We’re getting closer to a sensible debate on nuclear power

Judith Sloan


Australia’s experience with nuclear power can best be summed up by the phrase “missed it by that much”. We’ve come close to establishing a nuclear power industry but events conspired against it.
So can we create the conditions that might lead to the construction of nuclear power plants? After all, we’re blessed with ample uranium and nuclear-powered electricity has the advantages of being both reliable (24/7) and emissions-free.

Long-serving South Australia premier Tom Playford was a fan of nuclear energy. Indeed, the South Australian government owned a uranium mine at Radium Hill that operated through to 1961. He wanted a nuclear power plant constructed in his state, but a technological jump enabled the very poor quality brown coal at Leigh Creek to be the source of fuel for a power plant that was built at Port Augusta.

In the 1960s, plans were developed to build Australia’s first nuclear plant at Jervis Bay. Development was shelved in 1969, mainly weighed down by the lack of cost competitiveness of the plant relative to coal-fired generation.

In the late 2000s, Martin Ferguson, as the Gillard government resources minister, became enthusiastic about nuclear power for Australia. He did an in-depth investigation, including travelling overseas to consult with leaders in the field.

Then in March 2011 the Fukushima disaster occurred. The Daiichi nuclear power plant was inundated by a tsunami, the cooling systems of three of the reactors failed and a series of explosions occurred. There were no immediate radiation-related fatalities but the negative impact on the public’s acceptance of nuclear power was substantial.

The Japanese government opted to shut all the country’s nuclear power plants and the German government similarly made the decision to wind down its nuclear plants. In this context, it’s interesting to detail a recent National Bureau of Economic Research study on the impact of the fallout from the Japanese accident. Nuclear power was replaced by fossil fuels and electricity prices rose quickly — by almost a third. It is estimated that there were 1300 cold-weather related deaths in the period 2011 to 2014.

The authors conclude the “increase in mortality from higher electricity prices outnumbers the mortality from the accident itself, suggesting the decision to cease nuclear production has contributed to more deaths than the accident”.

Good ideas never die. The environment and energy committee of the House of Representatives is running an inquiry, chaired by Ted O’Brien, into the prerequisites for nuclear energy in Australia. This inquiry has called into question the credibility of the CSIRO. While many scientists laud the advantages of nuclear energy in terms of generating reliable, zero-emissions electricity, the presumed high cost of plant construction is often mentioned as a major impediment to its rollout.

The CSIRO puts a figure of $16,000 a kilowatt for the construction of small nuclear modular reactors. It turns out this figure is in Canadian dollars and is cited in a report produced by one group but the ultimate source of the figure remains unclear. This much is actually accepted by the CSIRO.

When it comes to whether this cost might have fallen over time — there is a much lower cost estimate ($7000) from another source — the CSIRO is standing by $16,000.

The CSIRO is nigh on useless when it comes to this issue. As Trent Zimmerman, a member of the committee, stated: “It sounds remarkably vague … basically, you’re relying on a third party, who’s relying on a website, and you haven’t been able to fact-check that information yourself.”

The big roadblock in Australia is the Environment Protection and Biodiversity Conservation Act 1999. The good news is that the amendment required is very simple — the removal of “a nuclear power plant” in section 140A (1)(b).

It is possible this could pass both houses of parliament, even though the Greens are likely to oppose it notwithstanding that nuclear energy is so environmentally friendly.

There are some exciting technological developments in nuclear energy. You once needed very large plants, but smaller-scale options are now available. Nor do they necessarily require large volumes of water.

The third episode of Inside Bill’s Brain available on Netflix covers many of the issues and describes Bill Gates’s start-up, TerraPower. It’s worth watching.

Gates makes the point that energy is core to our modern lifestyles — it is his starting point — but he is concerned about energy that emits high volumes of carbon dioxide and acknowledges the public’s reservations about nuclear. His team of extremely well-qualified nuclear physicists and engineers aim to create fail-safe nuclear plants no longer dependent on power and human intervention in the event of an accident.

The TerraPower plants will use depleted nuclear waste, meaning that it can’t be used for weapons’ production. There is enough nuclear waste in the US to power the nation for 125 years. And instead of having cooling towers, the plants use molten metal to prevent explosions in the event of overheating. The reactors automatically shut down and the heat is passively removed.

