Nuclear puzzlement

Finally I am starting to hear about something I had been wondering about. If you pour fresh and seawater onto radioactive material, does the water pick up the nuke stuff? If so, all the water that has been poured onto Japan's damaged reactors is draining to somewhere. Some into ground water but most into the ocean.

Don't eat the fish.

Nuclear experts are assuring us that reactors built in the future will be failsafe. I would guess the same claims were made about the ones that went wrong in the past.

Nuclear proponents are, probably quite accurately, giving figures for how many could be killed if a hydro electric dam collapsed. No one can give figures for the numbers that could be killed by a massive nuclear accident.

Nah, shut 'em down.

  2. This earthquake and tsunami breached all the so-called 'ultra safe' measures proving there are NO safe measures or boundaries or crap.
    If it's cheap and easy power then someone's gotta pay the price in the long run...and that muggins would be us.

  3. Before everyone gets over excited, remember access to energy and your standard of living are tied together. And while Hydro, Wind and Solar energy are all great most of the worlds energy comes from "dirty" sources, either nuclear dirt or greenhouse dirt.

    It is currently a matter of pick your poison. According to the press greenhouse issues are going to kill us all, Nuclear at least only kills some of us.

  4. Ann, Thorium does sound interesting and no reason why it can't be used that I know of.

    Ro, Japan's power is very cheap for the consumer. They do make an effort at energy conservation though.

    Indeed Scott.

    True BDT, that is why we have to pay more for our dirty fuel consumption and make the alternatives viable. Australia could easily go solar from a central point in the desert. It is the cost. Don't forget wave power and perhaps appropriate for you, geo thermal.

    People here are really questioning the need for and safety of nuclear power. They're justifibly angry with the government and power companies. I really hope they use their anger to force a change or at the very least, a consideration of alternatives. Yes, fossil-fuel power has it's disadvantages but in a country such as Japan, where earthquakes and tsunami are an almost daily occurance, having nuclear reactors is like playing Russian roulette!
    And not only is it 'don't eat the fish'. It's now don't eat the spinach or drink the milk! V.

  6. Alarmingly V, so much more food has been added to the list. Russian roulette is a good analogy. Game lost, but there are another thirty odd loaded pistols. If Japanese were asked individually twenty ago, did they want nuclear power, they would have said no. But when presented and it is supplying the electricity, what can you do? I heard reactors supply 20 to 30 per cent of Japan's power. Ok, nearly 1/3. Where does the other 2/3 come from?

    Students have told me there was a lot of opposition to the Rokkasho plant 20 years ago but the power company (which is French) had a lot of money to fling about and was able to buy their way in. Having been to Rokkasho, I can see the village received quite a windfall; it's certainly the wealthiest and most modern village I've seen around here!

    I checked electricty production here and apparently the main source is fossil fuel (mostly coal) and thermal energy. Nuclear is second, followed by hydroelectric and finally renewable energy, particularly solar. V.

  8. V, I heard that they choose quiet non prosperous towns when choosing a reactor site. The locals want the employment and stimulus to their local economy.

  9. Yes of course...sadly for the Japanese - few of us will want to buy any foodstuffs from the area for some years... and fair enough - all these purveyors of nuclear power take heed...

  10. Do we buy much in the way of food from Japan MC? I don't really know.

  11. Where does the seaweed used to wrap sushi rolls come from?

  12. Retail is from Japan, but who makes sushi rolls at home. I don't know about wholesale.
