2012 - A Roland Emmerich film |
Even the elements appear to have turned against the emergency operation. The wind, which had been blowing out to sea, changed direction and is now blowing the radiation towards Tokyo, a city of 28 million people. The strength of the wind is also stopping the authorities using helicopters to cool the reactors by dumping water from the air. Despite the continuing assurances you know how bad things have got when a Japanese 'John Kettley' has to play a crucial role.
The crisis in Japan, however, has put a stop to another nuclear explosion. Around the world governments had persuaded their populations that nuclear fuel was 'clean' energy and the best fix to address energy requirements in the context of falling oil reserves and climate change. New reactors have been given the go ahead around the world. Even Sweden, who had enforced a ban on building nuclear reactors for the last 30 years, had given the go ahead for new plants.
However, the footage coming out of Japan appears to have caused a rapid change of heart. A number of governments have acted swiftly to reassure their public. Germany has closed its seven oldest reactors and is discussing becoming nuclear free by 2020, Switzerland has suspended plans to build three more reactors and the Austrian Environment Minister, Nikolaus Berlakovich, has called for stress tests on all of Europe's 143 nuclear power stations to ensure they can withstand earthquakes.

Huhne claimed safety was a "very high" priority for the industry and existing procedures were "extremely effective". He went on to stress "there are major differences between our situation and the Japanese situation, both in terms of luckily not being in an earthquake zone and not suffering the secondary consequences of the tsunami, there may be parallels in how robust our back-up systems can be - for example when it comes to the diesel generating electricity powering our cooling systems."
Tory MP Tim Yeo, Chair of the Energy and Climate Change Select Committee, dismissed the discussions about safety as "hysteria". He has called for officials to do more to remind the public of the UK's "incredibly safe" nuclear record. Yeo's constituency, South Suffolk, is the site for the Sizewell B nuclear power station and he has a record of opposing wind turbines. He is Chairman of a company developing alkaline fuel cells.

While Germany has decided to close its oldest power stations, in the UK, EDF, yes the same one criticised for safety, announced they intend to extend the lives of two power stations by five years. The two reactors, in Hartlepool and Heysham have been running at a reduced capacity since safety issues were discovered with the boilers attached to the reactors back in 2007. Reassured?
Back in 2006 Alastair Darling, then Industry Secretary, announced the go ahead for eight new nuclear power stations to be operating by 2018. At the time the Conservatives argued that nuclear power should only be used as a 'last resort', while the Liberal Democrats, including Huhne, accused Labour of "surrendering" to the nuclear lobby. How things have changed. By August 2010, Chris Huhne, the Lib Dem MP and now cabinet minister, was assuring the House of Commons that the eight power stations were on schedule.
However, Huhne's statement was primarily concerned with funding not safety. According to the Independent, Mr Huhne said it was "clear" that MPs would vote in favour of new nuclear power stations providing there was no public subsidy involved. "I don't think you can determine whether a government is serious about energy policy merely in terms of whether it is prepared to write very large cheques. It has always been clear that our next generation of electricity power stations are going to be built by private investors with a framework put in place."

The BBC reported that 'the nuclear industry insists existing plants are built to withstand "credible seismic scenarios". What are 'credible seismic scenarios'? According to the Wall Street Journal, Tokyo Electric who operate the nuclear plants currently threatened with meltdown, said in safety documents that 7.9 was the highest magnitude for which they tested in Fukushima. 7.9 was calculated to be the worst case scenario for 'simultaneous seismic activity along the three tectonic plates in the sea east of the plants' - the epicentre of the latest quake. The Sendai earthquake on 11 March measured 9. This is the fifth largest earthquake ever measured, but since 1923 their have been five earthquakes in Japan above 7.9. Worrying definition of "credible" isn't it?
Meanwhile, in the UK, the nuclear lobby are fighting back. Huhne is arguing, correctly, that the UK has completely different geological conditions to Japan. Engineering experts have told the BBC that the new British reactors will be 'designed using more advanced technology - specifically not requiring power sources such as generators to cool them after a emergency shutdown - making them "inherently safer".' I am sure they are also correct and I don't doubt that the Japanese engineers made similar claims about their own technology. But we should not be deceived into thinking the argument is about whether we can address the lessons of this latest disaster.
Steve Campbell, from Greenpeace, got to the heart of the matter when he said, "Japan's nuclear plants were built with the latest technology, specifically to withstand natural disasters, yet we still face potential meltdown," Why? The Japanese were confident they had considered all the risks but a series of events led to unpredictable and extreme outcomes. The earthquakes, tsunami, no doubt 'human error' and eventually even the wind changing direction are all playing a part in this story.
It may be stating the obvious, we can reduce but never remove risk entirely. Isn't it ironic that in a society that is wrapping its population in health and safety legislation our politicians can accept the risks of nuclear power so easily? Yet the consequences for getting it wrong, as we see in the footage from Japan, threatens millions. 25 years after the disaster in Chernobyl - it is still the most polluted place on the earth.
What is the appropriate risk when so much is at stake? In such an unpredictable world, the only predictable thing is that this won't be the last disaster. Can we afford to keep gambling?
Ah, don't you just love Spring, look at that beautiful butterfly flapping its wings...
