Scott Morrison tried to be very clear yesterday: Australia's nuclear submarines would not be a Trojan Horse for a military or civilian nuclear program. That didn’t stop his announcement making people excited.

Within hours, the Minerals Council of Australia’s CEO Tania Constable called the move “an incredible opportunity for Australia’s economy”.

“Now that Australia is acquiring nuclear submarines which use small reactors, there is no reason why Australia should not be considering small modular reactors for civilian use,” she said.
