26 July 2024: While nuclear energy presents significant challenges and risks, renewable energy sources offer a more viable, safe, and economically beneficial path for South Africa’s energy future, aligning with the principles of a just transition.
- Costs and Development Time: Nuclear energy projects require substantial initial financial investment and, with the long construction timelines (often extending beyond a decade), can be a massive burden to the economy. This makes nuclear much less viable when compared to renewable energy projects that are significantly cheaper and can be deployed in a matter of months.
- Safety: The potential for catastrophic nuclear accidents, as seen in Chernobyl and Fukushima, poses significant safety concerns, especially since South Africa’s current infrastructure and emergency response systems may not be able to adequately manage these risks. Renewables, on the other hand, pose minimal safety risks – no catastrophic failures or meltdowns, and no hazardous waste.
- Waste: Nuclear reactors produce long-lived radioactive waste, which requires secure, long-term storage solutions. Currently, there are no long-term storage or disposal solutions available for high level radioactive waste. On the other hand, renewables produce little to no greenhouse gas emissions and instead, offer a sustainable and environmentally friendly energy solution.
- Dependence on Imported Technology and Fuel: Nuclear energy is heavily dependent on imported technology and expertise, and enriched uranium, and is susceptible to international market fluctuations. With renewables, South Africa can harness abundant sun and wind (supported by battery storage), to promote energy independence and long-term sustainability.
- Job Creation: The renewable energy sector can stimulate local economies and promote inclusive growth, by creating numerous jobs across various skill levels, from manufacturing and installation to maintenance and operations, while the nuclear sector mostly needs highly specialized skills, which does not support broad-based economic development or job creation.
