Two thirds of a citizens' jury deliberating the Nuclear Fuel Cycle Royal Commission does not want South Australia to store high-level nuclear waste "under any circumstances".

The jury of more than 300 randomly selected people delivered its 50-page report to Premier Jay Weatherill on Sunday evening after deliberating on the issue across three weekends in October and November.

The report outlined concerns with the economics of the proposal, trust, safety and a lack consent, particularly from Aboriginal elders.

"Many jurors believe we don't have the right to make a decision that will have such long term and irreversible consequences for future generations," the report stated.

"Many jurors say 'no' to the state being a dump due to consent, economics, trust and safety and we should cease spending any further public funds.

"The long-term viability of the project is in doubt as it does not consider new technology providing alternatives for the use of the waste; this undermines the economics to the project."

Verdict in but debate is not over

Mr Weatherill said even though the majority of jurors had voted against the proposal, it was not the end of the debate.

"The status quo is no. This jury doesn't believe the present proposal should be taken forward but we need to take into account a whole range of other broad community views," he said.

"This is what we did this for to understand what exactly people were thinking and why they were thinking it, to assist us to make our decision.

"I will now review their report and weigh it up against all of the other data compiled over the past few months."

Juror Alex Tennikoff said he had a lot of concerns with the citizens' jury process and doubted the State Government would accept no for an answer.

"The process was sort of fast and well organised but sort of steered in one direction for a yes vote but then the no vote came through which is what we were all really after," he said.

"They've got the verdict today, they'll go to the office tomorrow and there's plan B that comes out."

Another juror Fuzzy Trojan said he was also happy with the outcome.

"Too many unknowns and too many risks," he said.

Government 'could be paralysed' by distrust

The jury listed a distrust in the Government's ability to deliver major projects as one of its reasons for voting against a nuclear facility in South Australia.

It said the State Government had "a poor track record" in managing large economic issues such as the State Bank of South Australia and its bailout in 1991 under a Labor government, the Motorola affair in 2001 under a Liberal government, and the current ongoing project delivery issues with the new Royal Adelaide Hospital.

Mr Weatherill acknowledged the South Australian community's distrust and said failing to overcome that could paralyse the Government.

"There is no doubt that there is a massive issue of trust in Government, I could sense that and that's why we started the whole citizens' jury process," Mr Weatherill said.

"There is no way forward unless we overcome those issues. It's a much bigger issue than even just the nuclear fuel cycle royal commission.

"This question of trust in Government is fundamental and it will paralyse us from making big decisions unless we can actually grapple with it."

Cabinet will consider the jury's report on Monday with the Government to deliver its own report on the Nuclear Fuel Cycle Royal Commission by the end of the year.
