Chapter 1191 Rare Elements

7days ago Xuanhuan Novels 9
Roland picked out a lead box, opened the lid, and held the silver-white metal block inside in his hand, feeling its heavy weight. Before it was activated, it was not much different from a piece of pure iron. As long as it was not put in its mouth and licked it for two times, it could be regarded as basically harmless.

If it weren't for having a deep enough understanding of it, it would be hard to imagine just looking at its appearance. What an amazing power is contained in its small body.

It is precisely because of it that humans have touched the threshold of mass-energy transformation for the first time.

Compared with all the chemical gunpowder before, this step has taken a new level.

Roland roughly counted the number of lead boxes, about fifty. Putting aside the weight of the container, each box was calculated based on one kilogram of storage, which was a total of fifty kilograms of uranium 235, and its purity was nearly 100%.

And there is more than one lead cabinet like this in the room.

If they were poured together...

Maybe the institute is really high-energy, right?

How to use these things to become the sunlight you mentioned before?Nightingale curiously, to make a special machine, or to ignite and detonate?I always think they can't burn.

Want to know?Roland couldn't help but smile, "It's simpler than you think, just pile the metal blocks in the box together and they will automatically emit light and heat."The uranium in this cabinet alone is enough to razure Wu Winter City to the ground, so Lucia's responsibility is heavy, if you shake your hands

The scene suddenly fell into a dead silence.

Lucia covered her mouth, her eyes showing a look of horror.

...No, it took a while before Aqima could not believe it. What do you mean, if you are not careful, we may destroy the whole city?

Nightingale even jumped into a flash, snatched the lead box from Roland's hand and put it back into the cabinet, then grabbed his hand and dragged it outward.

Hello...wait, what are you going to do?

Do you still need to ask?The Nightingale said anxiously, of course, it is to take you out of the city and then let someone transport these things away!Lucia, go inform Wendy and ask her to contact the Executive Hall!

I...I'll go to find His Highness Tilly, Aqima gritted her teeth, only she could scream the Maleficent Curse.

I'm joking to stop

The room suddenly became messy, and it took Roland a long time to calm everyone down.

Are you sure you're just kidding?Nightingale said angrily.

Ahem, of course... I was just talking about the principle, he quickly added, but in fact, it is not that easy to achieve inspiration. Even if I put all my strength into it, I may not be able to guarantee success.

Lucia breathed a sigh of relief, Your Majesty... You scared my feet soft.

It wasn't funny, Nightingale glared at him, if Wendy and Shuju heard this, whether it was a joke or not

I'm afraid they will ask to move the new research institute far away from Wu Winter City, right?Roland said helplessly.

Just know, or move you to a safe place.

Well, when I hadn't said the previous words... He cleared his throat. As long as you didn't say it, Wendy and the Book wouldn't know.

Maybe a certain bird has heard it.The nightingale glanced out the window.

Cut off the news, a bottle of Chaos drink.Roland said without hesitation.

make a deal.She blinked and disappeared in front of the three of them.

Looking at Lucia and Akima who were stunned, Roland shrugged, uh... don't care, this is part of the joke.

A moment later, the Nightingale returned to the house, no suspicious target was found, but the reward

Still effective.

Her expression finally calmed down, and she hummed a little and went to chew the dried fish.

That... Your Majesty, Aqima hesitated for a moment before saying solemnly, what you said before was not all jokes, right?Because when making rules, you have repeatedly emphasized the need to pay attention to weight, and for confusion or incorrection, you even precisely control each lead box to four kilograms, and weigh it together with the container, which can maximize the equality of the metal blocks loaded into the box.She paused, and, you said that if an accident occurs in the institute, or there is a sign of someone else breaking in, the first thing you need to do is notify the guards to block the scene, and then go back to the castle to report immediately, instead of entering the yard to check the situation.This proves...they are indeed dangerous, right?

Roland looked at her with some surprise, with good observation.You are basically correct, in addition to toxicity, weight is also one of the key elements, and this is the purpose of separation and opening.It is considered to be cautious and meticulous to be able to judge the nature of the extract from rules and regulations. It is this carefulness that has awakened her ability to trace the origin...

