Hunter of the Forbidden Region Chapter 618: Nuclear accident

Lin Shuo is a heritage hunter and a rural teacher.

Teachers should prepare for lessons, otherwise they will mislead their children. Hunters must also prepare in advance for hunting, otherwise their lives will not be saved.

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

For this Chernobyl business, Lin Shuo will naturally do his homework.

It seems that this is a live show, Lin Shuo took over the live broadcast of goods and sold a limited edition backpack.

In fact, he knew in his heart that it was definitely not that simple.

You can sell goods with just a handsome face. If the business is so good, then any handsome guy in the world can make a fortune.

This is obviously a reason, and Tang Gaojie must have another plan.

Tang Gaojie, Lin Shuo is proud of his father's mouth that can tell the story. That is what he understands.

This is called the origin of family learning. The threshold of the Lin family's nine inches and nine inches, the position of the chief hunter, the other can be put aside, first of all, you have to know people.

Knowing people is not clear, which is more serious than being able to withstand impotence.

So Lin Leshan had already broken up and chewed the characters in the names of the characters in the gates of the rivers and lakes, what kind of industry, what was able to endure, and what characteristics, and gave it to his son in one bite.

Tang Gaojie is a few years older than the Four Hunter Masters 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 responsible for this area in the middle of Sichuan.

The Tang family in Shuzhong, this is the long-established seven-inch family of Hunter Gate. There are many capable people. When Tang Gaojie came out of Yicheng, he had a very high reputation.

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

At that time, Lin Leshan was a fledgling young man, with the reputation of his father, Lin Chaodong, who had the worst reputation in the Lin family.

But when the business was done this time, Lin Leshan and Lin Shuo didn't elaborate. In the end, when the two were compared, Lin Leshan was far superior.

At that time, the team was more than the two of them, and the news spread, and soon spread through the door, and the reputation of the two was reversed.

Tang Gaojie is not a narrow-minded person. He didn't anger Lin Leshan about this, but he didn't feel like it at all.

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 30 years later, he will not be the opponent of the Su family brothers. The consequences of encountering the future gambling **** that time can be imagined.

He tortured the Lin family heirs at the gaming table, Tang Gaojie laughed and went out, and then went to the United States alone.

This is almost forty years ago.

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

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

Live sales, **** hell if he is interested in such a mess.

Moreover, he was somewhat unconvinced with the Lin family heirs.

So for this trade, Lin Shuo must do his homework.

If you don't prepare enough beforehand, you may lose your father's person later.

Sure enough, there is something here.

The current two-headed ferociousness might be the surprise that Tang Gaojie prepared for himself.

Lin Shuo has dealt with this surprise. It is a surprise. If it is not handled well, it will be the panic of the whole world.

Chernobyl, this place is so unusual.

Especially the place where these two awkward ends are currently waiting, which is even more unusual.

This is the fourth unit of the Chernobyl nuclear power plant.

The nuclear reactor where the accident happened 20 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 the fission energy is used 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, so let's not mention it.

And boiling water, this is simple, it is boiling water.

The circulating cooling water enters the reactor and is boiled before being pumped out. The steam generated by the boiling water is used to drive the power generation turbine.

At the time, the pumping water pump was to be tested here. This pump is required to continue to work to pump out hot water when the nuclear reactor is temporarily not providing energy.

This pumping hot water is very important, otherwise the accumulation of high temperature is very dangerous.

The power supply to the water pump is done by a diesel generator so that the water pump can continue to work.

It takes a minute for the diesel generator to start, and the heat accumulation in this minute is enough, and it's easy to get into trouble.

The engineer had a new idea, thinking that it could use power generation turbines driven by power plant steam.

The nuclear reactor is temporarily not providing energy at this time, but the turbine has inertia, and the power of the water pump this minute is empty, allowing the turbine to fill in inertia.

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

Three experiments failed, and by the fourth time, something went wrong.

April 26, 1986, just two months ago was exactly 20 years ago.

At that time, a small power station next to Kiev, the capital of Ukraine, suddenly shut down, resulting in a shortage of electricity in the capital.

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 is not using much electricity.

The factory manager agreed at the time, but this caused two problems.

First, according to the factory's schedule, the technical backbones are all on duty during the day, and on duty at night are young operators who have just started work.

So this complex test task falls on this group of young heads.

At that time, the operator was twenty-five years old and had only been at work for four months. He was stupefied to do this kind of work.

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

The reactor was in the daytime on this day, because it was going to be tested before, and then it was suddenly delayed and kept running at half power.

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

Xenon 135 has a very high concentration in the early hours of the night.

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

The test began in the middle of the night, and the power of the nuclear reactor continued to decrease, and the high concentration of Xenon 135 began to be a demon.

The power of the nuclear reaction fell indefinitely and rapidly.

The matter ends here, and there is still some help.

Shut down the reactor for twenty-four hours, Xenon 135 itself will decay and disappear automatically.

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

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

Now it's dead.

Knowing that the next thing to do is to violate the 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 opposite of the previous one. The purpose is to increase the power of the reactor a little bit so as to simulate the normal operation of the reactor as much as possible.

At that time, the concentration of xenon 135 inside the reactor was still very high, hindering the nuclear reaction, and the power could not be increased.

The manual operation side is actually full.

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

When water boils, bubbles will form.

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 nuclear reactions began to decline.

This decline is not linear, but exponential.

When the suppression drops, the power of the nuclear reactor starts to climb rapidly and soon becomes uncontrollable.

The acting chief engineer panicked at this time and quickly ordered the nuclear reactor to be shut down.

But this thing is not as simple as a power switch, you can turn it off when you turn it off.

