Are Lefties (Re-)Embracing Nucular Power?

Expanding nuclear power is only one piece of the energy puzzle. But it is a piece we cannot afford to dismiss.
The reason is clear. Electricity demand is rising -- some say by as much as 50 percent during the next 30 to 50 years.
That's from an op-ed in today's SF Chron by the always-interesting G. Paschal Zachary (author of the wonderful book from a few years back, The Global Me). In "The Case for Nuclear Power," Zachary recounts a youth spent protesting nuclear power plants and catches the reader up on how nuke tech is better, safer, etc. It's well worth reading and is online here [*link fixed finally!].
As is the original Port Huron Statement, put out by Students for a Democratic Society, on this score. It takes nuclear power for granted ("whole cities can easily be powered" by it, even as the authors worry about nuclear weaponry; the full text even argues that "our monster cities...might now be humanized [and] broken into smaller communities, powered by nuclear energy) [updated link].
And so are the remarkable--and generally underreported--accounts of the long-term damage done by Chernobyl, the biggest nuclear accident to date. As the Wash Post glossed last year's authoritative UN study on the matter, the effects "were far less catastrophic than feared."

Uhh yeah geek, real safe. The "pebbles" are tennis ball sized fuel pellets coated with graphite, the stuff used as a moderator in the chernobyl reactor.
New reactors have steel too. Steel was used at Chernobyl. Scary.
Anyway, there is indeed a difference between having a huge block of regular graphite that can catch on fire and a thin coating of pyrolytic coating that melts at 3000 degrees C.
That's the new "safer" design proposed by advocates for new nukes.
No. Pebble bed gets the most press of new designs, but most nuclear engineers in the US are betting on other high temperature designs. In addition, the plants that will be built in a decade's time will still be Generation III PWRs, like those beginning to be built around the world today. No radical changes in these new plants.
If the water in the pools is drained or removed in another manner (by terrorist incident for example) 7 to 18 times the radiation released at Chernobyl will billow into the atmoosphere.
Source? NIRS? Greenpeace?
I did my thesis work on zirconium alloys in nuclear power plants, though not specifically on the potential for a Zircaloy fire in a drained spent fuel pool. I do know this:
- Once the fuel has been allowed to decay for five years or so within the pool, the amount of decay heat is not high enough to cause a Zircaloy fire even if the fuel is completely uncovered.
- The NRC calculates the risk of spent fuel being uncovered and the fuel being ignited
here. 2.2 x 10^-6 per reactor year.
Obviously reprocessing or Yucca Mountain would both serve to greatly lower this risk.
Will the evacuation plans for the population around these potential disaster areas be as effective as the Katrina evacuation? No one knows or seems to care.
Another scare tactic, conflating it with Katrina. Of course people care and look into the issue carefully as part of their jobs. Would the mistakes of the Katrina evacuation be repeated? I don't know. But this is not a proplem unique to nuclear power. if a chemical plant or oil refinery explodes, evacuations are also only as good as government planning. And in the case of a nuclear accident, an evacuation might not always be the prudent choice.

There seems to be more pessimism around here with respect to renewable alternatives that I feel is warranted. Yes, renewables (wind, solar, geothermal, tidal, biomass for electricity; biodiesel, methanol, ethanol, etc, for liquid transport fuel) have been pie-in-the-sky for decades. There was an obvious reason for this - they were much more expensive than the petro alternative. However, it doesn't take a genius to see the trends - renewable prices are steadily falling, petro prices are steadily rising, and they are not far from crossing.
For years, there has been a lot of blather concerning these alternatives by the government, which changes little. But when the market speaks, people listen. You can see this in Brazil, where ethanol-powered hybrid cars are now dominating sales. I believe there is a lot of technology now that is finally on the cusp of breaking out.
That being said, nuclear should be a big part of the mix. A new generation of power plants, built in the next ten years, should last us until the 2040s. By then, renewable alternatives should be well established and we will need neither petro or nuclear. The objections to nuclear are nearly all unscientific NIMBY issues and we should do everything to quash them.
As for the government's role, first is the obvious role of permitting. NIMBYism is a serious problem. The second is subsidies. Of course, as libertarians, I presume we generally agree to let the market sort this mess out. Some people earlier pointed out that alternatives would not have a chance without subsidies (for now), but this argument suffers from the obvious flaw that petro receives all sorts of subsidies, too. In particular, their free dumping of all their toxic, green-house-effect causing waste in to the atmosphere is an enormous subsidy. So yes, while a libertarian should support an end to all subsidies, they should also support a very strict concept of "polluter pays". We do not have the latter at the moment.
End subsidies. Force polluters to pay.
Then let the market sort it out.

There is a compromise that I have discovered, after many go arounds on nuclear power on various venues.
How about letting the nuclear industry build a few waste processing reactors at Yucca Mountain. The waste needs to be dealt with anyway.
If they can operate safely, efficiently, and agree to real regulation instead of industry self regulation, then more plants can be considered.
The tradition of contamination and corruption in the past government/industry operation needs to be eliminated before widespread nuclear power buildout occurs. Trust must be restored.
Of course this will mean only a few new plants are built in the next decade. It will be 10 years until they are proven to be safe and safely and economically operated.
Meanwhile that leaves nuclear fission out of the global climate change cure for awhile. Hundreds of new plants would need to be built to have any signifigant effect.
After 10 years of power generation and waste processing, the lessons learned should be applied to new designs and new nuclear plants should then compete without subsidies with other clean power generatinmg technologies on long term cost, including any fuel requirements and future waste disposal costs.
This is a compromise that environmentalists may be able to live with, providing subsidies now in place for coal, nuclear, and fossil fuel power are eliminated.
And a substantial portion of those savings are put into temporary subsidies for wind, solar,and wave power, large scale electrical energy storage, geothermal heat pump heating and cooling, and conversion from internal combustion transportation to battery electric vehicles.
