South Africa Plans Major Expansion of Nuclear Energy Capacity Amidst Regional Developments

South Africa is poised to significantly enhance its nuclear energy capacity, with ambitious plans to add 10 gigawatts over the next 10 to 15 years. Deputy Director General Zizamele Mbambo, representing the Department of Mineral Resources and Energy, articulated the nation’s objective to achieve self-sufficiency across the entire nuclear value chain. This initiative is underpinned by South Africa’s extensive experience in nuclear technology, exemplified by the recent lifetime extension of the Koeberg 1 unit and an anticipated decision on the second unit's extension in November.

The proposed program includes environmental authorizations for a site near Koeberg that could support approximately 4.6 GW of new capacity, as the government explores both conventional and small modular reactors. As part of this vision, uranium has been declared a strategic mineral, facilitating the re-establishment of a comprehensive nuclear fuel cycle within the country. Mbambo noted the growing global consensus on the necessity of nuclear energy in achieving net-zero emissions, aligning South Africa's plans with broader clean energy goals.

Historically, South Africa has been at the forefront of developing pebble bed modular reactor technology, which had been dormant for over three decades. Now, the government aims to revive this program, positioning the country as a leader in small modular reactor development. Additionally, the Safari research reactor, pivotal for medical isotope production, is set for life extension, while plans for a new multipurpose reactor are underway to maintain the country's competitive edge in nuclear advancements.

Speaking at a recent symposium attended by over 1,000 delegates, Mbambo highlighted the openness to various financing solutions, including private investment and international collaboration. He also underscored the importance of training specialists from other African nations, fostering regional expertise in nuclear energy.

In a related discussion, Mohamed Saad Dwiddar, director of the El Dabaa nuclear power plant project in Egypt, reported significant progress with a workforce of 25,000 on-site. He anticipates the installation of the reactor pressure vessel for the first unit by the end of the year, with plans for the final unit to commence operation by 2030. Meanwhile, Rwanda is moving forward with pre-feasibility studies for its nuclear ambitions, navigating financing options and technology selection amid challenges of public acceptance and differentiation from nuclear weapons.

Loyiso Tyabashe, CEO of the South African Nuclear Energy Corporation, echoed the importance of advocacy to promote the socio-economic benefits of nuclear energy, particularly in job creation. Ensuring a skilled workforce is vital, with both Egypt and Rwanda investing in educational initiatives to prepare their engineers and technicians for upcoming projects. Conversely, South Africa faces a different challenge, as its established nuclear history has seen skilled professionals seek opportunities abroad due to a lack of new projects.

The discussion also touched on the systemic risk premium associated with financing in Africa. Tyabashe noted the importance of showcasing successful nuclear projects to mitigate perceived risks among investors. As various African nations, including Egypt, explore financing through international partnerships and innovative mechanisms like green bonds, the collective knowledge-sharing among countries will be pivotal in overcoming challenges and unlocking the continent’s nuclear potential.
