You're a nuclear physicist who reacts to online videos. In a way, you might call yourself a "nuclear reactor"

It's awesome to see Kurtzgezagt getting fact checked, and even agreed with!

Our world needs more experts explaining things in clear ways that a layperson can easily understand. Thanks for your hard work.

Kurzgesagt puts in the work to produce their videos. They have a whole video explaining their process and how a video is made. They spend a lot of time and energy making sure they get it right. (sometimes they even correct themselves when they get something wrong!) One of the best channels on youtube.

Hey guys, in the video I made a mistake referring to 70% of energy in France being generated by nuclear. The correct statement is that 70% of electricity in France is produced by nuclear. Thanks for pointing it out and enjoy watching ☢️👩🏽‍🔬

Kurzgezagt is one of the most accurate, thoroughly researched and serious channels currently on KZfaq, so I'm glad to see that you agree with this video after hearing your regular "true", "that's accurate", "exactly", "precisely", etc. and just adding extra info that the original video didn't have time to address in detail. Thanks!

I LOVE Kurzgesagt and all their videos! So I’m really pleased to see an expert fact-checking them!! Thanks for this! :)

As a person from Finland, the slow building of nuclear plant is definitely an issue. Finland was one of he few western european countries that has built a new nuclear plant (it is built by Areva and Siemens). The permission for it was granted in 2002 and building started in 2005. It was supposed to be finished in 2009 but has been delayed multiple times for multiple reasons. At the end of 2021 it was finally started for first time for testing and in September the first full power tests were done. It is slated to be in full production in December this year. So a very long project indeed.

I watch their videos regularly, and they are very good. These videos proves you can educate without indoctrination someone to a cause. I've always found them to be very balanced, and show information from both sides and allow the viewer to form their own opinions.

2:40 This point about france is really important I feel. They produce most of their power from nuclear, and they've never had a significant incident. France proves that nuclear power can be done right, but a couple of poor governments make some bad decisions and/or leave their reactors in the hands of undertrained staff and everyone goes up in arms against the technology instead of the people. A factory can poison the waters around it for miles (depending on the factory of course). Does that mean we should stop building factories? No, it means we should carry out careful waste management procedures within and around factories. It's a problem of management, not of the technology itself. And France has the management 'problem' solved. Other countries should follow their example.

I love seeing videos like this as a huge nuclear energy advocate and a student studying nuclear physics there are so many misconceptions about nuclear power and its safety and the possibilities of the future advantages of nuclear power

Seeing a Nuclear Physicist fact check a Kurzgesagt video is something I DID NOT know I needed in my life until now

Yes! Finally! People need to move past the false dichotomy created by political and economic interests and I'm glad to see the increasing amount of expert coverage of such an important and nuanced topic.

Let me know how you liked this reaction video and thanks for suggesting it guys! It was really fun reacting to it! ☢️👩🏽‍🔬 stay tuned for next weeks controversial episode!

I love Kursgesagt and always recommend it to my friends, it’s always very didactic, clear and makes a lot of effort to be as accurate as possible for 10 min videos

This was fascinating! I frequently enjoy Kurzgesagt so it was reassuring to hear an expert largely verify what they said. There was another video released just recently by them to do with nuclear waste disposal, that would also be interesting to hear your thoughts about!

As a mechanical engineer, I appreciate your passion and frustration for this topic. I believe that you are correct, it will take a long fight to do the right thing and I’m glad that you are on the correct side. Keep going, I will keep fighting too.

Glad to see Kurzgesagt getting recognition. Loved the video. You got a new subscriber!

This is how reaction videos should be made, love how you transition and that picture in picture view is perfect, good job.

I'm a big fan of Kurzgesact, I'm now a new fan of yours. It's always awesome having a source you trust being checked by an expert. Thank you very much for your video.

I love academics getting into the youtube space to factcheck videos. Misinformation or misleading information is rampant, and you're doing the best science communication work possible in my opinion. Cheers

Hey! Kurzgesagt viewer here and I appreciate you taking the time to run through one of their videos. I generally hold them in high regard for their quality research and it's really nice to see that confirmed by other sources. Now I get to binge on your other videos :D Secondarily, I am 100% in the more nuclear camp and I appreciate anyone in the field trying to make workable solutions.

