Tanzania Is in Discussions With Russia's Rosatom to Build a Small Nuclear Power Plant. President Samia Announced It at SPIEF 2026. Tanzania Already Has the Uranium.

DAR ES SALAAM — Tanzania is in active discussions with Rosatom, Russia's state nuclear energy corporation, about constructing a small nuclear power plant, President Samia Suluhu Hassan confirmed at the 29th St. Petersburg International Economic Forum on June 5, 2026. "We are transitioning to clean energy," President Samia said. "We are interested in the sort of energy mix that will enable us to generate clean energy and interested in building small nuclear power plants, which Rosatom is currently discussing with Tanzania." The statement is not a memorandum of understanding or a signed agreement. It is a presidential confirmation that the discussions are live and that the political will at the highest level of Tanzania's government is present. In the language of large-scale energy infrastructure development, that confirmation is a material development whose implications extend from Tanzania's long-term energy security to its emerging position as Africa's most actively diversifying energy economy. Tanzania already has the uranium What makes the Rosatom announcement significantly more than a standard bilateral nuclear cooperation statement is the specific combination of assets Tanzania brings to the discussion. In 2025, Rosatom launched a pilot facility at the Mkuju River uranium project in Tanzania's southern region. Rosatom CEO Alexei Likhachev has confirmed that the deposit has explored uranium reserves of more than 44,000 tonnes, describing it as one of the most promising uranium projects in the world. Tanzania is not proposing to import both the technology and the fuel for nuclear power generation. It is proposing, at least in structural terms, to use its own domestically sourced uranium to power its own reactors. That combination is available to very few developing economies on the African continent. Most countries that have expressed interest in nuclear energy face the full import dependency challenge: technology from an external partner, fuel from an external supplier, operational expertise from external contractors, and financing from external capital markets. Tanzania's uranium endowment at Mkuju River removes the fuel dependency from that equation, potentially changing the economics, the energy security argument, and the strategic rationale for nuclear power in ways that make the calculation different from the standard developing economy nuclear discussion. The 44,000-plus tonnes of explored reserves also raises a second dimension of the Mkuju River story that sits alongside the domestic power generation discussion. Tanzania with a developed uranium extraction and processing industry is Tanzania as a potential African uranium exporter, supplying the fuel cycle for nuclear power plants across the continent and internationally at a moment when uranium demand is growing as the global nuclear renaissance accelerates. The pilot facility Rosatom launched in 2025 is the first operational step toward that broader resource development. Rosatom's global position and what it means for Tanzania The choice of Rosatom as the discussion partner is not incidental. Rosatom is currently involved in over 80 percent of new nuclear power plant builds worldwide, a market share that makes it the dominant global partner for countries seeking nuclear energy access, particularly developing economies without existing nuclear industries. Rosatom's engagement model with developing country partners typically encompasses the full nuclear value chain: reactor design and construction, fuel supply, operational training and staffing support, long-term maintenance agreements, and regulatory framework development. For a country entering nuclear power without an existing nuclear industry, that comprehensive engagement model reduces the barriers to entry that would otherwise make the technology inaccessible. Egypt's El Dabaa nuclear power plant, being built by Rosatom on the Mediterranean coast, is the closest regional reference case for how the engagement model works in an African context. The small modular reactor technology that the discussions with Tanzania are centred on represents a different risk and cost profile from the large-scale nuclear plants that have historically defined civilian nuclear power. Small modular reactors, typically generating between 50 and 300 megawatts per unit, are designed for deployment in markets where the grid size, financing capacity, or site constraints make large-scale nuclear uneconomic or impractical. For Tanzania, whose current installed generation capacity stands at approximately 3,500 megawatts across all sources and whose energy demand is growing rapidly from the manufacturing investment acceleration that TISEZA has been facilitating, a small modular reactor whose output can be sized to the grid's absorption capacity is a more practically deployable technology than a conventional gigawatt-scale nuclear plant. The energy mix logic behind the announcement Tanzania's energy strategy has never been single-source. The Julius Nyerere Hydropower Project at 2,115 megawatts provides the hydro backbone. Natural gas reserves offshore and at Mnazi Bay provide the thermal generation complement. Solar investment is expanding across the country, with TISEZA's SEZ framework providing 2,000 megawatts of gas-powered electricity to manufacturing investors. The Rwf 7.8 trillion Rwanda budget and Ethiopia's Koysha dam investment demonstrate the regional trend toward energy portfolio diversification that Tanzania's nuclear discussion fits within. President Samia's framing of the nuclear discussion within the clean energy transition is precise. Hydropower is clean but weather-dependent: drought conditions reduce generation from hydro-dominant systems and Tanzania experienced exactly this constraint in recent years when below-average rainfall reduced the contribution of existing hydro capacity and exposed the industrial and commercial economy to power availability risk. Solar is clean but intermittent. Natural gas is dispatchable but produces emissions. Nuclear is clean, dispatchable, and baseload, meaning it generates reliably regardless of weather conditions and can provide the stable baseload power that industrial manufacturing processes require continuously rather than intermittently. For the industrial transformation that Tanzania's Vision 2050, the Bagamoyo SEZ, and the TISEZA manufacturing acceleration are collectively building toward, the energy mix question is not merely about availability. It is about the reliability and affordability of power at the industrial scale that manufacturing competitiveness requires. A textile manufacturer, a mineral processing facility, or a pharmaceutical plant cannot operate competitively on power supplies that interrupt when rainfall is low or when solar generation drops at night. Nuclear baseload addresses exactly the reliability gap that Tanzania's current energy mix contains. Tanzania in the African nuclear picture Tanzania's nuclear discussion places it within a small but growing