Reactor Thread

that guy died of leukemia or something and looked like a methhead

how actual people do it:
-get a degree in physics/nuclear engineering
-get a job with a company with the resources to build reactors

'regular people' shouldn't fuck around with radioactive materials

>>1127479
Wouldn't OP just need lots of lead to not get assblasted by the radiation?

>>1127479
Why in the world would you do that?

This is /diy/. We don't spend money or get degrees here.

>>1127471

To be honest though OP I don't think anyone here knows how to build a reactor

>>1127471
How many smoke detectors would be needed to trip a government radiation detector?

>>1127510

You can build a DIY fusor if you really want to play around with nuclear physics. A fissile reactor is both considerably more dangerous more heavily-regulated.

How is this terrorism? OP just wants to build a small reactor. Likely to power his house or maybe even his whole neighborhood for free.

Don't just assume he's trying to make a bomb

He didn't make a nuclear reactor. He just ended up making things very radioactive from the decay products of radium and radon.

For all practical intents and purposes the only nuclear reactor you can make at home is a fusor.

He had the right idea, but like a typical DIY'er he took shortcuts in construction and safety.

As >>1127582 said you'll want to get soviet smoke detectors unless you want to buy 2 bagillion american ones. Also make sure to cover everything in lead or phone books

Do some reading up on Breeder reactors on the internet and im sure you could do it. The hard part is getting radioactive material. I wonder if you could steal some somehow.

His 'reactor' was sub critical. It was really more of a neutron source with some fissile material surrounding it. It would have bred a handful of atoms of plutonium but it wouldn't have produced any more of a useful energy source than adequately concentrating the sources and harvesting the heat; you can't do this with straight smoke detector sources because they're in a ceramic matrix, making the energy densities too low. You could do something clever to extract the americium but that's a good way to fuck yourself up in a way that would make Hahn look like a pussy.

:(

>>1128120
The Americium in smoke detectors is weapons grade fissile material. However, smoke detectors contain such an incredibly tiny amount of americium that you would need pretty much all the smoke detectors in the world to obtain a critical mass.

>>1127471
>>1128185
This man is correct. And if you read about David Hahn it becomes painfully obvious that this was a boy with WAY too much money and WAY too little supervision. Nuclear reactors of any kind have an inherent initial cost, which is why only governments and enormous companies are the only ones with the capability to do it safely.

You'd need a lot of smoke detectors. Not a fucking chance you'd get a sample of plutonium. Some russian dudes got arrested for taking the plutonium out of smoke detectors and trying to sell it.

>>1129536
Sweet now in order to reach critical mass you need a shitton of it. Oh and if you're using unenriched uranium, you need a shitton of heavy water too.

>>1129668
Is there a cooler one?

>>1127589

Farnsworth Fusor that produces usable energy will kill you horribly without shielding. Also Farnsworth Fusor designs don't have coolant systems.

I recommend using lead as a primary coolant that creates steam by heating water. Lead can self seal some leaks and it doubles as shielding so its the safest coolant for a /diy/er.

I'd use thorium to breed fissionable material, its safer than other options and that field needs pioneering.

Make sure you have good control rods that absorb the fuck out of neutrons and have good coverage through the core. Make sure they don't melt or something.

Acquiring actual reactor grade uranium will be a total bitch so brave the world of thorium :)

>>1130542

Oh and run your lead overpressure valve through the water coolant so if the lead boils it will condense and be contained instead of dispersing through the air you breathe.

Play it safe as possible. And don't fuck with smoke detectors, they only have micrograms of radioactive material.

Radiation can literally blast apart your body at a molecular level, like shooting your cells with the worlds smallest machine gun.

Nothing wrong with wanting a reactor, just gotta be safe.

I wanna make one myself one day if I get too bored.

>>1130545
instructions not clear got dick stuck in machine gun

>>1127504

Building a reactor is actually pretty easy. Take two fissionable masses and smoosh them together until you see a blue flash and die.

Building a reactor that makes enough heat to produce energy but not enough energy to melt is a little harder, but not a lot.

I know this, and my degrees are in Computer Science.

>>1129184
>https://en.wikipedia.org/wiki/David_Hahn

There's a worldwide shortage of plutonium because it's only created in significant quantities inside a nuclear reactors.

Plus, you know, you can make bombs with it. There's a lot of regulatory costs as well.

You can buy it for $4,000 per gram. That's about $1.8 million per pound.

>>1130586

>Take two fissionable masses and smoosh them together until you see a blue flash and die

It's too bad that the only materials that you can practically do this with are extremely expensive and controlled isotopes of plutonium, americium etc. Everything else requires a massive amount of material to sustain a chain reaction.

>Building a reactor that makes enough heat to produce energy but not enough energy to melt is a little harder, but not a lot.

No it's actually quite a lot harder and requires minimum reactor size due to how physics works... unless you have access to the same impractical to get a hold of isotopes or enrichment facilities that can spit out extremely high concentrations of U235.

>I know this, and my degrees are in Computer Science.

Really, I wouldn't have guessed based on how little you know.

agreed. the book sensationalised what he did. reading the accounts of his criminally insane behaviour later in life, I cant help but think all the retards who thought he did something significant ended up encouraging his delusional fantasies.

this is what he actually did: break open as many smoke alarms as he could get his hands on. from schools, public places and steal the americium from them. his bullshit about getting uranium ore samples and doing anything significant with them is bogus. now just to get an idea of how criminally insane he was, think of this. he was arrested because he was caught stealing smoke alarms repeatedly from his apartment. when he was a child and nobody knew what a crazy freak he was, he must have been able to steal every smoke alarm in his school 10x over and from every public bathroom and public building he could. break open the smoke alarm and pile the grain of sand sized piece of americium together. it must have taken tens of thousands of them. he had a really weird niche kleptomania for collecting smoke alarm cores.

>>1127504

the allies only removed the uranium metal out of the chest and the chest remained in the field

rumors state that the netron source (radium) is buried under the chest so you could try to find it

M8, shooting electrons at it ain't gonna do much. Those alpha particles will grab electrons on their own. You will get attoliters per second of helium. In a year you'd produce about 40 picoliters of helium.

Question:
Ive got a Ant hill I want to remove.... is there sufficient quantity to build a working 1-1000th scale Fatman replica to nuke the little buggers?
Answer:
Absolutely! I had a similar problem and built one slightly larger, (which I do not recommend, by the way) and it not only killed all the inhabitants of that hill, it wiped out a nearby herd of Nubian goats. There were HAZMAT crews and folks from Homeland Security combing the hills for weeks. I think it was the noise
