Uranium explorers say the public could warm to the idea of nuclear power once the costs associated with carbon trading are released.

A report on the cost of climate change from economist Professor Ross Garnaut is expected to be made public today.

West Australian uranium explorers are hoping Australians will change their attitude to nuclear energy when the cost of an emissions trading scheme hits home.

The physicist and businessman who chaired the Howard Government's nuclear task force, Ziggy Switkowski, says nuclear power would reduce emissions.

"If fossil fuels are progressively seen to be unacceptable because of their emissions then the only alternative to fossil fuel for large scale production of electricity remains nuclear power," he said.

Mr Switkowski says other countries have made the most of reasonably priced nuclear power.

"I would assume that the recent trip that Prime Minister Rudd has made along with Minister Carr around the world would have exposed him to the changing opinions right around the world," he said.

"Countries are now supporting and in fact accelerating their own plans to introduce more nuclear power into their mix."
