In the face of net zero targets and increasing energy security concerns, nuclear power is undergoing a revival. There are more than 50 reactors presently under construction worldwide, close to half of them in China and India. But as the new plants go up there is limited discussion of the huge costs and complexity of dismantling old plants and dealing with waste, which can remain radioactive for up to 300,000 years. A quarter million metric tonnes of spent fuel rods are believed to be spread across 14 countries worldwide, mostly collected in cooling pools at closed-down nuclear plants.
Some nuclear waste can be recycled. In France, a specialist plant can reprocess uranium, plutonium, and fission chemicals into new fuel. But critics point to the fact that the fuel can only be reused once, and the process itself creates yet more radioactive waste.
