Hunter of the Forbidden Region

Chapter 618: Nuclear accident

Views:

Lin Shuo is an inheritance hunter and a rural teacher.

Teachers must prepare lessons in class, otherwise they will mislead their children, and hunters must prepare in advance when hunting, otherwise their lives will be lost.

The hunter's preparation is a matter of life and death, the more detailed the more meticulous.

For this Chernobyl deal, Lin Shuo would naturally do his homework.

It seemed that this was a live broadcast show, and Lin Shuo took on the job of live streaming, selling a limited-edition backpack.

But in fact, he knew in his heart that it must not be that simple.

With just his handsome face, he can sell the goods. If the business is so easy to do, then every handsome guy in the world can get rich.

This is obviously a pretext, Tang Gaojie must have other plans.

As for Tang Gaojie, Lin Shuo was proud of his old man's storytelling mouth, so he understood.

This is called the origin of family learning. The threshold of the Lin family is nine inches nine, and the position of the leader of the hunting gate. Putting aside other abilities, the first thing to do is to know people.

Knowing people without knowing them is a greater crime than incompetence.

Therefore, Lin Leshan had already broken up and chewed up the names of the characters in Jianghu, what industry, what ability, and temperament, and fed them to his son.

Tang Gaojie is a few years older than the Four Elites of Liemen headed by Lin Leshan, and he was originally a romantic figure of their generation.

Since the Su family moved to the foot of the Kunlun Mountains during the Northern Song Dynasty, the Tang family was in charge of the area in central Sichuan.

The Tang family in the middle of Shu, this is the seven-inch family of Liemen, a time-honored family, with talented people coming out in large numbers. When Tang Gaojie came out of Yicheng, he was once very popular.

Until one time, he formed a team with Lin Shuo's father and made a deal.

At that time, Lin Leshan was just a fledgling, with the reputation of his father Lin Chaodong as a romantic, that was the time when the heirs of the Lin family had the worst reputation.

However, Lin Leshan and Lin Shuo did not elaborate on the process of this business transaction. In short, in the end, when compared between the two, Lin Leshan was far superior.

At that time, it wasn't just the two of them who formed the team, and the news spread, and it quickly spread throughout the door, and the reputation of the two of them was reversed.

Tang Gaojie is not a narrow-minded person, he didn't blame Lin Leshan for this matter, but he didn't like it in his heart.

He ran over to have a drink with Lin Leshan, and then played cards with Lin Leshan all night.

Lin Leshan's card skills have always been stinky, and after thirty years, he will not be the opponent of the Su brothers. The consequences of meeting the future God of Gamblers can be imagined.

After abusing the descendants of the Lin family at the gambling table, Tang Gaojie went out laughing, and then went to the United States alone.

This was nearly forty years ago.

He made his fortune in the United States and moved the entire Tang family in central Sichuan to North America.

He and Miao Guangqi are similar in temperament, and they like to do things bigger.

Selling goods live, he is interested in this kind of crap.

Moreover, he was somewhat unconvinced to the heirs of the Lin family.

So for this business trip, Lin Shuo had to do his homework.

If you don't prepare well in advance, you might lose your old man when you come here.

Sure enough, there's something here.

The current hideousness at these two ends may be the surprise that Tang Gaojie prepared for himself.

If Lin Shuo handles this surprise well, it will be considered a surprise. If it is not handled well, it will cause the whole world to panic.

Chernobyl, this place is so special.

Especially the place where these two hideous heads are currently staying is even more unusual.

This is Unit Four of the Chernobyl Nuclear Power Plant.

The nuclear reactor that had an accident twenty years ago is here.

The general principle of a nuclear reactor is to use the fission of low-concentration uranium-235 to generate energy. This process is controllable, and then use the fission energy to generate electricity.

The fourth reactor of the Chernobyl nuclear power plant is called the graphite-moderated boiling water reactor.

The principle of graphite moderation is too complicated to mention first.

And boiling water, this simple, is to boil water.

The circulating cooling water enters the reactor to be boiled and then pumped out, and the steam generated by the boiling water is used to drive the generator turbine.

At that time, the water pump was to be tested here. This water pump was required to continue to work and pump out hot water when the nuclear reactor temporarily did not provide energy.

This pumping of hot water is critical, otherwise the accumulation of high temperatures will be dangerous.

The matter of powering the water pump is a diesel generator, so that the water pump can continue to work.

But it takes a minute for the diesel generator to start, and the heat accumulation in this minute is enough to see, and accidents are prone to happen.

Engineers had a new idea, thinking that they could use power plant steam to drive electricity generating turbines.

The nuclear reactor is temporarily not providing energy at this time, but the turbine has inertia, and the power vacancy of the water pump for one minute can be filled by the inertia of the turbine.

