The way you talk about these topics is so pleasurable to listen to, and the topics are actually something I'm interested in and kinda related to the game. Good Work Man! xD
You can always look into better cooling - especially stock CPU cooling can be kind of bad compared to what you can get for not a lot of money. Kind of a bother with cleaning up and applying thermal paste and making sure it's working properly though.

The reactor accident you referenced, SL-1, had two other fatalities in addition to the harpooned guy. It was the central (most reactive) rod that was pulled out upwards of 10 or 15 inches beyond the three that was allowed chernobyl is another well know prompt critical event
Being in one piece a minute later isn't so hard... the tricky part is in ensuring that the "one piece" is still above ground level (as opposed to having "negative altitude") and possesses some measure of depth in the "Z" dimension (as opposed to being spread very thinly over a wide area).
Great story about the criticality accident impaling that poor guy. When you started saying you had a story about it, I thought you were gonna go into the accident with the so-called tickling the dragon's tail experiment. I'm really glad you talked about something I hadn't heard of before.
Yeah there were a couple different ways I knew of. One was manipulating the locations of planets so that they were very close together using the Kopernicus mod.
Yes! It's even a semi-valid technique especially when using ion engines (or electric engines from mods) and need to get to a distant planet from a mod. The swingby not only gives a useful amount of oberth effect but all the solar energy you could ever want.
FYI on the SL-1 story that Scott talked about: SL-1 was a 3 megawatt US Army test reactor. Apparently during testing, one of the control rods had been sticking so a tech yanked on it to try to free it up a bit. It became unstuck and was subsequently pulled out too far, causing the instantaneous reaction. When it went prompt critical, it generated 20 Gigawatts of power in 4 thousandths of a second. This had the effect of vaporizing all the internal nuclear material and moderating water instantly and sent the entire reactor (20,000 lbs / ~10,000kg) upwards at 27' per second and blowing the top of the reactor off. The supervisor was pinned to the ceiling (as Scott mentioned) with a control rod and another was also found dead when the firemen arrived in response to a fire alarm. One man survived for a short time, but passed away shortly after being rescued. The combination of radiation exposure, blunt force trauma, and being heavily scalded by steam meant he had no chance for recovery. When the investigation started, they knew if was a prompt critical incident by looking at one of the guys gold watch: a significant amount of the metal had been turned to a radioactive gold isotope. More information on the SL-1 reactor incident can be found online (like here: digital.library.unt.edu/ark:/67531/metadc1053436/m1/1/ ).
Scott - I've been studying nuclear engineering since Fukushima, and am very familiar with the various stories of criticality incidents, but I'd never heard the reason why a blue flash was seen. Thanks!
Full disclosure - I'm not in a program, I've just been self-studying. That said, I'd start with the following textbooks if you want to get a jump on formalizing your education: "Nuclear Reactor Analysis", Dunderstad/Hamilton, "Fundamentals of Nuclear Science and Engineering", Shultis/Faw for basic processes. "Measure and Detection of Radiation", Tsoulfanidis/Landsberger, give you a focused background on, er, detection and measurement. Lay books that give a bunch of background: "Atomic Awakenings" and "Atomic Accidents" by James Mahaffey gives good history and accidents - they're both very accessible books, and the author is a knowledgable practitioner. "Nuclear Energy: What Everyone Needs to Know", by Charles Ferguson, gives a very concise history of things like the Uranium fuel cycle and general reactor technology, but at a very high level (it's a short book and gets to the point, but it's a book of breadth more than depth).
Heat is why I have an AC in my room year round. Even in the Minnesota winters. Although I do turn the compressor off and just run the fan. For some reason I get the hottest room in every house I have lived in, faces the sun all day, top floor, all the vents just dump into it.
Yeah, the SL-1 reactor incident was sketchy asf. Like the guy hanging from the ceiling for about a week and a 130 degree room, not rotting because he had been sterilized by the radiation.
Shake n Blake l January 3, 1961. It's unknown what killed him first. I like to think that the massive pressure wave it created from all the water flashing to steam and shooting the control rod out knocked him unconscious before he felt anything else. But there's no way to know. It's because of that incident, that all reactors built in America or any similar designs across the world are designed so that even if the most reactive rod in the core (the rod with the most unburned fuel in proximity) is pulled entirely out of the core, it won't go critical. Prompt or otherwise.
