The DST/NRF SARChI Research Chair in Nuclear Engineering is the only research chair in nuclear engineering in South Africa. The aim of the chair is to do world-class research and contribute to the training of highly qualified nuclear engineers to serve the needs of the country. The main emphasis is on the new generation of light water reactors and high temperature gas-cooled reactors with improved safety and efficiency features. The team focuses on the computer modelling of the neutronics, heat transfer and fluid flow of the reactors and the associated systems. The chair collaborates closely with selected international and national partners such as the Korea Atomic Energy Research Institute and the Nuclear Energy Company of South Africa. Members of the chair are also involved in a research programme under the auspices of the International Atomic Energy Agency. The research outputs of the chair published in journal and presented at conferences enjoy wide spread international recognition. The chair has also made valuable contributions regarding the current debate on nuclear energy in South Africa.