The idea is wonderful, but at that time it was regarded as a technical gap, and problems would arise in practice.

Three experiments failed, and on the fourth, something went wrong.

April 26, 1986, was exactly twenty years ago by two months.

At that time, a small power station next to Kiev, the capital of Ukraine, was suddenly shut down, which caused the capital's electricity shortage.

The nuclear power plant test is to shut down the reactor and stop generating electricity.

The Electric Power Bureau asked the nuclear power plant not to conduct the fourth test during the day, but to move it to midnight, when the city does not use much electricity.

The factory director agreed at the time, but this brought two problems.

First, according to the shift schedule of the factory, the technical backbones are all on daytime shifts, and the night shifts are all young operators who have just started work.

So this complicated test task fell on these young people.

At that time, the operator was twenty-five years old and had only been on the job for four months. He was ignorant of this kind of work.

The second problem is the technical problem inside the nuclear reactor.

During the day, the reactor was kept running at half power because it was going to be tested, and then it was suddenly delayed.

The half-power operation causes a large amount of iodine 135 accumulated in the reactor for several years to continuously decay into xenon 135.

Xenon 135 has an extremely high concentration in the middle of the night and early morning.

Xenon 135 has the effect of absorbing neutrons and hindering nuclear reactions.

The test started in the middle of the night, and the power of the nuclear reactor continued to be reduced, and the high concentration of xenon 135 began to act as a demon.

The power of the nuclear reaction dropped hopelessly fast.

So far, there is still help.

Shut down the reactor for 24 hours, xenon 135 itself will decay and disappear automatically.

But shutting down the reactor meant that the fourth experiment failed completely.

This result was obviously unacceptable to the acting chief engineer at the time.

This is where it starts to kill.

Knowing that what he was going to do next violated safety regulations, the acting chief engineer asked the operator to shut down the automatic control system and alarm system and switch to manual control.

This operation is the reverse of the previous one, and the purpose is to pull up the power of the reactor a little, so as to simulate the normal operation of the reactor as much as possible.

But at that time, the concentration of xenon 135 inside the reactor was still very high, which hindered the nuclear reaction, and the power could not be increased.

As for the manual operation, in fact, the control is already full.

Then the water pump started to operate, and the water at the bottom was gradually pumped out, but this process was not so fast. The heat accumulation before the circulating water system still caused the water remaining in the reactor to start boiling.

When water boils, bubbles are formed.

Water absorbs neutrons and can inhibit nuclear reactions.

Once bubbles are generated, this inhibitory effect is reduced.

At the same time, iodine 135 is depleted, xenon 135 has no source to replenish, and the concentration begins to decrease.

So at the same time, the effects of the two substances that inhibit the nuclear reaction begin to decline.

This decline is not linear, but exponential.

Suppressing the decline, the power of the nuclear reactor began to climb rapidly, and soon became uncontrollable.

The acting chief engineer panicked at this time and quickly ordered the shutdown of the nuclear reactor.

But this thing is not as simple as a power switch, just turn it off.

At that time, the switches of this nuclear reactor device were two hundred and five control rods.

The upper half of the control rod is boron, and the lower half is graphite.

Boron inhibits nuclear reactions, graphite promotes nuclear reactions.

The principle of this switch is that the rod is inserted in the reactor, and the power of the reactor is controlled through the contact between the upper half of the boron and the lower half of the graphite and the reaction substances.

At the beginning, the acting chief engineer wanted to increase the power, so the twenty-five-year-old young operator pulled up the control rod, so that the lower half of the graphite could get more contact with the reactive substances, that is, uranium 235 and uranium 238, to promote nuclear reaction.

The guy was inexperienced, and thought that the higher the pull, the greater the power, so the operation was fully pulled out, and all 205 sticks were pulled out manually.

So even the lower half of the graphite was pulled out, all suspended above the reaction substance.

At this moment, the acting chief engineer said to shut down the nuclear reactor quickly, and the young man then controlled the rod to be inserted down.

In this insertion, the first contact with the reaction substance is the lower half of the graphite, which promotes the reaction.

This is called adding fuel to the fire.

The reaction increased dramatically to tens of gigawatts, the water was vaporized in an instant, and the resulting pressure distorted the reactor.

The control rod was stuck in it and could not be further inserted, the lower half of the graphite was stuck in the middle of the reactor, and the upper half of the castellation could not go down.

So the inside and the outside add up, and it's completely out of control.

The final meter reading was 33 billion watts, ten times the normal power.

The reactor core melted instantly under the ultra-high temperature, and the 1,400-ton reactor top was thrown into the air by the steam explosion.

Then oxygen enters the reactor, and all combustible substances detonate rapidly at high temperatures.

The violent explosion scattered graphite wrapped in radioactive substances.

A faint blue beam of light appeared above the nuclear power plant.

