Resurrecting the HTGR Capability in South Africa
Repositioning South Africa at the forefront of advanced nuclear innovation through the revival of High Temperature Gas Reactor capability.
The North-West University (NWU) and the South African National Energy Development Institute (SANEDI) share a strategic partnership focused on advancing energy research, innovation, and skills development in South Africa.
Within this project, NWU serves as the research implementation partner, while SANEDI provides strategic direction and alignment with national energy priorities. Through this partnership, academic expertise is connected with national energy priorities to ensure that research outputs are not only technically sound, but also relevant to South Africa’s broader development goals.
This collaboration bridges the gap between academic research and practical application, enabling the translation of scientific knowledge into policy-relevant outcomes. It also supports capacity building by developing critical nuclear and energy skills within South Africa.

The project creates a platform for technical assessment, stakeholder alignment, and the development of recommendations that can support future decision-making in the advanced nuclear energy sector.
Building on the legacy of the PBMR programme, South Africa holds unique intellectual property, infrastructure, and technical expertise that can be reactivated. As global momentum grows around Small Modular Reactors, this project strengthens energy security and global positioning.
By assessing existing capabilities and identifying gaps, the project contributes to a practical roadmap for rebuilding South Africa’s HTGR capability and positioning the country within the advanced nuclear technology landscape.

Research Aim
The research aimed to determine how South Africa can revive its HTGR capability by assessing existing assets, identifying gaps, and developing a roadmap toward deployment and competitiveness.
Strategic Impact
Energy Security
Reliable and scalable nuclear solutions can strengthen South Africa’s long-term energy stability. By reviving HTGR capability, the country can support a more diverse and resilient energy mix.
Skills Development
The project supports the rebuilding of technical expertise in South Africa’s nuclear and energy sectors. It creates opportunities for research training, knowledge transfer, and specialised engineering capacity.
Global Positioning
Reviving HTGR capability can position South Africa as a meaningful contributor to advanced nuclear technologies. It also opens opportunities for participation in the growing global Small Modular Reactor value chain.
Future Outlook
Reviving the HTGR capability is about shaping South Africa’s energy future through innovation, resilience, and long-term impact. The project provides a pathway to reconnect existing knowledge, infrastructure, and technical expertise with modern energy priorities.
By aligning with the Just Energy Transition and national energy strategies, this initiative can support sustainable industrial development, strengthen local capability, and contribute to South Africa’s role in the global nuclear innovation landscape.
