China Goes Nuclear
Rei writes "Wired reports that the People's Republic of China has announced plans to build 30 new nuclear reactors by the year 2020, and by 2050 have almost as much nuclear power as the entire world produces today. The reactors are to be pebble bed reactors, in which helium replaces radioactive, pressurized water. A Chinese research institution demonstrated the safety of their test reactor against meltdown by shutting off the coolant."
I hope that China can help show the world what a viable source of clean energy nuclear power really is. The "danger" stigmatism that is attached to it is rediculous. The worst nuclear disaster in history, Cherynobl, killed a total of 3,000 people. That includes long term deaths attributed to radiation poisoning and increased cancer rates. Coal mining on the other hand kills around 30,000 people every year in mining accidents alone. Not to mention the pollution and enviromental damage that coal power plants generate. As for the nuclear waste generated aftewards there are a number of clever idea's about how to deal with it including one which disposes of it in the giant fusion reaction that is our Sun.

Yes, pebble bed reactors are very safe.
I just wish nuclear power wasn't politically dead in the USA. It's really the only way to replace all the coal and oil we burn to produce the huge amount of electricity we use.
the antinuclear crowd doesn't seem to understand how advanced nuclear technology is today
these pebble bed reactors just can not melt down, the design is such that their no possibility of a run away self-sustaining chain reaction taking hold
do antinuclear types like the alternative? middle east conflicts fueled by oil prices? air pollution and smog?
and proponents of green energy do not seem to understand their science: you can't scale up geothermal, wind, solar, tidal, ocean thermal gradient, etc, to meet one tenth of the modern world's energy needs
the much vaunted vaporware hydrogen promise: where do hydrogen proponents think the hydrogen comes from? i don't know why people don't understand such a simple concept: you need to spend more energy freeing hydrogen from water or hydrocarbons than anything you gain from using it as an energy medium
biodiesel sounds interesting to me, and fusion is always the holy grail, but these are unproven technoogies today... if you are a true green energy believer, then get to work here, and roll up your sleeves working on fusion or biodiesel: this is where the most promise lies for your efforts
and of course, the "just use less energy" crowd: when you figure out how to tell people to stop using gas and nuclear and start riding bikes, get back to me
meanwhile, i applaud the chinese, they see the writing on the wall: an overactive economy, demanding more and more gas and coal, and skyhigh oil prices and a volatile middle east... for the chinese, a pebble bed reactor commitment is a no-brainer
now if only the nimby types in the us could understand the wisdom of embracing pebble bed nuclear energy to combat reliance on middle east oil
but of course, simple fear of the unknown and ignorance of simple tech means the us will be left dependent on volatile undependable oil and gas and coal, while the chinese enjoy a safe, stable, cheap energy source
apparently, the nimby crowd in the us sees less risk in sending their sons and daughters to iraq than building a nuclear reactor of new design without any chernobyl or 3 mile island implications
this is not silkwood or the china syndrome folks, the stakes are accutely high in today's world: adjust your antinuclear opinion appropriately please
intellectual property law is philosophically incoherent. it is your moral duty to ignore it or sabotage it
I think this is a much much better solution for them, both economically and especially environmentally. There were stories that they could only ramp up the turbines from stop(a process that took about 6 hours) at night, because the resulting ploom of yellow sulfur smoke couldn't be seen. Once the burner was at full temperature by dawn, no more yellow smoke, and thus no more concerned citizens.
The place which falsified QA records for years and dumped waste into the Irish Sea?
I keep hearing stories about the Japanese working on some type of orbital projectile launcher, same type of thing Gerald Bull was working on before his untimely death. I don't know if they are true, but this would provide a safe way of getting non-human cargo to orbit without the risk of explosion. Encased blocks of radioactive waste could be shot to orbit, then nudged towards the sun by an orbiting sat.
How about the space elevator I keep hearing about here on Slashdot?... No explosive danger there either! Small/medium sized containers could be hoisted to orbit, then directed towards the sun with just a little force. Could make the containers or lift cars with some type of balistic parachute too, so if the cord breaks, the containers land safely in the sea where they can be recovered without exposure.
I'm not too fond of the idea of exploding radioactive bottle-rockets, but the way things are going, we may not have to think like that for too much longer. There are lots of new technologies that could help us safely get our waste to the sun. Best part about that...it's not on earth anymore! No need to worry about theft from the terrorists now and no need to worry about warning the the rabbit-people 50,000 years from now. Yucca mountain may just become a "low-level" waste type site for materials that just don't need to be hoisted to the sun, like all those slightly used Tyvec suits and minimally contaminated whatnot.
The idea of putting our nuclear waste on the sun isn't so far fetched. We just need to come up with a safe way of handling it until it gets there.
We can't live without it at this time.
REALITY 2:
All the plants in this country have run past their intended design lives, AND are 30-40 years out of date with modern technology.
REALITY 3:
Modern bead reactors of the type the chinese are building are VASTLY less likely to meltdown than any reactor currently running in the US. The coolant in a bead reactor actually catalyses the reaction, so without coolant, there is no reaction.
People in this country are totally irrational when it comes to nuclear power. We need this stuff, if only to replace the seriously aging reactors we already have. This is one place where I want to beat the snot out of all the left-wingers who won't be happy with anything that doesn't run on fairy dust and pot.
ad logicam Claiming a proposition is false because it was presented as the conclusion of a fallacious argument.
OT, but China is not so much communism as authoritarianism. Yes, the communist party is in control and yes the propoganda is alive. But communism implies more than simply a government - it's a social structure.
You ask who cares?
Well, China is playing a game of accepting limited market economy while still controling many economic things, including some prices, as it sees fit. China is accepted by business interests because it has made committments to the WTO and other institutions. However, it is still classified as a developing country and therefore gets a lot of slack from the WTO. This also means it gets a lot of development loans at great rates and other things. If all it did was preach communism, it would not be in this position. There have been real changes in China, some incomplete, but many progressive.
Regardless, Lenin, Mao, Marx, etc. would probably not consider current China (PRC) communist. If communism to you means a socialist state controlled by one party of elites and the military interactive in the market economy, then yes it is. Otherwise, I wouldn't so easily label it.
You can bury it in the Canadian Shield. They've studied it and 10,000 years is miniscule compared to how stable that is. Solid granite for thousands of meters. Drill, Drop, fill it in. It won't go anywhere for eons.
