The Ukrainian nuclear reactors are described. This video explains what to worry about, and what not to worry about when a nuclear reactor is in a war zone.
@E Van I think one of the key takeaways is that instead of a graphite moderated reactor that needs the water to keep it in check, these are water moderated reactors that require the water to make fission possible. If the reactor gets hit and the water drains out, what little reaction there is will stop. If the water converts to steam, the reactor will expel it, then dry up and then stop. Thus the reactor won't become a giant self sufficient raging inferno.
Most people aren't very smart, and this isn't a truly simple concept. Fission is complicated, and the Dr. Is explaining is explaining it very well. (but who thinks about heat transfer, fission products, how fuel rods are built, or how reaction containers are fortified.. Or even the mass of depleted fission products and how they are not easily aerosolized? Very few, I assume.)
most people are not smart, without our technology they would still think that the earth is the eye of a turtle and if the turtle shakes its had that causes earthquakes. Dont expect to much from the common fool
I'm afraid there's no such a button. Education is a key here but it is impossible to educate this kind of topics en mass af far as my living experience suggests.
Thank you Prof. Ruzic! I didn't know the plant was made of a set of pressurised water reactors; I thought the reactors were of the old RMBK design. I'm a bit more serene now. It would be nice to see you more often. Regards from the UK, Anthony
I just watched over 2 hours of vids from this channel. Fascinating stuff and extremely well presented. I'm a U of I civil engineering grad so it makes me happy to see a prof of this caliber at my alma mater!
I recently gave a presentation on the "three cookies" quiz. I think I'll link this video to some of my colleagues so they can understand better. Thank you for being a rational mind in the hysteria.
I have really been wondering about the risk of attack and the credence of the nightly news casts that have been freaking me and my kids out. Thank you for this and the calm and logical explanation, it will help me and my kids sleep better.
Thank you so much for this most informative video, Professor! This I can use as a tool to dispel some of the fears of people around me here in Europe. You can explain it much better than I can. As a not-at-all nerdy hobby I study nuclear reactors (with a heavy emphasis on the good old RBMK, though flawed it is in its design), and your videos have taught me so much about the subject of fission/ nuclear reactors. How I wish I would have had the chance to follow even one of your classes. Keep up the good work!
love your lessons' prof, the few real prof's we still have. You also must have been irritated by the nonsense of what politicians say about these power plants.Hope to see more of your video's. Your video's of the past should be obligatory to watch for student one's they go to university there they get thought how to play dames on electric game and standard computers and to write manifests to fight climate change.
I would add that graphite, that was in RBMK reactor, which was secondary moderator that kept reaction going, also is flammable and it's hot ashes became radioactive that spread with wind across long distance - modern reactors not only do not have secondary moderators, they do not have flammable/ash-able components so EVEN in full and total meltdown with uncovered reactor core (which itself is very hard to achieve), hazard zone would be localized, and not widespread.
@@Txmj122 I've watched lectures on youtube. Some of them are pretty good. The information is similar, but the but the production value for this channel is much higher. He's not using the first take. It's one of the reasons I subscribed and hope he posts more often.
That's good to hear. I have degree level physics and have been a proponent of nuclear derived electricity for decades. Nuclear power is deliberately demonised by the 'establishment'.
One thing that needs explanation. Why was the news media making a huge deal about Chernobyl losing offsite power when there shouldn’t be anything to cool there?
You still need electricity to run the ventilation fans. I suppose the 'New Safe Confinement' is held under slightly 'negative' pressure to the surroundings by those fans. This means some air from the inside is drawn out the NSC by fans, filtered and ejected to the outside, while there are other fans to 'push' back air in (but a little less than is drawn out, to maintain the negative pressure). Loss of electrical power to these fans (and al the other systems for conditioning this air, like heating or cooling) wil eventually lead to loss of negative pressure and a chance that some contaminated air could escape.
Very nice professor! I took an energy class from you a couple years back and wondered if the remaining reactors in Ukraine were of the bad Chernobyl design. Thank you for the update!
That was a nice presentation. Simple to understand. I have a B.S. in Nuclear Engineering, U of I, 1981; now pretty much retired. I feel that I got an excellent education there, and I wish you all the success in your career. My career did not go so well, unfortunately, but I had a few psychological "issues" that made it difficult to work with other people (and at times endangered my security clearances), and that was fatal. I had a feeling that my college life would be as good as my life would get, and except for making big bucks for several years, I am now a pensioner waiting for his next check. Sorry to cheer you up so much!
Hey professor! Long time no see! Thanks for explaining that to us! By the way, when will you come back to Brazil so I can be your guide again? Say hello to everyone for me!
When we needed him the most, he came back.
Absolutely.
Tru dat :D

