scale has to work commercially, financing must be secured and the mine must comply with environmental and radiation protection requirements that are more demanding than those applying to many conventional minerals. Uranium prices have improved substantially from the depressed levels that delayed projects after 2011, while international interest in nuclear power has strengthened demand expectations, but neither factor eliminates execution risk. Tanzania’s economic interest in the project also extends beyond the volume of uranium exported. Government statements have referred to jobs, community investment, local procurement and the strategic value of adding another mineral to a mining economy still dominated by gold. The more important long term measure will be how much Tanzanian labour, technical expertise and supplier activity is embedded in the project as production scales, particularly because uranium mining requires specialised geological, radiation safety and processing expertise that remains relatively scarce domestically. Russia Is Training Tanzanians for the Industry It Is Helping to Build Rosatom’s emphasis on education in its summit programme is closely connected to that skills requirement. The corporation says 14 Tanzanian students were studying nuclear and related subjects at Russian universities through its supported programmes as of August 2026, including six students enrolled in a geology and mining programme involving RUDN University, MISIS University and the University of Dar es Salaam. The company also points to the six Tanzanian students who graduated in 2025 from the joint Mining Geology master’s programme. The graduation is independently documented. RUDN and Rosatom reported in July 2025 that six Tanzanians completed the programme, including practical exposure to uranium mining through an internship at Dalur, one of Rosatom’s uranium operations in Russia. Students were trained in areas including in situ recovery technology, occupational safety and uranium geology. Five Tanzanian students were again reported undertaking industrial training at Dalur later in 2025. This training arrangement is commercially relevant to Rosatom because international nuclear projects require a pipeline of local engineers, geologists, operators and regulators long before a reactor or mine reaches operation. It is equally important for Tanzania because technical capacity determines how much of the value surrounding Mkuju River can remain in the country. A uranium industry staffed primarily through imported expertise would create a very different economic outcome from one in which Tanzanian geologists, engineers, radiation specialists and managers progressively occupy senior technical roles. The same issue would become considerably more important if Tanzania proceeds from uranium mining into nuclear electricity generation. A country can develop a uranium mine without operating a power reactor, and uranium mined in Tanzania would enter an international fuel supply chain rather than automatically being consumed domestically. Building a nuclear power programme would require a separate set of institutions covering reactor regulation, nuclear safety, emergency preparedness, fuel management, waste, grid planning, financing and independent oversight. Tanzania’s Nuclear Power Discussions Are Real, but No Reactor Has Been Ordered Rosatom’s summit release connects mining and training with a much wider offer to African countries, including conventional nuclear energy, small reactors, floating power units, nuclear medicine and agricultural technologies. Tanzania has already moved far enough in its energy discussions for nuclear power to be part of government planning, but there is currently no evidence of a final reactor procurement, construction contract or financing agreement with Rosatom. President Samia said during the St Petersburg International Economic Forum in June 2026 that Tanzania was interested in small nuclear power plants and that Rosatom was discussing the matter with the country. The statement was made as Tanzania examined how to diversify an electricity system that has expanded rapidly following completion of the 2,115MW Julius Nyerere Hydropower Project. Installed generation capacity has reached about 4,646MW against peak demand of roughly 2,271MW, while government projections cited in October place electricity demand at around 70,000MW by 2050. Those numbers explain why the nuclear discussion is about Tanzania’s future industrial structure rather than an immediate electricity deficit. The country currently has more installed capacity than peak demand, but a 2050 economy requiring tens of thousands of megawatts would need continuous investment in hydropower, natural gas, solar, wind, transmission, storage and potentially nuclear generation. Whether nuclear becomes competitive within that mix will depend on financing costs, construction time, grid requirements and the performance of competing technologies rather than simply the availability of uranium within Tanzania. Domestic uranium resources do not by themselves make nuclear electricity cheap. Mining uranium represents only one part of the nuclear fuel cycle, while a power programme requires enrichment, fuel fabrication, reactor technology and long term technical services. Tanzania could therefore become an important uranium exporter without ever building a domestic nuclear reactor, just as countries with little uranium production can operate nuclear power plants using imported fuel. The strategic case for Tanzania would have to be demonstrated through the economics and reliability of the electricity generated rather than by treating Mkuju River as an automatic justification for nuclear power. Rosatom Is Bringing Floating Nuclear Plants Into Its African Offer One technology Rosatom intends to promote at the summit is its FPU 100 floating nuclear power unit, designed to provide about 100MW of electricity from two RITM 200M reactors. Rosatom has been marketing the technology to coastal African markets as a potential electricity source for industrial zones, ports, mines and remote areas where constructing a large conventional nuclear plant may be difficult. Earlier this year, the company specifically presented the system in South Africa as an option for industrial areas around Richards Bay. This is no longer only a conceptual product. Rosatom announced on October 16 that it had reached an agreement with an Indonesian company for two FPU 100 units with combined capacity of 200MW for North Maluku, which the company describes as the first export agreement for electricity supplied from this generation of floating unit. Rosatom is also manufacturing related RITM reactor systems for floating power projects supplying a copper mining cluster in Russia’s Chukotka region. That commercial progress makes Rosatom’s African offer more concrete than it was several years ago, but there is no publicly announced Tanzanian agreement for a floating power unit. The summit press release describes the technology as one of the solutions Rosatom will present to coastal African countries rather than identifying Tanzania as