These are really interesting video documentaries. Thank you. 60 years ago ! I can just imagine we will have thermonuclear fusion reactors as common as refrigerators are and just about that size for a complete heating/electrical supply for a large family home using about an ounce of deuterium gas for a months worth !

So the supply of tetralin wasn't being monitored (ie 2 to 10 gal leaked over time). Given the predictable/probable failure of the seal and catastrophic ramification of the reaction seems like an operational/design fault not to keep track of this liquid's consumption.
@@adamjhuber That's absurd - it was an _experimental_ reactor, they _never_ expected it to be perfect. It was built to discover the kinds of difficulties and faults that may emerge whilst operating a reactor of this design type.
@Robert Arnold As an experimental reactor, its job was to ascertain the various faults which could be "predictable/probable" with a commercial, or large scale, implementation of such a design. Perhaps they _were_ monitoring the tetralin consumption but had different ideas about why that amount was being lost, and where it was going (yet another reason for testing design concepts via an _experimental_ reactor). If you were paying attention, you'd realise that the _actual_ error in design, particularly for an experimental setup, was insufficient monitoring of heat distribution (poor layout of thermocouples, insufficient number of thermocouples) and insufficient monitoring of coolant flow for individual channels. Had the excessive heat in the blocked channels been known about, they would have realised that the channels weren't flowing correctly, which, upon investigation, would've lead to the discovery of blockages linked to a tetralin leak. _That_ was the true flaw here - the lack of a precise thermal map of the core - which is unacceptable in an experimental system (that should be gathering as much data as possible).
@@anhedonianepiphany5588 The "true flaw" was building and operating an _experimental_ nuclear reactor in a populous area, _uphill_ from ranches, homes, and a resident camp / retreat, all of which receive contaminated effluent from the SRE site to this day and beyond.
The exploration of all frontiers involves significant risk. The fact that risk exists must never be allowed to curtail such exploration however. It looks like they took the precautions thought reasonable at the time and it is patently unfair for anyone to denigrate these brave men and women for not following standards not known until 50 years into the future. I am thankful for people willing to take these risks so that the rest of us can have the energy we need. Now we need to acelerate the building of new nuke plants.
@Kake Uh, why build reactors that are "nearly impossible to melt down", when you can build reactors that are absolutely impossible to melt down, like molten salt liquid fuel reactors - LFTRs, for example?!? P.S. Yes, I'm aware these have similar fuel processing needs to the reactors you're suggesting.
It was reckless and idiotic to build and operate an experimental nuclear reactor in a populous area, uphill from ranches, homes, and a resident camp / retreat, all of which receive contaminated effluent from the SRE site to this day and beyond.
@@connerstines1578 The point made in my post is valid. If you believe _"morals don't really have that much of place in science,"_ how do you feel about Josef Mengele and others who performed heinous 'experiments' on inmates of concentration camps?

The so called safe dosages that were 'established by the AEC' were largely guesswork and extrapolations - based on what was exigent at the time. Their data came from numerous ethically dubious human experiments on poor, dying cancer patients - and some who it turned out were not actually dying at all! These troubled experimental series were supplemented by extremely intensive post-mortem examinations on the relatively few massive accidental occupational exposures - some mindbogglingly high; 12,000 rads or more. Fortunately though it seems that the linear dose/response assumption was incorrect at the very bottom edge of the scale. There does seem to be a precipitous cut-off point where small levels of radiation do no harm, although the precise safe level varies quite a lot from person to person. This phenomena has been seen extremely clearly in the aftermath of the Chernobyl disaster and is beginning to be seen again around Fukushima. Nonetheless I don't think I would have wanted to be one of those chaps clambering around on top of the biological shield, only protected from the irradiated fuel gases by 1960's polymer technology!!! Not a respirator or clean air supply in sight you will notice. The evolutions where they rotated the entire thing with hand-jacks were especially risky in my opinion. I only hope each and everyone of those poor sods was receiving gratuitously obscene danger-money!!!