Putting the separators near the top... In 2 years of playing KSP, why didn't I think of that? I once did surface to low Mun orbit in 10 minutes, but that was with KAL overclocking an ion engine with a minimalist craft. When I made a good, alien-looking ship out of silver fairings and Mk1 inline cockpits with only the bubbles showing (and lit), the overclocked ion engine would break free and tear through the rest of the 12-ton ship if I gave it more than about 1/3 throttle.
I saw the blue on small research reactor on a school field trip,the army reactor you talked about has a youtube video,I served in the USN subs our nuke tpes look down om the army types and us army got out of the reactor biz after the 60's.
You know it's gonna be a good KSP video when Scott is saying "Oh good! It didn't explode!" Inside of 40 seconds into the video. XD (Okay - to be fair - ALL of Scott Manley's KSP videos are awesome. But hey... :D )
Doh. Was wondering about the strange triangular ship you can see against the sun at about 5min. Aliens in Kerbal alert! Took me another 5 mins to realise it was the cursor.
And different materials have different delay neutron amounts, which is why some of us have concerns with different fuel cycles...ala thorium/u233 has about half as many delay neutrons as U235. This can result in stability issues depending on the design. Particularly for MSR promoters, we will have to REALLY make sure we do the CFD right or risk Doppler expansion oscillations (POGO problems!)
I have also read that, in a MSR where fuel is pumped, the delayed neutrons will be produced outside the reactor. The Molten salt reactor must be designed for prompt neutrons similar to a fast spectrum reactor. In a fast spectrum reactor, the fissile material density and neuron population density is so high that the delayed neutrons do not play a significant role in controlling the reactor. Some designs like static salt reactor (Moltex design) avoid this problem. These reactors do not pump the liquid salt out of the reactor core.
No typical reactor is designed for prompt critical neutrons. In a prompt situation, fast reactor power would increase by e every 0.1 ms (or 22,000xish per ms). Delay neutrons play a role in fast reactors as well, it is what allows us to control them along with other feedbacks. The difference is the mean neutron lifetime is much shorter in fast reactors so power spikes can happen at a rate an ordered of magnitude faster in a fast reactor, so important care is taken to sometimes soften the spectrum, space the fuel different, have differing enrichment profiles in fuel elements and rod spacing, ect. We won't fix MSR by designing them like we do solid fueled fast reactors, they are using an entirely different tool set as many fast reactors are heterogeneous in nature.
Delayed neutrons are important when power levels rise. Different reactors use different methods to increase power level during startup, CANDUs use gradual addition of moderator (heavy water) in the calandria tank and control rod action. I think in the MSR, they may use the method of adding fuel salt slowly to increase the power with the action of control rods. Also in transatomic power design the moderator moves. They may use the method of adding more moderator into the reactor core to achieve this? In the article "MOLTEN SALT REACTORS - SAFETY OPTIONS GALORE", Uri Gat writes "Early concerns of loss of delayed neutrons, which are carried out of the core in external cooling, turned out to be of no significance." But, he does not discuss anything how they solved this problem in 7.5 MW MSRE. He writes about continuous removal of poisons and online refueling aids to run the MSR with low excess reactivity. Is this the reason the loss of delayed neutrons was not a safety concern in MSRE?
Because it depends on a bunch of different factors. They weren't doing any helium sparging like some reactor types want to do. Also, size of the reactor matters as the larger you get, the less leakage you get axially. Also the hotter the central axis gets which affects your Dopplar expansion and nuclear resonance for absorption (particularly important for denatured reactors with lots of u238). Basically, like all reactors it takes some engineering and this is one of those things that has to be properly modeled to avoid problems, just like everything else. There is no inherently safe reactor, safe is a matter of design choices is my point.
Doppler expansion and resonance absorption by U238 or Th232 is beneficial. It is responsible for negative temperature coefficients of reactivity. Denatured reactors have strong negative coefficients and it is a good fuel choice. I agree your point that inherent safety is result of various design choices like the use of inherently safe coolants, fuels, fuel-form, neutron spectrum etc...
BlackWolf18C It isn’t. Cherenkov radiation is the ionisation of air particles. The “flashes” of light the astronauts saw are radioactive particles hitting the back of their retina and causing a nerve stimulation to make their brain “see” light.
Scott, I really miss this kind of video. Crazy stuff whit crazy ships. Galileo conquest is great, but I miss the simple stuff (some time I get lost in what is happening). Have U ever consider doing anoder KSP series whit no mods (or just whit some extra parts) whit the objective of building awesome space station in distant planets? The challenge in assembly it is something that u can beat, but will not be easi and the Kerbal way are really funny XD hahahaha Don't need to be in the career mode. Sandbox or science would be enough :)
Don't the black and white rectangles on the rocket's skin become redundant if the rocket isn't a cylinder? Rolling should be obvious with an X super structure.
