Fukushima has three nuclear reactors exposed and four fuel cores exposed," he said, "You probably have the equivalent of 20 nuclear reactor cores because of the fuel cores, and they are all in desperate need of being cooled, and there is no means to cool them effectively.

TEPCO has been spraying water on several of the reactors and fuel cores, but this has led to even greater problems, such as radiation being emitted into the air in steam and evaporated sea water - as well as generating hundreds of thousands of tons of highly radioactive sea water that has to be disposed of.

"They are pouring in water and the question is what are they going to do with the waste that comes out of that system, because it is going to contain plutonium and uranium. Where do you put the water?"

Dutch energy executive Peter Terium is the most likely successor to RWE chief executive Jürgen Grossmann, according to company insiders cited in German news reports. Grossmann, whose contract expires at the end of September 2012, defended RWE's investments in nuclear power plants vigorously but unsuccessfully against government plans to phase out atomic energy by 2022. The 59-year-old's lobbying earned him the nickname "Atom-Rambo" and even prompted Germany's Nature and Biodiversity Conservation Union to award him the dubious title of "Dinosaur of the Year 2010."

News that Peter Terium, 47, is likely to be the fresh face to replace Grossmann surprised many observers. But the dark-horse candidate has been with RWE since 2003. He first RWE Supply & Trading and later oversaw the takeover of Dutch energy company Essent, which he currently heads.

Reinventing the wheel Hubertus Bardt, an energy and environmental policy expert at the Cologne Institute for Economic Research, said Grossmann shouldn't be faulted for aggressively defending his company's substantial investment into nuclear power

This nation has recovered from worse natural – and manmade – catastrophes. But it is the triple meltdown and its aftermath at the Fukushima nuclear power plant 40km down the coast from Soma that has elevated Japan into unknown, and unknowable, terrain. Across the northeast, millions of people are living with its consequences and searching for a consensus on a safe radiation level that does not exist. Experts give bewilderingly different assessments of its dangers.

Some scientists say Fukushima is worse than the 1986 Chernobyl accident, with which it shares a maximum level-7 rating on the sliding scale of nuclear disasters. One of the most prominent of them is Dr Helen Caldicott, an Australian physician and long time anti-nuclear activist who warns of "horrors to come" in Fukushima.

Chris Busby, a professor at the University of Ulster known for his alarmist views, generated controversy during a Japan visit last month when he said the disaster would result in more than 1 million deaths. "Fukushima is still boiling its radionuclides all over Japan," he said. "Chernobyl went up in one go. So Fukushima is worse."

Dr. Yvres Guenon from AREVA gave a good pitch at the recent SANEA talk on “The nuclear program is a true opportunity for South Africa. He started off stating that we weren’t alone in the energy epidemic; “don’t think you are the only country with bad decision makers” he said. Europe is in the same boat. In the past countries went coal as it was the only option, but in the future it will be about finding the ‘right mix’ of energy producers. Guenon’s solution is to include nuclear power in that mix.

The argument was a fair one – nuclear does have financial benefits to it. The cost might be a bit hefty in the beginning; but most (if not all) energy providers are. The one thing about nuclear is that the price of energy thereafter doesn’t change. What you pay today for your electricity will stay that way for the next 50 – 60 years. In his presentation he included a diagram that showed nuclear was the least in greenhouse gases. Europe doesn’t have many options for energy development but here in South Africa, where we are blessed with sun and the south-easter wind, we have a variety. Even though we can include renewable in our mix, Guenon showed that solar costs 10 times more than coal and wind was four times more.

Guenon’s main purpose of his presentation was also the job development and therefore economy improvement, that comes from nuclear power. As nuclear involvers building an entire plant consisting of a variety of technologies and includes a variety of industries there is huge potential in employment and expansion in industries. Other energy producers, such as solar or wind, involve a slice of professions and specific exclusive industries. Nuclear touches on engineers, technicians, welders, management and a wide variety of workers. When asked about the chances of an accident, Guenon simple answer was “about the same chance of a meteorite landing in your lounge.” It creates abundant energy at a fraction of the price, while creating job opportunities and improving the economy; all of this and to top it off – no coal. On the outside it seems to provide the answer to all our problems. So what’s the catch? “Dr Guenon!” A hand shot up in the audience. “What about waste?”
