Coalition plans to build seven nuclear power plants are "economic insanity", the treasurer says, ahead of a speech by the opposition leader unveiling details behind the policy.
The federal opposition has outlined plans to build seven nuclear reactors across five states, should they win the next election, with the first to be built by 2035 to 2037 at the earliest.
The proposed reactors would be built in areas with existing coal-fired power stations, including the Hunter Valley and Lithgow in NSW, Victoria's Latrobe Valley, Collie in Western Australia and Port Augusta in South Australia.
