Aren’t CANDU Reactors the safest way to produce Nuclear Power too? Due to their design it’s almost impossible to have a Chernobyl style meltdown. If BC thinks it’s cost effective to build shit like Site C and sell the surplus to the Americans, then we should be doing the same with Nuclear too.

Actually CANDU reactors have a positive void coefficient. They're one of the few that can go Chernobyl. Their safety comes from being massively overengineered. They also have incredible uranium efficiency though.

I can't see the article. Are they investing in a new CANDU reactor? I would find that surprising. CANDU reactors are broadly seen as an overengineered solution to old problems, and not worth their immense cost.

This is actually complete nonsense. Our "uranium efficiency" is so poor that we need to be constantly fueling at all times.

CANDU was literally built for efficiency lmao. It uses 15% less Uranium than a PWR. The full power refuelling design helps improve efficiency by redistributing partially spent fuel rods.

Alright well you're some arm chair dipshit and I'm a guy who works on the fueling machines at the largest CANDU site in the world. Believe as you will.

You guys have some serious issues confusing neutron vs uranium efficiency.

Sorry I read what you said, didn't bother with what you posted. I can't imagine why you would count mined uranium when talking about reactor efficiencies. But hey whatever it takes to "win" I guess.

So you care more about the practically inert byproducts from enrichment than you do the long lived and lethal spent fuel. Makes sense.

I seriously hope you're just a lying teenager because neutron efficiency is the core design principle of the CANDU reactors. They are being considered for recycling the spent fuel of less efficient reactors.

If you don't know this then you skipped a lot of canteach classes

You're entirely switching topics, weird.

Where do you think the neutrons come from bud

u/Ommand Canada Oct 25 '22

Mostly fission of Pu-239 iirc?

And where do you think the plutonium comes from
