Why is Dr Adrian Paterson, the former chief executive of the Australian Nuclear ­Science and Technology Organisation (ANSTO), which operates the Lucas Heights reactor in Sydney being ignored.

Dr Paterson has written to Prime Minister Anthony Albanese demanding urgent action to keep the nation’s lights on.

Paterson asks: “Why are we as a modern democracy banning nuclear at the federal and state level when low-carbon nuclear provides the cheapest consumer costs? Nuclear would transform an electricity grid which is getting … less reliable plus getting very, very expensive.

“Your electricity plan, for a massive expansion of the grid with wind and solar sources is deeply flawed and expensive. It will fail to deliver quality, 24-hour electricity,” Dr Paterson warned.

Dr Paterson said nuclear energy production stands apart from wind and solar because it doesn’t require a “massive expansion” of the grid – the cost of which would easily fund the first nuclear power plants.

Regarding a CSIRO report that claims nuclear will be too expensive, Paterson says: “CSIRO has no expertise in the cost of generation.

“What they do is take publicly available figures of the construction costs of nuclear power plants – usually in countries that have got regulatory environments that are kind of designed to stop nuclear – and convert them into a generation cost using an algorithm which is provided to them by a private sector firm that is not an expert in the nuclear industry,” he says.

“I’ve engaged the CSIRO for several years both directly and also through the press to say that we can work together to sort this out and they have no inclination to do it. People don’t know that to build all of the planned solar panels and wind turbines we’re going to have to double the size of the grid, which is 40 percent of electricity bills.

“The eastern grid in Australia is the most complex machine in the southern hemisphere. The policy of this government is to make it twice as big as it is and twice as complex if you have to integrate intermittent sources into it.

“How do people believe that we can create a grid that’s double the size with lower energy density and still have the current quality of life?

“The current policy is based on a failure to get proper engineers in the room. Engineers are being banned from giving talks as we speak,” Paterson says.

Commenting on his letter to the PM, Dr Paterson said Australians should be given a choice in how their electricity is generated.

“We shouldn’t be making decisions based on the personal preference of Anthony Albanese. This ‘Captain’s Pick’ mindset is stuck in the 80s when he was an antinuclear campaigner at Sydney University.

“It’s time Australia had the option to join the rest of the world, who are already using nuclear to stabilise the grid and power their economies.

“Why should Australia miss out on cheap, clean fuel? Why should Australians pay more to keep the lights on at home? Why not keep businesses doors open and unemployment low?”

Dr Paterson served as chief executive of ANSTO for 12 years, has degrees in chemistry and engineering, sits on the board of HB11 Energy, a company developing laser hydrogen fusion technology, and is now the principal and founder of energy advisory Siyeva Consulting.
