Rwanda aims to launch its first small modular reactor (SMR) by the early 2030s to diversify its energy mix and meet rising electricity demand. According to the Rwanda Atomic Energy Board (RAEB), the government is currently evaluating financing models with the United Nations Economic Commission for Africa (UNECA) to overcome the high upfront capital costs associated with nuclear infrastructure.
The Shift to Small Modular Reactors (SMRs)
Rwanda has opted for SMRs over traditional large-scale nuclear plants due to their flexibility and lower entry barriers. The International Atomic Energy Agency (IAEA) defines SMRs as units generating up to 300 megawatts of electricity—roughly one-third the capacity of conventional reactors. Because these units are factory-built and assembled on-site, they offer shorter construction timelines and require less initial investment than traditional plants.
The IAEA notes that SMRs are particularly suited for countries with smaller electricity grids or remote areas where transmission infrastructure is limited. In May, the IAEA confirmed that Rwanda has advanced to Phase 2 of its nuclear power programme, which focuses on the transition toward contracting and construction.
Solving the Nuclear Financing Gap
Despite their smaller size, SMRs demand significant capital. The International Energy Agency (IEA) identifies high capital costs and lengthy construction periods as the primary hurdles for nuclear projects globally. To mitigate these risks, the IEA states that governments typically provide direct investment, sovereign loans, or guarantees to attract private investors.
Lassina Zerbo, Chairperson of the RAEB, indicates that development finance institutions are becoming more open to nuclear projects. Zerbo noted that the World Bank has shifted its stance on financing nuclear energy, leading other development banks, including the African Development Bank (AfDB), to reconsider their positions.
To secure funding, Zerbo suggests a “blended financing mechanism” that could include:
- Public-Private Partnerships (PPPs): Sharing risk and investment between the state and private firms.
- Export Credits: Utilizing loans from countries exporting the technology.
- Mineral Tokenization: Using certified critical mineral reserves as financial instruments to fund infrastructure.
Strategic Partnerships with Rosatom and Holtec
Rwanda has signed cooperation agreements with two major global players to facilitate its nuclear ambitions. The state nuclear corporation of Russia, Rosatom, and the US-based Holtec International are both involved in the process. Holtec’s role specifically includes supporting site studies, planning for safe deployment, and mobilizing financing.
While these partnerships provide technical and planning expertise, neither company has publicly disclosed the final financial structure for the reactor’s construction. The RAEB emphasizes that funding is needed not just for the plant itself, but for “human capacity, pre-feasibility studies, design, and implementation” to ensure the value chain meets international standards.
Comparing African Nuclear Models
Rwanda’s approach contrasts with other nuclear initiatives on the continent, as shown in the table below:
| Country | Project/Plant | Financing Model | Current Status |
|---|---|---|---|
| Egypt | El Dabaa | Russian state loan (85% of costs) | Under Development |
| South Africa | Koeberg | State ownership (Eskom) | Operational |
| Rwanda | SMR Project | Evaluating blended/private models | Phase 2 (Preparatory) |
| Ghana | Nuclear Programme | Institutional/Regulatory strengthening | Preparatory Phase |
Next Steps for Implementation
Before construction can begin, the RAEB must complete several critical milestones. These include finalizing site selection, conducting environmental impact assessments, and strengthening the national regulatory framework. The government continues to study various funding models through UNECA to determine whether the first reactor will be funded via public borrowing, export credits, or a public-private partnership.
