@whatisnuclear sure, it was a USA design. Just found it funny to hear an english voiceover in a Film about a USA nuclear design not meant for the military that uses metic.
They have found that organics work extremely well for nuclear diven stirling engines. Deuteratated pentane or difluoro ethylene work the best. The core is a ceramic honeycomb and a variable beryllium reflector gives gain. It bumps in pulses like a coffeemaker so each time it gets hot it dumps a puff of gas from the moderation fluid it lowers the reactivity. Posible candidate for space probes that need more power than a RTG can provide.❤
To be fair we've run lots of reactors with liquid metal sodium and NaK coolant as well, which is explosive on contact with water in the presence of oxygen. We can control for this (e.g. by keeping oxygen out).
@@whatisnuclear Yes, I know about those. It just sounds like a bad idea cooling something with low-flash point hydrocarbons. Wonder if they ever tried using Diesel fuel, which is harder to ignite. I mean, it was the 50's and 60's, when every nuclear idea was a good one, right? :)
Honestly I keep expecting to run into an example of a boiling mercury system like they tried on conventional power stations - I mean they had Pluto so why not
Oh goodie! A new historical nuclear gem for us to enjoy. I truly like watching these old research films. But where is that soothing polygonal voice-over from yesteryear? This AI lady doesn't quite have the same charm😅
Wow, where is the English version of this? Thanks for the translation! Would be spectacular to snag the English version of this film as well....I love the original audio in these old films....where are you finding these?
Not sure where the original English soundtrack is. This is just what came out of the National Archives fault of 16mm films. I explain how I get these here: th-cam.com/video/jJ0lxki0a2U/w-d-xo.html
Lots of people thought, and still think, organic fluids may make a good reactor material. Here's a recent publication from MIT: dspace.mit.edu/bitstream/handle/1721.1/117025/1-s2.0-S1738573316300031-main.pdf
I built one. Tiny 1500 kw backyard off grid kinda thing. I had a high pressure high temperature mayonnaise loop feeding the steam generator for the turbine. So anyway it ran great at around 975psi about 550 degree Fahrenheit.
@@sambrose1 where did you source your organic mayonaise? I heard it's important to get good quality. Did you have any problems with mayo fouling in your condenser core fins??
That's just what the film reel they had at the National Archives happened to have I guess. They made these films and gave them as presentations all around the world in different languages. Obviously there was an english soundtrack somewhere as well, but that's not the one I found and digitized.
Lower operating pressure and basically no corrosion is my guess But I'm guessing the byproducts produced in the coolant were nasty to say the least... Also hydrogen and steel bo not play nice at elevated temperature and pressure
It's not AI. It's my friend Shirly who added the english soundtrack. If you check the description you'll see a link to the original audio, which is in spanish, if you prefer!
Is it really though? Worse than pounds per square inch? Sure, I have an intuition as an American about what a PSI is....but if I had been raised and schooled using a saner system like metric it would be equally relatable. At least I know how to convert the metric stuff into other metric measurements by dividng and multiplying by 10....
@@hmbpnz I can do metric, smart-ass. Kg are a unit of mass, not force. Pressure is force/area, not mass/area. The correct metric unit would be Pascals.
@@hmbpnzboth are kind of half good because neither kg nor pounds are force related but mass related units. One should rather use a force there, like newtons
1 kg(f)/cm2 is a mouthful to pronounce but easy to understand: it is approximately the air pressure at sea level. Conveniently, there is a pressure unit for that: 1 atmosphere or 1 bar is approximately 1 kgf/cm2, with an error of about 3%. 1 atm is also approximately 15 pound-force of bald eagle per square inch of of an Olympic-size swimming pool. This imprecision is perfectly acceptable for general discussion when not chasing decimal points. The SI unit of pressure is pascal: 1 Pa is 1 newton of force per 1 meter squared of area. 1 Pa is a rather small unit, so megapascals are often used in plumbing (1 MPa ≈ 10 atm), and hectopascals in weather science where more preceision is needed (1013.25 hPa = 1 atm = 760 mmHg = 29,92 inHg). If you think it’s complicated, look into radiation dosimetry :)
Thanks for translating the original Spanish audio for us, Shirly! Great job.

"and a wall thickness of 2.54 centimeters" sounds suspicially imperial 😂
It was built in imperial, translated to Spanish, and then translated back to English so yeah it was 1"
@whatisnuclear sure, it was a USA design. Just found it funny to hear an english voiceover in a Film about a USA nuclear design not meant for the military that uses metic.
Well, the imperial system is legally pegged to the metric system so i'm not entirely surprised.

Love it. I was just reading about deuterated hydrocarbons in one of the OMRE reports. Probably the most obscure reactor coolant/moderator
I believe that they use the same type of melted cheese that Greggs use in their cheese and onion pasties. About same temperature too.
Has to be the cheese material used in nuked pizza pockets in the US. That gets critical to be sure. 😂
That playing card shirt is incredible.
I noticed that too. So cool!
Hydrocarbons as coolant! I would have never even thought of that. Very interesting, nostalgic video, thank you a lot for archiving these masterpieces.
Nice documentary.
Thank you for this.
It's my pleasure. The best hobby.
