This is the sorrow of the layman leading the expert. He doesn't even know how this by-product appears, but he still directs this experiment as the chief engineer.

"Our control rods were inserted too quickly, causing this by-product to develop rapidly," a technician reported. "As per safety regulations, we now need to shut down the reactor."

shutdown?Kiatlov gave the technician a dissatisfied look. If the reactor is shut down, what should we do with this experiment?His experiment result report has already been written. If this experiment is successful, he will go one step further and be transferred to the National Atomic Energy Agency, and he will be promoted to two levels in a row. But now, the experiment is over before it goes on. Then Didn't this experiment fail?He knew the significance of this experiment, which was to verify an emergency response method for nuclear power plants during wartime.

He changed his mind, the control rods were inserted too fast, which led to the claim of by-products, and the power of the nuclear reactor is now dropping too fast, almost one-twentieth of what was expected.

"Then, let's pull out the control rods to increase the power of our reactor. At the same time, the xenon-135 will also be reduced to the normal range?" Kyatlov said.

"Theoretically, yes." The technician could only bite the bullet and answer.

The power was lowered just now, and now it is increased. Everyone present knew that this was a blind command, but they dared not refute it.

"There are only seven control rods left, and the rest are all pulled out."

Hearing this order, the nuclear reactor operator instinctively wanted to refuse. For the safety of the nuclear reactor, at least fifteen control rods must be kept, and now only seven are left. Then, when the reactor needs to be shut down in an emergency, it will become difficult. However, since the chief engineer had already spoken, he complied consciously.

"The power has risen to two hundred megawatts," said the monitor.

"Start the experiment," Kyatlov said.

At this time, it seemed that everything was normal, and there was no unexpected display on the instrument, but they didn't know that, in fact, the nuclear reactor had already started to experience problems.

At [-]:[-], the experiment officially started.

The control personnel turned off the power to the water pump, and the inertia of the turbine generator pushed it forward, reducing the speed of the water flow, and at the same time, the water pump was restarted.

"Successful!" Kyatlov was very satisfied. The successful completion of this experiment will allow him to fill in a heavy sum on his resume here.

No one knows that the reactor at this time has become very unstable, because a series of continuous operations that exceed the safety regulations have increased the steam level of the reactor core, and under normal circumstances, there should be all The coolant, which is liquid water, is correct, and this RBMK graphite reactor is designed with a rather high "cavitation coefficient", which means that when there is no water, only water vapor, the effect of reduced neutron absorption The power of the reactor will increase rapidly. Now that the remaining control rods are not enough to absorb the excess neutrons, the operation of the reactor will gradually become unstable and more dangerous.

Unbeknownst to all the personnel, they were cheering for the success of the experiment.

The experiment lasted for 4 minutes, and the plan was successfully completed, which meant that the experiment was completed.

At this time, the No. [-] reactor is still under maintenance. Therefore, after the experiment is completed, the reactor needs to be shut down.

At this time, Kiatlov issued an order he regretted most in his life: "emergency shutdown."

The reactor can be shut down normally or in an emergency. In fact, Kiatlov was in a hurry to go home, and the normal shutdown only took him a few minutes. However, in normal times, he likes to issue this emergency shutdown. Heap of commands.

The operator pressed the AZ-5 button, which is the rapid emergency defense 5 button. This command is to insert all the control rods, including the control rods that were taken away before.

They didn't know that the Grim Reaper was already beckoning to them, and the countdown had begun, and there were only seven seconds left!

Even for an emergency shutdown, the control rods take 18 to 20 seconds to complete. The difference between the two is the number of control rods inserted at the same time.

With the insertion of the control rods, the hollow part temporarily shifted, and the coolant began to escape. The already unstable reactor suddenly exploded with great enthusiasm, and the power of the reactor began to increase!

The controller, who was about to leave, glanced at the instrument, and suddenly cold sweat broke out on his face, and he immediately shouted: "Oops, the power of the reactor is increasing sharply!"

Another person also shouted loudly: "The pressure of the reactor has exceeded the upper limit!"

Kiatlov's brain went blank for a moment. He knew that if the power exceeds the limit, it means that the core will melt, and if the pressure exceeds the limit, it means that the nuclear reactor will explode!

Although this layman is aware of this now, they have no remedial measures.

Then, they heard a huge explosion.

Three seconds after the emergency shutdown button was pressed, the power of the reactor exceeded five times the specified value, and the inside began to heat up. At that time, the reactor had completely lost control.

Seven seconds later, the power of the reactor rose to ten times the rated power, the fuel rods began to melt, and the steam pressure increased rapidly. Under this pressure, the top of the reactor finally exploded like a balloon!

9Chapter 17 Demons Over Chernobyl

Because of the huge volume of the RBMK-1000 graphite reactor, Soviet designers only used a single protective layer on the outside when designing, which is also the design form of many reactors.