a customer. Any suggestion that Tanzania is preparing to purchase an FPU would therefore run ahead of the evidence currently available. Rosatom says the model could reduce some of the infrastructure requirements normally associated with nuclear plants because fresh and spent fuel would be handled at specialised facilities in Russia rather than at the customer’s operating location. That arrangement could lower the need for local fuel handling infrastructure, while also tying the operator to Russian fuel cycle and technical services over a long period. For an African government evaluating the technology, the commercial calculation would consequently extend beyond the initial power unit to electricity tariffs, financing, port infrastructure, long term service agreements, transmission, security, regulation and the terms governing spent fuel and decommissioning. Rosatom’s African Strategy Is Built Around Long Term Relationships Nuclear energy differs from many infrastructure exports because the commercial relationship can continue for decades after the initial agreement. Reactor suppliers can remain involved in financing, engineering, construction, fuel supply, training, maintenance and eventually decommissioning. Mining relationships can similarly extend across exploration, extraction, processing and long term supply contracts. Rosatom’s emphasis at the Russia–Africa Summit on education, national nuclear industries and what it describes as technological sovereignty should therefore be read alongside the commercial durability of the relationships it is seeking to establish. Africa already contains Rosatom’s most advanced reactor construction project outside Russia’s immediate neighbourhood through Egypt’s El Dabaa nuclear power station, while the corporation has signed nuclear cooperation agreements or pursued projects with governments elsewhere on the continent. The Moscow summit gives it an opportunity to expand those relationships as countries face rising electricity demand and increasing pressure to find dependable low carbon generation alongside renewable energy. Tanzania occupies an unusual position within that strategy because Rosatom already controls the company developing the country’s largest uranium deposit while Russian institutions are training Tanzanian specialists and the two governments are discussing future nuclear power options. The individual strands remain legally and commercially separate, but together they create a relationship stretching from mineral extraction to skills development and potentially electricity generation. The Mkuju Project Is the Immediate Economic Test For Tanzania, the most consequential near term issue arising from Rosatom’s summit announcement is therefore not whether the country will buy a Russian reactor. It is whether Mkuju River can move from pilot processing into commercial uranium production on the schedule now being discussed. The geological basis is substantial. The OECD and IAEA data support approximately 58,500 tonnes of uranium at Nyota, while newer international assessments place Tanzania’s broader identified uranium resource still higher. The proposed production rate of 3,000 tonnes a year would, based on recent output data, immediately make Tanzania one of Africa’s largest uranium producing countries. What remains to be demonstrated is whether the commercial plant can be financed, constructed and operated at that scale and whether the projected economic gains extend beyond uranium exports into Tanzanian employment, technical capability, supplier development and fiscal revenue. Rosatom’s participation in the Russia–Africa Summit gives the company another platform to present nuclear technology as part of a wider industrial development proposition for African countries, but Tanzania already provides a practical case against which that proposition can eventually be measured. Mkuju River has identified resources, a licensed project, an operating pilot plant, a stated production target and a government pushing for implementation. Its progress over the next several years will provide more information about the depth of Russia and Tanzania’s nuclear cooperation than another memorandum signed in Moscow. The nuclear power question sits further ahead. Tanzania’s projected electricity requirements make discussion of nuclear generation reasonable within long term energy planning, particularly if industrialisation, mining and electrified transport raise demand towards the levels envisaged under Dira 2050. Any reactor decision, however, would require considerably more evidence on costs, financing, grid needs, regulatory capability and competing generation technologies than is currently available publicly. What Tanzania already has is a uranium project capable, on paper, of materially changing its mineral export profile. What it does not yet have is a commercial uranium mine or an approved nuclear power project. The distinction is central to understanding both the significance and the limits of Rosatom’s expanding role in the country. FAQ How much uranium is at Tanzania’s Mkuju River project? The OECD Nuclear Energy Agency and IAEA recorded approximately 58,489 tonnes of in situ uranium at the Nyota deposit within Mkuju River, including 47,927 tonnes in measured and indicated resources and 10,562 tonnes in inferred resources. How much uranium could Mkuju River produce each year? Mantra Tanzania and Tanzanian government statements place planned commercial production at approximately 3,000 tonnes of uranium annually. How significant would 3,000 tonnes be in Africa? Using 2024 production as a comparison, 3,000 tonnes would have placed Tanzania second among African uranium producing countries, behind Namibia’s 7,333 tonnes and ahead of Niger’s 962 tonnes and South Africa’s approximately 200 tonnes. Actual rankings when Mkuju enters production may differ. When is Mkuju River expected to begin commercial production? When the pilot processing plant was commissioned in July 2025, the main facility was scheduled for commissioning in 2029. The project is still under development, so that remains a target rather than a completed production date. Does Rosatom own the Mkuju River uranium project? The project is operated by Mantra Tanzania Limited, a subsidiary of Uranium One Group, which is part of Russia’s Rosatom group. Is Tanzania building a Russian nuclear power plant? No final nuclear power plant contract has been announced. President Samia Suluhu Hassan said in June 2026 that Tanzania is interested in small nuclear plants and that discussions with Rosatom are underway, but no final reactor technology, site, financing package or construction schedule has been announced. What nuclear technology is Rosatom offering African countries? Rosatom is promoting large nuclear projects as well as smaller solutions including 100MW floating power units using two RITM 200M reactors, alongside nuclear medicine, mining, training and other peaceful nuclear technologies. When is the Third Russia–Africa Summit? The summit and accompanying Russia–Africa Economic and Humanitarian Forum will take place in Moscow on October 28 and 29, 2026.
