Nuclear Energy

Nuclear energy is the power generated through nuclear reactions, primarily nuclear fission, in which the nucleus of an atom is split to release large amounts of energy. The technology harnesses this energy to produce electricity in nuclear power stations, where controlled chain reactions heat water to create steam that drives turbines connected to generators. Nuclear fission typically uses uranium-235 or plutonium-239 as fuel, with the fuel rods housed in a reactor core surrounded by control rods and coolant systems to manage the reaction rate and temperature. Nuclear energy is a low-carbon baseload power source capable of generating electricity continuously at high capacity factors, making it attractive for countries seeking to reduce greenhouse gas emissions while meeting growing energy demand. The technology is capital-intensive, requiring substantial upfront investment in reactor construction, safety systems and regulatory compliance, but offers relatively low operating costs once commissioned. Nuclear power accounts for about 10% of global electricity generation and remains a significant component of the energy mix in countries including France, the United States, China, Russia and South Korea. Safety concerns following major accidents at Three Mile Island, Chernobyl and Fukushima have shaped public perception and regulatory frameworks, leading to enhanced safety protocols and the development of advanced reactor designs with passive safety features. Proponents emphasise nuclear energy's role in decarbonising electricity systems and providing energy security, while critics highlight challenges including radioactive waste management, high capital costs, construction delays and the risk of nuclear proliferation. Emerging technologies such as small modular reactors and Generation IV designs promise improved safety, efficiency and flexibility, potentially expanding nuclear energy's role in the global transition to low-carbon energy systems.

ASP Isotopes unit targets domestic uranium conversion

Quantum Leap Energy (QLE), a subsidiary of JSE- and Nasdaq-listed ASP Isotopes, has signed a research agreement with the Texas A&M University Engineering Experiment Station to advance commercial production of high-purity uranium hexafluoride, the feedstock required for uranium enrichment. QLE CEO Dr Ryno Pretorius says the US currently has only one operating commercial conversion facility, making expanded domestic capacity essential to energy security, with the collaboration aiming to improve production efficiency, cut costs and support a more resilient nuclear fuel supply chain.

US firm targets seawater as new uranium source

Texas-based SuperCritical Materials has won an exclusive US Department of Energy licence to extract uranium from seawater using treated acrylic fibres, aiming to shift the United States from a net uranium importer, sourcing up to 75% of enriched uranium from Russia, France and Germany, to a net exporter. The company targets a first plant producing 839 150 kg of uranium a year from 2030 or 2031, and plans a Nasdaq listing this year.

NRWDI advances R2-billion spent-fuel storage plan

South Africa's National Radioactive Waste Disposal Institute now fully operates the Vaalputs facility after securing its licence from Necsa in July 2025, and has completed preliminary design for a R2-billion Centralised Interim Storage Facility targeted for 2030, ahead of a Deep Geological Repository planned by 2065.
