Release that Witch - Chapter 1221

[Chapter 1191 Rare Elements]

Roland picked out a lead box at random, opened the lid, and held the silver-white metal block 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 the mouth. A couple of licks on the inside can be considered basically harmless.

If you don’t have a deep enough understanding of it, it may be difficult to imagine just looking at its appearance, how amazing power is contained in its small body.

It is by virtue of it that human beings have touched the threshold of mass-energy transformation for the first time.

Compared with all the previous chemical gunpowder, this step can be said to have stepped onto a new level.

Roland roughly counted the number of lead boxes, and it was about fifty. Regardless of the weight of the container, each box was calculated as one kilogram of storage, and it was a full fifty kilograms of uranium 235, whose purity was close to 100%.

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

If you pour them all together…

Maybe the research institute is really “high energy”, right?

“How can these things be used to become the “sunshine” you mentioned earlier?

Nightingale asked curiously, “Make it a special machine, or ignite and detonate it?”

I always feel like they won’t burn.

”

“Want to know?” Roland couldn’t help laughing, “It’s easier than you think, just pile up the metal blocks in the box, and they will automatically emit light and heat. The uranium in this cabinet alone , is enough to raze Neverwinter to the ground, so Lucia’s responsibility is heavy, if she shakes her hands—”

The scene suddenly fell into a dead silence.

Lucia covered her mouth with a look of horror in her eyes.

“…No way,” Azima said in disbelief after a while, “You mean, if we’re not careful, we might destroy the whole city?”

Nightingale leapt forward, snatched the lead box from Roland’s hand and put it back in the cabinet, then grabbed his hand and dragged it out.

“Hey… wait, what are you going to do?”

“Do you still need to ask!” Nightingale said urgently, “Of course I will take you out of the city, and then have these things transported away! Lucia, go and inform Wendy, tell her to contact the administrative office!”

“I…I will also go to Her Highness Tilly,” Azima gritted her teeth, “Only she can call out the Maleficent Curse.”

“Stop—I’m kidding—”

There was a sudden panic in the room, and it took Roland a long time to calm everyone down.

“Are you sure you’re just joking?” Nightingale said unhappily.

“Ahem, of course… what I’m talking about is just the principle,” he quickly added, “but in fact, it’s not that easy to achieve stimulation. Even if I try my best, I may not be able to guarantee success.”

Lucia breathed a sigh of relief, “Your Majesty… you scared my feet so much.”

“This isn’t very funny,” Nightingale glared at him, “If Wendy and Scroll hear this, whether it’s a joke or not—”

“I’m afraid they will all ask to move the new research institute to a place far away from Neverwinter?” Roland said helplessly.

“You know, or you can be moved to a safe place.”

“Well, if I haven’t said those words before…” He cleared his throat, “As long as you don’t say it, Wendy and Scroll won’t know.”

“Perhaps a certain bird has heard it.” Nightingale turned to the window.

“Intercept the news, a bottle of Chaos Drink.” Roland said without hesitation.

“Deal.” She blinked and disappeared in front of the three of them.

Looking at the dumbfounded Lucia and Azima, Roland shrugged, “Uh…don’t worry, this is part of the joke.”

After a while, Nightingale returned to the house, “No suspicious targets were found, but the reward—”

“Still valid.”

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

“That…Your Majesty,” Azima hesitated for a moment before she said solemnly, “What you said before was not all a joke, was it? Because when formulating the rules, you repeatedly emphasized the need to pay attention to weight, and in order to confuse Or the wrong amount, you even precisely control each lead box to four kilograms, and it must be weighed together with the container, so as to ensure that the metal blocks in the box are equal to the greatest extent.” She paused, “And , you said that if there is an accident in the research institute, or there are signs that others have broken in, the first thing to do is to notify the guards to block the scene, and then report back to the castle immediately, instead of entering the courtyard to check the situation. This proves…they do have Certainly dangerous, right?”