The roof of the blown balloon-like factory building was immediately overturned, and the melted nuclear material inside was blown into the sky like gas, and the nuclear material inside immediately disappeared by 5.00%.And the entire core was exposed to the air, and a blue-white ray shot into the night sky, it was the ray emitted by radioactive elements.

Moreover, as the roof was blown up, the high-temperature graphite blocks in the reactor exposed to the air immediately combined with the oxygen in the air, triggering a graphite fire.Fire spreads and contaminates a wider area with radioactive substances.

When he heard the huge explosion, Kiatlov immediately ran out, sprinted into his car, and immediately drove out of the factory area.

He wants to notify his family and evacuate here immediately. As for other things here, he will not be in charge.

The shrill fire alarm sounded, and Lieutenant Pravik, who was on duty at the second fire station of the nuclear power plant, heard the alarm sound and immediately commanded 28 firefighters including himself to dispatch quickly.

When they arrived at the scene, they were completely stunned. Here, there were fires everywhere, which were caused by the hot remains of the reactor splashing around, as if the magma melted and the volcano erupted.

They knew that the situation at the scene was so critical that they could do nothing about the reactor. In order to avoid greater losses, it was most important to extinguish the rest of the fire.

Reactor No. [-] is next to Reactor No. [-]. The roof of the power generation steam turbine plant next to Reactor No. [-] is paved with asphalt. Now, the fire there is raging and will threaten the No. [-] Reactor which is in operation next to it at any time.

"Quickly, put out the fire on the No. [-] reactor!" Lieutenant Pravik shouted, holding a fire shovel, and climbed onto the roof of the steam turbine.

Following the approaching fire truck, they began to extinguish the flames above. Several team members bravely followed Lieutenant Pravik to the roof. The remains of the reactor fell off the roof of the turbine building.

As officers and soldiers performing firefighting tasks in the nuclear power plant, they naturally know what it means that the No. [-] reactor building was opened and there are internal reactor debris everywhere. , It will cause even greater tragic consequences, and they have no choice.

Lieutenant Pravik fought on the roof for half an hour. He felt dizzy, nauseous, and vomited long ago, but he still persisted.

It wasn't until his eyes turned black and he fell on the roof that he was carried down. At this time, blood was already flowing from his nostrils.

At this time, the radiation intensity of the roof of the steam turbine factory building was 2 roentgens, and the inside of the exploded reactor was 3 roentgens.And as long as 500 roentgens and 5 hours of exposure can cause acute death. (Lieutenant Pravik died two weeks later. Only 28 of the 16 firefighters survived to the 2000th anniversary of the accident, and the rest all died of radiation sickness. It was they who rushed to the scene at the first time to save Reactor No. 12, which worked until December [-], salute to them!) At this time, the people of the small city of Pripyat, three kilometers away from here, are still asleep. Countless radioactive dust enveloped the city they were in. This place was no longer their paradise, but a place of death.

"Doctor, there are emergency patients." In the only hospital in Pripyat, the doctor on duty was suddenly interrupted by a sudden noise.

Hearing the sound, Liev put on his mask urgently and walked outside.

Those people lying on the trolley belonged to firefighters from their clothes, and their skin seemed to be burnt. Bleeding, it should be serious radiation sickness.

Suddenly, he remembered what a good friend told him a few weeks ago. Could it be, did that big event really happen?

"Quick, urgent rescue." Liev said.

Now, almost all people don't know much about radiation. They don't know what harm this kind of radiation will do to themselves, including those firefighters. The clothes on their bodies all have strong radiation .

Before being sent to the emergency room, Liev made a phone call.

On the other end of the phone, Igor Kostin, a good friend of Riev in Kiev, put down the phone heavily. Knowing that the situation was irretrievable, he immediately called back to Baghdad.

An hour after the serious accident at the Chernobyl nuclear power plant, Qusay was woken up from his sleep, and immediately rushed to the office to prepare for the plan that had been prepared.

What does this have to do with Iraq?

This incident has something to do with everyone in the world, whether it is the West or the East, because this is a disaster for all mankind, regardless of national boundaries.

Qusay still remembers that in middle school textbooks, two human nuclear disasters were introduced. The first was the accident that occurred on March 1979, 3 at Unit 28 of the Three Mile Island Nuclear Power Plant in the United States. The core melted, but due to the design There is a strong containment vessel, and the radioactive substances produced by the accident are contained in the containment vessel, without causing any casualties or causing any impact on the environment.The second time was the accident at Unit 2 of the Chernobyl Nuclear Power Plant in the Soviet Union on April 1986, 4. The consequences of this accident were very serious. Until the decades after the incident ended, many people still died They are all suffering from radiation sickness.And just before Qusay crossed, there was another nuclear leak in the island country.
