Well look at that...someone can write an article that doesn't follow the Alex Jones "it will kill us all!!!" theme;


Three places: Three Mile Island, Chernobyl, Fukushima. And three more: Banqiao, Machhu II, Hiakud. Most people react with horror to the first trio, while the second three locations usually draw a blank look. In fact, the latter were the sites of three major hydroelectric dam failures: in China and India in 1975, 1979 and 1980, which were directly responsible for the deaths of tens of thousands. In contrast, the death toll directly associated with radiation exposure from the three best-known civil nuclear accidents is estimated by the World Health Organisation to be conservatively about 50, all associated with Chernobyl.
Nuclear power has had a pretty bad press recently. In the post-Fukushima world, major power companies such as the German-owned E.ON and RWE-npower have taken the decision not to invest in building new nuclear power stations in Britain, citing costs in the current economic climate.
Some activists argue that the economics of construction and operation of nuclear power stations are sufficiently prohibitive that increased investment in safe, renewable power supplies such as offshore wind projects are a more attractive option.
But why is nuclear power now so expensive? I suggest that it is at least partly due to an inflated analysis of the potential health risks associated with civilian nuclear waste in particular, and an exaggerated assessment of “nuclear risk” in general.
It is true that the management of waste reactor fuel is a significant fraction of the overall costs, but if nuclear waste disposal were calculated in proportion to the actual risk associated with the hazard, the prohibitive economics of nuclear power would be reduced significantly.
Indeed, “nuclear risk” is in a category all of its own, as was seen all too clearly last year when a major natural disaster, the Tohoku earthquake, which killed tens of thousands of people, was quickly overshadowed in the global collective consciousness by the consequent nuclear incident at the Fukushima plant, which killed no one.
A number of countries, most notably Germany changed their national energy policy with regard to the future development of civilian nuclear power.
The public reaction to Fukushima and the response compared with other energy-related disasters raises the question: what is it specifically about nuclear power issues that provokes such a strong response?
It was back in the Thirties that Otto Frisch and Lise Meitner showed that splitting a heavy uranium nucleus into two lighter elements, such as strontium and xenon, resulted in the release of millions of times more energy per atom than burning coal.
Nuclear technology then rapidly expanded as a result of the Manhattan Project, with the construction of superweapons capable of unleashing the explosive power of uncontrolled nuclear fission and, later, fusion. Iconic images of mushroom clouds became fixed in our minds following the devastations of Hiroshima and Nagasaki. And so, for many, civilian nuclear power and images associated with nuclear weapons remain intimately linked.
I believe that this emotional link between defence and civilian applications of nuclear technology constrains a rational, scientific analysis of the uses and relative benefits of nuclear power. Certainly, fears of the biological effects of invisible radiation can lead to some bizarre behaviour.
The Italian foreign ministry, for example, recommended that its citizens flew out of Tokyo to avoid potential radiation exposure in the first couple of weeks following the Fukushima leak. While the radiation levels in the Japanese capital rose significantly above normal, they remained lower than the typical average background radiation levels in Rome, leading to the bizarre situation of individuals being relocated to places with higher radiation levels than those they were leaving.
And a pervasive myth has taken hold that even tiny amounts of radiation are unsafe. In reality, this cannot be so, as humans have evolved in an invisible sea of naturally occurring radioactivity. Much of this arises from radioactive forms of potassium, uranium and thorium; remnants of the Earth’s formation more than 4 billion years ago. Human bodies are bubbling with radioactivity, with around 7,000 atoms decaying each second due to radioactivity from potassium-40 and carbon-14.
Our understanding of the biological effects of radiation has been developed over more than 80 years, following the first meeting of the First International Congress of Radiology in London in 1925. Radiation-induced effects such as radiation sickness were noted to occur with exposure to specific organs only above a well-defined threshold dose. As to cancer, the probability of a malignant tumour arising is thought to be related to the quantity and type of radiation to which an individual has been exposed.
The cohort of Japanese bomb survivors who were exposed in 1945 are the standard baseline for radiation-induced cancer effects in humans, and the majority of the data on the long-term effects of radiation on humans comes from detailed studies of this group. Perhaps surprisingly, of the 87,000 individuals in this cohort more than 30,000 were still alive 55 years after Nagasaki and Hiroshima.
This group showed approximately 10,000 deaths from leukaemia and other cancers up to the year 2000, but it has been estimated that only approximately 500 of these individuals died from cancers associated with their radiation exposure to the atom bombs.
There have been three major accidents in nuclear power production in more than 14,000 “reactor years” of operational, civilian nuclear power. The reactor core meltdown at Three Mile Island in 1979 made headlines but the melted fuel remained contained within the main reactor vessel, with no measurable radiation health consequences.
At Chernobyl a steam explosion blew out the reactor-holding vessel, the reactor core caught fire and a radioactive plume belched into the atmosphere for 10 days, with an estimated 5 per cent of the entire reactor core released. Twenty eight people, mostly firefighters, died within a few weeks of exposure from acute radiation syndrome. According to the World Health Organisation, an additional 19 died between 1987 and 2004 of cancers which might have been radiation-induced.
In the 20 years following 1986, no statistically significant health effects on the wider population could be correlated to caesium-137 exposure from the Chernobyl release.
But it is what to do with radioactive waste that remains a major and emotive issue in the minds of the public and politicians alike. Although some elements in spent fuel waste can remain radioactive for many thousands of years, the safety issues here seem to be political, rather than technical. Indeed, nature provides excellent examples of nuclear waste storage, with the example of the Oklo natural reactor in Gabon. Geological examination of this area shows evidence of an ancient, naturally occurring nuclear reactor within the uranium-rich mineral deposits which operated approximately two billion years ago. The radioactive “waste material” from the natural reactor at Oklo appears to have migrated less than 10 metres from where it was formed.
If this is what happens in nature’s random geological disposal site, a carefully chosen, geologically stable deep storage facility for vitrified nuclear fuel waste would seem safe to me. Civilian nuclear power represents approximately one sixth of the world’s current electricity production, operating in more than 30 countries.
Interestingly, while the civilian nuclear programmes have their ups and downs, fundamental nuclear physics research has never been more vibrant.
The danger for future generations is that our residual, Cold War-based fear of radiation means that we face an uncertain future, reliant for our energy needs on coal, imported gas and unproven technologies such as carbon capture and offshore wind farms. Meanwhile Britain’s carbon reduction targets remain as unattainable as ever.
Our irrational fear of the atom stands in the way of the development of nuclear power and its potentially vital contribution to the long-term energy needs of an ever-increasing and energy-greedy world population.

