  1. He said CT scan on Radioactive Concrete From Fukushima Found In New Construction · · Score: 1

    He said CT scan not a simple X-ray, much more radiation.

  2. Yes you did on Radioactive Concrete From Fukushima Found In New Construction · · Score: 1

    Sorry for misreading.

  3. RTFA on Radioactive Concrete From Fukushima Found In New Construction · · Score: 4, Informative

    The limit is 1 millisievert PER YEAR. The dose was accumulated in three months so the rate is 6.4 millisievert PER YEAR, well above the limit.

  4. Eating doughnuts in the control room on Radioactive Concrete From Fukushima Found In New Construction · · Score: 1

    can be boring without slashdot. If they are not here, they are probably napping....

  5. Wrong on Radioactive Concrete From Fukushima Found In New Construction · · Score: 1

    The chart says 40 microsieverts for one chest X-ray. TFA says 1.6 millisieverts in three months. So, the rate is 640 chest X-rays per year, not one. That is much higher than the NRC's public exposure limit of 100 mrem/year (1 millisieverts/year).

  6. 640 chest x-rays / year on Radioactive Concrete From Fukushima Found In New Construction · · Score: 1

    Right.

  7. 64 chest x-rays / year on Radioactive Concrete From Fukushima Found In New Construction · · Score: 2

    And that dose was in only three months, so it is 64 chest X-rays per year.

  8. Why Fukushima? on The Doomsday Clock Is Moved Closer To Midnight · · Score: 1

    I was curious about this so I listened to the press conference. They are saying that Fukushima shows that the global nuclear power industry is vulnerable to the worst run nuclear plants. Basically they are afraid that Fukushima will slow the growth of nuclear power which they (mistakenly) think would help with global warming. http://www.rmi.org/Knowledge-Center%2FLibrary%2FE09-01_NuclearPowerClimateFixOrFolly

  9. MAD works? on The Doomsday Clock Is Moved Closer To Midnight · · Score: 1

    Careening from crisis to crisis does not seem like something that works. It has not crashed yet, but it will. Disarmament is what works.

  10. Used solar on Kenya Seeks Nuclear Power Infrastructure · · Score: 1

    One thing that we can expect is that a portion of solar power installed in the west will need to be removed when a building is refurbished or reroofed. When reinstalled, new panels will be used to match the renewed condition of the building (and the lower present cost of panels). That makes an aftermarket in used panels which may be very attractive in Africa.

  11. Many accidents at nukes on Where Were the Robots In Fukushima Crisis? · · Score: 1

    You can only say that about a plant that was closed without ever having an accident. Maine Yankee, for example, had three accidents before it was closed because it was a major accident waiting to happen. Even Humboldt Bay, which barely operated at all because designers ignored seismic data, managed to lose nuclear fuel. Relying on defense-in-depth rather than intrinsically safe operations means the defenses do get used.

  12. Re:75 years of uranium on Report Condemns Japan's Response To Nuclear Accident · · Score: 1

    You can go and look it up. Silly to claim I'm lying when the info is right there.

  13. Re:75 years of uranium on Report Condemns Japan's Response To Nuclear Accident · · Score: 1

    You do understand that the experiment was shut down without even using thorium as a fuel right? Wishful thinking seems to be your main thought pattern.

  14. Re:75 years of uranium on Report Condemns Japan's Response To Nuclear Accident · · Score: 1

    They didn't do anything. The experiment ended because it failed. Proposed post-failure bandages are just chitter-chatter.

  15. Re:75 years of uranium on Report Condemns Japan's Response To Nuclear Accident · · Score: 1

    "Post-operation examination of pieces of a control-rod thimble, heat-exchanger tubes, and pump bowl parts revealed the ubiquity of the cracking and emphasized its importance to the MSR concept. The crack growth was rapid enough to become a problem over the planned thirty-year life of a follow-on thorium breeder reactor."

    "The ensuing decontamination and decommissioning project was called "the most technically challenging" activity assigned to Bechtel Jacobs under its environmental management contract with the U.S. Department of Energy's Oak Ridge Operations organization. In 2003, the MSRE cleanup project was estimated at about $130 million...."

  16. Re:75 years of uranium on Report Condemns Japan's Response To Nuclear Accident · · Score: 1

    Those reactors don't work well and even the unused fuel is difficult to clean up so we'll see how that goes.

  17. 75 years of uranium on Report Condemns Japan's Response To Nuclear Accident · · Score: 1

    With about 75 years of uranium left at the current consumption rate, bringing on China gets us to less than 40 years. So, a plant built now will run out of fuel before it is payed off. The sooner China comes on line, to sooner we'll be done with nuclear power.

  18. Re:Obligatory from The Onion on TV Ownership Declines For Second Time Since 1970 · · Score: 1

    I only use one TV but I bought a digital early. It broke after a hurricane and I decided to buy used because I prefer the CRT to the plasma or LED. It was very hard to find a used TV. I finally went with a good SONY HDTV that lacked a digital tuner combined with a tuner box with HD output that had been a demo given to an FCC guy. That took dedicated searching. But you can get TVs like the ones you replaced for free. Most tuner boxes only put out standard resolution so there is no improvement going to digital with those TVs and the subsidized tuner boxes.

    So, I think we are seeing a very tight used market for HDTV and a very pricy latest tech driven new market. Little wonder that ownership is down. A lot of false advertizing that you have to have cable or satellite to get HD is probably souring the market as well.

    Actually, repeating denialist memes is arrogant deceit. You didn't read the paper carefully.

    If you read this paper carefully, you'll see that your proposed action would reverse most of the warming. http://www.pnas.org/content/early/2009/01/28/0812721106.abstract

    Keeping people alive and available to clean up the atmosphere would reverse all of it. We control the climate knob. Got to be around to do it though.

    Indeed we do control it. We are making it warmer.

    What is new is attribution of severe weather events to human activity. http://www.columbia.edu/~jeh1/mailings/2011/20111110_NewClimateDice.pdf

    When heatwave deaths are your fault, it is time to take corrective action.

    Also, you are incorrect that trying to keep things steady is the way to extinction. This is some Frank Herbert meme but it has no basis. Beavers keep pond water levels constant and do just fine.
