“In terms of exactly how many [reactors] on any plant, we’ll be leaving that to the independent nuclear energy co-ordinating authority, but it is right that we would be wanting multi-unit sites – that’s how you get costs down,” O’Brien told the ABC’s Insiders program.
O’Brien hedged, however, on the amount of nuclear energy he expected to see as a percentage of the overall electricity grid, a key issue for investors when they consider new renewable projects.

“In terms of the broader energy mix, we will be coming out with that in due course,” he said.
The Coalition is preparing to unveil policies for gas-fired power stations and household renewable programs to accompany its nuclear commitment, saying this will allow it to tell voters how much would come from nuclear.
“We will be announcing that at the time that we announce our broader mix,” O’Brien said.
The Resolve Political Monitor found that 43 per cent of voters support the Labor approach to energy, using renewables as well as gas-fired power, while 33 per cent prefer the Coalition proposal for nuclear energy and the remainder are undecided.
“This tells us that while many voters do not reject nuclear out of hand, they can favour an energy pathway that does not include it,” said Resolve director Jim Reed.
Voters strongly prefer renewables to all other forms of energy, with 73 per cent in favour of renewables in general. This climbed to 84 per cent for rooftop solar, the most popular option.
Support was lower for large-scale wind farms on land, at 53 per cent, and wind turbines offshore, at 51 per cent. Only 37 per cent favoured nuclear power when the option was listed alongside renewables and fossil fuels, while only 33 per cent supported coal power.
The survey found 53 per cent of voters backed gas-fired electricity, a key issue when Labor and the Coalition both say this will be needed during times of limited supply from wind and solar. The Greens want a ban on new coal and gas projects as well as a phase-out of existing projects.
Asked to give their reasons for opposing nuclear, voters named safety and the disposal of radioactive waste as key issues, as well as the time required to build the plants.
“It only takes one accident and you’ve got a country contaminated forever,” one respondent said in the online survey.
Asked about the reasons to support nuclear, some respondents said the power plants were safe and economical.
“You need another energy source that supplies baseload power – wind and solar don’t do that,” said one respondent. Another said: “It’s better than burning coal or gas. I can’t believe the greenies are against it.”
In a plan released on Wednesday, the Coalition said it would set up a Nuclear Energy Co-ordinating Authority to select the nuclear companies to build the seven power plants, while also forming Affordable Energy Australia to use a combination of debt and equity to finance the construction.
Dutton and O’Brien have not disclosed any costs for their plan or anything to support their claims the mammoth investment would reduce household energy bills. The Clean Energy Council, which advocates renewable projects, said the Coalition plan would cost $600 billion, while Environment Minister Tanya Plibersek cited CSIRO analysis to say it would cost $387 billion.
Nationals leader David Littleproud did not reject the $387 billion estimate when it was put to him on Sky News on Sunday morning, saying instead the cost would be a “fraction” of the government’s outlay on energy programs.

The Resolve Political Monitor surveyed 1003 eligible voters from Thursday to Sunday, generating results with a margin of error of 3.1 percentage points.
The questions were put to respondents soon after Dutton and his senior colleagues announced seven sites for nuclear power plants and said a Coalition government would fund and own the projects.