At that time, the switch of this nuclear reactor device was 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, and graphite promotes nuclear reactions.

The principle of this switch is that a rod is inserted in the reactor, and the power of the reactor is controlled by contacting the upper half of boron and the lower half of graphite with the reaction materials respectively.

In the beginning, the acting chief engineer wanted to increase the power, so the twenty-five-year-old young operator pulled the control rod up to allow the lower half of the graphite to more contact the reactants, that is, uranium 235 and uranium. 238, to promote nuclear reactions.

The guy has no experience, thinking that the more you pull up, the greater the power, so the operation is full, and the two hundred and five sticks are pulled out manually.

So even the lower half of the graphite was pulled out, all hanging over the reaction material.

At this moment, the acting chief engineer said to shut down the nuclear reactor quickly, and the guy controlled the stick to stick it down.

For this insert, the lower half of the graphite is the first to contact the reaction material, which promotes the reaction.

This is called adding fuel to the fire.

The reaction increased sharply to tens of gigawatts, and the water was instantly vaporized, and the resulting pressure distorted the reactor.

The control rod is stuck in it and cannot be inserted further. The lower part of the graphite is stuck in the middle of the reactor, and the upper part cannot be removed.

So when you add up inside and out, it's completely out of control.

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

The reactor core melted instantly at ultra-high temperatures, and the 1,400-ton reactor roof was thrown into the air by a steam explosion.

So oxygen enters the reactor, and all combustible materials deflagrate rapidly at high temperatures.

The violent explosion caused the graphite wrapped in radioactive materials to fly around.

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

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

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

The human body's genes and the genetic information carried by DNA are molecular information, which will be smashed.

The genetic information is destroyed, the body's metabolism is no longer good, and the cells cannot be replaced, so it chronically dies.

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

This incident was the largest nuclear accident in human history and was designated as the highest level 7 disaster event.

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

How did the Soviet government rescue the disaster afterwards? It was an epic operation. Lin Shuo was very moved by seeing it in the Nordic library.

In the end, after thousands of lives were sacrificed and the lifespan of tens of thousands of rescuers were discounted, all radioactive materials were finally sealed up.

A giant sarcophagus is sealed up for these materials, which is covered by the No. 4 nuclear device.

And this sarcophagus has a lifespan, about thirty years.

Thirty years later, the sarcophagus itself will become a radioactive source.

Now twenty years have passed, and this sarcophagus has ten years left to be used. Within ten years, a larger sarcophagus will be available.

The current two scorpions are just above the sarcophagus, standing with one end and lying on the other.

……

These two things don't take nuclear radiation so seriously. Of course, they are a kind of ignorance as ignorant creatures.

There is no need for Lin Shuo to hunt them, the life of these two things will not exceed one week in the future.

But now the two groups of horses and horses ran into each other, you saw me, and I saw you too. This is a narrow encounter.

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

The place where Lin Shuo chose to meet these two beasts and alien species was on the top of the sarcophagus.

If the two-headed ferocious is left in another place, Lin Shuo will not ask too much questions. The Lin family descendants have hunting experience.

But on this sarcophagus, there are too many constraints.

My own protective suit can't be broken, otherwise I will only have enough time to go back and explain the funeral.

The sarcophagus can't be broken either. Hunters are here to kill harm, not to cause trouble.

As soon as the sarcophagus was broken, the Ukrainian and Russian governments had to go crazy. This is the border area between the two countries. It may be how many lives must be filled in.

Furthermore, once the sarcophagus is broken, the amount of radiation at the scene will inevitably increase drastically, and I might be fine with my protective suit.

The location of the final battle must be terrible, but there is no way.

The thing has already been seen, so you can't wait for these two things to rush over and do it.

Otherwise, there is no big problem between himself and He Yongchang. Wei Xingshan and Tang Lingyu, who is in a coma, will be choking.

We can only resolve this issue as soon as possible, right on top of this sarcophagus.

The chief hunter dragged down and chased the Lord, and as he charged all the way, his footsteps sounded like rushing thunder.

In the middle of running, he suddenly remembered.

Are you stupid?

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

Hey, I didn't feel comfortable with being photographed by the camera. I was a little flustered and I forgot about it.

It's right to think about it again. The limited edition backpack is smashed, and the universe bricks inside are taken out again. It barely makes sense.

Archery, this is too round, and backpacks can't have this kind of function.

Furthermore, halfway through to stop shooting arrows, this is taking off your pants and farting, the chief hunter can't afford to lose that person.

The wrong thing is to the end. Lin Shuoren has already reached the sarcophagus, and following the appearance of the device, there is an "inclined willow".

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

The nearly vertical steep slope, the smooth surface of the sarcophagus, and the 30-meter-high installation, the chief hunter gate "Da", "Da" and "Da" went up in three steps.

With the help of the last step, the person leaped into the air and raised his hand to chase him.

……

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

Before, Wei Xingshan was carrying the camera, and he was a little hesitant whether to take pictures of the two ugly things.

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

But if you don’t shoot~IndoMTL.com~ Why did you come this trip? Isn’t it the driver and photographer?

During the brief ideological struggle, Old Wei saw the "slant cutting willow".

He remembers this.

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

The past is vivid in my eyes, and Wei Xingshan slapped his thigh with agitated mind.

I'm going to fucking, and I don't shoot this picture. Be a photographer!

The camera turned, and the whole world saw what happened next:

Lin Shuoren is in the air, holding his hand upside down to chase his master, in a sword-drawing style.

Lin Shuo used his backhand to chase the Lord, pulling it out diagonally from bottom to top.
