For goodness sake, leave the politics out of it and the money interests then look at the science.
Technology currently exists that can solve all the problems of the world except greed and egotistical desires for power.
Tell that to kami, what he's proposing is inherently political. He ignores the fact that it's expensive because it proves(to him) that lefties and greenies and commies are full of ****. The truth is nuclear will be leapfrogged by other more renewable methods.
^^ Simply because of economics. Renewables are cheaper and much faster to deploy.
We can build 1GW+ solar farms with 500MWh storage in under a couple of years.
We couldn't design a 1GW nuclear plant in that time, let a lone turn a sod or enrich the fuel.
There are nuclear power plants of this capacity currently running at a financial loss and that will increase as renewables demonstrate the primacy of capitalism.
For instance, I don't see any banks lining up to fund 11GW coal or nuclear powered plants in Australia but I do see them funding 11GW renewable energy projects:

Interesting that nuclear proponents implore us to embrace technology but when it comes to advancing truly sustainable technologies like renewable energy they balk and claim it's all too hard.
Hypocrisy.
Yes, that's the sort of argument that tells you something is emotional and not based on logic.
Even so, I think renewables are an emotional topic, but maybe they should be if they have the potential to improve the world and are still economic.

I think renewables are an emotional topic,
We live in interesting times .Things like clean electricity , water essentials could become boring topic very soon.From all problems facing humanity those possibly the easiest to resolve and we have almost all technical means to do so already.This is just a matter now to implement those. We don't need to wait to resolve Fusion concodrum while to comes to solar panels. There are already here, available and cheap as dirt. Battery storage _ predominately for those stationery use are not rocket science too (unlike batteries for airplanes that are still a decade away) .Summarizing: we should be happy that we could be emotionally involved in such prosaic topic like energy and water, because subject will become obsolete in few years . Like air to breath. It is just here and nobody bother.Those teething problems with reliability of renewables will be resolved soon simply by mass market. Slowly comes to the mind of decision makers that solar or wind energy is not confined to plain solar panel but require whole infrastructure like battery condensers to rectify fluctuations and transmitting lines. Like Steam engine that is useless without rail roads. DC HV or even superconducting is obvious solution for long term future. The problem for scientist and engineers to resolve and decide if existing AC network is what we need, or we may need complete redesign of whole grid and network to DC. Seems obvious the while you switch to DC all existing problems with 50-60Hz sync, voltage fluctuation - remain obsolete/ rosolved instantly while you switch to DC.In such case end user will need inverter to convert DC to AC for home appliances- until those could be also DC capable.So after century of Tesla , Edisson could win the future anyway!
The problem with switching global electric grid from AC to DC is similar to those with Imperial vs. metric. The longer you wait the more difficult it becomes. In in incoming era of superconducting AC doesn't seems to be the option ( unless we could design superconducting AC channels) .We could be specifically interested in superconducting infrastructure for planned network in space on Mars and Moon where low temperatures already favour DC superconducting lines.

Obviously can't do anything with wind/solar in six years either. I mean, it's not like it's a big job to layout some panels on frames.
Y'know, the more I look into it, PV cells should not be classed "renewable". They have a finite lifespan and ever decreasing generating capacity then they have to be "recycled", assuming that's even possible -- or economically feasible.
You're still not going to get 100% steady power generation out of "renewable". Estimates range from 30 to 80%, versus 90 to 100% for nuclear day in, day out.
"Politically feasible" is the operant phrase there. With bull**** mongers like Greenpeace leading the charge against the most effective and greenest form of power production, you'll be stuck with what is "politically feasible" regardless of how "economical" it truly is. Never let the facts get in the way, eh?
Not in the nuclear industry, but it doesn't take a PhD in nuclear physics to spot the yawning chasms in your arguments.
Let's talk about nuclear power
First we will talk about ****ushima and Chernobyl.
Than we will talk about the radioactive waste it produces which cannot be stored.
Thorium may be an option as there are uses for it after however again we are not quite at that level of managing it.
Our skill set in Australia also lacks the depth of knowledge to build operate and maintain a nuclear power station, our power company in west oz cannot even maintain the network of poles and wires let alone be put in charge of a nuclear power plant.
When we talk about renewables such as solar and wind power , if we invest now and properly the efficiencies and pricing will get to a point where it is so cheap and readily available that it will steamroll any other option and become so economically viable we as a species will be kicking ourselves we didn't do it 50 years ago.
Okay so maybe we cannot quote recycle solar panels properly as yet, sure beats trying to store nuclear waste for 500 years.
Yes it's new technology and a bit inefficient, invest in our future now and our kids kids may be able to breathe air as clean as we do.......
what do do we lose if we don't do it..... well quite a lot actually

It's a set. You can have slightly more green power generation but it's nowhere as effective.

They're not.
And from your own link up there: $22 billion would get you three nuclear plants producing as much power far more reliably.

Are you entirely sure that the loss of generation isn't due to a variation in cloud cover, atmospheric moisture and dust?
Anyway, it is well known that solar panels slowly lose efficiency as they age. You can accept the loss for as long as you like. After a century or so, I imagine that they might have dropped to only 20% of their initial output. By then the rest of the roof will need replacing and there will be a mature recycling route for the panels.
I don't get why people don't get that solar energy is limited by the ability to store it. The argument is not about renewable V dispatchable, its about how much renewable we can realistically put into the system.
Solar is a viable contributor to the Energy network, but it's effectiveness declines rapidly when it hits a certain %. After that you need dispatchable sources (coal, gas, nuclear). There are no realistically effective means of storing renewable energy on a scale large enough to meet all our energy needs. These are simple and verifiable facts.

