Cost update blasts nuclear out of energy mix

Canberra Times, By Marion Rae, December 21 2023

A surge in the cost of small nuclear reactors has forced the national science agency to change its calculations for Australia.

The latest modelling of all energy sources, released by CSIRO on Thursday, includes data from a recently scrapped project in the United States that was showcasing nuclear small modular reactors (SMRs) as a way to fight climate change.

The draft GenCost 2023-24 report, out for consultation over summer, shows that while inflation pressures are easing there has been a recalculation on SMRs that puts them out of reach.

Real data on a high-profile six-reactor power plant in the United States has confirmed that the contentious technology costs more than any energy consumer wants to pay.

Project costs for the Utah project were estimated at $18,200 per kilowatt, but the company has since disclosed a whopping capital cost of $31,100/kW, prompting its cancellation in November.

In contrast, under existing policies the cost of new offshore wind in Australia in 2023 would be $5545/kW (fixed) and $6856/kW (floating), while rooftop solar panels are calculated at a modest $1505/kW………………………………………………………………………………………………………………..

A small but vocal group of industry backers have been calling for nuclear SMRs for some years, citing the emerging low-emission technology as being suitable for Australia’s vast and geologically stable landmass.

The coalition recently pledged to reopen the nuclear debate in Australia, where laws ban any research or use of nuclear energy despite the country having the world’s largest uranium reserves.

Regulators estimate it would be around 15 years to first production from a decision to build nuclear SMR in Australia, given the scale of legislative change required.

But even if a decision to pursue a nuclear SMR project in Australia were taken today, with political backing for new laws, it is “very unlikely” a project would be up and running as quickly as 2038, CSIRO said.

Further, CSIRO warned nuclear electricity costs put forward by proponents may be for technology that is not appropriate for Australia, or calculated from Russian and Chinese government-backed projects that don’t operate commercially.  https://www.canberratimes.com.au/story/8467236/cost-update-blasts-nuclear-out-of-energy-mix/