group of African countries that have moved beyond expressing general interest in nuclear energy toward active planning and partnership engagement. South Africa operates the Koeberg Nuclear Power Station near Cape Town, the only operating commercial nuclear power plant in sub-Saharan Africa, and is planning new nuclear capacity as part of its IRP2023 energy development framework. Egypt's El Dabaa plant, under Rosatom construction, will be the continent's second civilian nuclear power station when operational. Kenya has expressed interest in nuclear energy through the Nuclear Power and Energy Agency. Ghana has been engaged with the International Atomic Energy Agency on nuclear planning. Nigeria has conducted preliminary studies. Tanzania's combination of expressed presidential commitment, active Rosatom engagement, domestic uranium reserves, and the energy demand trajectory of an economy whose manufacturing investment acceleration is creating industrial baseload power requirements positions it as one of the more credible African nuclear candidates relative to the gap between aspiration and actionable planning that characterises many of the other cases. The geopolitical dimension of the Rosatom engagement is visible in the broader context of Tanzania's Moscow state visit and President Samia's SPIEF participation. Tanzania's non-aligned foreign policy, which Uchumi360 has documented as enabling the multipolar energy and infrastructure partnerships whose combination is accelerating the country's infrastructure decade, means the nuclear discussion with Rosatom does not preclude parallel engagement with Western or other technology providers. But given Rosatom's existing presence at Mkuju River through the pilot facility, its 80 percent market share in new nuclear builds, and the Russia-Tanzania relationship whose deepening the June 2026 Moscow state visit formalised through multiple cooperation agreements, the Rosatom pathway is the most operationally advanced option currently on Tanzania's nuclear table. What comes next A presidential announcement at SPIEF confirming discussions is the political signal. The technical, financial, regulatory, and legal work that converts a nuclear power discussion into a nuclear power plant is a different and much longer process. A small modular reactor from concept confirmation to grid connection typically requires eight to fifteen years of planning, regulatory development, site selection, financing arrangement, construction, and commissioning. Tanzania would need to develop a nuclear regulatory framework whose absence is a prerequisite for any licensed reactor construction. Financing structures for small modular reactor projects in developing economies are still being developed globally as the SMR technology itself is in the early commercial deployment phase. Training the Tanzanian nuclear workforce whose expertise would be required to operate the facility is a multi-year programme. None of these challenges are unique to Tanzania or insurmountable for a country with the institutional capacity and political consistency that its track record on large infrastructure project delivery demonstrates. The GERD, the Tanzania SGR, and the Julius Nyerere Hydropower Project are all precedents for complex, multi-year energy and infrastructure project delivery in the region. But they are worth naming honestly so that the gap between President Samia's SPIEF confirmation and the eventual first megawatt of Tanzanian nuclear power is understood as a decade-long programme rather than a near-term event. What the announcement does immediately is confirm Tanzania's ambition and its direction. A country that has 44,000 tonnes of uranium in the ground and is actively discussing with the world's leading nuclear technology company how to use it to generate clean power for its industrialising economy is a country whose energy strategy is more sophisticated, more forward-looking, and more seriously engaged with the full range of available options than its current energy mix discussion has typically reflected. Tanzania already has the uranium. The discussion with Rosatom is about what to do with it. FAQ What did President Samia announce about nuclear power at SPIEF 2026? President Samia Suluhu Hassan confirmed at the St. Petersburg International Economic Forum on June 5 2026 that Tanzania is in active discussions with Rosatom, Russia's state nuclear energy corporation, about constructing a small nuclear power plant. She framed the discussions within Tanzania's clean energy transition and energy mix diversification strategy, stating Tanzania's interest in building small nuclear power plants that Rosatom is currently discussing with the country. Does Tanzania have its own uranium for nuclear power? Yes. Tanzania has over 44,000 tonnes of explored uranium reserves at the Mkuju River project in the country's southern region, described by Rosatom CEO Alexei Likhachev as one of the most promising uranium deposits in the world. Rosatom launched a pilot facility at the project in 2025. Tanzania's domestic uranium endowment removes the fuel import dependency that makes nuclear energy more complex for most developing countries and potentially positions Tanzania as an African uranium exporter. Why is Rosatom Tanzania's nuclear discussion partner? Rosatom is involved in over 80 percent of new nuclear power plant builds worldwide, making it the dominant global partner for countries seeking nuclear energy access. Its engagement model for developing countries encompasses the full nuclear value chain including reactor construction, fuel supply, operational training, maintenance, and regulatory framework development. Rosatom's existing presence at Tanzania's Mkuju River uranium project through its 2025 pilot facility launch gives it an established operational relationship in Tanzania that precedes the nuclear power discussions. What is a small modular reactor and why is it relevant for Tanzania? A small modular reactor is a nuclear power unit typically generating between 50 and 300 megawatts, designed for deployment where grid size, financing capacity, or site constraints make conventional gigawatt-scale nuclear plants impractical. For Tanzania, whose grid is approximately 3,500 megawatts total and whose energy demand is growing from manufacturing investment acceleration, SMR technology can be sized to match current grid absorption capacity and scaled up incrementally as demand grows, making it more practically deployable than a large conventional nuclear plant. How long would it take Tanzania to build a nuclear power plant? A small modular reactor from concept confirmation to grid connection typically requires eight to fifteen years of planning, regulatory framework development, site selection, financing arrangement, construction, and commissioning. Tanzania would need to develop a nuclear regulatory framework, secure financing through structures appropriate for SMR projects in developing economies, train a Tanzanian nuclear workforce, and complete the technical and safety processes that international nuclear standards require before the first megawatt of nuclear power reaches the grid.
