The UK government has said it will not subsidies new nuclear power stations. However this seems to refer to the most overt form of subsidies and not to "hidden " subsidies.
Nuclear power stations are so dangerous that no insurance company will undertake to pay the total costs of a disaster or a terrorist attack. So in order to get them built the government has to limit liability. This is a subsidy.
The cost of decommissioning will be an enormous sum and the final total is unknown.
Any limitation to liability for decommissioning costs will be a subsidy. If the industry does not pay the total costs of disposing of nuclear waste and ensuring it is safe for thousand of years then this is a subsidy. The industry does not pay the total costs of all research into nuclear energy .This is a subsidy.
Nuclear power stations use the same technology as that required to manufacture nuclear weapons
Any country which purifies uranium for use in nuclear power stations can also use its purification plant to manufacture weapons grade fissile material.
Already nuclear power development has been used repeatedly as a cover for developing nuclear weapons. Of the 10 nations which have developed nuclear weapons "six did so with political cover and/or technical support from their supposedly peaceful nuclear program -- India, Pakistan, Israel, South Africa, North Korea and France' 3 .
The resulting nuclear waste will be dangerous for thousands for years
Since nuclear waste will be dangerous for thousands of years 4 we are dumping our energy problems on future generations instead of using the benign methods of creating energy which are available to us.
The currently favoured "solution' of burying the waste in bedrock and sealing off access for ever is desperate and irresponsible.
The plants and waste deposit storage are vulnerable to terrorist attack
Because of their destructive potential nuclear power stations are a major target for terrorists. The 9/11 atrocity would be tiny by comparison. If a large plane were flown into a nuclear power station the disaster would be immeasurably worse than Chernobyl.
John Large, an international expert on nuclear power, has said that if a plane was flown into the nuclear waste storage tanks at Sellafield the whole of the English Midlands could be catastrophically contaminated.