Dunno who you're talking about, but I understand that.
We may store it in batteries, pumped hydro, superheated molten salts and as hydrogen. The options are there.
Hydrogen can be exported like LNG is now. If we don't do it, someone else will.

But none of those options are actually feasible from an economic or technological viewpoint.
I'll reframe your comment from above in the context of those solutions: "A gamble would be for Australia to embark now on adopting a pumped hydro, superheated molten salts and hydrogen" They just are not actual practical solutions from either a technology or economic viewpoint. Maybe they will one day but not now or the near future. Except for pumped hydro, that will never work here on any scale.
I agree Nuclear has some economic challenges, but those challenges are mostly regulatory. A robust regulatory framework and a partnership with someone like South Korea to build the plants would actually make it cheaper than any of the options you have put forward.
Nuclear is the safest and cleanest form of energy per watt than any other source, including renewable. It may not be renewable but it is certainly not putting a burden on the environment. And despite what you like to think, no renewable energy is actually fully renewable. The cost of building and maintaining the facility to capture the energy generally has a high cost too.

You have totally missed the point -- we're talking about high voltage DC here, which is able to be converted to low voltage DC using electronics now.
AC used to be the only way to get high voltage, because transformers only work with AC. However now we have electronics that can do the same job as a big heavy transformer, which means that high voltage DC transmission lines are now possible.
Transmission losses are dependant on current, not power, which is why high voltage is used on transmission lines.

Don't understand that sorry, do you mean economies of scale? Cos that applies for nuclear as well.
You keep switching between blanket statements about nuclear power and what is suitable for Australia, with little trip wires like "proprietary systems" tucked in the middle.
If it isn't already clear, I'm not advocating that nuclear if the best choice for Australia, I simply don't know any more than you know it isn't. That nuclear is the wrong choice always is where you are wrong.
"Proprietary systems" sounds like an acknowledgment that you can get off-the-shelf nuclear solutions and cut down your imaginary drawn-out design phase

I noted the post denying the statement that Nuclear is the safest and cleanest. It's gone and I will assume you actually did a bit of research on it and realised I was correct. That's great, knowledge is a wonderful thing.
It's safest by a long way. No amount of selective googling will deny that. There are many studies on cleanest, some put hydro and wind ahead on per KW CO2 emissions, some put nuclear ahead. Suffice to say they are all pretty close on a very low whole of life CO2 footprint.
For a bit of really good reading try this: www.carbonbrief.org/solar-wind-nuclear-amazingly-low-carbon-footprints
"The study finds each kilowatt hour of electricity generated over the lifetime of a nuclear plant has an emissions footprint of 4 grammes of CO2 equivalent (gCO2e/kWh). The footprint of solar comes in at 6gCO2e/kWh and wind is also 4gCO2e/kWh."

So HG's 11Gw renewables station is down to 1Gw peak, while the nuclear has been pumping out 100% of its capacity day in day out.

Yes your safety and clean claims are questionable. Depends who does the study. Depends on whether you factor in waste and toxic accidents. I removed my post because I realised you were referring only to greenhouse gases. Obviously if you take into account all issues with nuclear it's hardly the safest or greenest. Nothing to do with research.
Depends on what you mean by safest. Is that number of deaths per MWh produced? If so yes, nuclear power is quite safe...until it melts down.
So when a plant melts down and pollutes large areas of land, the fractionally lower greenhouse emissions don't seem so relevant at that point.
Cue claims that anti-nuke people always bring up accidents but.....sorry, there is a history. Fuuuku is still being addressed now with no end in sight. Depleted uranium is placed into weapons and used on warfare, leading to all manner of horrendous disfigurements in babies etc.
Sure blame earthquakes and tsunamis....
It's certainly not the lowest cost and probably never will be.

high voltage DC here,
one day when technology mature ( and people too) we could see solar panel arranged in such way to deliver high voltage DC without the need for any inverter. We could connect solar cells in series to reach very high voltages.
Too early for that now because high voltage DC in this arrangement will be quite difficult to handle safely.But for Moon and Mars colony that could be first thing we will do.BTW
Instead of talking about nuclear nonsense we could do something useful and realistic. HVDC lines across Australia seems to be doable task. Realible transfer lines at high power capacity that is what the country need the most. Electric energy is usually always available somewhere is Australia, but we don't have means to ship from one side to another. Electricity is possibly the easiest of all to transport, don't need pipelines, rails, trucks, ships just a piece of conductor cable.The main problem Australia face in energy sector, is not lack of electricity but inability to ship it from place when can be produced to place when can be utilized. We could build aluminium smelters ( or any other electricity hungry plant) in Adelaide and use energy manufactured in Queensland. Future development of this renewable energy sector is already compromised by lack of industry able to use it. All we could think about is packing this energy and sending overseas for others to make a good use of it.The main problem solar farms already face is lack of demand for their electricity.

I thought you were the one primarily concerned about the toxicity of nuclear?
The toxic chemicals in solar panels include cadmium telluride, copper indium selenide, cadmium gallium (di)selenide, copper indium gallium (di)selenide, hexafluoroethane, lead, and polyvinyl fluoride. Additionally, silicon tetrachloride, a byproduct of producing crystalline silicon, is highly toxic.
