SA govt to hold off on nuclear call

South Australia's government won't decide whether to expand its nuclear industry until the end of the year, despite a royal commission preparing to release tentative findings.

Former governor Kevin Scarce will on Monday reveal his initial response to whether SA should play a bigger role in the mining, enrichment, energy and storage aspects of the nuclear fuel cycle before releasing his final report on May 6.

Premier Jay Weatherill told parliament on Tuesday that the government will consult with the community and the Commonwealth and provide its response before the end of the sitting year in December.
