I am baffled why Canada don't have massive data centres yet? It is cold with abundant water and energy. Why not?

Alberta has energy. Canada wants energy without Alberta. The Candu reactor program is so defunct that the feds have been trying to sell it for about a decade. Candu makes plutonium and was responsible for a lot of nuclear weapons proliferation in the 1980s, but again, Candu isn't Alberta. Also it's a way to spend an enormous amount of money, and Canada isn't quite bankrupt yet. I say go for it.

From what I've seen out of Canada, this is likely overly optimistic and probably will not be possible in that time frame.

I think it's better to just outsource it to Koreans at least that way you can stay on budget and on time.

So we're willing to put our greatest national asset (the environment) at risk in the name of "moar power". Well that's just great.

I hope Jimmy Carter's ghost will be just as willing to help us out the next time a reactor goes into meltdown as his physical self was the first time that happened. RIP Jimmy Carter.

The Ontario government is terrible at creating a structure which is capable of finishing any infrastructure project on time ...(see Eglinton Crosstown) and mostly seems to work as a funnel for moving public funds through public-private-partnerships to feed contractor/consultant income for projects that grow to many multiples of their time and budget.

So, yeah, it makes sense that they love nuclear now -- blank cheque to drag on for multidecades over budget. Likely the right people donated the right funds to the PC party and/or attended/funded Ford Fest

The first thing this government did when it got into power was pay out hundreds of millions in penalties for cancelling large wind projects, and for breaching its contract and exiting the cap and trade agreement with California and Quebec.

Ford loves to waste money and then wag his finger about how everyone else is fiscally irresponsible.

Darlington nuclear refurbishment finished ahead of schedule and under budget

Yeah the last decade of Nuclear work is the ONE thing that they have been successful at wrt to project planning.

Hopefully that expertise is well placed to execute on these other projects.

Nuclear industry in Canada is federally-regulated, not provincial.

The regulation of it is an entirely different thing from the budgeting and promotion of it. Promotion of nuclear power has become a very vocal Ford government thing in the last few months.

That’s great news ! Have they also solved the nuclear waste problem?

Honest question; here in the USA we have not.

It's not really a problem. The alternative is to grind it up into fine dust, spray it into the air, and call it "clean coal".

Excuse me that's "beautiful clean coal" I still can't believe that you guys actually chose him as president.

That would poison the entire country. Nuclear waste is many many orders of magnitude more radioactive than coal per energy generated. The meme about coal emitting more radiation comes from a 1970s paper that compared radioactive emissions and found them to be on the same order of magnitude between a BWR and an unfiltered coal power plant.

Im surprised they haven't doubled down on deep drill geothermal.

not least because of the bureaucratic delays making nuclear slow to roll out.

Totally unnecessary : I did the Math to cross-verify - Elon Musk is 100 % right !

Just ONE square mile of batteries and a TOTAL of 100 x 100 square miles of Solar can power the entire USA 24/7. Area required will be much lesser for Canada.

How convenient for Musk that technology connections did this exact topic and these exact calculations (and much more) as a topic months and months ago: https://youtu.be/KtQ9nt2ZeGM?is=wOjIwPKFuYj2Smrh

Why up Musk? Is he your primary source of news and ideas?

But what do they do with the waste? And how much fresh water is that going to use?

> But what do they do with the waste?

The Canadian Shield [0] is uniquely well-suited for this: it's remote, sparsely populated, and geologically stable.

Leaving aside that Canada is huge, waste is really just not that much of a problem. It would be easy to safely store all the waste that will ever be produced at a dedicated storage site, if you could drum up the political will for such a site to exist. But really, it's even easier to just store it all on-site. Not that much waste is produced; stick it in a cask and leave it alone.

I agree with the rest but on site storage of high level waste is a terrible idea. Even after vitrification that's material that will remain dangerously radioactive for longer than agrarian human civilization has existed. Ideally it should enter a disposal chain that keeps as little of it at ground level for a short a time as possible in order to hedge against the long tail possibility of a large scale disaster stranding it on the surface.

I think the finnish plan to bury it on site 500 meters down in bedrock is a decent one.

This is why I always scoff at people talking about the scarcity of landfill space. We have damn near unlimited space here. It might not look like it if you never leave a major city, but if you drive up north you will see nothing but trees forever.

The only hard part is ensuring your waste doesn't enter the water system, but that's just bog standard mining engineering.

Problem is you'll get some tribe coming out of the woodworks claiming whatever inaccessible area hundreds of miles from civilization is some sacred ground that can't be touched.

If there's something Canada has in excess it's water and storage space.

This is a problem that can be handled. Finland handles this pretty well IMO as one example. Also Canada is huge. That means lots of potential places (most Canadians live on the southern parts, close to the US border).

The sun uses much more water on earth than people do.

I think most (all?) nuclear plants use once-thru cooling. There is a water intake upstream (or in an ocean/lake) of the plant, the water passes through the cooling loop interfacing with a heat exchanger that has hot heavy water from the core on the other side. Some of the water is evaporated in hyperboloid cooling towers, and the rest is discharged downstream (or back in the ocean/lake)
