EDITORIAL SERIES – PART 4

PART 4 - WHY doesn’t nuclear power make

sense for Australia?


Before we state our summary case against nuclear, we need to understand why nuclear makes no sense here. Some of this is repeated. Nuclear pundits also seem to be adept at misinformation – probably why Dutton is sucked in by it all.

 

1. Nuclear power stations can’t be built anywhere in Australia.

They are banned in every state, and in every territory. Such bans were introduced because of community concerns about the health and environmental risks. Many parliamentary inquiries at a federal and state level – see this Victorian Inquirythis Federal Inquiry, and this South Australian Inquiry for instance – have been held into nuclear energy, and ALL have concluded that it makes no sense in Australia.

2. Nuclear power stations are expensive and take too long to build.

Australia’s independent science information agency, CSIRO, has found that solar and wind are by far the cheapest ways of producing electricity (even when factoring in storage). In contrast, the cost of building and operating nuclear in Australia remains prohibitively high.Analysis conducted by the nuclear industry itself shows nuclear power stations take an average of 9.4 years to build – compared to 1–3 years for a major wind or solar project. Australia needs to replace its ageing coal-fired power stations as quickly as possible to rapidly reduce emissions this decade. As shown in the Australian Energy Market Operator’s Integrated System Plan, by far the cheapest and quickest way to do this is to ramp up renewable energy paired with storage like pumped hydro, and batteries.

3. Nuclear power poses significant community, environmental, health and economic risks.

Radiation from major nuclear disasters, such as Chernobyl in 1986 and Fukushima in 2011, have impacted hundreds of thousands of people and contaminated vast areas that take decades to clean up. Even when a nuclear power station operates as intended, it creates a long-term and prohibitively expensive legacy of site remediation, fuel processing and radioactive waste storage.

4. Nuclear power is not renewable, and it is not safe.

Uranium is a finite resource just like coal, oil and gas. It needs to be mined and, just like mining coal, oil and gas, this carries serious safety concerns, including contaminating the environment with radioactive dust, radon gas, water-borne toxins, and increased levels of background radiation. On the other hand, energy generated from the sun and wind releases no pollutants into the air and is overwhelmingly considered to be safe. 

 

There you have it: nuclear power is expensive, illegal, dangerous and decades away from powering our homes and businesses. It makes no sense. On the other hand, energy from the sun and wind is cheap, abundant, safe and available now. So, let’s get on with building more renewable energy! Don’t let Dutton repeat the massive blunders of Tony Abbott – the cost of his renewables procrastinations has never been calculated to our knowledge but it sure would make fascinating reading!

 

What is a nuclear power station?

Nuclear power stations run on uranium. When a uranium atom is split inside a reactor, heat and radiation is produced. This process is called nuclear fission. The heat produced from this process is used to create steam from water. The steam drives a turbine that powers a generator. The generator creates electricity.

Unlike coal and gas, no greenhouse gas pollution is created in the operation of the nuclear reactor. However, all other steps involved in producing nuclear power – from mining, to construction, decommissioning and waste management – result in greenhouse gas pollution.Small modular reactors are nuclear reactors with a ‘small’ capacity of 300 megawatts or less and ‘modular’ in the way reactor components are produced. Based upon these definitions, no small nuclear reactors have ever been built.

Case Study 1: Hinkley Nuclear Power Station, United Kingdom

When this project was first being promoted, the CEO of EDF, the majority owner of the Hinkley Power Station, predicted that the nuclear power station could be switched on in 2017. It is currently slated to open in 2031, almost a decade and a half late.

Around the same time, the UK Government priced the project at 4 billion UK pounds. It is now expected to cost between £35 and £46 billion pounds. 

These enormous cost overruns have even created tension between the UK and French governments, with the political leaders in both countries disagreeing over who is responsible for covering billions in additional costs.

Case Study 2: NuScale Power, United States of America

Rising project costs forced the only company to have secured regulatory approval in the US for a Small Modular Reactor to cancel its first project. When it launched in 2020, NuScale’s Idaho-based project was expected to cost $3.6 billion US dollars and produce 720 megawatts of electricity. Just three years later, in 2023, the project cost had blown out to $9.3 billion US dollars while capacity had reduced to 496 megawatts. 

At the time the project was cancelled, NuScale had attracted just 20% of the customers it needed to deliver the project.


Finally, there is the cost of power distribution. Proponents of nuclear will tell you they need to build power plants near the existing grid so as to reduce the cost of any additional infrastructure work. They will tell you it is a major component of the cost of your electricity and therefore nuclear plants near existing transmission lines will reduce your costs.

For one thing, this argument holds for renewables as well BUT the big difference is the capital cost of constructing nuclear power plants against building renewable power farms.

Peter Dutton would no doubt prefer to follow the teachings of ‘Nuclear For Climate’ as they suit his proposal on nuclear. But they promote 12 South Korean APR1400 power plants as well as 27 GE BRWX300 SMR’s as their ‘mixed or faster route’ or, 88 BWRX 300 SMR’s for their slower route. Blind Freddy could tell you we’d be at 100% renewables before all these nuke sites were built.
