The uranium industry says Britain's expansion of nuclear power will bolster Australia's role as a supplier.

The British government has invited companies to construct new nuclear power stations to meet its climate-change goals and will not set a limit on how many are built.

The move is expected to add momentum to a worldwide revival in nuclear energy.

The Australian Uranium Association said the industry would ultimately benefit from such an expansion.

"The reasons for the British government's decision to renew its nuclear power capacity are also the reasons Australia needs to expand its uranium industry and exports," executive director Michael Angwin said.

"With nearly 40 per cent of the world's uranium, expansion of Australia's exports can be a significant part of our contribution to the management of the world's greenhouse challenge," Mr Angwin said.

"Through an expansion of its exports, Australia also has the potential to make a major contribution to security in global energy supply."

Australia currently supplies about 400 tonnes of uranium a year to Britain, making up just four per cent of its exports.

Mr Angwin said Britain had effectively committed itself to nuclear power for the next 70 years and other countries would follow its lead.

"Every decision like Britain's strengthens the case for the expansion of Australian uranium industry and repudiates the case that some still make against expansion."

The South Australian government on Friday also gave approval for the nation's fourth uranium mine to begin production at Uranium One's Honeymoon mine in the state's north.

"Our industry remains optimistic that, over time, it will be able to expand operations to help meet the world's clean energy needs and, at the same time, help offset the cost of structural adjustment that may accompany Australia's own efforts to deal with its greenhouse emissions," Mr Angwin said.

The association represents uranium explorers, miners and exporters.
