Therefore you are saying you have your doubts

I'm simply saying I do not know.

Let's try it another, unfortunately slightly vulgar way. On a scale of 1-10, how likely do you think it is that the holocaust happened?

[Monkeys Fist 43079]

How old would you say the Earth was Wolfy?

a- less than 10 million years

b- between 50 million and 10 million years

c- 4.54 billion.

 

Choose one option please.

Spell it out for him

1 being it didn't happen

10 being it definately happened.

I've never weighed it up so I don't know.

zzzz let this thread die already.

Sending out some random texts atm, lets see if I can lure something twolegged and with a puls over.

Couching with a semi atm.

so you've had time to consider fucking Beagle 2 but not got round to the biggest cultural event (sounds like a rave, apologies) in living memory???

 

Jeeeeesss Loooouiiiise.

satellites yes, ISS yes, moon? one question , if we lose the ozone layer or magnetosphere we all die from solar radiation yet the apollo missions made it because there werent any solar events?? or do we just need the tinfoil? , whats wrong with mission to mars? its not a pure vaccuum and your pushing against earths gravitational drag for the first 1200 miles anyway

Fucking hell, what a catch you must be.

Fucking hell, what an episode of "To Catch a Predator" you must have been involved in.

Uranium is mined and mixed with a few ingredients into the HARD metal, it's then made into pellets which are only supposedly mildly radioactive.

It's then put into long tubes and bundled together.

 

 

Uranium compounds are mined, typically oxide form. This is extracted from rock and purified into form called 'yellow cake' or U3O8 in chemical composition. To convert it into modern fuel it is first turned into a gas by reacting it with flourine to get a compound known as 'hex' or UF6. It is then enriched to between 3 and 5% U235 (natural uranium is 0.7% u235) in a series of centrifuges or a huge gas diffusion plant. The uranium is then converted to uranium dioxide and turned into polo mint shaped pellets for use in a reactor.

 

At this stage it is pretty benign as uranium has a very long half life its pretty stable. It will only do you harm if you decide to chow down on it as alpha radiation is pretty harmless unless it gets inside you.

 

The first generation reactors used natural uranium metal fuel but these consisted of long bars covered in a magnesium alloy.

 

They then start getting bombarded by neutrons and it split the atoms inside the heavy super steel hard uranium and it glows like the sun for years.

Even after years of use, it's only supposedly used about 20% of it's fuel (atoms) and they take them out of the reactor and put them in SPENT fuel pools to cool down which takes years lol.

 

The problem now is, they have went from mildly radioactive to ultra poisonous even though it's been used for 5 or 6 years supposedly fissioning.

 

Uranium isnt a particularly hard metal, its just very dense. It doesn't glow. It looks just like a bog standard lump of steel and is about as harmful as a big old lump of steel. When a reactor is on there is a characteristic blue glow which is cherenkov radiation, but you can only see in a swimming pool type reactor. Its fully contained within the steel or concrete walls of power station reactors.

 

Fuel typically stays in the reactor between 18 months and 5 years depending on its location in the reactor. The central sees more neutrons so is used up faster then those at the edge. When its taken out of the core there is still plenty of u235 left and a bit of plutonium and lots and lots of fission products. The most common fission products are things like caesium 137 and strontium 90 but basically every element lighter then uranium will be present in small amounts.

 

It is the radioactive decay of these fission products that gives off the heat and the vast majority of the radiation. Its not poisonous, just very radioactive. If you were stand next to an unshielded fuel rod for about an hour you would recieve a dose of approx 4 Sieverts and would stand a 50% death from acute radiation sickness. If you survive that you would face a 20% chance of receiving cancer due to the radiation later in life.

 

Now bear in mind, these pellets are hand held sized pellets, similar to what you see at the start of the Simpsons where Homer throws one out of his car, still glowing lol.

 

Now they can hold spent fuel rods inside these pools for decades and decades and then they have to dump them somewhere inside flasks of lead and concrete and what not, yet they can also be re-cycled apparently. Hmmmmm, work that one out.

