Luckily Dutton's pro-nookular arguments are likely to blow up in his face long before we ever build anything than can blow up more seriously. He clearly subscribes to the Trump model of ignoring any inconvenient facts that get in the way of his agenda. I'm glad to see that the CSIRO guys scampered into the net and volleyed his idiotic comments straight back at him.
Before seeing Dutton spouting his crap on TV, I used to think that builders were the only people who would tell a lie to your face even in the sure and certain knowledge that they'd be called out on it inside 10 minutes... "Yeah, mate, it's supposed to be like that. Nothing we can do about it now." :rolleyes:
I was reading an update on the cost blowouts, delays, etc. with Snowy 2.0 a couple of days ago - and that's mainly just digging holes !! I don't rate our chances of being able to build a nuclear reactor without having "a few bits left over" and generally stuffing it up. Given our history with large civil projects, I'd say you could take any cost or lead time quoted and at least double it.

I look forward to reading the thread on your Norway experience should you do that.
To those participating in this thread, may I once again thank you all for setting an example for how discussions with sometimes opposing points of view should be conducted. Although I rarely contribute (mainly because I usually can't do so meaningfully) I follow this thread closely. I may be none the wiser, but at least I'm better informed.

ETA Brisbane some time this year.

Some time ago I posted on the small Hydro Station behind where my son is living in Norway. Well during our visit I saw the station in the flesh, although only from the outside.
It turned out that the station is owned by Simon's landlord, who lives next door, in partnership with a company that specialises in these "micro" units. Bjorn, the landlord, said that he had keys to the station and he could get us in. This was not surprising as he runs the station, from his phone. However, it does not operate during the winter as the dam, which is situated 140m above in the mountain behind freezes over and any precipitation becomes snow. There is not enough water during that time.
This is the lead up towards the turbine building:

I had made the short trek and had a look around. The snow was over one meter deep around the building.
Attachment 536447 Attachment 536448 Attachment 536449Attachment 536450
Initially I had walked up there but when Bjorn went up, he travelled on this:
Attachment 536451
Just a quad bike and for summer the standard wheels will go back on.
And this is the data. Commissioned in 2016, a 140m head, 1.6MW maximum capacity (For comparison, our electric feedwater pumps at Millmerran are about 4MW and at Bayswater the electric feedwater pumps are over 9MW) and a potential of 1400l/sec. The suction pipes from the dam are underground.

When we went back, we still couldn't get access easily to the turbine house because what looks like snow, and is, becomes ice further down and not so easy to clear away. The door at the side was blocked. However, the second time I did manage to gain access to the front window to take a few pix of the Hydro Generator:

The arrangement with Smalkraft is that they build the station (and the concrete walled dam) and Bjorn runs it. The monetary split is that for thirty years (this period may vary) the land owner gets 10% and the company receives 90%. After that ownership reverts 100% to the landowner. Of course, the question there revolves around what state the unit is in after this period of time.
These are the power lines (two different voltages) running nearby:
Attachment 536442
This is the connection to the grid on the lower voltage. I did not get to find out what that was:
Attachment 536443
One thing that confused me was this building coupled to a weir just downstream from the turbine house:
Attachment 536444Attachment 536445
It turned out to be nothing to do with the Hydro plant and was a fish spawning facility. It had fallen into disuse and not operated for twenty years.

Paul,
Very Interesting - keep posting.
BTW most of the attachments are not showing up. I think you may have linked them to your PC or phone and not actually uploaded them OR they are the wrong format ie not JPGs etc.
Thanks Bob.Quote:

That building is fabulous. Most countries would have built the cheapest, ugliest building possible. Not Norway!Quote:

I have mentioned so many times that every electricity source has at least one fatal flaw readers of this thread are probably rolling their eyes even as I type. So it is in Norway with their hydro. In winter water freezes and inflows to dams are restricted as the precipitation falls as snow. Consequently, there is still a balancing act to be performed.
The grid in Scandinavia is linked and also to Europe. When prices are low in Europe (Lower than in Norway) they buy in power so they can conserve their own resources. The adoption of electric power replacing traditional oil means their demand is also increasing far more than before. I saw a statistic that gave the per capita electricity consumption at twice that of the USA for example.
This link gives some insight to the way they manage the resources:
The power market - Norwegian Energy (energifaktanorge.no)
In particular there was this:

Very sensible, and exactly the approach what I'm expecting from Voldemort.Quote:

I note he has backed away from the SMRs so somebody must have mentioned, in passing, they are pie in the sky. He may be relying heavily on the great unwashed's lack of understanding of such matters. If he continues down the nuclear path, he will look foolish. An alternative policy is good policy, providing it is relatively sound.
Perhaps he does know the flaws of nuclear, but is trying gain an extended lease of life for fossil fuels by touting a, for the moment, non viable alternative.
