Nuclear power remains a cornerstone of energy policy in many developed nations, powering cities with clean, reliable, and large-scale electricity. As Kenya contemplates its own nuclear ambitions, understanding how advanced economies have leveraged nuclear power—and overcome its challenges—offers valuable insight into the potential path forward.
The Global Landscape of Nuclear Power
As of June 2025, 31 countries operate nuclear power plants, generating about 10% of the world’s electricity1. The United States is the largest producer by volume, while France leads in the proportion of national electricity from nuclear—about 65% of its total supply12. Other significant users include China, Russia, Canada, and South Korea.
| Country | Reactors (In Use) | % of National Electricity from Nuclear | Capacity Factor (%) |
|---|---|---|---|
| United States | 94 | 18.2 | 92.5 |
| France | 57 | 67.3 | 74.2 |
| China | 57 | 4.7 | 90.8 |
| South Korea | 26 | 31.7 | 79.6 |
| Canada | 19 | 13.4 | 68.2 |

Benefits of Nuclear Power for Developed Countries
1. Clean, Low-Carbon Energy
- Nuclear power produces electricity without greenhouse gas emissions, making it a key tool for climate change mitigation32.
- France, for example, rapidly reduced its carbon footprint in the 1970s and 80s by expanding nuclear, slashing emissions while ensuring energy security2.
2. Reliability and Scale
- Nuclear plants operate at high capacity factors (often above 85%), meaning they provide steady, 24/7 baseload power—unlike intermittent renewables13.
- This reliability supports industrial growth and urbanization.
3. Energy Security
- By reducing dependence on imported fossil fuels, nuclear power enhances national energy security—a major driver for France and South Korea2.
4. Economic Advantages
- Nuclear plants create thousands of skilled jobs and stimulate local economies, especially during construction and operation phases3.
- Advanced economies have developed robust supply chains and expertise, lowering long-term operational costs.
Overcoming Challenges: How Developed Countries Succeeded
A. Safety and Regulation
- Stringent safety standards, enforced by independent regulators, have made nuclear power among the safest forms of large-scale energy generation3.
- Continuous technological innovation—such as advanced emergency cooling systems and passive safety features—has reduced accident risk3.
B. Waste Management
- Developed countries have established long-term waste storage and disposal strategies, including deep geological repositories and robust interim storage solutions.
- Ongoing research focuses on recycling spent fuel and minimizing waste volumes.
C. Public Acceptance and Transparency
- Transparent communication about risks and benefits, coupled with strict oversight, has helped build public trust—especially in countries like France and Sweden.
D. Cost and Project Management
- While nuclear plants are capital-intensive, mature economies have streamlined construction through standardized designs and experienced contractors.
- Some countries (e.g., South Korea) have reduced costs by developing domestic reactor technologies and exporting expertise.
E. Environmental and Water Use
- Advanced reactor designs now require less water for cooling, addressing concerns in water-scarce regions3.
- Environmental monitoring and site selection processes minimize ecosystem impacts.
Global Challenges and the Evolving Nuclear Sector
Despite successes, the global nuclear industry faces:
- Rising construction costs and delays—notably in Western markets4.
- Competition from renewables, which have seen dramatic cost reductions.
- Cybersecurity threats, requiring constant vigilance and investment4.
- Political and regulatory shifts, as seen in Germany’s phase-out and Japan’s post-Fukushima reassessment14.
Yet, international cooperation and innovation—such as the development of Small Modular Reactors (SMRs)—aim to address these hurdles and make nuclear more accessible and flexible4.
Kenya’s Nuclear Ambitions: Context, Opportunities, and Challenges
Kenya is planning to construct its first nuclear power plant by 2027, with electricity generation expected by 20345. The government sees nuclear as essential to meet projected power demand, which could rise twentyfold by 2050 due to rapid industrialization5.
Potential Benefits for Kenya
- Clean, large-scale electricity to support industrial growth and urbanization.
- Reduced reliance on imported fuels, enhancing energy security.
- Stable baseload power to complement variable renewable sources.
Key Challenges
| Challenge | Developed Countries’ Solution | Kenya’s Current Status |
|---|---|---|
| High Capital Cost | Standardized designs, local supply chains | Kenya faces high upfront costs6 |
| Radioactive Waste | Deep geological storage, recycling | Kenya lacks waste infrastructure6 |
| Water Usage | Advanced cooling, site selection | Coastal sites considered, but water scarcity is a concern56 |
| Regulatory Framework | Strong independent agencies | Kenya is developing its framework5 |
| Public Acceptance | Transparency, education | Local opposition and environmental concerns exist56 |
Environmental and Social Considerations
- Greenpeace Africa and other groups warn of risks to coastal ecosystems and question the need for nuclear given Kenya’s abundant renewable resources5.
- The management of radioactive waste and the need for robust safety oversight are critical, especially in a country with limited prior experience6.
Lessons for Kenya
Kenya can draw from the experiences of developed countries by:
- Investing in regulatory capacity and safety culture from the outset.
- Engaging the public transparently to build trust and address concerns.
- Considering hybrid energy strategies, where nuclear complements renewables for a balanced, resilient grid.
- Pursuing international partnerships for technology transfer, training, and financing.
Conclusion
Nuclear power has powered the cities and industries of developed nations for decades, delivering clean, reliable energy while overcoming significant challenges through innovation, regulation, and public engagement. For Kenya, the path to nuclear power is complex but not insurmountable. With careful planning, strong governance, and lessons learned from global leaders, nuclear energy could play a transformative role in Kenya’s energy future—if its challenges are met with the same resolve and expertise.
