First reaktor in Czechoslovakia was CarbonDiOxide cooled, heavy water moderated using natural uranium,...

No word about the THTR-300 and it'sproblems? It was a high temperature graphite moderated, helium cooled pebble bed reactor.

please be aware that the russians have operated the BM 300 since 1983 (!) and the BM 800 since 2016. both are sodium cooled fast reactors. So, feasibility is high, we can build these things. Fance has Phenix and super phenix which could have operated very well by now (but were closes by the weird green politicians)

Damn, I hate to admit it, but I'm jealous of all people studying at MIT... only if I studied harder when I was young, I could be there... :/ But awesome videos, I can have a taste of heaven.

It's a pity the didn't go on with MSRs all over the world. Gen3+ PWR is not far from Gen1 or 2, although they have some added safety features and other things. So far only China really made progress with MSR based on thorium cycle, they should put online 2MW design this month and go on to ~100MW until 2030. I believe they will because their culture supports advancements like this. I watched another lesson by dr. Short from 2020 or so, he got really good at it.

Hi from Scotland. Your educational geography trip has been approved. Come and visit 2 of the remaining 7 AGRs which at NOT in England! You're right though, the politics of the winning design is fascinating...

RBMK is actually an elegant design with a lot of good things. Shame the Soviets ruined it by putting incompetent people in charge of a bloody nuclear reactor. Chernobyl was one of the worst accidents for humanity. Not because of the radiation release, but because of the stigma it brought onto nuclear energy and the damage that has done to the climate.

About the HTGR i would say they fesability gone up quite a bit since 2012. China installed the first actually reactor last month, and Iran have ordered 2 of there own from China. The time to build seams to be around 3 years, that is pretty fast. And its also have a decent capacity of around 100MWt. The BN-600 was finished in Russia in the 1980-tys: The BN-800 was finished 2014 (so two years after this video). It seams to work fine and is producing power commercially today. The BN-1200 designwork is nearly finished and they plan on start building it 2020 or something like that. (the BN-1800 design seams to be scraped) Also the VVER-1700 also russian reactor is a supercritical reactor, very simular to the current VVER reactors, but super critical. Designwork is ongoing and there supose to be a build start soon (a few years), but not solid date yet. There is a lead reactor project ongoing in Canada. They will build it quite soon, but i don´t know when the first prototype will be built.

If only the DOE was looking into MSRs. Based on the info from tours of ORNL, they are giving away the tech, and ignoring it instead favoring pebble bed & TRISO fuel, as well as some dabbling in SMAHTR modular reactors. In addition they are destroying or have destroyed the U233 generated decades ago which could have been harvested for useful materials or used in new MSR designs as clean startup fuel (no transuranics). Ah well. Good class, nice to validate the info I've gotten & see the designs.

Very good lecture by the MIT NSE Dept. Think Prof Short's a bit too much in love with his pointer HA HA!

The innate promises of a pure-math Polar-Cartesian self-defining universal system of Gold-Silver Rules, is that understanding this connectivity is to automatically argue with, not against an individual, together towards coherence-cohesion objectives, a parallel coexistence in/of vertically integrated holographic resonance bonding, perspectives vanishing-into-no-thing. (We don't need another Hero) Excellent Teaching of the technology.

I live between OPG Pickering and OPG darlington. I fish the warm water outlets from candu plants all the time… massive carp love the warm water and massive pike and Muskie hang out on the edge of the warm water picking off food.

Superphenix in France was operational for only a few days out of its twelve year existence. It had too many technical problems. Its predecessor, the smaller Phenix WAS a success. The French are apparently working on a new Sodium Cooled Fast Reactor. Personally, I don't like even the IDEA of a heat exchanger, which has sodium on one side, and water on the other.

Awesome. Loved it. When you mentioned Lithium to Tritium I made a face, paused it and sat counting protons and neutrons on my fingers trying to work out how that is possible. The only thing I could come up with was that if you subtract tritium from lithium + n, you are left with Helium. Anyone know, is this an split due to the neutron kenetic energy or is lithium 7 unstable and alpha decays to Tritirum? The later sounds more plausible.

RBMK - РБМК - Реактор Большой Мощности Канальный and yes, a lot of these reactors are still working (in CIS)

Very cool lecture; thanks for posting this.

Agr are huge things.they don’t do online refuelling as planned and due to the fractures output is limited.

That was nice

Interesting class. You have a student pub called Asgard? Damn, I should visit! :-)

ORC power from the waste heat ? Economics ( time to build ), (loans, cost over time), ( time to break even) Current nuclear plants take about 6 year for construction with a very large investment required before power generation begins. Politicians just do not last long enough and have short time though processes . Orbital thermal or PV designs would have the lowest environmental cost. Fusion power has far to many materials and control issues. Nuclear will have to bridge our power needs to a fully renewable energy future.

Awesome

Why not use liquid aluminum as a coolant? It melts at 660 degrees C and boils at 2470 degrees C. And it is relatively chemically stable and neutron transparent.

Thnx sir for the video...very informative and nice :) #PHYSICSworldADatabaseofPhysics

I'm still lost on what the bio-fuels are doing here though. Are you using the heat to process the raw biomass to produce fuels?

Pebble one looks like crap...thorium is the only answer: kzfaq.info/get/bejne/q7FjaZqFnM6aio0.html 22:00 - guy forgot to tell, this reactor has a buffer, controll rods inside 24h. Czarnobyl-4 exploded because lack of water, buffer and automatic shut-down system off! P.S. Molten salt thorium reactor can use MANY salts, not only FLiBe! en.wikipedia.org/wiki/Molten_salt_reactor#Fused_salt_selection My faw is NaF-ZrF4 mixture! It looks resilient and cheap! This mixture with thorium fluoride melts in ~400 °C! With no tritium creation! And Hastelloy-N is badass resistant to corriosion!

high temp reactor for hydrogen production

we want a lecture from professor Bonjiorno . if he start the lecture by Bonjiorno, im Frank Bonjiorno

india has built a soduim fast reactor

Pure lead or sodium seem good. All else seem mostly like a hot mess.

pressurised heavy water reactor

The direct manufacture of hydrogen is NOT an immediate goal for these reactors. First and foremost, electricity must be made. It doesn't make sense from a thermodynamic point of view to make hydrogen, if we are still using fossil fuels for electricity and hydrogen production. Please think about this.

Looks like Mark Zuckerberg.

You are not aware of the fact north korea is already in possession of nuclear weapons, are you?

Well, let's hope North Korean don't watch this :)