Do you think Alex Jones would ignore a fearmongering plum as sweet as the NUKE-U-LER DEATH! gimmick?

Nobody's listening. It's too long, it's too complex, and it has a ".co.uk" at the end of the link. It's easier to just go with blind panic.

Bzzt. Wrong. Alex is a huge nuke fearmongerer. And Gore cites the cost issue just like the article.

Couric: What about nuclear power? I ask, what about nuclear power, because countries like France get something like 75-to-80 percent of their power from nuclear.

Gore: France is unique. It's a special case. We have a lot of nuclear plants in the U.S., and … I'm not anti-nuclear. I'm a little skeptical that's it's gonna play a much bigger role than it does now. I think it'll continue to play a role. But the problems with nuclear are it's very expensive. It takes a long time to build. And these nuclear plants only come in one size, extra large.

And utilities don't want to commit all that money for 15 years to get a plant that's rising in cost. And of course the fuel also has some problems, because if it gets out to other countries that can't be trusted, it feeds the problem of proliferating nuclear weapons.

Couric: Do you also worry about nuclear plants being potential targets for terrorists?

Gore: Yes, I myself, I don't think of that as a bar to nuclear power, because there are a lot of things that are potential targets, and we need to equip ourselves … to protect them. It's one of the problems, for sure, the nuclear waste storage issue is one of the problems. But I think the bigger problems are the cost, the long time for construction, and also the problem that if other countries make a massive commitment to it, we make the problem of nuclear weapons proliferation worse.

That's interesting, because a large part of the cost in nuclear power is the regulatory bullshit associated with nuclear power...

Rogan is completely irrational about nuclear power too. When that shit comes up, I just skip five minutes ahead so I don't have to waste my time listening to 5th grade scare tactics.
