How to they separate uranium 238 from 235? One of them is three neutrons heavier! How do they do it? Is there a way of taking out three neutrons from 238 to become 235?

Gas Centrifuge is one way. The uranium is heated up until it is a gas and then spun around to seperate the isotopes.

doesn't that take really special equipment? Also, how big is the gas centrifuge?

Yes it takes special equipment, which is why so few countries around the world are able to produce enough to make nuclear weaopns.

Thanx alot. Amazing link!

Here is a little more on gaseous diffusion separation.

Thanx alot!

I use a sieve.

how does that work??? Or is this one of ur jokes

Reallllly fine mesh

is the mesh fine enough to let U235 enter, but not U238? And if that was the case, then, countries would not be caught out because the equipment, i was told was very big! I yet think this is another one of ur jokes

Yeah, U235 goes straight through but U238 gets it's neutronies caught.

ok. THAT i don't beleive! The thing about this forum is that i can't tell the tone of ur voice

lol

 

I posted a picture of a hand sieve; of course it's a joke. Where would I get U235 from anyway?

You just LOVE to pull peoples' legs don't you! That last post actually made you loose folling me, the one about the neutrons! I was going to beleive you! The seive, i knew that it wasn't a real one, cause i looked at the adress, as it was something to do with ceramics. I DID think that you wanted to show me what a seive looks like, and i was thinking 'What was THAT for?!"

 

Nice!

lol

 

So close!

yup! and u ruined it urself! I actually added some reputation points for that! Its was a mean trick!

Muah ha haa

you horrid person!

...but funny

yeah. I have to admit that he has a good sense of humour! I like people like him!
