Chapter 618: Nuclear Accident
Lin Shuo is a heritage hunter and a rural teacher.
Teachers must prepare for class, otherwise they will mislead people's children, and hunters must also prepare in advance for hunting, otherwise their lives will be lost.
The preparation of the hunter is a matter of life and death, and the more meticulous it is, the less meticulous it is.
In this Chernobyl business, Lin Shuo will naturally do his homework.
It seems that this is a live broadcast show, and Lin Shuo took over the live broadcast to bring goods, and sold a limited edition backpack.
But in fact, he knew in his heart that it must not be so simple.
With just a handsome face, you can sell the goods. If the business is so easy to do, then all handsome guys in the world can make a fortune.
This is obviously a reason, Tang Gaojie must have other plans.
Tang Gaojie is a person, Lin Shuo is proud of his old man's storytelling mouth, which is understood.
This is called the origin of family learning, the threshold of the Lin family's nine inches and nine, the position of the head of the hunting gate, and the other abilities are put aside, and they have to know people first.
Knowing people is a greater sin than being incapacitated.
Therefore, the character name in the rivers and lakes, what industry, what ability, what temperament, Lin Leshan had already broken and chewed, and fed it to his son in one mouthful.
Tang Gaojie is a few years older than the four heroes of the hunting door led by Lin Leshan, and he was originally a romantic figure of their generation.
Since the Su family moved to the foot of Kunlun Mountain during the Northern Song Dynasty, the Tang family is responsible for this place in Shuzhong, Sichuan.
The Tang family in Shuzhong, this is the time-honored seven-inch family of Liemen, capable of producing many people, Tang Gaojie was once highly rated when he came out of the mountain.
Until one time, he teamed up with Lin Shuo's father and made a deal.
At that time, Lin Leshan was a fledgling, and he had the reputation of his old man Lin Chaodong, which was the worst time for the Lin family.
But after this trip was done, Lin Leshan and Lin Shuo didn't talk about it in detail, in short, in the end, compared with the two, Lin Leshan was far better.
At that time, there were more than the two of them in the team, and the news spread out, and soon spread all over the door, and the reputation of the two was reversed.
Tang Gaojie is not a narrow-minded person, he didn't anger Lin Leshan in this matter, but he didn't feel good in his heart.
He ran over and had a drink with Lin Leshan, and then played cards with Lin Leshan all night.
Lin Leshan's card skills have always been stinky, and he is not the opponent of the Su brothers after 30 years.
abused the heirs of the Lin family at the gambling table, Tang Gaojie laughed and went out, and then went to the United States alone.
That was nearly 40 years ago.
He made his career in the United States and moved the entire Tang family in Shuzhong to North America, which is a later story, in short, Tang Gaojie is a high-minded and arrogant lord who is unwilling to be subordinate.
He and Miao Guangqi are similar in temperament, and they like to do things bigger.
Live broadcast to sell goods, this kind of is only if he is interested in it.
And he is still a little unconvinced by the heirs of the Lin family.
So for this trip, Lin Shuo must do his homework.
If you don't prepare well in advance, you may have to lose your old man.
Sure enough, there's something here.
The current two-headed hideousness may be the surprise that Tang Gaojie prepared for himself.
This surprise, Lin Shuo handled it well, it was a surprise, if it was not handled well, it would be the horror of the whole world.
Chernobyl, this place is so unusual.
Especially the place where these two heads are waiting at the moment, it is even more unusual.
This is unit number four of the Chernobyl nuclear power plant.
The nuclear reactor that crashed twenty years ago is here.
The general principle of a nuclear reactor is to use the fission of low-concentration uranium-235 to produce energy, which is controlled, 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 complex to mention.
And boiling water, this is simple, is to boil water.
The circulating cooling water enters the reactor and is then pumped out, and the steam generated by the boiling water is used to drive the power turbine.
At that time, a pumping pump was being tested here, which required that the reactor could continue to work and pump hot water out when the reactor was temporarily not providing energy.
This hot water is critical, otherwise the high temperature will accumulate dangerously.
The power supply to the pump was done by a diesel generator so that the pump could 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 it is easy to have an accident.
Engineers had the idea of using steam-powered power turbines in power plants.
The nuclear reactor is temporarily unable to provide energy at this time, but the turbine has inertia, and the power vacancy of the water pump for this minute can make the turbine inertia fill.