@E Van RBMK is BWR type reactor. Edit: But I ack that RBMK is not commonly categorized as what is known as “BWR.”
Such a shame that the general knowledge of Nuclear reactors/physics is so low. Thanks for getting the word out there professor
the general knowledge of everything is so low how else do you explain getting a corpse elected as president?
recreational nukes for all

if it was more widely understood there would be far less anti-nuclear hysteria, far more nuclear reactors and far lower CO2 emissions.
Oh wow, I wondered if there was going to be another update.
Thanks for hanging in there, Professor.
What button do I push to eliminate the misconception that a nuclear reactor can explode like a nuclear bomb?
I wish I knew......
It's not a button, more like years of dedication to educate the public, excatly what Prof Ruzic doing.
I'm afraid there's no such a button. Education is a key here but it is impossible to educate this kind of topics en mass af far as my living experience suggests.
Easy. Install a nuclear weapon inside every nuclear power plant, thus eliminating the misconception.
what's the difference between a melt-down and explosion? not much.
I've been eagerly awaiting just this kind of video. Thanks for all of your great work!
Thanks!
I've missed your posts and obtaining important information to clearly understand. It'd be great to see more. Thanks Professor!
Glad to see you back emergyprof.
Absolutely.
Thank you!
Thank you Prof. Ruzic!
I didn't know the plant was made of a set of pressurised water reactors; I thought the reactors were of the old RMBK design.
I'm a bit more serene now.
It would be nice to see you more often.
Regards from the UK,
Anthony
Also, RBMK are still operated in Russia...
why you did not google it, if you were not "serene" before? All the info is there, independent of presenters. Get the facts and be serene :)
They're about the same design vintage - VVER type PWRs. Much safer than RBMKs for obvious reasons.

Outstanding presentation at a time when people are worried. Thank you.
Thank you for this concise and on point presentation! Very much appreciated.
Thank you Prof! If only the news could play this video , Useful information would be delivered by them 🤦🏻♂️
I was wondering if you were still doing TH-cam videos, glad to see you are still around
Timely video professor. Great explanation. Awesome learning information. Love the squeaky marker. Cheers man.
Glad to see you back! Commenting for the algorithm!
Always good to see a new video from you, but especially so in these times and on this subject. Thanks for some reassurance.
It was a wonderful surprise to open TH-cam and find a new video from you! Thank you so much!! We have missed you!!!!
Very happy to see Mr EnergyProf back! I always love these videos!!!
Excellent videos, hoping to see more!
Thanks for doing this. I'm a long time watcher of your show, and I used to live in Zaporizhzhia. Thanks for all the amazing content
I recently gave a presentation on the "three cookies" quiz. I think I'll link this video to some of my colleagues so they can understand better. Thank you for being a rational mind in the hysteria.
What I want to know is how he can write backwards so well. That's amazing. Love the videos, glad people are learning about nuclear energy/ physics.
Video is flipped horizontally.
IBM explains its setup for writing backwards in the air! Not very high-tech fortunately. th-cam.com/video/Uoz_osFtw68/w-d-xo.html
A most timely video Professor. Good to see you back.
So good to see you again Professor. Thank you for the informative explanation of Ukraine's reactor designs.
Ty sir. Your lectures are apolitical and informative
Ayyyyyy you’re back 🙏🙌😭😭😭 your videos are so unique, thank you for the information
Thanks Prof. As always, very enlightening.
its about time professor
Absolutely.
Thank you for your informative videos ... I always learn from them.
I always enjoy your content Professor Ruzic. I hope you make more content if/when your busy schedule allows.
Great as always Professor!
Thank you professor for the clarification.
Yes! The war is the issue and risk here. Thank you for emphasising that.
I have really been wondering about the risk of attack and the credence of the nightly news casts that have been freaking me and my kids out. Thank you for this and the calm and logical explanation, it will help me and my kids sleep better.
The media has been scare mongering anything nuclear or radiation related for over a half century now.
dont watch the news especially not with your kids they push a lot of things out of proportion to get view
Glad to see you back again!!!
Awesome to have you back.

Finally you are back professor
Hi, im happy to see you again please upload more videos
I missed you Professor. Really enjoyed this one!
Thanks for the video, Doc.
Thank you for your work, Prof!
Great video, as always Professor 👍
I was missing your videos professor! Don't go away for so long, please!
I look forward to all your videos.
Glad you are back even if just for a one off. I found your videos extremely instructive. Keep that squeaky pen in action.
It's so good to see you after a long long time😊
Great video as usual
I wish videos on this channel were posted more frequently. just about anything he talks about is interesting to hear
He probably spends much much longer preparing a video than the average youtuber. This would explain both the high quality and infrequent posts.
@@nathanbanks2354 considering his job is to give lectures, he already has the material anyway

A voice of reason in the mad world. Thank you sir!
Glad to see more great content from you, sir.
Wooooo Finally! Thank you Prof.😇
thank you. it was a good idea to make this video. we needed to know this.
Good to see you again Prof.
Thank you.
Looks like the radiation has made him become mostly invisible! A few more rads and he will be a superhero!
Ok. Next time it should not be a black sport coat!
Nice video.
I just love these videos.

You are the man!
my favorite prof is back!
great video
My favorite professor, really about to enroll to take your class
He's back!
Welcome back!
Any teacher I had would drop my scores for referring to Wikipedia :D It's so satisfying.
Great video, thank You, please publish stuff more often.
If a F5 tornado is heading your way, a nuclear containment building looks like a good place to hangout 💪
Thanks prof Ruzic love to see more of your lectures.
THE LEGEND IS BACK BABY. Hell yea
glad you are here to speak some sense, despite this paranoia we have around here
Yes!!! He is back!!!
He's BACK!!!!!
The legend returns!
Please do a video or two on the possibilities of closing the fuel cycle--fast reactors, waste burners, CURIO startup planning to recycle used fuel.
Thanks Professor. You were one of the teachers, teaching me how to be the backchannel for the west.
A token of appreciation and respect!:)
Please continue making more new videos.
Been reading the news going, "Somebody get the Illinois signal."
