Top 3 MOST Popular Nuclear Reactor Types Worldwide

Out of the 440 Nuclear power reactors operating world wide, there are three designs that are most popular. The PWR (Pressurized Water Reactor), BWR (Boiling Water Reactor) and the CANDU (Canadian Deuterium Nuclear Reactor). In this video, I'll be deep diving into the basic features of these reactors and explaining both their differences and similarities. What sets them apart and where can you find them across the world?

GRAB A COFFEE WITH ME
☕ I love meeting up with people in real life (and Virtually). So here's a standing offer - if you fancy taking a trip to Toronto (Canada) and want to chat, I'll buy you a coffee, no questions asked. I'm generally available most weekday evenings after 7pm.

Production value 💯 nicely done. Would love some CANDUs in the US!

[davidwilkie]

Very good, brief but sufficient to make the distinction between types.

[tomaskabele]

Great video! Simple, but informative! Thanks for the video

[capoman]

I'd love to see a followup video that compares the dangers present in each, how they are addressed, and what waste management looks like.

CANDU sounds like a Chinese shopping 🛍️ app🥹.

[zerochance]

I will cite you in my seminary work concerning nuclear reactors types. Thanks a lot for such clip.

Fantastic video. I think the only thing I would have liked to see added were some more details about why some features were used. For example, I am rather curious to why BWR use control blades rather than control rods, and why they are inserted from the bottom. Are there benefits to these? Or is it a way of accomodating for other aspects of the reactor?

I do also have two questions about the CANDU reactor that I have been trying to find an answer for, but have had no success.

The first regards a safety feature. CANDU reactors needs to have it's fuel assemblies lined up in just the right way to work, and if the reactor overheats the fuel channels start to sag breaking the alignment and slowing/stopping the reaction. Is this from thermal expansion of the tubes, a decline of the structural strength of the tubes at higher temperatures, or a combination of both?

The second thing that I am curious about is the positive void coefficient that CANDU reactors have. From the little I know about nuclear reactors, I don't see why CANDUs should even have them. I guess what I am asking is why is there a positive void coefficient? And to what degree does it exist? My general impression with the whole thing is that it's more of a trivia tidbit than an actual concern, but I have seen activist groups complain about it more and more and I don't know how to address it.

Well, we should definitely know one of the least used Reactor Models, and that’s the RBMK Reactor, which is the same type of reactor that Infamously Exploded in Chernobyl.

[scottmedwid]

Excellent summarization! Keep up the great work

[joeltell]

What a great video, Candu all the way!

[heyyo]

What is the reason for the CANDU to have so many independent pressure vessels OTHER than the ability to fuel them while the reactor is running? Isnt it cheaper to just have one common pressure vessel for all fuel assemblies?

[redneckReno]

do you have to voice that emission disclaimer at the top of the video to get you channel monetized?

Very nice, thank you, verbal, no music.

[DanielWhalen-mw]

Are there any Sodium Cooler Fast Breeder Reactors or any Gas Cooled Reactors operating in the word?

[tchevrier]

personally I've always thought the Candu was far superior to any of the others.

[Satelite]

Excuse me if pwr is pressurized water reactor and bwr is boiling water reactor whats an rbmk?

[MrAdityams]

Can you do a video on fast breeder reactors

[lukas.prochazka]

Could you make a video that would compare CANDU to RMBK reactors?

[mattr]

Great information. Thanks for educating me

❤ nice video i ever saw for nuclear reactor . I am from india our Bwr and Pwr russian reactor performance is awesome 👌.
