so how close can you get to the core the nuclear reactor without dying well it turns up pretty damn close this is one of the most powerful neutron reactors in the world and in this video and then we get within about eight meters or eight yards of it so this is looking down on the core from on top and this is about where I'm going to get to in this video okay so the runs finished so let's take a look at the sample so we've got all these info ops to stop you already eating us off I crossed the room to the intrinsic field center while he's turning light programs locked in we can't override the time lock here's despite what they say here we go safe this place was you see in the movies are we want gas doubt me okay ah there are no happy endings to being locked in a in the radiation zone they call me dr. Manhattan let's get some air in there so this is the diffractometer and that up there is the reactor and the reactor core is just about there about about eight meters from me so that's one two three four it's about where that wire is just there but I'm going to it's got these radiation meters that give you microsieverts per hour just to put that into perspective backgrounds about point two so we're about twice background here and if you think that's bad right so I'm now within oh good grief Amy visit the course on my that and I'm only it twice background if you think this is bad when you give them their line this will go up to about 2/3 of silver playing so that really am will get a little close to the cool beverages counts that you know let's get a little more active anyway so the reactor core is in there and something all the hot sauce over here which thermal eise's neutrons and so the thermalized neutrons come down into this thing or cat mat it's a big crystal in which monarch roommates the neutrons so right but it's diagram right reactors cause the one over here comes onto the hot sauce hot sauce a radiates a crisp like this it's monochromatic neutrons on to our sample then scatters into the detectors which is this big block thing here that weighs about three and a half tons gram some we're going to get in to the sample cell so I'll need a little bit of air I've put you down for a second don't forgive me until there is most the sample environment so this is the cell these are some oh they're boron rich steel flags which cost an absolute astronomical amount of money anyway so here the radiation isn't too bad but there is some residual that comes off the of the monochromator so yeah it's very localized right so only only keeping your hands out of the that here beam there is what's important about my 10 100 times background or something anyway so the bottom line is if you're a dismount cell spider no one that bit me he must have become radioactive and when his venom reached my bloodstream I've absorbed the proportion of power and abilities of a living spider this manner very quickly let there and just any strip on the top and you're basically done so nice and gentle oh yeah on this mounted cell so so late this is titanium zirconium cell with a liquid sample and it discuss it's about 1,000 bucks or something so from our cell we scatter through this little window here and it goes into these detectors these nine detectors mine detectors all which are fans on and they're helium-3 detectors which is one of the highest concentrations of helium-3 giving a girl apparent and pressurized Meghan whole get helium-3 and harsh but against who okay everybody because the thing is the neutrons that come now maybe this is a good time to actually say something about radiation hazards you see the each one core over there all the reactor core is putting out neutrons for science you have for research purposes and there are two sorts of radiation that you're worried about the first is the sort of electromagnetic which is essentially photons very high-energy photons that's the x-rays and the gammas and we all know camera here with us you're the world of good then an accidental overdose of gamma radiation alters his body chemistry and now when David Banner grows angry or outraged a startling metamorphosis occurs but in reality gammas can be stopped by electrons and the heavier your nuclei the more electrons you get so basically it scales with mass the more mass you have the better your x-ray screening so your typical piece of x-ray screening looks like that big piece of a concrete in fact from the reactor core here just a couple of meters of water will screen most of the x-rays neutrons are a little trickier however because neutrons aren't especially the fast ones screened by electrons so the only way you can really stop a neutron is to actually capture it with a nucleus and when they're captured so that's does essentially what we're doing with a helium-3 detector here the neutrons that come out of here have almost no energy so in order to actually damage living tissue you need to be able to break bonds and bonds are about an electron volt and energy so the neutrons that come through here I only have about a third of an electron volt energy so I don't really have enough energy to even break bombs however there's a problem with neutrons is that they're only got a half-life of about 10 minutes and when they decay they release about a mega electron volt of energy as a millionaire that CommVault certain enough to break a million bonds of living tissue so it's in many ways it's like neutrons are like grenades you don't worry about getting hit by the grenade you worry about it exploded apart from if you had a grenade and it goes bang I'd say grenade weighs about a kilo or something it makes fairly good bang but if that were the the the same mass of neutrons it releases a million times more energy so it'd be like a thousand times killer time so you really don't worry about the the neutrons energy itself you worry about what happens when they decay however neutrons can be captured by certain nuclei like helium-3 and the detectors alright so we detect them there but they can also be stalked by born in boron-10 particularly so this is like a rubber which is a lot of boron-10 in it and yet any much of it you can see right and they capture the neutrons and then when they decay and they release this mega electron volt energy it's just stopped by the concrete which means that me all the way back here behind some more shielding another instrument and some electronics that actually run everything that means that back here I'm actually pretty safe and that's the reactor over there what I think we'll do to start with is we're just going to put the iPod not in the direct beam off to the side just to see what it looks like you

The part I found most interesting about this video was the candid look inside a reactor facility. Frankly it looks kind of janky - dirty, random crap and tools spread all over the place, signs are ripped and crinkled, random wires and other equipment everywhere. Not that this is a bad thing, but just that it is not what I expected for a place that does super high end scientific research. I was expecting like a bright white clean lab with people in lab coats and masks and what not. Though that is probably just my stereotyped view from movies/tv of what it would be like. Cool video OP.

Engineers have better things to worry about than keeping things tidy. I always find my workbench under a pile of wires and other things. Look like an electronics factory exploded.