Haha I love how he's doing the math as the spacecraft is plummeting toward the mun. "Let's launch this and go to the mun!" Many minutes later... - "Am I going to be able to stop, in time? Let's grab my phone and calculate!"
the world's most ridiculously huge impossible rocket 7:34.........................love this guy!!! Would probably cost 200 billion and blow itself to bits on the lauch pad....
no joke, on my second day of playing I was trying to make a stable orbit for the contract (which I did do later that day) and had a strange parabola around the planet. I later found out the the ellipse ended because I LANDED ON THE MOON. By accident. If only I had decelerated, and brought equipment.
For those interested, info on the United States Army experimental nuclear Stationary Low-Power Reactor Number One accident. "One of the shield plugs on top of the reactor vessel impaled the third man through his groin and exited his shoulder, pinning him to the ceiling" en.wikipedia.org/wiki/SL-1
6:35: The person impaled was not the person who caused the accident. The person impaled was the supervisor of the person who caused the accident. The person who caused the accident was also killed.
4:30 you're wrong, cameras do capture the blue glow, I saw a video where a reactor for research was activated, and it glowed blue on the camera. It was a GoPro that they lowered into the pool.
Well of course they could see it if if was underwater. My point is there's no blue flash in air, but people's eyes are made of mostly water so people see blue flashes.
Can someone explain to me what he calculated @11:42? He says that he should have 40km to spare. But I don't get the same result: v0 = -1500m/s; a = +9,8m/s^2; h = ~180.000m the time it takes to get to v=0 is 1500/9.8 = 153s. The distance traveled assuming constant acceleration is y-yo = 0.5*g*t^2 - 1500*t = -114795m that means there should be 65km to spare. What did I do wrond here?
I'm not entirely sure this method of adding more rockets further outside from your centre of mass is entirely all that efficient :D Would love to see some calculations of how much thrust the outer rockets are providing for your actual craft rather than just lifting their own fuel reserve upwards, compared to the inner rockets which must be way more necessary and adding a lot more delta-v just because they are under your centre of mass.
My favorite comment I saw about Kubrick faking the moon landings "He's such a perfectionist, he would have insisted they film it on location."
Pretty sure Steven Toast witnessed the whole thing, he even told "that" story live on 'Lorraine'
"We actually wanted to fake it in the first place, but after careful consideration we realized it's way easier just to do it for real."
"Catering"
Actually Kubrick hated filming on location and much preferred controlled environments. Full Metal Jacket was shot entirely in England for example.

Scott, if your computer is only 2 years old and "getting hot", you should probably look into dusting it out and cleaning your heatsinks.

I think in the MSR, they may use the method of adding fuel salt slowly to increase the power with the action of control rods. Also in transatomic power design the moderator moves. They may use the method of adding more moderator into the reactor core to achieve this?
In the article "MOLTEN SALT REACTORS - SAFETY OPTIONS GALORE", Uri Gat writes "Early concerns of loss of delayed neutrons, which are carried out of the core in external cooling, turned out to be of no significance."
But, he does not discuss anything how they solved this problem in 7.5 MW MSRE. He writes about continuous removal of poisons and online refueling aids to run the MSR with low excess reactivity. Is this the reason the loss of delayed neutrons was not a safety concern in MSRE?
Because it depends on a bunch of different factors. They weren't doing any helium sparging like some reactor types want to do. Also, size of the reactor matters as the larger you get, the less leakage you get axially. Also the hotter the central axis gets which affects your Dopplar expansion and nuclear resonance for absorption (particularly important for denatured reactors with lots of u238). Basically, like all reactors it takes some engineering and this is one of those things that has to be properly modeled to avoid problems, just like everything else. There is no inherently safe reactor, safe is a matter of design choices is my point.
Doppler expansion and resonance absorption by U238 or Th232 is beneficial. It is responsible for negative temperature coefficients of reactivity. Denatured reactors have strong negative coefficients and it is a good fuel choice.
I agree your point that inherent safety is result of various design choices like the use of inherently safe coolants, fuels, fuel-form, neutron spectrum etc...
Wow! That's a lot of G forces. You broke the Mun racing record and made Kerbal Jam at the same time.
I believe the answer to doing this faster is very clear, MORE BOOSTERS
Oh, man...You killed Jebediah!
