South Australia should build a used-nuclear fuel and intermediate-level waste storage facility, the final report of a state royal commission has recommended.

The report by commissioner Kevin Scarce was handed to the SA Government at the end of last week and made 12 recommendations.

They include pursuing a waste dump, simplifying mining approvals processes and seeking a relaxation of federal restrictions on nuclear power generation in Australia.

Premier Jay Weatherill said the State Government planned to consult the community widely about setting up any dump and urged the public to "keep an open mind".

The royal commission said an independent agency should be established to oversee further investigations and a way forward would hinge on achieving bipartisan support.

Mr Weatherill said community engagement would be pivotal in the debate.

He said the Government would develop a response to the final report and present it to the South Australian Parliament by the end of the year.

"The royal commission's final report provides a substantial evidence base for the South Australian community to embark on this discussion," he told a media conference.

"I want to encourage all South Australians first to keep an open mind, secondly to appraise themselves of the facts that are contained within the report — and thirdly, for as many of them as possible, to participate in this most important debate about SA's future."

SA Opposition Leader Steven Marshall welcomed release of the final report.

"The royal commissioner has laid the groundwork for a substantive community debate regarding the recommendations contained in the report," he said.

"I look forward to the people of South Australia having their say about the future of the nuclear fuel cycle in our state."

Conservation SA chief executive Craig Wilkins said the final report was a disappointment.

"For all the lofty spin and the claims of a fistful of dollars, becoming the world's rubbish dump is hardly a source of state pride," he said.

"All big decisions have consequences but what makes this one super important is that it is irreversible — it's a forever decision. We can't send this stuff back if we change our minds."

Mr Weatherill also used the media conference to reveal the state budget would be delayed, due to the federal election, until July 7.
