Nuclear power can’t save us from climate change if it’s too hot

 

In November 2007, Anne Lauvergeon, President and Chief Executive of French nuclear energy incompetents Areva boasted

In a world enjoying a growing energy thirst, we have in our hands nuclear energy: a formidable asset to build an energy sustainable future. It means that one of the answers to the issues of achieving security of supply, competitiveness and the fight against climate change is already available to us.

Nuclear energy can already help us against climate change?

Oh really?

Tell that to the French government who are this summer are being forced to import electricity from the UK because its inland nuclear reactors cannot operate properly in the summer heatwave

Fourteen of France’s 19 nuclear power stations are located inland and use river water rather than seawater for cooling. When water temperatures rise, EDF is forced to shut down the reactors to prevent their casings from exceeding 50C […] One power industry insider said yesterday that about 20GW (gigawatts) of France’s total nuclear generating capacity of 63GW was out of service.

Yes, this amazing, cheap, reliable and safe technology that is going to save us from rising global temperatures can’t work when the temperature rises. Really. The world’s major exponent of nuclear power, the one that is supposedly going to lead us the promised land of a nuclear ‘renaissance’, is having to import electricity because its own reactors aren’t up to the job. Nuclear power is supposed to save us from climate change but can’t work when the climate changes. That’s what they call a Catch-22.

With temperatures only set rise in the coming years, it looks like France has a big problem. And they’re not alone. There are over 400 nuclear power plants across the world. How many are inland and rely on river water for coolant? Not that coastal reactors are any better. Look for example at the CanDU facility in Ontario, Canada which is actively contributing to climate change.

So what’s the solution? In France, desperate times demand desperate measures when a country is so reliant on nuclear power…

EDF must also observe strict rules governing the heat of the water it discharges into waterways so that wildlife is not harmed. The maximum permitted temperature is 24C […] In 2003, the situation grew so severe that the French nuclear safety regulator granted special exemptions to three plants, allowing them temporarily to discharge water into rivers at temperatures as high as 30C.

Can these strict rules governing reactors’ discharges survive in the face of rising global temperatures? One would imagine not. In other words the nuclear industry will be allowed to damage the environment more than it already does.

‘In order to save the planet we must destroy it,’ should be its new slogan.
