Nuke Tsunami Makes Clean Coal Look Better


I've just published this over at Watts Up With That?

The recent Japanese earthquake and tsunami, which shut down several reactors at the Fukushima Dai-ichi complex in northeastern Japan, followed by a failure of the backup cooling systems that resulted in hydrogen gas explosions and fires, has me re-evaluating my support for nuclear power.

Don’t get me wrong, I still favor nuclear power as part of what Sen. John McCain called an “all of the above” energy policy. We need all the energy we can get to power a vibrant, growing world economy. Our energy future should include nuclear along with clean coal, gas, oil, and renewables, as well as improved energy efficiency and usage. I welcomed the recent resurgence in interest in building more nuclear power plants in the US, a policy supported by both Presidents George W. Bush and Barack Obama. Obama re-iterated that support a day ago.

Nuclear Power and the Environment

The photo shows the nuclear power plant at Crystal River, Florida, coexisting with a dolphin and recreational paddlers on April 11, 2010.

But the key point of this posting is how technology has fundamentally changed our view of the world.

I took the main photo. My friend Bernie Stopper took the closeup inset of the dolphin. The inset photo of me and other paddlers was taken by Barry Schwartz who posted our trip to Spot Adventures. I find it amazing that a group of ordinary people can see and share their adventure with anyone with Internet access in the world on the very evening of the day it happened.

If you click the Spot Adventures link, you see a map and you can zoom in and view our route plotted using GPS coordinates linked to a slide show. If you click on the icon at the lower right, you get a plot of our speed vs distance. As you move your cursor along the speed plot, you see details of location, elapsed time and speed. The most difficult part of the trip for me was the crossing of open, choppy water into the wind along the lower middle of the plot.

le Tour de France and Nuclear Power in France

The high-definition TV coverage of le Tour de France bicycle race on the Versus network is startlingly wonderful. I've been watching it every day. The image to the left shows the routes of the twenty-one stages.

Stage 11, in central France from VATAN to SAINT-FARGEAU ran quite near where I bicycled during a bike-barge trip with a group from The Villages bicycle club back in 2007 . It was great seeing the competitors cycling through two towns our group biked a couple years ago (Pouilly-sur-Loire and Saint-Fargeau).

There seems to be something missing from the TV coverage, however. When we bicycled along the Loire River Valley back in 2007, we often saw the cooling towers of one or two nuclear power plants in the distance.

Indeed, stage 11 of le Tour de France passed near the nuclear power plant at Belleville that I highlighted in this Blog posting.

The lower image shows the many nuclear power plants in France, indicated by stars.

There are many plants quite close to several of le Tour de France stages but I do not remember seeing any of them featured in the TV coverage.

The coverage included aerial images from a helicopter as well as ground-level, and they often described castles and towers and other scenic features. It would be totally appropriate to show a nuclear power plant or two safely generating carbon-free electricity.

Of course, I have not watched every minute of the race and I may have missed an image or two of nuclear power plants. On the other hand it is possible they have purposely ignored the plethora of nuclear power plants which supply some 80% of electric power in France. That is a pity because nuclear power offers a carbon-neutral alternative to fossil fuel powered plants.

Ther are still several stages to go and I hope Versus will take the time to show the audience how France has exploited "green" nuclear power to great advantage.

(Nuclear) Power For the People (of France)

Ira Nearly Gets Arrested in France!
There were no sirens as the gendarme car approached us. Two uniformed guards jumped out and asked if we spoke French. I replied that our Dutch guide spoke French and I called for her to come over and translate.

We had just finished dinner on our barge after a day of bicycling along the Loire River and the canal that parallels it. All day we had observed two large cooling towers in the distance, one belching steam. As the barge docked in Belleville-sur-Loire, I couldn't help notice that the cooling towers were an easy walk. After dinner I suggested we stroll over and see how close we could get! Half a dozen bicyclists and our guide joined me.

Along the way, we took some photos, including the one above that shows the cooling towers on the left and the containment vessel, the cylindrical building on the right, that protects the nuclear reaction.



As we got closer, I left the public road and took a picture of the warning sign, with the containment vessel to the right of it. We then proceeded to the parking lot along the Loire River and observed where the hot effluent from the towers flowed into a small bay and then into the Loire River. That was when the gendarmes approached us.