But weight alone can only endanger the institute. To turn it into a weapon against the devil, another thing is needed.

Those individually placed particles?Aqima quickly reacted.

Not exactly, but at least half guessed.

The composition of natural uranium ore is very complex. In addition to uranium compounds, it is usually accompanied by a lot of radioactive substances. Most of them are secondary products after decay. Some have completely lost their radioactivity and become stable bodies, while others are still on the long road to decay.

Although the Radiation Clan performed preliminary refining of the ore when building the Curse Temple, the basic components are still roughly the same, which can be seen from Lucia's refining results.

The most abundant content is uranium 238. Although it cannot be made into a weapon, it can be identified by the Rubik's Cube. Its effectiveness is almost the same as that of uranium 235, so it is all sent to the backyard of Beiposhan.

The second is uranium 235. If the purity reaches more than 90%, it can be regarded as a weapon level. The natural content is extremely low, accounting for only 1% of the natural uranium elements. Therefore, the first difficulty encountered when you want to take the brilliant radiation route is refining, which is also a hurdle that most people cannot overcome.

But it is not the rarest subsequent decay products such as thorium, radium, radon, and polonium. In theory, each one is rare. What Roland needs is the naturally occurring polonium 210, which is also the most common isotope in the Polonium family.

As a flower of the motherland cultivated by nine years of compulsory education, Roland is familiar with the two elements of radium and pole. Madame Curie, which is repeatedly mentioned in the textbook, is famous in history because of the discovery of them.

Although the half-life of Polynium 210 is only more than a hundred days and its content is so low that Madame Curie's multiple extractions have failed, she still pointed out its existence from the powerful radioactivity shown by the ore dissolving solution.

Whether it is radium or polonium, it can be used to manufacture neutron sources. This is also related to the second difficulty of brilliant radiation: detonation.

The principle of the first generation of nuclear weapons is very simple, even so simple that it can be summarized in one sentence: nuclide fission releases energy.

Specifically on uranium, uranium 235 will be excited into unstable uranium 236 after receiving a neutron, and then split into two lighter nuclides and more free neutrons. The poor mass between them is converted into energy.

Obviously, the released neutrons will hit other nuclides. If this cycle continues, it will be a chain reaction, and the huge energy bursting out at the same time is no different from an explosion.

However, in the microscopic world, the gap between the nuclei is like a world of heaven. As the textbook writes, if the atom is regarded as a football field, then the nucleus is just an ant on it.

If you are not lucky, the neutron will fly out of bounds soon and the reaction will stop.

To ensure that every ant is hit, it is obvious that enough courts must be piled up on its periphery to ensure that no matter which direction the neutron flies, there is an ant crossing its path.

Reflecting to the macro world, the obvious ones are mass and shape.

In fact, critical mass is not a fixed value, just like a stadium lined in a straight line is obviously not as good as a stacked stadium in terms of chance of being hit.

The specific results need to be calculated in large quantities based on their shape. Roland also heard an anecdote that the war failed because someone miscalculated the data.

Of course, as a latecomer standing on the shoulders of a giant, he naturally doesn't have to start from scratch. Countless experiments have proved that when an object is spherical, the critical mass is the smallest, while uranium 235 is fifty-two kilograms.

It was a prudent enough to limit the stock of uranium in each lead box to one kilogram.

But as the saying goes, the critical mass is not fixed. If the area of ​​the field can be greatly reduced or enough additional neutrons are provided for the nuclide, the critical value will drop significantly.

The former is the principle of the internal detonation bomb. The detonation explosive is arranged on the periphery of the bomb body. During the explosion, the reactants are instantly squeezed into one place, causing their density to increase sharply, thus exceeding the critical point.

For the existing technology of Wu Winter City, there are too many difficulties in calculating the critical mass of irregular monomers or precisely controlling the centripetal detonation of explosives, so Roland turned his attention to the latter.

Use neutron sources to ensure the continuous progress of fission reactions.
