    Nuclear power stations

    Nothing to do with bikes whatever, but I've just been looking at a French physics website where they have posted an amazing time sequence of the spread of radioactivity from Chernobyl: http://www.irsn.org/va/05_int/05_inf...hernobyl.shtm#. Virtually no-one in the Northern Hemisphere escaped. I've always been profoundly glad to be living Down Under but it was announced that the Aussies are looking at up to 25 nuclear stations on the eastern seaboard. And which way do the winds blow???

    what the hell do they need nucular power stations for?
    I'm not a complete idiot... some pieces are missing

    To generate enough power to meet demand. Australia may not have the natural resources that we do in order to generate power (Geothermal, Hydro, gas).

    well they don't seam to have any water..... and solar power seams tooooo clean


    what a ride so far!!!!

    ok... so for power... fair enough reason I guess...

    And just so I understand... they are only a problem when they blow up right?

    Melt down, rather than blow up. But the chances of that happening are remote. The safety record of nuclear power stations is impressive, Three Mile Island and Chernobyl aside.

    The most significant issue for nuclear power stations is all of the hot water they produce. Ideally they should be located in the middle of large population centres so that this boiling water can be reticulated for homes and for heating. Otherwise vast cooling lakes and canals are required to get the temperatures low enough before the water can be recycled into lakes or river systems.

    Not every country in the world is like New Zealand, where most of our electricity is generated from renewable sources, like hydro, geothermal and (gahh) wind. Most of the world gets its electricity from burning coal. Australia produces 75% of its electricity from coal, other countries are totally dependent. Our current fixation on "climate change" and the emissions from fossil fuels mean that energy planners are having to look elsewhere. Until somebody figures out how to cheaply manufacture hydrogen for fuel cells or cracks the dark art of cold fusion, all of the alternative ways of producing electricity are known. And nuclear is a credible option that should not be discarded or lampooned by the tree-hugging, SUV-driving soccer mums amongst us.

    It is very very rare that that happens. The ones that they are talking about making would use minimal amounts of uranuim and would be nowhere near the same size as ones in the US for example.
    It causes less damaging effects to the enviroment etc (unless they blow up) than generation by means of coal/oil/gas.

    We discuss it a lot at work.
    Our main form of generation is hydro

    Very very very well put Hitcher!!!!

    Umm... and the safe disposal of waste for a few aeons.

    Hopefully, the Aussies will bury it in their own backyard and not ditch it on some third world country that needs the cash. Might be a while anyway, the environmentalists are successfully stalling a pulpmill from being built in Tassie and they could probably have a field day with nukes.

    Meh, modern nuclear power stations are inherently fail-safe, the kind of reactor that the Australians would use has multiple negative feedback mechanisms as part of the design. These reactors are far removed from anything related to the inherently un-safe Chernobyl type.

    The danger, especially in this age, is that of deliberate attack, something not to be taken lightly.

    We didn't escape either. But coal is worse. We burn 6000 million tonnes of coal each year. Coal is between 1 and 10 ppm Uranium. Ergo we release at least 6000 tonnes of uranium into the atmosphere each year normally. Which is about 12 tonnes of U235. Which is about 2.5x what Chernobyl is missing from it's reactors. And that's how much we dump each year, with an exponential growth pattern. Personally I'd rather live closer to a nuclear reactor than a coal one.

    I don't care how it's generated, so long as I can turn a light on at night.

    About time we set up Tesla's wireless DC power transmission system I reckon.


    If a man is alone in the woods and there isn't a woke Hollywood around to call him racist, is he still white?

    Fast breeder and pebble bed reactors would be the go.