The idea was wonderful, but at the time it was a technical gap, and there were problems in practice.
Three experiments failed, and by the fourth time, something had happened.
April 26, 1986, was exactly 20 years ago.
At that time, a small power station next to Kyiv, the capital of Ukraine, was suddenly shut down, causing a shortage of electricity in the capital.
The nuclear power plant test is to shut down the reactor and stop generating electricity.
The power bureau asked the nuclear power plant not to conduct the fourth test during the day, but to move it to the middle of the night, when the city does not use much electricity.
The factory director agreed at the time, but this brought two problems.
First, according to the factory's schedule, the technical backbone is the daytime shift, and the night duty is some young operators who have just come to work.
So this complicated test task fell on the heads of this group of young people.
At that time, the operator, who was twenty-five years old and had only been on the job for four months, was confused to do this kind of work.
The second problem is the technical problems inside the nuclear reactor.
During the day, the reactor was scheduled to be tested, and then it was abruptly delayed, and it has been running at half power.
Running at half power causes the reactor to accumulate large amounts of iodine-135 over several years, which constantly decay into xenon-135.
By the early hours of the night, the concentration of xenon-135 was extremely high.
Xenon-135 has the effect of absorbing neutrons and hindering nuclear reactions.
At the beginning of the midnight test, the power of the nuclear reactor continued to be lowered, and the high concentration of xenon-135 began to bewitch.
The power of the nuclear reaction is falling hopelessly.
That's the end of the matter, there is still salvation.
After shutting down the reactor for twenty-four hours, Xenon-135 itself will decay and disappear on its own.
But shutting down the reactor meant that the fourth experiment was a complete failure.
This result was obviously unacceptable to the acting chief engineer at that time.
And so began to die.
Knowing that the next step would be a safety violation, 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, and the purpose is to pull the reactor power up a little bit in order to simulate the normal operation of the reactor as much as possible.
However, 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.
As for the manual operation, the control is actually full.
Then the pump started to work, and the water at the bottom was gradually pumped out, but not so quickly, and the heat accumulated before the circulating water system, which still caused the water remaining in the reactor to boil.
When water boils, bubbles are formed.
Water has an absorption effect on neutrons and can inhibit nuclear reactions.
Once bubbles are generated, then this inhibition 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 effect of the two substances that have inhibition of the nuclear reaction begins to decline.
This decline is not linear, but exponential.
As the inhibition decreases, the power of the nuclear reactor begins to rise rapidly, and it 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, it is turned 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 the rod is inserted in the reactor, and the power of the reactor is controlled by the contact between the upper half of boron and the lower half of the graphite and the reactive substance.
At first, the acting chief engineer wanted to increase the power, so the young operator, who was twenty-five, pulled the control rod up to let the lower half of the graphite touch more with the reactive substances, that is, uranium-235 and uranium-238, to promote the nuclear reaction.
The young man had no experience, thinking that the more he pulled up, the more power he had, so he operated to the full, and manually controlled all the two hundred and five sticks to pull out.
As a result, even the lower half of the graphite was pulled out and hung over the reactive substance.
At this time, the acting chief engineer said to shut down the nuclear reactor immediately, and the young man controlled the rod to be inserted down.
This insertion, which first touches the reactive substance, is the lower half of the graphite, which promotes the reaction.
It's called adding fuel to fire.
The reaction increased dramatically to tens of billions of watts, the water was vaporized instantly, and the resulting pressure distorted the reactor.
The control rod was stuck in it and could not be inserted any further, and the lower half of the graphite was stuck in the middle of the reactor, and the upper half of the graphite could not be inserted.
So the inside and the outside add up, and this is completely out of control.
The final meter reading was 33 billion watts, ten times the normal power.
The reactor core melted down instantaneously at ultra-high temperatures, and the 1,400-ton reactor roof was thrown into the air by a steam explosion.
As a result, oxygen enters the reactor, and everything that can be burned quickly deflagrates at high temperatures.
The violent explosion sent the graphite encased in radioactive material flying in all directions.
In the sky above the nuclear power plant, a dark blue pillar of light appeared.
That's the spectrum that atoms in the air absorb high-energy rays, become excited, and then return to the 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 genetic information carried by the human body's genes and DNA, that is, molecular information, will be smashed.
When the genetic information is destroyed, the body's metabolism will not work, and the cells will not be able to replace, so it will die slowly.
