SA looks to clear nuclear hurdles

South Australia's government will look to remove hurdles preventing further engagement on an expanded nuclear industry.

But Premier Jay Weatherill insists the government hasn't made up its mind whether to back the establishment of a high-level waste dump, as recommended by the state's nuclear royal commission.

He will move on Tuesday to repeal a law prohibiting the use of public money on "encouraging or financing any activity" associated with hosting a nuclear waste storage facility in SA.

Mr Weatherill said he had been advised the law could pose a barrier to a planned community consultation process.

He said the repeal would not pave the way for a nuclear dump by stealth because its establishment would require other legislation to be changed.

"I'm open to deepening our involvement in the nuclear fuel cycle," he told reporters.

"If I didn't think there was a possibility, then we wouldn't have established this process. But we've not yet made a decision as a government."

The royal commission found in its interim report that a high-level dump could generate more than $257 billion in revenue over its 120-year lifespan.

Anti-nuclear campaigners have argued the findings were based on dubious economics and a dump could have massive costs for the state.

The government will await the commission's final report on May 6 before making a decision by year's end.
