Mr. Barilaro: Nuclear power is “probably the cheapest cost to the average Australian household”.
Facts:
* Nationals Senator Matt Canavan acknowledges that nuclear power is “very expensive”.
* Industry insiders and lobbyists freely acknowledge that nuclear power is suffering from an economic crisis that could prove to be terminal.
* Nuclear power is in decline worldwide and a growing number of countries are phasing out nuclear power including Germany, Switzerland, Spain, Belgium, Taiwan and South Korea.
* Laws banning nuclear power has saved Australia from the huge costs associated with failed and failing reactor projects in Europe and North America, such as the twin-reactor project in South Carolina that was abandoned in 2017 after the expenditure of at least A$13.4 billion, bankrupting Westinghouse. That expensive fiasco could so easily have been replicated in NSW if not for the prudent legal ban.
* There are many other examples of shocking nuclear costs and cost overruns, including:
‒ The cost of the two reactors under construction in the US state of Georgia has doubled and now stands at A$20.4‒22.6 billion per reactor.
‒ The cost of the only reactor under construction in France has nearly quadrupled and now stands at A$20.0 billion. It is 10 years behind schedule.
‒ The cost of the only reactor under construction in Finland has nearly quadrupled and now stands at A$17.7 billion. It is 10 years behind schedule.
‒ The cost of the four reactors under construction in the United Arab Emirates has increased from A$7.5 billion per reactor to A$10‒12 billion per reactor.
‒ The cost of the only two reactors under construction in the UK has increased to A$25.9 billion per reactor. A decade ago, the estimated cost was just A$4 billion. The UK National Audit Office estimates that taxpayer subsidies for the project will amount to A$58 billion.
Mr. Barilaro: “As I write this piece, a further 50 nuclear reactors are being built globally (450 reactors currently operate in 31 counties) including in Finland, France, the UK, China and Canada.”
Facts:
* The number of power reactors under construction has fallen steadily from 68 in 2013 to 49 as of Feb. 2020.
* As noted above, reactors under construction in Finland, France and the UK have been subject to catastrophic cost overruns.
* There has only been one reactor construction start in China in the past three years. The number of reactors under construction in China has fallen from 20 in 2017 to 10 now. Renewables generate twice as much electricity in China as nuclear power.
* No reactors are being built in Canada.
Mr. Barilaro on small modular reactors (SMRs): “Given their size and efficiency, their waste is minimal (new advancements in technology continues to address the waste issue)”.
Facts:
* SMRs would produce more nuclear waste per unit of energy produced compared to large reactors.
* A 2016 European Commission document states: “Due to the loss of economies of scale, the decommissioning and waste management unit costs of SMR will probably be higher than those of a large reactor (some analyses state that between two and three times higher).”
* Mr. Barilaro’s “new advancements” (‘Generation IV’ concepts) have failed spectacularly and have clearly worsened nuclear waste management problems (see p.42-43 of our joint submission to the NSW inquiry).
Mr. Barilaro: “The compact nature of SMRs means they need close to only 5 per cent of the nuclear fuel required for large conventional reactors.”
Fact: As the South Australian Nuclear Fuel Cycle Royal Commission report noted: “SMRs have lower thermal efficiency than large reactors, which generally translates to higher fuel consumption and spent fuel volumes over the life of a reactor.”
Mr. Barilaro: SMRs are “becoming very affordable”.
Facts:
* Every independent economic assessment finds that electricity from SMRs will be more expensive than that from large reactors.
* SMRs will inevitably suffer from diseconomies of scale: a 250 MW SMR will generate 25% as much power as a 1,000 MW reactor but it will require more than 25% of the material inputs and staffing, and a number of other costs including waste management and decommissioning will be proportionally higher.
* A December 2019 report by CSIRO and the Australian Energy Market Operator concluded that wind and solar power, including two to six hours of storage, is two to three times cheaper than power from small reactors per unit of energy produced. Nuclear lobbyists dispute the construction costs that underpin this estimate but, in fact, they are a neat fit with real-world construction costs (as opposed to self-serving industry speculation). Indeed the CSIRO/AEMO estimate is lower than the average cost of small-reactor projects in China, Russia and Argentina.
* SMRs in China, Russia and Argentina are, respectively, 2, 4 and 23 times over-budget. None could be described as “very affordable”.
Mr. Barilaro: SMRs “are now on the horizon”.
Facts:
* A handful of SMRs are under construction (half of them to power fossil fuel mining operations in the Arctic, the South China Sea and elsewhere).
* Private sector investment has been pitiful and the main game is to find governments reckless enough to bet billions of taxpayer dollars on high-risk projects. SMRs under construction are all being built by government agencies.
* The prevailing scepticism is evident in a 2017 Lloyd’s Register report based on the insights of almost 600 professionals and experts from utilities, distributors, operators and equipment manufacturers. They predict that SMRs have a “low likelihood of eventual take-up, and will have a minimal impact when they do arrive”.
* Likewise, a 2014 report produced by Nuclear Energy Insider, drawing on interviews with more than 50 “leading specialists and decision makers”, noted a “pervasive sense of pessimism” regarding SMRs.
Mr. Barilaro: SMRs are “not as water hungry as traditional nuclear power plants, because they use air or sand to cool the core.”
Facts:
* SMRs will likely use as much water per unit of energy produced compared to large reactors ‒ possibly more due to lower thermal efficiencies. Nuclear power, large or small, is incredibly thirsty: a typical large reactor consumes 35‒65 million litres of water per day. Gas cooling creates its own set of problems and inefficiencies, leading to higher costs ‒ that is why a very large majority of reactors are water-cooled.
* Sand to cool a reactor core? Perhaps he means sodium ‒ which has caused a number of fires in fast neutron reactors. Sand has only been used as a desperate measure in the event of major accidents, e.g. Chernobyl. Continue reading
