Less than two years after a government paper called nuclear power an unattractive option, the Prime Minister has become convinced that building nuclear power stations is the only way to secure energy needs and meet obligations to reduce carbon emissions.

In a controversial move, he wants planning procedures to be quickened so that the first stations could be under construction within ten years, far earlier than expected, advisers have told The Times.

After first promising a decision on new stations by the end of this Parliament, then by the end of next year, Mr Blair will face down critics and set up a government review within the next two weeks, asking it to reach conclusions by the early summer.

The stations would be built on existing sites in the hope of reducing public opposition and swifter planning and building procedures. They would involve the latest technology expected to be adopted soon in France and the US.

Margaret Beckett, the Environment Secretary and the Cabinet’s leading opponent of nuclear power, hinted yesterday that even she would back the move.

In an interview with the BBC’s Politics Show, she said that, although there were many problems with nuclear power, “I’ve always accepted we can’t afford to close the door on nuclear.”

But Mr Blair, who has been given private preliminary studies, believes that all the arguments point to nuclear power and has effectively made up his mind, according to authoritative sources. His decision is a remarkable U-turn.

The review, though headed by a senior figure from the Trade and Industry Department, will report to the Prime Minister and Alan Johnson, the Industry Secretary, and contain members from other departments and, crucially, from the Downing Street strategy unit.

Critics will suspect that membership will be chosen to ensure a different conclusion to the last energy White Paper in 2003.

Britain’s 12 nuclear power stations provide 22 per cent of the electricity. Unless they are replaced there will only be three stations left by 2020.

Studies prepared for Mr Blair by Sir David King, his chief scientific adviser, and other advisers have convinced him that renewable forms of energy, such as wind and wave power, cannot fill the gap.

As coal-fired and nuclear stations close they will have to be replaced by gas-fired electricity stations and Britain will soon become a net gas importer.

Mr Blair’s advisers maintain that the debate should not be seen as a competition between nuclear power and “renewables”, which the Government is committed to boosting.

The nuclear option is unlikely to be opposed by the Conservatives. David Willetts, the Shadow Industry Secretary, said at the party conference: “We must make the case for civil nuclear power to tackle the energy crisis with least damage to the environment.”

Gordon Brown is not opposed in principle to nuclear power.

He has already asked Nick Stern, a senior official, to carry out an inquiry into the long-term economics of tackling global warming and another headed by Margaret Beckett, the Environment Secretary, on climate change targets is expected soon.

Labour’s target is to cut present carbon dioxide emissions by 20 per cent below 1990 levels by 2010, but on current projections that it is likely only to reach 14 per cent.

Sir Digby Jones, the Director-General of the CBI, said: “A decision on the future of nuclear power has been allowed to drift too long. Potential investors and the British public both deserve certainty.”

The business group said that public debate must start without delay and be concluded by the end of 2006.

“Nuclear’s position as a reliable, low-carbon energy source is without doubt, but understandable concerns exist about costs and waste,” he said.