The blue flash phenomenon is likely the same explanation as to why astronauts see light spots sometimes.
BlackWolf18C It isn’t. Cherenkov radiation is the ionisation of air particles. The “flashes” of light the astronauts saw are radioactive particles hitting the back of their retina and causing a nerve stimulation to make their brain “see” light.
You blew your rod, and impaled Jose. You give nukes...a bad name...
Scott, I really miss this kind of video. Crazy stuff whit crazy ships. Galileo conquest is great, but I miss the simple stuff (some time I get lost in what is happening).
Have U ever consider doing anoder KSP series whit no mods (or just whit some extra parts) whit the objective of building awesome space station in distant planets? The challenge in assembly it is something that u can beat, but will not be easi and the Kerbal way are really funny XD hahahaha
Don't need to be in the career mode. Sandbox or science would be enough :)
Good luck beating your previous record.
I was Orbiting the Sun the other day @ 500,000 meters, Tried to go EVA, and the poor little Kerbal Vaporized instantly.
When in doubt, strut it out!
Don't the black and white rectangles on the rocket's skin become redundant if the rocket isn't a cylinder? Rolling should be obvious with an X super structure.
Makes it go faster tho :P
Arya Stark True. It also helps finding it if Jeb misplaced it at the pole
You could reduce parachute height to 600 (150 less), becuase you reached the safe speed aroiund 180m above the landing.
Nuclear Reactor lesson from Scott. Sweet :-)
If I were to try this, I'd forget the parachute.
MUN !! makes sense, it sounds right!
that was awesome run
OK, SpaceX has gonna took far.
Haha I love how he's doing the math as the spacecraft is plummeting toward the mun. "Let's launch this and go to the mun!"
Many minutes later... - "Am I going to be able to stop, in time? Let's grab my phone and calculate!"
Your kerbal for sure blacked out..!
Apollo lunar reentrys had a small entry angle of between 5.3 degrees and 7.7 degrees. So not a lot of room for error at those return velocities.
the world's most ridiculously huge impossible rocket 7:34.........................love this guy!!! Would probably cost 200 billion and blow itself to bits on the lauch pad....
no joke, on my second day of playing I was trying to make a stable orbit for the contract (which I did do later that day) and had a strange parabola around the planet. I later found out the the ellipse ended because I LANDED ON THE MOON. By accident. If only I had decelerated, and brought equipment.
Hey Scott, open a window...maybe buy a fan? Science that heat problem. :-D
3 years late
You say it's too hot? OPEN THE WINDOWS!
For those interested, info on the United States Army experimental nuclear Stationary Low-Power Reactor Number One accident.
"One of the shield plugs on top of the reactor vessel impaled the third man through his groin and exited his shoulder, pinning him to the ceiling"
en.wikipedia.org/wiki/SL-1
I'm loving the talk on nuclear physics
"3 kilometers" says the guy who hasn't clipped through the sun.
6:35:
The person impaled was not the person who caused the accident. The person impaled was the supervisor of the person who caused the accident. The person who caused the accident was also killed.
they make this mod called better burn time that has a built in suicide burn timer built in that shows at the nav ball.
your eyebrow reminds me of Mc Donalds. Thanks, I'm hungry now
russians: *sometimes using two days to the iss*
scott manley going to the mun and back in under 90 minutes: Hold ma beer
@7:00 ish - that escalated quickly , the horror
4:30 you're wrong, cameras do capture the blue glow, I saw a video where a reactor for research was activated, and it glowed blue on the camera. It was a GoPro that they lowered into the pool.
Well of course they could see it if if was underwater. My point is there's no blue flash in air, but people's eyes are made of mostly water so people see blue flashes.
My commute to my old job was longer than the time he got to the moon and back, lol
Can someone explain to me what he calculated @11:42? He says that he should have 40km to spare. But I don't get the same result: v0 = -1500m/s; a = +9,8m/s^2; h = ~180.000m
the time it takes to get to v=0 is 1500/9.8 = 153s. The distance traveled assuming constant acceleration is y-yo = 0.5*g*t^2 - 1500*t = -114795m
that means there should be 65km to spare. What did I do wrond here?
I'm not entirely sure this method of adding more rockets further outside from your centre of mass is entirely all that efficient :D Would love to see some calculations of how much thrust the outer rockets are providing for your actual craft rather than just lifting their own fuel reserve upwards, compared to the inner rockets which must be way more necessary and adding a lot more delta-v just because they are under your centre of mass.
Massive Mun Rocket?
Or Massive Mun Manned Missile?