Thanks for confirming that this youtube video is of high quality to understand the issue at hand. In this age of information, it is always a hard task to find quality information and not get lost in the junk of Internet.

It's unfortunate that fusion always seems to be "20 years away." I'd like to think that, with the recent successes in testing fusion, we're actually closer to truly being 20 years away than ever before. Perhaps you could cover some of these recent tests and give your opinion on how close we actually are to the final breakthrough necessary to make fusion a reality.

I found myself applauding through the video. We need more of this, for the future of energy, of food, of everything. We need to make decisions based on the best evidence available. Governments need to start employing actual scientists and specialists to inform policies. Thanks for clarifying every point, and kudos from the land that houses the old Atucha I (didn't know it was THAT old until now).

It is perhaps the chief saving grace of humanity, that people feel the NEED to explain things they understand to others, its almost like a biological urge to share knowledge and its amazing. Love this

I am an avid Kurzgesagt follower and saw this video in recommended list... Kurzgesagt screenshot in the thumbnail caught my eye. I like how you went through the video, and I subscribed immediately, and watched your other videos as well! I hope to see more reactions to tv shows like Chernobyl in future, the Simpsons are also funny and fun :D I hope you will help the internet auditorium to better understand nuclear energy, debunking all the horror misconceptions around it etc. I wish you many many more subscribers soon! Keep on the good work!

Great reaction! After high school physics, I never understood why people were so strongly against nuclear when the alternatives (fossils) are so much worse. I think it's largely an education problem.

I always fear nuclear brca iam Ukrainian but i am learning more and more and its so interesting how fear makes one ignorant ♡ thank you i am learning so muchhh

Just found your channel and really love your content, thankyou for doing what you do. I wirk in the environmental industry here in Australia and i regularly have discussions with colleagues regarding our challenges with energy in the not so distant future. It always fascinates me that the major of my peers either don't know or don't understand that 'long term energy storage' is one of our biggest problems. Particularly in a country as vast as Australia. I mean 80% of Australia is still without telecommunications coverage. The idea that we will somehow be able to capture, store and supply clean energy throughout this country is a fantasy. Necessity is the mother of invention. Hopefully it won't be desperation. 👍

A huge issue with electrifying everything is that our current power grids also don't support it, in my country alone power grids were overloaded during the summer due to almost every house having solar panels, a heat pump and many people cooking with induction and driving electric cars. It was so bad that power companies blocked generated power from solar panels outright. If we want to electrify the world we don't just need better sources, we also need better transmission. The world's power grid needs a massive upgrade.

Very interesting and I agree a mixture of renewables and nuclear has to be the way forward for the time being at least. Sadly, here in the UK, there has been as much opposition to some renewable projects as there has been to an increase of nuclear by the very groups who are opposed to fossil fuels, the Severn Barrage tidal project springs immediately to mind. All parties are going to have to accept that there's always some price to pay.

I just found your channel today (courtesy of KZfaq recommending your reaction to Kyle's half-life files) and I have been binging you since. Kyle was actually the person that originally changed my mind about nuclear power. Since he left because science and started his own thing, I've been finding myself desperate to learn more about nuclear energy. I'm not a hippy. But I do love the environment that I live in. We need to change. We need to be better. -Kratos, ghost of Sparta

Good too see actual intelligent information being presented about this problem

I love those videos!! You offer a different non biased view to an already great informal video! It gives us, non expert viewers, a great perspective on nuclear energy!

