The world's largest nuclear power plant demonstrates inherent safety

Those opposed to nuclear power have long raised doubts over its safety.  Often raised is the question, "what would happen if major earthquake struck one?"  Would a radioactivity release endanger millions?  

This morning, we got a chance to find out. A 6.8 earthquake struck northern Japan, almost directly underneath the massive Kashiwazaki-Kariwa Plant, responsible for a third of the Japanese residential electricity supply. The quake leveled hundreds of homes, left fissures 3 feet wide in the ground, and swayed buildings in Tokyo, 300 km away.

What happened at the plant itself? An electrical transformer caught fire and was quickly extinguished. And a tiny amount of mildly radioactive water was released -- one billionth of the safe amount allowed under under Japanese law, or 1/1,000,000 of what is generated from a single dental x-ray. Not even the workers actually inside the reactor were exposed to a dangerous dose, much less the general public. All reactors were shut down for inspection purposes, and initial reports indicate no damage or safety issues. 

And that's it.  Nothing to see here folks, move along.

The western world's nuclear safety record remains unbroken. Over five decades and thousands of reactor-years later, not one person has ever been harmed by commercial power generation. Nuclear power generates no greenhouse gases, and operating costs continue to drop, reaching a level of 1.66 cents per kilowatt-hour in 2006 -- one twentieth the cost of solar power. Despite all this, the U.S. and most of Europe continue to shy away from nuclear power, and pursue pie-in-the-sky energy approaches that, even if they eventually become feasible, will remain forever more expensive to operate.

The West may be ignoring nuclear power, but others are not. Last year, China announced plans to build 30 new reactors, in a bid to reduce air pollution and provide cheap power for its burgeoning economy.

Energy production is always 'potentially' dangerous.

Just to add some numbers to that, there have been 31 people known to have been killed from wind power. Mostly these have been people installing or doing maintenance on the turbines, however they also include a skydiver that landed on a turbine and a crop-duster pilot that was killed when his aircraft hit a guy-wire for a wind farm meteorological station.

Depending on what estimate for number of deaths from the Chernobyl accident (which range from the 41 known deaths to as much as 200,000 if you take Greenpeace's figures), the numbers may be quite close in terms of deaths/TWh. ie if wind power was as widespread as nuclear we could expect about as many people to be killed by wind power as by nuke power INCLUDING Russian-style reactors with the Chernobyl accident.

Hydro power and coal power both come out MUCH worse then nukes or wind power in this regard. Hydro power has by far the highest number of deaths/TWh from accidents (the bulk of which have happened in China) while pollution coal power is known to be killing many tens of thousands every year just through regular use. A recent report gave a very rough estimate of over 400,000 deaths/year in China for coal power plant pollution, while North American numbers are usually in the 5,000-30,000 deaths/year.
