Reactors of the Future (Generation IV)

Difference of the future reactors, generation IV, from the ones of today and how they may be more efficient by running hotter with less down time, and safer. High-Temperature Gas-Cooled reactor, Helium-Cooled Very-High-Temperature reactor, Lead or Salt cooled reactor, and the Pebble-Bed reactor, are all described.

The most impressive part of this video, to me, was the professor's ability to write backwards. Incredible!

_"Did the marker have its own mic?"_
No, a foley artist dubs it in during post production.
I believe they use a mouse.

[hynesie]

His backwards writing skills are next level

“Down to a couple of weeks” I work as a nuclear contractor in the us and I can confirm that. 4 week jobs are considered long within my craft

[sonofsomerset]

Meh, I'm gonna wait for the Gen V before I get one.

I still remember walking into a fast breeder reactor in India, it was a school thing, also got to see their largest electron scanner device for finding defects in large metal structures.

[stephanfuhrmann]

I believed pebble bed style reactors died after the big problems of the THTR-300 in Germany. Interesting to see that these concepts are being worked on again.
Thanks for your outstanding videos, professor!

[hvanmegen]

Damn, this channel is a gem.. subbed!

[brianburk]

That was one really good aspect of the RBMK. Being able to fuel it without shutting down

"As long as we have an economic imperative for the future, these could be the reactors of 30 or 40 years." Can someone get this man a larger microphone.

[peachtrees]

This was awesome. Thank you for putting this together. Hope you do more of these!

[kahuna]

You are a very good explainer of difficult subjects. amazing stuff here.

[stupidburp]

Expecting to wait at least 30 or 40 years is a defeatist attitude. Some of these designs have already had functional research reactors built a long time ago. All that is required is the will to build a pilot commercial reactor and then copy it. That could be done in less than ten years if we make it a priority or it may never happen if we don't.

I appreciate the professor's online mini lectures. Thank you for doing them! I feel one major advantages of Gen4 wasn't touched on strongly enough. It seems to me most (but not all) new nuclear is smaller startups employing molten salts. Configurations or design ethics to eliminate nuclear waste by using it as fuel. That's a political problem solved. Pebble bed makes this goal harder by making the waste really hard to process. Simultaneously, using liquid fuel jumps the efficiency to near full efficiency, rather than nearly zero. Most of the transuranic actinide fission products burned away, most of what's left is valuable material able to be sold. What's left of waste won't matter in it's quantities or lifespan.

Whoever came up with that pebble bed design is a damn genius.

[pmdurand]

I would be very interested in learning about small modular reactors, Could you please make a video about these ?

Next episode: Pens Of The Future
Same efficiency as today's pens, but without emitting a sound that stabs your brain.

[seedcraftthree]

The advance from current nuclear fuels to the new pebblebed method reminds me of the advance from musket balls to bullet cartridges...this was very educational by the way, thank you

[lorriecarrel]

I love listening to your videos, you do such a good job breaking it all down.

[mikeknecht]

I wish I had you as a prof. back in the 80's