 

 

The pellets are a lot smaller then you think, they are much closer to polo mint size. You are correct with the pools, the fuel is stored in 10m ish deep pools. Water is a very good radiation shield and excellent at removing the heat.

 

The left over uranium and generated plutonium in spent fuel can be stripped out of the spent fuel and reused in new fuel. This is done by dissolving the spent fuel in nitric acid. Then using an organic solvent to extract the plutonium and uranium leaving behind a highly active liquid of fission products called 'HAL' and a plutonium and uranium mixture which can then turned into more fuel. This is done as it saves having to go through the highly expensive and energy intense uranium enrichment process.

 

The HAL fission products are then concentrated in an evaporator and vitrified in a special kind of glass to immobilise it. This glass is then placed inside steel boxes and is currently stored in sellafield. There is work looking at building a large underground vault as the permanent place to dispose of these.

 

The depleted ( supposedly highly poisonous) uranium can also be made into tips for artillery shells and tank shells, that I would assume can only be used by tank commanders dressed in nuclear fall out suits with big helmets.

 

You won't be able to go anywhere near this stuff because if you do, you will fall to the ground frothing at the mouth and if you aren't wearing factor 26 million, your skin will be ruined.

 

Depleted uranium is the left overs from the enrichment process I mentioned at the top. Its never been anywhere near a nuclear reactor and is harmless, unless of course its shot at you from tank cannon. Its used as its very dense and due to the extra weight will penetrate armour. Again as long as you don't decide to have a big old depleted uranium tank shell sandwich you will be fine.

 

Granite is more harmful in terms of radiation then depleted uranium is. Your skin will be fine and the level of sunscreen you recommend is not required!

 

This very same stuff sits in a big sealed container full of water and it glows, heating it up, yet the very same stuff, with a few drops of plutonium added, which is supposedly another metal can be made into discs and bullet shapes.

 

You can then smash both pieces of metal together..(and remember we are talking about palm sized pieces of metal) and BANG, you can blow up a city and cause radiation fall out that lasts for hundreds and hundreds of years.

 

They want us to believe in magic and it doesn't get much more magical than this.

 

Now if people want to go on believing that we can blow this planet up with these things, then I don't have any problem with that. Yet when the time comes when the threat of nuclear war is on the cards, (which I believe it won't belong) I will be sat with my feet up smiling while many people will be trying to keep their own poo in.

 

Its not the same stuff, its different. Depleted uranium is U238, the stuff that reacts in reactors is U235. Neither glows.

 

The stuff in bombs is either very very highly enriched uranium (95%+ U235, compared with the 0.7% in natural uranium) or Plutonium 239. The amount you need to make a bomb is significantly more then you have as well. If you take 2 coke can sized lumps of this highly enriched uranium (660ml, which weighs approx 12kg) shape it into 2 hemispheres and bash them together nothing will happen other then a rather dull thud. You wont get any fissions or radiation other then the very very small amounts given off from the alpha decay.

 

The aim in the 1950s was to create 1 megaton tnt equivalent bomb from 1 tonne of uranium/plutonium. The ones you mention are the designs from hiroshima and nagasaki, and that is a very simplified version of how they work. Your masses are well off the mark, think several hundred kgs, not hand sized lumps. The hardest part in making the bombs is stopping them blowing apart too early, as that is what they naturally want to do. To make them explode is actually ridiculously complicated, you can get a fizzle relatively easily where only part of the fuel is used but to get a full bomb you need a very precise timing and a great deal of tnt to keep the material together.

 

The residual radiation from bombs isn't so bad as there is it very dilute, hence why there are still cities in japan rather then wastelands where hiroshima and nagasaki once stood. When the bomb goes off there is a huge pulse, but after its gone the radioactive matter is spread far and wide. The black rain that fell from the eye witness reports in hiroshima was the soot from the secondary fires with a great deal of active fission products trapped on them.

 

As for a previous statement about the industry being secretive, all the information in this post is freely available online and accessible with google or in any number of books. If you genuinely have interest in this and want to know more I will happily point you towards free resources online that give more detail then you can shake a stick at.
