The UK government looks set to allow EDF to build a new kind of nuclear reactor at Hinkley Point. But are there better nuclear technologies we could use?
The UK’s first new nuclear power station since the 1990s is coming at the expense of renewable energy and leaving us unnervingly in hock to the Chinese.

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?
You need to take a wider view to work out the true greenhouse emissions from nuclear power.

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.

We cannot eliminate the inherent risks of nuclear power but it is rigorously monitored and has a proven performance of delivering zero-carbon electricity.
The Fukushima disaster was a dark chapter for nuclear power - but high-profile accidents are far from the only downside.

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.
Kudankulam is one of seven new nuclear plants being built in India.

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.
The Joint European Torus (seen here with a superimposed image of a plasma) is one of the machines helping to unlock fusion power.

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.
