This color educational film is about building a compact solution nuclear reactor. Copyright 1955.
Opening titles: Nuclear Reactors for Research (:06-:08). A scientist climbs the steps to a low powered, research reactor. It is used for nuclear research. Geiger counters are used, isotopes are removed. A woman uses a geiger counter. Scientist fills out a sheet on a clipboard. Compact solution type reactor shown via animation. A diagram shows the way the tank is set and how it works. Steel housing is used. The rods are shown in the diagram (:09-2:24). How the mixing chamber and core work. Uranium fission chain reaction is shown and explained via animation. Neutron and Uranium nucleus are shown and explained. Fission process shown and explained via animation (2:25-3:49). Shut down rods are shown and discussed via animation. Ionization chambers. Reactor power level. Layer of lead. Concrete blocks helps with shielding. Overhead view of the reactor shown via animation (3:50-5:02). Overhead view of the reactor explanation. Safety feature provided by a plastic model which shows what would happen if there was a problem and safe shutdown occurs (5:03-6:16). Construction of a nuclear reactor. This is shown and explained in detail. Graphite blocks are lowered inside. In a laboratory, the core is checked and reviewed (6:17-7:25). Scientists turn on a machine. Leak detector. Core in the assembly area. Pipes are installed. Men place pipes into and coming out of the reactor. Gas handling system, flow meters tested. Men hammer a crate (7:26-8:59). Men continue to build around the reactor. Uranium is transferred as a liquid to a plastic bottle. It is poured into a stainless steel mixing chamber. Water is added as well (9:00-10:18). A man connects a hose. A man hands a woman an item. She turns on a machine. She jots down numbers and figures. She uses a ruler. Reactor is ready for operation (10:19-11:37). A man sits in the control room. He presses a button. Power level increases slowly. Rod dial. Counting rate meter. Reactor reaches its operating level (11:38-12:47). Man sits in the control room for the reactor. A rod is inserted into a reactor. Scientists perform tests (12:48-13:36). End credits (13:37-13:49).

Seriously, this had to be the shadiest-looking nuclear reactor I have ever seen. I had never even heard of liquid uranium before either.
This was also the era of above ground nuclear testing. Very entertaining to watch on early morning TV. This ended when they realized all that fallout was ending up in the food supply. Strontium 90 in milk for example. Winds drifted at high altitude from west to east.
As someone born in 1989, I often wonder to what degree cancers are the result of nuclear testing and not lifestyle.
@@futsuu This is something I rarely hear mentioned, but it's a very good point. I often wondered the same thing.
Us GOV responsible for millions of cancer deaths. My own father as well. They’ll never be held to account the bastards.
pretty sure in an alternate timeline, there are small reactors at the home providing both heat and power while emitting as much radiation as a bunch of bananas
This is awesome, I got to use the apple II for training. Nothing like real nuclear decay for training and work.
No mention of the cake of off white color. I came in at the end of the era, heard stories of the tons of "N" stamped welding rod, then a couple decades later watched tons of surplus sold for pennies on the dollar, with certifications. Flag tagged, FTOE FTBO = Flag tag one end - Flag tag both ends - adds an extra $0.15 per lb for 1/8th inch, $0.25 for 3/32, and so on to .023 @ $5.00/lb Then stamped rod came about to save the labor for the pipeline business. San Onofre was a huge end user and as a vendor to several suppliers of theirs I got to participate in the last open house prior to the shut down...the view was incredible.
Every home should have one lol
In case you are wondering, The North American/Atomics International reactor is a aqueous homogeneous reactor. They were very tame and manageable, used widely and one model was sold to Japan for research..
Thanks for the comment. Subscribe!
11:15 it's hard to believe we had nuclear reactors while still dipping a pen in a bottle of ink, I guess the ballpoint pen was cutting edge tech in those days!
Was thinking the same thing
A ball point pen is still cutting edge technology. They are VERY hard to make because of the extremely tight tolerances on the balls and nib.
The first Chinese ball point pens were first manufactured ten years ago.
Y'all dumb as dirt
Not a nuclear engineer, still the overall safety level of this contraption scares the c*ap out of me..
That's where molten salt saves the day. It was available back then, we had a working model that was shut down decades ago at the first power plant.
Aqueous reactors are VERY safe precisely because they are very low powered. A few of the 1950’s reactors are still being used at universities.
This is really good animation
the closed caption has an error in it at around 12:38.
just wanted to let you know.
Thank you for uploading this video I found it very interesting.

So where is the leftover radioactive waste stored?
300psi pressure test using glass equipment and no safety glasses.
th-cam.com/video/PWFF7ecArBk/w-d-xo.html
No gloves, no face shields, no particulate filters, no hearing protection, no spill absorption, no hazmat waste disposal, no radiation exposure badges, I was expecting Tarzan to swing from a tree towards the end...or George of the jungle..."Watch out for that....TREE!"
But plenty of cigarettes
You wouldn’t get me anywhere near one of those reactors.
SL1 told me everything I wanted to know about reactors,and then some.
No animals were harmed in the making of this video, but all the people died of cancer.
@@burtbacarach5034SL-1 taught everyone that a single control rod was a bad idea.
I want one
I want lots of them 😊
Why when it's not your video have you put a huge watermark over it, ruining the video?
Here's the issue: Tens of thousands of films similar to this one have been lost forever -- destroyed -- and many others are at risk. Our company preserves these precious bits of history one film at a time. How do we afford to do that? By selling them as stock footage to documentary filmmakers and broadcasters. If we did not have a counter, we could not afford to post films like these online, and no films would be preserved. It's that simple. So we ask you to bear with the watermark and timecodes.
In the past we tried many different systems including placing our timer at the bottom corner of our videos. What happened? Unscrupulous TH-cam users downloaded our vids, blew them up so the timer was not visible, and re-posted them as their own content! We had to use content control to have the videos removed and shut down these channels. It's hard enough work preserving these films and posting them, without having to spend precious time dealing with policing thievery -- and not what we devoted ourselves to do.

Always find it funny that anyone who espouses nuclear energy as clean and safe never wants to discuss the entirely problematic issue of long term storage and containment of waste, which takes eons to degrade into something "safe". Given that our current storage is consistently leaking, and incredibly toxic and hazardous to deal with, it does not seem as "green" an idea as it's sold to be...
A conventional power plant might produce a few train cars of waste per day, while a nuke plant produces a single cask of spent material over a whole year. A cask is quite resilient to say the least. Certainly well sealed and small enough to be moved with a semi-truck if needed. Or it may be possible to keep the spent casks on site where they can be actively guarded and monitored along with normal plant operations.
@@rentacowisgoogle You can not seal the radioactive waste. I just learnt that Plutonium decays-breaks down to Helium. And you should know what happens to a pressurized vessel.
My god. The radiation exposure to all the people. They really had no idea what hat they where playing with
They did, they just didn't get irradiated like you suggest.
to beginn with, that reactor was designed to steadily run at 100 thermal W of power and due to its autoshut off feature ie
power-excursion -> parts of the uranyl will due to boiling move to another container -> not enough material together in one volume to reach criticality.
suddenly the core is geometrically safe.
