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.

Nobody's saying that was said. There's no need to fall into an argument over the semantics of the comment.

I too found the statement odd. Even if 300 people die tomorrow from the events of the story, the statement about the western nuclear record is still true. It just doesn't seem to really fit the story.

I'm not anti-nuclear by any means, but the "western" statement read to me like they were trying a bit hard to find positive large-scale comments about nuclear power, and stretched to a statement that didn't really tie into the story.

> "I too found the statement odd"

Poorly-phrased, I agree. The point I was trying to make was that nations which operate Western-style reactors have an unbroken safety record. The world nuclear power industry falls into two basic camps: the "Western" style vs. the "Soviet-bloc" graphite-moderated design, one which is inherently much less safe.

From a standpoint of reactor design, Japan belongs to the former camp, not the latter.
