China to Pioneer Melt-Down Proof Reactors

pease1 writes "FT.com reports China is poised to develop the world's first commercially operated "pebble bed" nuclear reactor. If successfully commercialized, the pebble bed reactor would be the first radically new reactor design for several decades. It would push China to the forefront of development of a technology that researchers claim offers a new "meltdown-proof" alternative to standard water-cooled nuclear power stations." This was mentioned in September of last year but now looks as though the plan is moving forward.

Funny...

[daveschroeder]

Funny how it is, generally speaking, the same group of people who berate the US for our dependence on mideast oil, while at the same time vehemently protesting any movement down any path that might actually allow us to realistically release ourselves from some of that dependence, e.g., new nuclear plants. But no: must ... be ... scared ... of ... anything ..."nuclear" (including things like Cassini...)

Face it: from a standpoint of physics, wind, water, and solar, and the mechanisms for extracted energy from them, are NOT ENOUGH to sustain any semblance of the current lifestyles, right or wrong, without drastic and dramatic changes that would have far-reaching economic and social implications. We need to REPLACE the power sources we aim to wean ourselves from. And nuclear is the answer. Yes, there can be conservation. Yes, there can be debate. Yes, there can be compact fluorescents and LEDs. But those will only affect so much. Our energy requirements, as well as those of the rest of the world, are growing, and we should be leading the fucking way on the front of nuclear power, INCLUDING fusion, building new plants, and making a lot of investments in this area.

And we're simply not doing that. Fuck it: people say Social Security is the "third rail" of American politics? Energy policy is the power plant that electrifies it.

Perhaps China's communist regime has an advantage after all: they can actually do things that will be GOOD for their country, like building nuclear power plants without endless ranting and raving from protesters, and storing waste safely in places like Yucca Mountain (because having waste at ~150 temporary, insecure facilities is certainly better than having it at one site, imperfect as it may be).

I have never felt more unhealthy than when I was living within two miles of a COAL burning plant. Why the fuck are we still burning COAL for energy?

I lived within 35 miles (as the crow files) of a nuclear power plant. You know which one I felt safer around? The one that wasn't spewing tons of shit into the air.

Yeah, there's a small possiblity of something happening and people getting sick with a nuclear plant. It might even spread to other areas and affect those people's lives for generations. What bothers me is that there is a 100% possibility that the coal burning plant I was living near was spewing shit into the air that was unhealthy.

Since you are so afraid of nuclear power plants why don't you move yourself and your family within two miles of a coal burning plant?

Decomissioning waste

[grahamsz]

While this is a worthy achievement, and will certainly ease a lot of fears about third world countries operating reactors.

Unfortunately these reactors will still produce quite a bit of waste, and will still need to be decomissioned. Given how poorly the western world handles these issues, i can't imagine how well it'll be done elsewhere...

World balance of Power and Energy

[Corpus_Callosum]

The reason that the U.S. is not innovating in the area of energy production has to do with politics. America controls (directly and in the case of Saudi, indirectly) world oil production and therefore world energy. Alternate energy sources, especially those that free nations from the oil addiction reduce dependence on America and therefore reduce America's power.

China, knowing this, is actively persuing alternate energy policy including nuclear, hydrogen and more novel approaches. They want to detach themselves from the oil addiction so that they have independence from the U.S. and U.S. controled energy interests.

Again, politics.

But, the results are inevitable: As a result of these politics, the Chinese will inevitably control more advanced and more important energy technologies (both economicaly and ecologically). So the conclusion to this will be exactly the opposite of that desired by the status quo (America controlled energy). However, the administration doesn't care because they will be retired, rich, fat and happy (or dead of old age) when China turns it all around on America and effectively takes control of world energy production.

Least Bad

[Doc Ruby]

Americans, 5% of global population, produce over 30% of the output on 20% of the energy. We're very productive, and very efficient, compared with most of the rest of the world - vastly more efficient than any comparably sized group in either of those three measures. Of course, we're too wasteful, too - our economy hides the cost of our energy consumption. When we reduce our energy consumption, our economy will benefit, and lead the rest of the world to a more sustainable production system. But trashtalking our relative efficiency isn't the way to lead us there.

Re:Meltdown proof? Hah!

[jnaujok]

The "too cheap to meter" comment is addressed later in the comments, and was from one guy talking to a group of science-fiction writers in the 1950's. But yes, a real nuclear scientist said it, so I'll give you that.

On the other hand, in the U.S. Nuclear Reactors have killed how many civilians? So far as I know, the number of civilians killed in nuclear accidents at power plants is... zero. Yes, there have been deaths of workers, yes, you could argue that a few plants have leaked radiation here and there, but when you consider that the CDC is claiming 30,000 deaths a year from coal plants in the U.S., it makes for a hell of a weak argument.

Besides, the "safe" claim isn't even being made by the U.S. government, it's coming from China. As for me, I think nuclear is a great idea, and I'd rather be living 10 miles from Yucca Mountain than the 10 miles I currently live away from a coal plant that's rated one of the cleanest in America.

As for your "dirty bomb" statement, yeah, give it a try. Start by walking into a nuclear power plant, past the six layers of security. Then enter the core, ignoring the fatal dose of radiation you'll be bathed in. Grab hold of a few dozen pebbles, ignoring the heat that burns the flesh off your hands and arms. Take them home. Grind them up, again, ignore the fact that the fumes of the uranium or plutonium are among the most powerful and fastest acting poisons known to man. Use fluorine (a controlled substance also instantly fatal if breathed) to create UF6 to separate the Uranium from the graphite gas. Then use a million dollars of platinum to catylize the UF6 back to uranium metal. Stick it to 100 pounds of C4 and detonate it in downtown New York. Of course, the fact that you'll set off every airborne neutron detector that homeland security and the air force (and a half-dozen spy satellites) have before you leave your house might slow you down. Not to mention the continous man-hunt looking to find you.

You may not trust the government with this stuff, but consider the alternative. If there's one thing I'm not worried about in this country, it's how well our fissile material stockpile is guarded. When you realize that it takes three semis, twenty secret-service agents, the FBI and the army to move 20 grams of *spent* material to be used as the thermal warmers for the Pathfinder rover, you realize that the government is very serious about the security of this material.