In fact, a prototype plant was ready to be rolled out in China when the China-US trade war erupted and the US government withdrew its consent.

Our government could approach TerraPower to see whether it is interested in constructing a plant here.

According to the Australian Skeptic magazine, the risk of dying from cancer post Fukashima, was around the same as moving to Melbourne or Sydney. People died in hospitals unnecessarily after being abandoned. And there have been some very promising developments in the treatment of nuclear waste.


Coal is already killing thousands, if not millions of people a year but because it's not spectacular, it doesn't get any coverage.


I still hope solar, particularly extra-terrestrial solar, gets traction (https://www.smh.com.au/world/north-...r-solar-power-with-china-20190920-p52ta4.html) but if it was a choice between coal and nuclear, I'd be going for nuclear every time.

............People fail to realise that nuclear is the only proven technology that has decarbonised the economies of entire countries, including France and Sweden. We can pair renewables with nuclear energy and start to meet our energy targets. But it will take a change in mentality and new investment in nuclear energy.

So this is why I’m now on a mission to help people discover and rediscover nuclear as the clean technology solution to decarbonise our electricity systems and solve the climate crisis. We need to extend the life of existing plants rather than close them prematurely. We need to invest in new modern technologies including small modular reactors, which can be deployed in off-grid settings such as remote communities and mining sites. And we need to use nuclear alongside renewables to power the grid.

We must act before it's too late. And we can't afford to be distracted from real, practical solutions by a completely impossible d
ream of 100% renewable energy. We don't want to look back on this time and realise we made the wrong decisions. The time for nuclear is now."

It's interesting that pairing renewables with nuclear in France almost doubled CO2 emissions (40 to 70g CO2 per kwh).

Personally I see the only solution to CO2 is SMRs like TerraPower.
1) safe
2) use spent fuel rods and nuclear waste as fuel
3) RENEWABLE as there is over 5 billion years of fuel............longer than the sun
4) $0.04 per kwh according to Rolls Royce

It will happen, the question is just on what scale it is rolled out.




US were in the lead until Trumps trade war with China, denying TerraPower a market with scale
Russia now appears to be in the lead but I'm hearing there is a little spin doctor at work
China in my opinion will take the lead
Rolls Royce appears to be the leader in the West
Bill Gates would have already delivered if not for Trump. Instead, China can take the technology and take the lead from the US.
 
Just for interest, Australia's only publicly-known reactor site (dunno how many might be floating around undocumented!) at Lucas Heights in Sydney has had two reactors on the site. A High Flux heavy water reactor which came online in the 1950s and was decommissioned in 2007 and the new 'Open Pool' light water reactor which has been used from 2007 onwards.

The site probably needs a little TLC as this article from 2018 shows;


A 1950s-era nuclear medicine lab in south-west Sydney should be replaced after a worker was exposed to radioactive material, an independent expert review has recommended.
Key points:
  • A worker was exposed to radioactive material in 2017 and now faces a higher risk of cancer, the review said
  • ANSTO will produce an "action plan" in 60 days in response to 85 recommendations
  • The review noted that a fifth of ANSTO staff reported experiencing workplace bullying

The review, published this morning, said the Lucas Heights facility failed modern nuclear safety standards and had a culture of "make-do and mend".

An incident at the facility — known as building 23 — occurred in August last year, and was deemed the most serious in the world in 2017. It was the only incident at the time that was classified as a Level 3 event in the International Nuclear Event Scale...

Still, reactor tech is generally only getting safer. I think Australia should move forward with nuclear power, maybe even our own nuclear deterrent. I hate the idea of Australia being this pathetic cringing thing clinging to the skirts of whatever superpower currently holds sway in the world (yesterday it was the U.K, today the U.S, maybe China tomorrow?). A defensive nuclear deterrent will help wean us off relying on the military backup of others.

While I long for world peace I don't think the 'nuclear genie' is EVER going back into its bottle. We should recognise this fact.

I don't know if it's been verified by many outside sources, but China reckons it's kicking arse in the fusion field.