Roland looked at her with some surprise, “Good observation. You’re basically right—in addition to toxicity, weight is also one of the key elements, and that’s the purpose of placing them separately.” Can judge the extract from the rules and regulations nature, it can be regarded as cautious and meticulous, it is this carefulness that made her awaken the ability to trace the source… “But weight alone can only endanger the research institute, and I want to make it a weapon against the devil. Weapons, one more thing is needed.”

“Those particles placed alone?” Azima quickly responded.

“Not exactly, but at least half the guess.”

The composition of natural uranium ore is very complex. In addition to uranium compounds, it is usually accompanied by many radioactive substances. Most of them are secondary products after decay. Some have completely lost radioactivity and become stable bodies, while some are still in the long-term. on the way to decay.

Although the Radiant Tribe initially refined the ore when building the Temple of the Cursed, the basic ingredients are still roughly the same—this can be seen from the results of Lucia’s refining.

Among them, uranium 238 is the most abundant. Although it can’t be used as a weapon, it can be recognized by the Rubik’s Cube, and its effectiveness is almost the same as that of uranium 235. Therefore, all of them were sent to the backyard of Beipo Mountain.

The second is uranium 235, which can be regarded as weapon grade if its purity reaches more than 90%. It is refining, and this is also a hurdle that most people cannot cross.

But it is not the rarest one—subsequent decay products such as thorium, radium, radon, and polonium are theoretically rare one by one, and what Roland needs is the naturally occurring polonium 210, which is also a member of the polonium family. The most common isotope.

As a flower of the motherland cultivated in the nine-year compulsory education, Roland is familiar with the two elements radium and polonium. Mrs. Curie, who is repeatedly mentioned in the textbook, is famous in history because of her discovery of them.

Although the half-life of polonium 210 is only more than a hundred days, and its content is appallingly low, so that many extractions by Mrs. Curie have failed, but she is still from the strong radioactivity exhibited by the ore solution. , indicating its existence.

Both radium and polonium can be used to create a neutron source-this is also related to the second difficulty of the brilliant emission: detonation.

The principle of the first-generation nuclear weapons is very simple, and can even be summed up in one sentence: nuclide fission releases energy.

Specifically for uranium, after uranium 235 receives a neutron, it will be excited into unstable uranium 236, and then split into two lighter nuclides and more free neutrons. The quality difference between them is converted into energy.

Obviously, the released neutrons will hit other nuclides, UU Reading www.

sonicmtl.com If this cycle goes on, it is a chain reaction, and the huge energy burst at the same time is no different from an explosion.

But in the microcosm, the gap between the atomic nuclei is like an abyss—just as it is written in the textbook, if the atom is regarded as a football field, then the atomic nucleus is just an ant on it.

If you are unlucky, the neutron will soon fly out of bounds and the reaction will stop.

To ensure that every ant is hit, it is obviously necessary to pile up enough courts around its periphery to ensure that no matter which direction the neutron flies, there is an ant lying across its path.

Reflected in the macroscopic world, the obvious ones are “quality” and “shape”.

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

The specific result requires a lot of calculations based on its shape. Roland also heard an anecdote that the war was lost because someone miscalculated the data.

Of course, as a latecomer standing on the shoulders of giants, he naturally does not have to start from scratch. Numerous experiments have proved that when the object is spherical, the critical mass is the smallest, and uranium 235 is 52 kilograms.

He limited the stock of uranium in each lead box to one kilogram, which is considered prudent enough.

But the so-called critical mass is not fixed. If the area of the stadium can be greatly reduced, or enough extra neutrons can be provided for the nuclide, then its critical value will be greatly reduced.

The former is the principle of the implosion bomb – the detonating explosive is arranged on the periphery of the bomb body, and when it explodes, the reactants are instantly squeezed into one place, causing their density to increase sharply, thus exceeding the critical point.

For Neverwinter’s existing technology, whether it is calculating the critical mass of irregular monomers or precisely controlling the centripetal detonation of explosives, there are too many difficulties, so Roland set his sights on the latter——

A neutron source is used to ensure the continuation of the fission reaction.
