The federal government has reaffirmed its support for South Australia's royal commission into nuclear energy but is yet to commit to any change in regulatory policy.

Industry Minister Ian Macfarlane says Australia needs an informed debate about nuclear energy industry and the royal commission is a good start.

He says any increased involvement must come with a robust, stable and predictable regulatory system to give the community confidence that risks can be managed effectively.

"Some of the activities being investigated by the royal commission would require change in commonwealth legislation and the establishment of supporting regularly and policy frameworks," the minister told a resources conference in Port Augusta on Wednesday.

"While the government's submission does not advocate any change in commonwealth policy, it has committed to seriously consider the royal commission's report in 2016."