Chinese nuclear scientists have reached an important milestone in the global quest to harness energy from nuclear fusion, a process that occurs naturally in the sun.

The team of scientists from China's Institute of Plasma Physics announced this week that plasma in their Experimental Advanced Superconducting Tokamak (EAST) — dubbed the "artificial sun" — reached a whopping 100 million degrees Celsius, temperature required to maintain a fusion reaction that produces more power than it takes to run.

To put that in perspective, the temperature at the core of the sun is said to be about 15 million degrees Celsius, making the plasma in China's "artificial sun" more than six times hotter than the original...

...He said that the achievement by EAST will be important to the development of the next major experiment in global nuclear fusion science: the International Thermonuclear Experimental Reactor (ITER).

Currently being built in southern France with collaboration from 35 nations including China, ITER is set to be the first experimental fusion device to produce net energy, producing 10 times more energy than the power required to run it, according to the project website.

While ITER is only an experimental facility and will not harness the fusion energy to create electricity, if successful it could pave the way for future nuclear fusion plants.

As EAST has a similar design to ITER but on a far smaller scale, it is likely to be an important testing device during the development of ITER, according to China's Institute of Plasma Physics.

ITER is expected to be ready to create its first plasma and begin operations in 2025.
 

nuclear fusion would be fantastic but possible a case of over engineering

1) Hinkley Point C is expected to deliver power at $0.024 per kwhr. That's cheap
2) Rolls Royce SMRs are expected to deliver power at $0.04 per kwhr
3) TerraPower have a similar technology to Rolls Royce and can use the waste from reactors like Hinkley point C. The estimated fuel source is just over 5 billion years.

If available technology is cheap, safe, negligible waste and more fuel than solar............I struggle to see the advantage. That said, it's always great to achieve.
 
This group is opening discussion with notable AUSTRALIAN govt agencies

It is designed to replace remote diesel applications and deployments


$0.06 to $0.10 per Kwh
 
A cut and paste from an off the record source


“A related rumor is that a third national lab (along w ANSTO and CSIRO) might emerge, this to support nuclear submarines; with Both players trying to bring it all into their shops.”

This sort of thing is why I'm a techno-optimist when it comes to climate change and power problems. The need will spark the invention.
Of course it will.
Yet we have a happy clapping coal waving science denialist in charge.
We have all we need to get these types of ideas off the ground, happy clapper will die trying to stop progress, whilst trying to pass “laws” to stop a woman whom likes kissing other women, so she can’t care for old people, because “religious freedoms”.

Why's it always gotta come back to religion and the PM? It's boring man.

You’re boring.
If we had leadership that waved a ****ing solar panel in parliament and said **** god, then maybe you’d have a point.
Until that day, you don’t get to wave your coal in my face and tell me I’m persecuting you.
Ok matey?

What? I don't think you understand. I'm just saying you keep bringing absolutely everything back to religion. I've no idea how you can be so driven by such a single-issue concern. I'm not religious - I couldn't give a shit what your view is. It's just boring to hear it again and again, particularly when it's a tangent or out of context.

If you couldn’t give a shit, why did you reply?
It’s completely in context, when a country that has as its leader, that waves a lump of coal around in parliament, as his privilege, whilst sending “thoughts and prayers” to the drought affected farmers and bushfire ravaged.
If he spent half his time working on new economic growth and driving thought bubbles about the future, rather than singing with his hands raised every Sunday morning, perhaps you’d have a tangent in context.
Until then....

You thought you were having a go at me because I was religious, but I'm not, which is why I replied. And also why I don't give a shit.

Your repetitive everything-is-a-chance-to-shit-on-religion schtick is old and boring. I can't believe you aren't sick of saying it yourself at this point!

I mentioned how the future tech being developed is cause for optimism. In you came with an attempt to insult me that missed the mark by a mile and you wonder why I'd point out how dumb it all is? lol

Have a good weekend matey

for the record, he was holding metallurgical coal
 
Off-grid Solar would be a good solution. That way everybody uses exactly as much electricity as they harvest.
Yep, and then if I harvest more than I need, I could perhaps package up some of it to sell to others at a price that we both find agreeab... Wait...