The biggest issues I see in a country with zero nuclear (Australia), are that; 1. The time for a FoaK (First of a Kind) nuclear power station in Australia will be over 10 years, probably longer judging on how we deliver major infrastructure projects. In that 10+ years, we could instead install plenty of wind, solar, hydro, BESS (battery storage) that would not only exceed the GW capacity of a future nuclear power station, it'd be deployed over that decade and force FF plants offline sooner, yielding 'green energy' well before the nuclear power station is commissioned. 2. We have plenty of wind/solar resource and plenty of land. Therefore we can (and are) quite easily deploying a lot of wind/solar in the country. 3. The NEM (electricity grid on the East coast) stretches 5,000km (North-South). If it's not windy in one location, it's windy in other. Due to such large geographical spread, aside from solar, the weather does change significantly. We've also plenty of mountain ranges for PHES (pumped hydro). Essentially we can over-install the GW we need of generation such that the maximum demand is always met by minimum generation. Again, we can continue to deploy this now, while FF power stations are retiring and over 10 years before any nuclear plant would be commissioned. 4. Lack of social licence. Pro-nuclear is a very tiny minority in Australia. It will take many many years to sway the majority opinion in order to gain social licence to commence a nuclear program. Then tack on 10+ years to design and build it. Without social licence, you won't get it off the ground as no government would overturn the current ban in place on nuclear power. 5. Nuclear power has been investigated and is simply not cheap enough compared to wind, solar, hydro (PHES) and even firmed with storage. Solar thermal can provide time-shifted generation to meet demand peaks (e.g. evening peak) and is forecast to be way cheaper than nuclear in 2030 (for Australia). e.g. This report with cost analysis on generation technologies: publications.csiro.au/publications/publication/PIcsiro:EP2021-3374 6. The move to distributed renewable generation (wind, solar, hydro) are generally individually smaller power stations compared to old coal and nuclear power stations. This is a benefit in that if any one power station goes offline, it has less of an impact on the overall generation supply. 7. The disadvantage of wind, solar PV and similar technology is that they're asynchronous/inverter based. They inherently make the electrical grid weaker due to it's old design. However new BESS technology, synchronous condensers and steam-turbines from hydro/solar thermal are available to help strengthen the grid as a counter to the asynchronous tech. I can see many other non-nuclear countries would be similar, specifically the 10+ years to get the first nuclear power station commissioned. So even if you discount the issues of nuclear waste, radiation leaks, melt downs, etc... I still can't see it stack up unless you've got a well established nuclear power industry. Otherwise they take too long to commission (FoaK), they likely have no social licence (which takes time to change) and are much more expensive than many other technologies being deployed.

Great video! I love Kurzgesagt and I know id really love to see you react to the other Nuclear related videos that they produce!

Came here looking for scientifical criticism, instead I only got deeper into my confirmation bias ;) but seriously, great work at spreading knowledge in very understandable form, content creators like you makes hard and complicated topics a little more easy to get grip on :)

Great Video. I've been watching Kurzgesagt for years and yours for several months so it is great to see your opinion on one of their vids. I live in California, a state within the US. We need power and water. So I would love if they started bringing more nuclear power plants online combined with water desalination plants since they can work together. I doubt it will happen here yet it would be nice.

I've seen a lot of videos that deal with the subject of energy (nuclear vs fossil energy vs renewable energy) and it only very rarely talks about mining (how it is more and more complicated to extracting the minerals, how much it destroys the environment, the geopolitics around it). I think it's a key point

I liked that you're mentioned that each region is going have a type of energy generation that is better for it, for example Brazil, were I live, is full of rivers with a ton of waterfalls so most of our energy comes from hydro

Thank you for taking the time to review this video.

Here in Georgia (the US state, not the country), we are trying to expand an existing nuclear plant from 2 reactors to 4 and actual construction on the expansion has been going on for 13 years now. It's been a year or two away from completion for 5 or 6 years now... And that's just actual construction - the planning took I believe 3 years as well. And that's just expanding an existing plant, not even trying to build a new one from scratch. "A decade or more" - a LOT more... We needed to have been building nuclear plants starting 20 years ago.

