Canada

I've had too many mind numbing conversations and I think many are afraid because it can't be literally 10,000% safe. That somewhere, somehow, somewhat, anything, possibly, could, maybe, anything built by man may fail. Therefore!1!1

Every single point here is the same issues that go into every industry, especially important ones like energy. And nuclear is a far better option compared to any fossil fuel industry anyways.

Besides, the more electricity we generate, the less excuse we have to rely on natural gas for heating, which is one of the top sources of carbon in Canada. Thankfully because hydro generates like 70% of all of Canada's electricity, but there's a serious limit to that considering that most of that hydro is generated on the Eastern half of the country and the prairies have almost no waterfalls.

Some people live near the plants and watch the grift and excess through the fence. The nuclear industry in Canada is a jobs program. "Hide and seek for 2 grand a week"

CANDU is one of the best reactor designs currently running, in my opinion. The problem is that it's expensive to build, and requires expensive maintenance, and in a world that loves to cut corners and find efficiencies that is not popular. But it is solid, it is safe, and I support many more of them being refurbished, maintained and built in this country despite the cost.

Advanced CANDU on the other hand, had little in common with CANDU despite the name, and bowed to all of the previously mentioned pressure to cut corners and find efficiencies resulting in a dangerous and ultimately non-viable design that basically killed Canada's nuclear industry. It was a classic boondoggle, and while I was and am infuriated with the way Harper killed it and put it out of its misery, the real mistake had been pursuing it down that path in the first place which was a decision that came well before his time and was based on global circumstances that made it simply impossible to justify.

I would love to see even more advanced reactors being researched, designed and built here, modular, pebble bed, sodium, thorium, all of it. But sadly I think that is mostly unrealistic given the current state of our nuclear industry. CANDU is however at least one proven technology that we can and should continue to take advantage of. Even if we will probably never be nuclear leaders again thanks to the mismanagement and sabotage of our nuclear industry, at least we can cling to its legacy.

TBH the Wheel of Pain is low carbon emissions

Can't say I agree with this at all. The thing about fission that people regularly mistaken about is how much actual waste there is, and how little of a deal it is. Not to mention that all the safety processes and security issues that you mentioned had been solved since the 70s or so. I mean, there's never been an incident in the entire world regarding nuclear fuel or waste being stolen. Only nations have ever produced a nuclear weapon, dirty or atomic.

And in regards to waste, the amount of high level nuclear waste that's been produced world wide is only a few dozen tons, all of which can be recycled and reused, cutting down the half-life from millions of years down to only a bit above 200 years, and reducing the total quantity of waste to only a fraction of the original amount. I mean, when people throw around all the nuclear waste numbers, they include low level waste as well, which include things like the radiation suits the workers wear while working near the reactor. Waste that become non-nuclear waste after a holding time of two months and are generally tossed with the trash like normal.

In addition, the worry about natural disasters is entirely a red herring for most nations that build nuclear reactors in the first place. The containment building of a nuclear reactor is designed to survive an actual missile strike. You could have a 747 dive bomb the nuclear plant, and it wont' crack the containment building. Nothing short of something on the level of a US bomber squadron dropping an entire flight of bombs, or a conventional nuclear weapon, directly on the plant will crack that thing. No natural disaster short of a magnitude 10.0 earthquake or a volcano sprouting underneath the plant will cause any decent nuclear plant to leak radiation.

And if you're going to mention Fukushima as a counter example, then let me remind you, that it took a direct hit from both an earthquake and a tsunami to disable the plant (the containment building didn't even crack from that), and the backup generator room drowning for a good 2 weeks without a single nuclear technician not being able to enter the entire city for that duration before the critical explosion happening. The damn reactor, a design that was considered flawed due to putting the generator room underneath the plant instead of above it like the original recommendations to lower the risk of terrorists that the US was worried about in the 70s in a nation without a history of terrorism before the 90s, managed to survive without power for its cooling systems nor any technicians to repair anything for 2 weeks. And to make matters worse, the Fukushima plant was actually slated to be retired a decade before it due to being too old, but was pushed to stay online until a newer plant could be built, so it was even way past its decommission date on top of every other factor going against it. And the worst that happened was a slight elevation of radiation for that one year, and the current discharge of tritium that is magnitudes lower than the amount that pretty much any nuclear plant discharges during normal operations. Far lower than the amount that anyone who sources water from Lake Ontario or the St Lawrence drinks on a regular basis, for example.
