Chapter 569: The Edge of Crisis
In fact, even if the nuclear material reaches the concentration required for the reaction, the nuclear reaction may not necessarily occur.

Although uranium 235 can release neutrons by itself, the half-life of uranium 235 is as long as 7 million years, and it usually only releases a small amount of neutrons.

Under normal circumstances, these neutrons will basically leak out and will not trigger a chain reaction of low-enriched uranium.

But Yang Dongsheng first enriched all uranium elements, and then enriched uranium 235 separately.

In uranium ore, more than 99% of the uranium element is uranium 238. Yang Dongsheng's method has caused the outer core of uranium 235 to be wrapped with an ultra-thick layer of uranium 238.

In the process of manufacturing nuclear bombs, in order to reduce costs and reduce the amount of expensive weapon-grade enriched uranium, a layer of uranium 235 is often included outside uranium 238 to improve nuclear reaction efficiency and reduce critical mass.

Uranium 238 is a good neutron reflective material, and a layer of uranium 235 is wrapped around uranium 238, which can reflect back a large number of neutrons that would have been leaked.

Now Yang Dongsheng has gathered together a large amount of low-enriched uranium. Outside these uranium-235, there is an ultra-thick uranium-238 neutron-reflecting layer...

So a uranium-235 nucleus absorbs a neutron, splits into two nuclei with a smaller mass, releases a lot of heat, and releases 2 to 3 neutrons at the same time—how many will be released is not certain.

These newly produced neutrons will bombard another uranium-235 nucleus, triggering new fission...and a chain reaction takes place!
Yang Dongsheng now wants to thank the uranium-238 layer that caused trouble before. Its main components are metal uranium and uranium oxide. This is a ceramic material that is not only high-strength, but also resistant to high temperature and corrosion. It is the depleted uranium bomb commonly used by Americans. Done, they wrapped up the nuclear reactor.

In addition, this uranium mine is several thousand meters deep underground, surrounded by thick rock formations, and Mongolia still lacks water.

Otherwise, just entering the new millennium, mankind will encounter a nuclear accident that is dozens or hundreds of times more serious than Chernobyl.

Looking at the already mushy magma, Yang Dongsheng knew that it would be impossible to stop the nuclear reaction by moving the uranium 235 out of the reactor.

Yang Dongsheng didn't dare to touch the shell around the reactor. Now he relied on it to prevent this nuclear disaster. He could only use several kilometers thick granite to completely enclose the nuclear reactor.

The next step is to extinguish this underground nuclear reactor, the method is ready-made - borax.

After the Chernobyl nuclear accident, the Soviets sprinkled a lot of borax.

Natural boron is composed of two stable isotopes, boron 10 and boron 11, of which boron 10 accounts for about [-]%.

The nucleus of boron 10 easily absorbs a neutron and turns into a lithium ion, while emitting an alpha particle and gamma ray.

With no neutrons scurrying around, the chain reaction stops.

Yang Dongsheng has a borax mine under his command.

But after spreading it down, Yang Dongsheng was dumbfounded.

The density of borax is about 1.7 tons per cubic meter, while the density of magma is about 2 tons per cubic meter. More importantly, natural borax is actually a sodium borate hydrate, which will release water after heating...

Although he just put a little borax in and quickly took it back, Yang Dongsheng still couldn't help the cold sweat on his forehead.

In the guest house of the Municipal Party Committee and Municipal Government of Ma City, a man suddenly screamed, "Ah!"

Then there was a bang, and someone kicked the door open.

"Zhou Ying, wake up the kid! Where are the crew members? Get up, get up! Get the plane ready and take off immediately, let's go back to Shanghai!"

Yang Dongsheng yelled, but found that no one paid him any attention.

It took a while to see the door of the next room open, and a young woman came out.

"Hush! I finally fell asleep!" Zhou Ying made a small gesture first, and then said to himself, touching Yang Dongsheng's forehead, "I didn't drink much today, why did you go crazy?"

Yang Dongsheng jumped up when he heard the words, "Who is crazy about drinking, I am not drunk at all? Listen to me, I don't have time to explain to you now, just do as I said, tell the children to get dressed, let's go back to Shanghai Come on, or it will be too late!"

"Okay, okay, you're not drunk, let's go back to the house first?" Zhou Ying said as if trying to persuade the child.

Yang Dongsheng immediately became angry when he heard the words, "What house are you going back to? You still think I'm drunk, where are the crew members? Didn't you hear me? Get ready for the plane, we'll take off right away!"

The people in other rooms on the same floor were finally woken up by Yang Dongsheng at this time, several doors opened, and Vice President Jiang and Vice President Zhao came out of the room.

"President Yang, what happened?" Vice President Zhao asked.

Only then did Yang Dongsheng realize that their floor seemed to be full of executive suites, and no one else lived here.

Yang Dongsheng ignored them, ran downstairs and knocked on the doors of each room.

Finally, a middle-aged man and two young girls walked out of one of the doors. They were hurriedly getting dressed, and they were the captain and two flight attendants.

Yang Dongsheng said in his heart, it's fun enough!
"Get ready for the plane, let's go back to Shanghai!" Yang Dongsheng said.

The captain was taken aback, "Have you applied for the route?"

Zhou Ying chased after him from upstairs, waved at the crew, and signaled them to go back to the house, and pointed at the people who came out of the other rooms, "You guys take Mr. Yang back!"

Seeing several burly employees rushing towards him, Yang Dongsheng glared, "Get out of the way!"

Yang Dongsheng pulled several employees aside, and they looked at Zhou Ying together.

"What are you still doing in a daze, take Mr. Yang back!" Zhou Ying stamped her foot, grabbed Yang Dongsheng's arm first, and pulled him back.

Seeing this, several workers carried Yang Dongsheng back to the house in a hurry.

Yang Dongsheng was going crazy, "Let go of me! You idiots, if you don't leave, something big will happen!"

At this time, everyone on the whole floor woke up. The door of the second bedroom opened, revealing a small head, wearing a small pajamas, lying on the doorway like a thief, with two eyes shining.

A door on the other side also opened, revealing two little heads, one of them said, "How much did my uncle drink?"

"Looks like I drank a lot!" said another.

Yang Dongsheng finally gave up, he found that he couldn't leave today anyway, "Okay, I won't leave, but you have to find me a computer, a computer with Internet access!"

There must be more than one substance, borax, that can block the chain reaction, but what to replace it with, Yang Dongsheng had to look it up online.

"Where can I find you a computer at this time? It has to be a computer that can access the Internet. We'll talk about it tomorrow when you sober up, okay?" Zhou Ying said.

Yang Dongsheng thought that this is not the future, and suddenly he saw the phone beside the bed, "Can this phone make international calls? Call Yang Huai!"

"Yang Huai's family must have fallen asleep!"

"Then wake him up!"

Zhou Ying had no choice but to make a phone call.
