Even the biggest proponents of nuclear power can’t ignore 10,000 metric tons of spent fuel globally every year. What if we could recycle every last atom of nuclear waste?
Nuclear power isn’t ‘zero-emission’, as many proponents claim. Factor in uranium mining, power plant construction, and other factors and it has similar emissions to wind power. But that’s still lower than fossil fuels.

The basics of fission physics have stayed the same over the decades. But power-generating reactor designs have evolved, turning to new coolants, recycled fuel and other innovations.
We cannot eliminate the inherent risks of nuclear power but it is rigorously monitored and has a proven performance of delivering zero-carbon electricity.
Is nuclear power worth it? No, says Mark Diesendorf – it’s never been a major world energy force, it has caused huge accidents, and its greenhouse emissions are higher than many people realise.
Asia and Eastern Europe are leading the way, but construction times for new projects are getting longer, and Europe’s dominant energy player, Germany, is turning its back on nuclear.
Through history, nuclear power has gone hand in hand with the nuclear arms race. But does it have to be this way? Closer international cooperation can help nations embrace nuclear power peacefully.
Why don’t we have nuclear fusion power yet? Because it involves taming plasmas at temperatures far hotter than the Sun’s core. But the good news is that physicists are slowly but surely figuring out how.