We were not permitted to be in that area, we were told, nor were we allowed to take photos. We lied that we had not taken any photos and assured the gendarmes we did not plan to take any. I was tempted to ask the gendarmes if I could take a photo of *them*, but managed to hold back! *

I find their warnings about photos kind of ridiculous because anyone in the world can access Google Earth and see the high resolution view of the entire nuclear plant in the photo above. The containment vessels are the two round buildings in the lower right. We walked along the public road on the upper left and were accosted in the parking lot on the upper middle. (The black areas are water and the Loire River itself flows along the upper right.)

France's Committment to Nuclear Power
In any case, we saw nuclear plant cooling towers looming in the distance and belching steam almost everywhere we bicycled in the Loire River area of France. I knew that France had made a major committment to nuclear power for generation of electricity several decades ago and that about 80% of their electricity comes from nuclear.

Some Interesting Facts About Nuclear Power
When I returned home I did some further research and here are some interesting facts:
  • France has some 59 operating nuclear plants while the US has more plants but, since our population and power needs are greater, we get only about 20% of our electricity from nuclear.
  • Environmental activists in the US have stymied further development of nuclear power due to (somewhat justified) concerns about safe disposal of nuclear waste and accidental release of radiation.
  • France and Japan, however, overcame opposition and reduced their dependence on volatile MidEast oil while, at the same time, reducing CO2 emissions.
  • Today, France and Japan have been joined by other countries, including China, India, South Africa, South Korea, and Finland with active nuclear power programs.
  • Ironically, many of the original nuclear reactors in France make use of US-developed technology, while US anti-nuclear activists have inadvertently made us more dependent upon non-renewable carbon-based fuels, increasing human CO2 emissions that may cause substantial global warming. Political pressure seems to be building for a renewal of the growth of nuclear power in the US.
  • Most of the radiation we absorb is from natural background sources and from medical use of radiation. Any mineral that is mined from the earth is likely to contain sources of radiation. That is why a coal-fired power plant emits more radiation into the atmosphere than a nuclear power plant. A person who lives in a brick building is exposed to more radiation than someone who lives in a wooden house because the materials in the brick emit radiation!
  • France has clean air and low cost electricity because of it's adoption of nuclear power generation. (We spent three days in Paris and, although the car and truck traffic was heavy, the air seemed cleaner than New York City or other large US cities. We had unlimited three-day passes for their very well-developed public transit which takes a big load off of auto travel. They have also instituted an automated system where you can obtain a bicycle in one area and return it in an other for a cost of a few dollars a day. We passed a half-dozen automated rental stations within several blocks of our hotel which was near the Arc de Triumph. We saw many people using the distinctive bicycles and we would have tried them out had it not rained on the morning we had set aside for that adventure. The air in the countryside along the Loire River Valley where we bicycled and barged also seemed quite clean.)
  • Electricity costs about 0.03 Euros per KW/hr (about 5 cents US) and has gone down a bit in France over the past decade as our US coal- and oil-powered electricity has gone up. French costs for reprocessing and waste disposal are around 5%
  • France now exports electricity to Italy and England. Prior to their commitment to nuclear power they were a net importer.
  • Disposal of nuclear waste was an issue in France until they came up with a clever *psychologically-based* solution. The radioactive waste products, the people were told, were not being disposed of forever. Rather, they were being stockpiled until research scientists and engineers could come up with a way to make use of them. Each of the nuclear waste "stocking centers" has an associated research laboratory working to find way to make use of the waste products in the future. Given that explanation, several areas in France are competing for the research centers (and associated waste stocking centers) and all the technical jobs that go along with such centers!

Conclusions
I hope readers will Comment on this posting and give their opinions on possible resurgence of large-scale growth of the US nuclear power industry. If we are serious about reducing CO2 emissions (as well as other byproducts of burning carbon-based fuels), nuclear seems to be one of the best proven alternatives.

I accept that storage of nuclear waste and the possibility of disasterous accidents and terrorist attacks are issues that detract from the advantages of nuclear power. However, we need to balance that against the cost in blood and dollars of our dependence upon MidEast oil. What do you think?

*Some years ago, I had a business trip to a NATO meeting at the Royal Air Force Establishment at Farnborough Airport in England. I added a week of bicycling prior to the visit and looked kind of scruffy as I checked in to the hotel where my colleagues and I were going to stay. I hopped on my bicycle and rode the short distance to have a look at the meeting site. Of course, it was behind a fence and guarded gate. I leaned my bike against the fence and started taking photos of the gate and signs and a uniformed guard came running to check me out. I don't think he believed me when I told him I was scheduled for a meeting the following day, but, he was nice enough to take a photo of me and my bicycle in front of the gate!