So once you are exposed to high-intensity nuclear radiation, there is no cure.
This incident, the largest nuclear accident in human history, was designated as the highest seventh-level catastrophic event.
The power of all radioactive materials is equivalent to 140 atomic bombs to Hiroshima.
How the Soviet government at that time rescued the disaster afterwards was an epic operation, and Lin Shuo was very moved to see it in the Nordic library.
In short, after sacrificing thousands of lives and discounting the lives of tens of thousands of rescue personnel, all the radioactive material was finally sealed.
The material was sealed in a giant sarcophagus that was placed on top of Nuclear Device 4.
And this sarcophagus has a lifespan, about thirty years.
Thirty years later, the sarcophagus itself would become a radioactive source.
Now twenty years later, there are still ten years left in this sarcophagus to use, and a bigger sarcophagus will have to be brought in ten years.
And the current two-headed hideous is on top of the sarcophagus, one standing and the other lying.
......
These two things don't take nuclear radiation seriously, of course, because of their ignorance as ignorant creatures.
Without Lin Shuo hunting them, these two things would not live for more than a week in the future.
But now two groups of people collide, you see me, I see you, this is a narrow road meeting.
It won't take that long to see each other in life and death at this point.
And the place where Lin Shuo chose to meet the life and death of these two fierce beasts was on the sarcophagus.
If the two heads are left in other places, Lin Shuo doesn't ask himself a big question, this thing is the heir of the Lin family has hunting experience.
But on this sarcophagus, there are so many places of constraint that I can't show my ability.
I can't tear this protective suit, otherwise the rest of my time will only be enough to go back and explain what happened.
The sarcophagus can't be broken, hunters hunt to eliminate harm, not to cause trouble.
As soon as the sarcophagus is broken, the Ukrainian and Russian governments will have to go crazy, this is the border area between the two countries, and it is impossible to tell how many lives will have to be filled in.
And once the sarcophagus is broken, the amount of radiation at the scene will inevitably increase dramatically, and his protective clothing may be fine.
The location of the decisive battle must have been terrible, but it can't be helped.
The thing has already been seen, and we can't wait for these two things to rush over and do it.
Otherwise, it is not a big problem for himself and He Yongchang, Wei Xingshan and Tang Lingyu who are in a coma are enough to choke.
This matter can only be solved as soon as possible, right on top of this sarcophagus.
The head of the hunting gate dragged the chasing master, and under the charge all the way, the footsteps were like thunder.
Halfway through the run, he suddenly remembered.
Are you stupid?
What can be killed with two arrows to chase the master, why should he run over?
Wow, I don't feel comfortable being illuminated by the camera, and people are a little panicked and forget about this stubble.
After thinking about it, it was right, the limited edition backpack was picked up and smashed, and the Qiankun bricks inside were taken out again, which was barely reasonable.
Archery, this is not round, and the backpack cannot have this function.
Besides, if you stop shooting arrows halfway through, this is taking off your pants and farting, and the head of the hunting gate can't afford to lose that person.
Wrong is wrong in the end, Lin Shuo has already arrived in front of the sarcophagus, and following the shape of the device, there is a "diagonal willow".
This is one of the footwork of the Lin family's three unique martial arts.
With a nearly vertical steep slope, a smooth sarcophagus face, and a thirty-meter-high device, the head of the hunting gate went up in three steps.
In the last step, he borrowed the strength of his feet, and the person jumped in the air and picked up the chasing master in his hand.
......
At this time, two hundred meters behind Lin Shuo, Wei Xingshan finally made up his mind.
Wei Xingshan was carrying the camera before, and he was a little hesitant to shoot the two-headed thing or not.
This is a live broadcast on the whole network, and if this picture is spread, the whole world will be fried.
But if you don't shoot, why are you here this time, isn't it the driver and photographer?
In the course of a short ideological struggle, Lao Wei saw the "oblique willow".
This, he remembers.
Last year in the Altai Mountains, Lao Lin used this trick when he went back to deal with the barge after saving himself.
The past was vivid, and under the agitation of his heart, Wei Xingshan slapped his thigh.
I'll fuck it, I won't shoot this picture, what kind of photographer!
The camera turned, and the world saw what happened next:
Lin Shuo was in mid-air, holding the chaser upside down in his hand, and came to a knife drawing style.
Chasing Ye was swept out diagonally from bottom to top by Lin Shuo with his backhand.