Love the video (both)! What I do have a huge issue with is their categorisation of burning of Biomass as a low emission powersource. There are plenty of sources that show chopping down trees to make pellets to fuel biomass powerplants. Per definition you can categorise wood as a renewable powersource, that doesn't make it a good thing

I recognised the channel straight away from your thumbnail and gave this a watch. And you're right, "their name" is pretty hard to pronounce, even harder to type. 🤣 Good video I love your accent. ⚛️

Kurzgesagt means "In short", and i folow them, they have an incredibly good channel with lots of information and simplicity in their explanations very accessible to all people, that would be of great use in schools to any teacher in any science areas.

great video, some people fear what they are told to fear, US media has done a great job only showing the scary parts on Nuclear power. I believe I read some where that more people have died just digging up coil than all Nuclear power death combine. thank you for sharing

Technically, nothing is renewable. Lithium for batteries is not renewable (and its mining is devastating for the local environment), silicone is non-renewable, etc. Right now we need clean energy, not renewable. Looking forward to seeing the implementation of Small Modular Reactors; their by-product is hydrogen, which can be used in the aviation and automobile industry.

I just landed in the right side of KZfaq, it was amazing to hear an expert's opinion over a channel like this. Thank you!

i didn´t know that kurzgesagt does translate their videos into english. As a german who only saw their videos in german I was kinda nervous at the beginning because I thought the video would be in german with youtube subs which aren´t 100% accurate but to my pleasent suprise they also have an english channel which I love because the videos are really well made in my opinion. Happy to see that you think so aswell

Finally someone else who understands there are pros and cons to almost anything! 15:00 One of my people!... I feel like there should be more of us but people do really seem to enjoy black and white answers rather than swimming in the grey areas

The best video I've ever seen about this topic is the one from Simon Clark called "Why nuclear power will (and won't) stop climate change". It's 40 minutes long, and it goes more in depth than this already very good Kurzgesagt video, and has also more relevant points. The video might be too long for a reaction as a whole, but maybe you could watch it and in your video only react to certain parts of it.

Thank you for this video! You explained things so amazingly well and I hope you could react to more from Kurzgesagt! (Or just say "in a nutshell" because that's the translation of the would kurzgesagt)

Kurzgesagt is one of the best science channels out there.

I got an ad for the American Nuclear Society under this video, I didn’t realize they did advertising. I would also suggest an episode of “Half life history” from the KZfaq channel Kyle Hill as a video to react to. I’m currently an undergraduate in nuclear engineering and I’m happy to find a nuclear science focused channel since they are kind of rare!

I didn't check through all comments but there is a little mistake at the beginning, in France 70% of electricity is comming from nucelar not 70% of the whole energy. Anyway it is a great video thanks

Hi it's my first time watching your channel and it's really nice to have an external opinion on Kurzgesagt. I have been watching their videos for a long time and they honestly always give a really good broad opinion so I would definetly encourage you to do others topics on their work ! Thanks for the really good quality insight ^^

Do you have any reference mentioning that the reserves of uranium would indeed last for so long? I tried looking this up online, but didn't come up with similar values. Thanks :)

Great video, i honestly appreciate a more "serious" and in depth approach like this video (by the way i highly suggest all kurzgezard video, for the high value in accuracy and accessibility). Maybe you could give an opinion about Scott manley "Going Nuclear" series or a single video from it, i would sincerely appreciate

I have always believed that Nuclear energy has great potential and it can in a way satisfy global energy demand as well and it is as safe as any other energy provided all the safety protocols and measures are properly followed and implemented. I think the biggest hurdle in realising it's full potential is misconceptions in the minds of people around nuclear energy and i feel extremely proud that peoples like ELINA madam are doing their part in eliminating misconceptions around nuclear energy. So thank u madam🙏🙏🙏

Love this! Hey…real quick, what’s the brand and model of the LAV microphone you’re using? Thanks in advance!

I'm very glad you did react at one of Kurzgesagt videos, I'm not expert. But I always watch they videos and it looks like they do a good research, and try to be unbiased. Also I'm very glad to find your channel :), as a curious mind Is always nice to find people that know their stuff to give some information. Thanks for the Videos.

Another reason why I wanted to hear your opinion on Season 1 Episode 14 of Captain Planet and the Planeteers, is because I'd like to hear what you have to say about the anti-nuclear power messages and how much of their lessons did they get right and wrong? It's even an episode with their radiation themed supervillain.

