    currently we use 0.7% of the uranium mined. The rest is put into "storage." For the last 30 years the number of nuclear power plants has remained constant and thus we have 30 years of 0.7% usage. At current usage the other 99.3% would get us 4,200 years. Thats just the uranium we already have stored above around at the nuclear power plants. Not including reserves in the ground. If you include the reserves in the ground we are talking about in the 10's of thousands of years.
    I would say thats quite a wrong statement by a massive magnitude.

    However, as also said earlier. We got plenty of uranium in the ground. But its just getting more and more expensive to digg out. That means prices are rising fast and nuclear power equally to increase cost. Also the supply of cheap fuel from old russian nukes and such is close to an end.

    In dec. 2001 the price on NA UF6 was about 30$. In dec. 2006 it was 200$. And atm its artificially low due to recycle of nuclear weapons.

    Uranium mines are getting empty, new needs to be open. The estimate is we can make 300 times more, but at 10x the cost.

    In 2005...

    • Supply from mines was 102.5 million pounds
    • Demand was 171 million pounds
    • The gap was 68.5 million pounds.
    Must be alot of..."storage".

    -self-sustaining (billions in subsidies are not required)
    -environmentally safe (producing solar panels requires the manufacture of many toxic chemicals...same for the plastics wind turbines are constructed from)
    Holy crap...
    Zero emissions. Same as everything else. Tho you do know cooling towers?
    Unlimited..yes...but at a very very high price if demand keep going up.
    Minimal land usage? No..you want large safety zones. You dont want to be a neighbour to one.
    Safe? Highly radioactive materials aint safe. Just because it cant do a melt down doesnt mean it can expose alot of radiation and radioactive materials to the surroundings.
    Self-sustaining? No. There is large goverment funding behind nuclear plants. Else they would build coal due to cheaper prices.
    Environmentally safe. See safe, plus the waste disposal is...safe? I think not. And for solar panels and windmills etc you can recycle. With nuclear waste you need 40000 or so year storage somewhere. A nice present to future generations.

    I could say alot better things about nuclear plants. But it would be none of the above if compared to renewable energy sources.