That is the spectrum that appears when atoms in the air absorb high-energy rays, become excited, and then return to a non-excited state.

The reason why nuclear radiation is terrible is that this high-energy ray is released in the form of kinetic energy, and the molecules will fall apart.

The genes of the human body, the genetic information carried by DNA, is molecular information, and will be smashed to pieces.

When the genetic information is destroyed, the metabolism of the human body will not work, and the cells cannot be replaced, so they will die slowly.

So once you suffer from high-intensity nuclear radiation, there is no cure.

This incident, the largest nuclear accident in human history, was designated as the highest level seven disaster event.

The power of all the radioactive materials is equivalent to one hundred and forty Hiroshima atomic bombs.

How the Soviet government responded to the disaster afterwards was an epic action, and Lin Shuo was very moved when he saw it in the library in Northern Europe.

In short, in the end, after sacrificing thousands of lives and discounting the lives of tens of thousands of rescuers, all radioactive materials were finally sealed up.

It is a huge sarcophagus that seals these substances, which is just above the No. 4 nuclear device.

And this sarcophagus has a life span of about thirty years.

Thirty years from now, the sarcophagus itself will also be a radioactive source.

Now that twenty years have passed, this sarcophagus has ten years left to be used, and within ten years a bigger one will be needed.

And the current two hideous ones are on the top of the sarcophagus, standing on one end and lying on the other.

These two things don't take nuclear radiation seriously, of course it's their ignorance as ignorant creatures.

Without Lin Shuo hunting them, the lifespan of these two creatures will not exceed a week in the future.

But now two groups of people collided, you saw me, and I saw you, this is a narrow road encounter.

It won't take as long as a week, and now we have to meet life and death.

The place where Lin Shuo chose to meet the two fierce beasts was on top of the sarcophagus.

If the two ferrets were placed elsewhere, Lin Shuo asked himself that the problem would not be too big. The descendants of the Lin family have hunting experience for this thing.

But on this sarcophagus, there are many constraints, and it is impossible to use it.

I can't break my protective clothing, otherwise I only have enough time left to go back and explain the funeral.

That sarcophagus can't be broken either. Hunters hunt to eliminate harm, not to cause trouble.

Once the sarcophagus is broken, the Ukrainian and Russian governments must go crazy. This is the border area between the two countries, so how many lives may have to be filled in.

Moreover, once the sarcophagus is broken, the amount of radiation at the scene will inevitably increase dramatically, and my protective clothing may not matter.

The location of the decisive battle must be very bad, but there is no way.

The things have already been seen, and they can't wait for these two things to rush over and make a move.

Otherwise, he and He Yongchang wouldn't have a big problem, and Wei Xingshan and the unconscious Tang Lingyu would be enough.

We can only solve this matter as soon as possible, just above this sarcophagus.

The leader of the hunting gate dragged Zhuiye backwards, and the sound of footsteps was like thunder as he charged all the way.

Halfway through the run, he suddenly remembered.

Are you stupid

Why should I run over to something that can be shot dead with two arrows

Hey, I'm not used to being under the camera, I'm a little flustered, I forgot about it.

After thinking about it, I was right, the limited-edition backpack was swung up and smashed, and the Qiankun bricks inside were taken out, which barely made sense.

Archery, this round can't be done, the backpack can't have this function.

Besides, stopping to shoot arrows halfway through the run is like taking off your pants and farting, and the leader of the hunting gate can't afford to lose that man.

Wrong is wrong to the end, Lin Shuo had already arrived before the sarcophagus, following the shape of the device, came a "slanted willow".

This is one of the footwork of the Lin family's three best martial arts.

The nearly vertical steep slope, the smooth sarcophagus surface, and the 30-meter-high installation, the chief leader of the hunting gate climbed up in three steps.

Borrowing the strength of his feet in the last step, the man leaped into the air and swung the chasing master in his hand.

At this moment, two hundred meters behind Lin Shuo, Wei Xingshan finally made up his mind.

Before Wei Xingshan was carrying the camera, he was a little hesitant as to whether or not to take pictures of those two hideous things.

This is a live broadcast on the whole network. If this picture is spread, the whole world will be bombarded.

But if he didn't take pictures, why did he come here this time, isn't he the driver and photographer

In the short process of ideological struggle, Lao Wei saw "slanting willows".

This he remembered.

Last year in the Altai Mountains, Lao Lin used this trick when he went back to deal with the rebel after saving himself.

The past was vivid in his mind, and Wei Xingshan slapped his thigh under the agitation of his mind.

Fuck me, I don't even take pictures of this scene, what kind of photographer is I!

The camera rolls, and the whole world sees what happens next:

Lin Shuo was in mid-air, holding Master Chase upside down in his hand, and drew his sword.

Master Chaser was swung out by Lin Shuo with his backhand, from bottom to top.