Kurzgesagt is awesome and also illustrates (for a big part) the power of publicly funded media.

I read in a scientific magazine (no not a peer reviewed journal) that interviewed a group of scientists who were doing a study on radiation from power plants. What stuck with me was that coal power plants actually produced measurements from the outside of the power plant more radiation (I don't know if there is different types of radiation and the interview never asked) than those in similar locations of nuclear power plants. The article was written with trying to make the readers be shocked and maybe a little afraid of coal power plants. It always amazed me that we don't know that nuclear power plants because they deal with radioactive materials try to prevent radiation leaking. Which would mean that they would build to protect radiation from affecting the outside environment as much as possible. Which would mean that you would get less radiation from the building outside.

Just loved the way you reacted on it providing us more details of it❤🎉

I think there is one thing that is represented wrong in this video. Nuclear requires a lot more backup power than solar and wind. What most people forget: Nuclear fission (or fusion) doesn't turn turbines. Steam turns turbines (and generators). For that you need to take water from rivers and heat it (and then put it back) which heats the rivers. There is only so much heating you can do before you kill all life in a river (due to lower oxygen solubilty of warm water). For this reason powerplants in France have already had to shut down in the summer months (and powerplants in germany have had to curtail power output) With climate change (i.e. warmer rivers and rivers that have less water flowing in them) this issue will worsen every year. So while you need a few days worth of backup (storage) for solar and wind you may need MONTHS worth of backup storage for nuclear in the summer. (Dry cooling lowers efficiency, i.e. ups the price of power and using seawater is not an option as it lets maintenance costs go through the roof increasing the price of power enormously) The need for so much backup makes nuclear incredibly expensive...aside from the fact that it's already the most expensive form of energy production...and let's not get into the costs of waste management, decomissioning or lack of insurance for nuclear powerplant. If one were to add these costs then the cost of power from such powerplants would be astronomical. Currently these costs are just hidden in the taxburden of taxpayers.

Quick note: Kurzgesagt is produced by the german public television. Its not a single person making these videos, and they put out an entire video explaining their process ("Can you trust kurzgesagt?" on youtube). Good video tho!

Thoughts on Nuclear Fusion? Great video tho! Just found your channel and definitely sticking around :D

Good to know, especially since I already used that video to educate my daughter about this topic a few years back. I'm glad I picked a good one.

Can we get your input on the actual damage from Fukushima? I would like to think that the level of containment that occurred from that disaster tells more of a success to nuclear power than dangers. I watched Three Mile Island docu-series on Netflix, however, and it painted a truly ugly and grim picture of nuclear power…something I have been inclined to support more than oppose. I love your videos, btw!😁😁😁

Wow, an English speaking high-quality video by a Greek. I'm very impressed. Bravo!

Thank you for providing your professional expertise! Very informative. Also, completely unrelated but as someone who grew their hair out during quarantine, yours is beautiful and I'm super jealous of it lol

Tremendous video. Well done. I do think that fusion power will ultimately be the next major source of energy, but we have some serious hurdles to overcome. ITER and DEMO should help with that, but the time horizon just doesn't really mesh well with the emergency that is climate change. I agree with the video you are reacting to (and of course your comments) that renewables and nuclear (which, although not "renewable" is very sustainable over long time scales) need to be pursued as complementary to each other as we desperately search for solutions to our ever-increasing energy needs. I hope to see more of your videos and will subscribe and look at anything else you may have posted. This is the first video of yours I've seen. I hope you do more than reacts. A nuclear physicist on KZfaq? I can't wait to see what you can teach those not in the know :)

Love nuclear! We are fully electric (except water heater) with solar and batteries on the house. Now we only import some of our electricity from November - March, and I'm sick of it being coal generated! One point about EV charging demand on grid, if regulations and manufactures take a couple steps in the right direction, we could use car batteries to balance demand for grid. We've learned that house electricity usage is much less than what is required to move a car from stopped position. It's a shame those big battery packs just sit idle when they could be used to reduce peak.

