If you manage to solve all the problems associated with nuclear power, would it then be more expensive than renewable options such as wind?

SOARING oil prices would push Australia more quickly towards the "inevitable" use of nuclear power, Prime Minister John Howard said today.
Mr Howard has also indicated the Government might have to overhaul its 18-month-old energy policy which has a heavy focus on the continuing use of fossil fuels for power generation.
They even produce some radioactive waste, apparently.
Eh? Where's the supporting evidence of this?
The use of either nuclear power or alternate 'green' energies will only become cost effective when we, as consumers, increase our demand for it. Whilst we continue to pull up at a service station and pump petrol into our cars, whilst we are content to have our electricity supplied by fossil fuels, whilst we regard solar power as too expensive to install on our homes - the earth we are supposedly holding in trust (CJH) will continue to deteriorate.
Change is driven by demand in any economic propostition.
AUSTRALIA should not adopt nuclear technology and must focus on other energy sources, Opposition treasury spokesman Wayne Swan said today.
"We are a country with an abundance of energy, we're are optimistic about what can occur with clean coal technologies, we have an abundant supply of gas – I don't see the need for Australia to go down that road."
FOREIGN Minister Alexander Downer has opened a new front in the nuclear debate, saying Australia needed to consider to whether it should enrich uranium.
Prime Minister John Howard has called for a "full-blooded" debate on nuclear power and uranium mining.
NUCLEAR power would cost twice as much as electricity produced from coal, while the world's viable uranium supplies could run out within 24 years, a new report has found.
The report also found that while there was 4.3 million tonnes, or 60 years' worth, of unknown uranium resources, only 1.7 million tonnes, or 24 years' worth, was economically viable to extract, the paper reported.
If nuclear power was cost effective, how come no private energy companies will touch it with a barge pole?
Incidentally coal fired power stations do have a small amount of natural radioactivity in the coal combustion by products but it is a miniscule amount compared to the radioactivity of any nuclear waste.
The only viable way forward is significant investment in energy conservation and renewable energy, with clean coal technologies as an interim measure before the full range of renewables is on stream and as back up until we know whether nuclear fusion is going to be successful

Do you know how much natural radioactivity is released by burning coal? There are vast quatities of waste (gas and solid) that is generated. It wouldn't have to be very concentrated to exceed that produced by nuclear.
Also, there are lots of nuclear reactors around. Maybe a lot of them are privately run. But many companies wouldn't go near it because of the political issues (permission etc), not necessarily the economic issues.
AFAIK Any radioactivity in coal combustion barely registers against background. Certainly nothing like the levels in low level radioactive waste from a nuclear station, let alone intermediate or high level.
The point about any investment in nuclear is that in liberalised electricity markets (and there are plenty out there) then anyone can build a plant and sell to the grid. No company will come to the marketpalce with a nuclear new build unless someone (i.e. the government) will underwrite the costs of waste management and decomissioning. If it was such a good thing financially then people would be seeking planning permission now but apart from heavily subsidised plants no one is interested in building them.

If you are considering the impact of the entire cycle, then no process which requires mining and waste processing or management will be ever be truly cost effective ... traditionally, environmental costs have been deferred to later generations ... and this is equally true of wood, coal, oil and gas ...

There aren't any truly liberalised electricity markets. If the people kick up enough of a fuss they can block any power plant - even wind farms.

Considering huge subsidies (both direct and indirect) for the nuclear power industry, it is quite difficult to come up with true costs. Who will pay for long-term waste disposal, even if it is possible? How can we put a price done on the damage caused by Chernobyl?
I do not think nuclear power can ever be truly cost-efficient, but I image the industry and its supporters can come up with some figures to show that it could be. The situation is similar to that of petroleum; I saw an article that says gasoline would have to sell for $20 US per gallon to truly cover all the costs involved--including not only extraction, production, and distribution, but also the cost of wars (which themselves have many hidden costs) and environmental clean-up.
The odds against a major nuclear accident are slim, yet the cost involved in preventing one is great. If there were a major accident of the dimensions of Chernobyl, the cost would be much higher.
