What Australia’s nuclear shift means for minerals: Beyond uranium - Mining.com.au

The article examines Australia's emerging nuclear ambitions and the mineral supply chains they would require. Beyond uranium fuel itself, nuclear plants and grid integration demand lithium, cobalt, nickel, rare earths, and other processed minerals for reactors, control systems, batteries, and transmission infrastructure. The piece canvasses which of these minerals Australia produces or controls, where global supply chains concentrate, and what new extraction or processing might be needed to support a nuclear build-out.

Where this fits

This story bears directly on the materials and sovereignty pillar of whole-system costing. A nuclear grid avoids the staggering mineral throughput of a renewables-only transition: solar and wind require vastly more raw tonnage of copper, aluminium, and rare earths per megawatt-hour delivered over a plant lifetime. But it does not eliminate mineral dependence; it relocates and reshapes it. The question is not whether Australia needs minerals for energy security, it does, under any low-carbon pathway, but whether nuclear's mineral profile is more or less aligned with Australian extraction capacity and less exposed to Chinese processing monopolies than the renewables path.

What it means

Australia sits on substantial uranium reserves and can theoretically secure fuel supply. The harder question is processed minerals: China dominates rare-earth refining and lithium processing globally, a chokepoint that affects both nuclear and renewable grids alike. Any honest energy security strategy must map not only generation technology but also the full mineral and processing chain, including end-of-life recycling, to avoid trading fossil-fuel dependence for strategic-rival dependence in another form.