I noticed how you did not touch the fact that production and recycling of solar panels/batterys is extremely polluting and has allot of toxic waste that stays dangerous for millions of years instead of 10000 for nuclear waste. Polititians blatantly ignore this

From the thumbnail I thought you were against that video (that I watched when it was released).. As a fan of Kurzgesagt it was a good opportunity to confront their views with someone unbiased, glad to see confirmation of that info! Btw, they always share ALL the sources they use, both as a note in the bottom right during the video, but also as a document linked in their description

"Nothing is quite perfect, but at the same time nothing is useless" when it comes to energy production. Imma steal that quote and use it all the time.

Kurzgesagt is one of the very best KZfaq channels out there for science/education content. It's German, it's pronounced Kurz-guh-zat (more of less), and means 'in a nutshell' which is a great name for the channel. Highly recommend their immune system series, as you'll already be familiar with most of their other general science content.

Off course they are accurate. It's Kurzegesagt ! One of the best educational channel on KZfaq :)

Great video! Just found your channel, subscribed ;)

Great reaction video. I really enjoy your work. 😀

It's a fact that each energy source has its own pros and cons. What I wish is that the land use would be highlighted more for most renewables. The amount of land required to scale wind, solar and hydro to our current requirements much less for the future needs is immense. But that is rarely, if ever, mentioned. Great job!

Could you do a video on Natural Nuclear fission reactors? Just found out that apparently even nuclear power can occur in nature on Earth.

Have you guys seen the storage for nuclear waste products? Those things aren’t getting cracked open by anything. The fact that most people don’t know how this stuff must be stored really calls into question their education on nuclear energy.

Lots of love ❤️❤️❤️❤️ we huge number of real science people to communicate real science with humanity, great to have you Elina ❤️❤️❤️❤️ From Haryana, India

Too much over engineering to make it safe means too much money and time wasted... Keep your eye on the ball people ...we don't have that luxury. If is not cost effective and it won't make a difference in the next 20 years.. the market won't let it happen... No need for regulations or histeria. Simply put... _Not the path of less resistance_ .. therefore not something that will succeed .. Natures wisdom is to be heeded 🙄🤔👁️🤔🙄

It's nice to see Greek content creators create quality content on this platform.

I find the Kurzgesagt videos very fair minded. Nice to see your informed analysis, especially given the level of confirmation for my own views of how nuclear is an essential COMPONENT of a clean energy future. The promising new 4th gen reactor designs need serious fast track investment, especially given the time pressures of "no return" tipping points Eg: LFTR reactors are going online in China this month.

For example here in Finland, solar, wind and hydro are not really that reliable. Only energy productions that work here 24/7 are fossils and nuclear.

Basically everything I've been saying for well over a decade

A friend of mine stated that a problem a lot of people don't adress, is the fact that powerplant use a lot of water and it's starting to be rare as well. And to him that's why nuclear is starting to get problematic. What do you think of it ? (I'm honestly curious)

Μπράβο, πολύ ωραίο βίντεο και πολύ καλές επεξηγήσεις. Το αγαπάω το κουργκεζαγκτ, και μου άρεσε που μου πρότεινε το βίντεό σου. Χρειαζόμαστε να ακούγονται περισσότερες απόψεις από τους ειδικούς του κάθε πεδίου. Μίλα περισσότερο! Ευχαριστούμε!

I am at a point in my life where money isn't exacly in abundance but I donate what I can to Kurzgesagt each month for exacly this reason. I believe they are doing a great thing sharing information to the world the way they are and its always validating to see a professional in the field comment good things about them.

Good to see a someone with a background like yourself reacting in a neutral objective way. The only thing i would add is that (at least right now) battery form of energy storage is very poluting for the environment. As well as this technology is neither renewable nor sustainable (at this time), although efficiënt if you look at short time frames. Great video :)

It has worked in France for decades. It’s a solved problem.

Kurzgesagt (KURTZ-giz-aget) A smart series of workers who made me pass my astronomy class

Very nice video! I would expect more technical explanations by the title of the video but overall chill and positive vibes. A bit weird though you didn't already know Kurzgesagt!