This reactor was a useful experiment, the idea used to be to go fast, break things, figure out what went wrong and correct your mistakes. Failure is an excellent teacher. Sodium-cooled reactors are a legit concept and someone needed to make one. The greatest failure was putting it at SSFL instead of BFE Idaho where other test reactors like SL-1were. The consequences of catastrophic failure like a fuel meltdown are substantially less when you aren’t on the edge of a major metropolitan area.
Also, not only has this reactor been decommissioned, the building where it used to be and everything associated with it are gone. It is marked on GoogleMaps as “SRE Experiment”, or something like that. And yes, SSFL is a major polluted site. The SRE wasn’t as bad as the hot cells where they reprocessed spent fuel.
@@Duvallmd what do you think they did with the sodium that was in the reactor. It was burned in an open pit at the ssfl. It hasn't left or been cleaned up.
darryl haynes I’m not a nuclear physicist, but sodium is a pretty inert substance from a radioactivity standpoint. According to Wikipedia the only stable isotope is Sodium-23, and if it absorbs a neutron it becomes sodium-24, which decays to a stable magnesium-24 with a 15 hour half-life. In short, 150 hours after you turn off the reactor (10 half-lives), you are back to a non-radioactive material. Now, the meltdown and whatever leaked out of the fuel will still be a contaminant unless they filter/absorb it out of the sodium. Sodium is more reactive than toxic, we have sodium salts on our dinner table.
More and more energy to make more and more crap we don't need to make more and more money that doesn't exist to further enrich a handful of people who could never spend what they already have. Welcome to the American dream.

@@christopherwojtan750 I agree and that's exactly why we need to leave this technology alone. Humans are always going to be humans, so that's not going to change. And if these reactors are state of the art, then nothing to change there. So, if we go forward, we go forward with the same flawed scenario. The cost to our planet is just to great everytime one of these melts down. Then there's the fact that in every one of these meltdowns, the actual meltdown is just the beginning of human error that occurs. It continues to compound exponentially with the lies, the cover ups, and the expanding, extended exposure of the environment and the population to deadly radioactive elements all while those responsible are busy passing the buck and covering their own asses. Case in point, I just became aware of the SSFL SRE Meltdown in 1959. As if a meltdown isn't bad enough, that wasn't the only "accident" they had, just the biggest one we've found out about. Additionally, they tested rocket engines there that they would rinse down with the most toxic substances and just let it run into the dirt. Did I mention how they handled the barrels of radioactive sodium ? They'd put it in a little row boat, then launch that into an open air pond and shoot holes into it, causing the Na+ & H2O to come into contact, therefore violently explode- sending radioactive material into the open air! My parents grew up in Canoga Park, I was born in Canoga Park and grew up in the Valley, my kids grew up in the Valley. And we never knew, those fuckers! We never knew! IT'S STILL NOT CLEANED UP. IT CONTINUES TO LEACH RADIATION AND JET FUEL INTO THE GROUND WATER! Humans can't be trusted to play God, they've proven that everytime the opportunity presents itself.
And that is blatantly false. Most reactors built have had long service lives with no meltdown or other form of failure that would pose a safety risk to the public or reactor crew. It's a shame how these videos attract such ignorant people.
@@angeliquerider-mitchell2538 The fact you're saying we should "leave the technology alone" despite the fact it is one of the statistically cleanest and safest forms of power production available and has also provided the medical field with multiple forms of treatments for cancers just shows how ignorant and backwards you are.
@@angeliquerider-mitchell2538 You mean the US should leave this technology alone. You also have to remember the distinction between experimental and commercial reactors; and there's also the historical, geographical and political context to consider. SSFL is a radioactive bin fire, and was THE "Wild West" of Cold War technology, but anti-communist paranoia has more to do with that unforgivable neglect than nuclear science. Only one commercial reactor has has a "meltdown"; the No 4 unit of VI Lenin NPP in Ukrainian SSR in 1986.
Dislike What a bullshit and wasting of time. For me coolant should be: - safe to touch - inert (no air/water reaction) - inert in higher temperature (800°C) - stable (do not decompose) and liquid even overheated (1000+ °C) - do NOT react with fuel, water, air and contruction material, even overheated Sodium pass?
This is an LMFBR (Liquid Metal Fast Breeder Reactor), where the coolant is liquid sodium.
