Chapter 110 I want to dismantle the reactor!
After a night's rest, Ye Zhou re-entered the simulator. This time he did not enter the plot simulation, but turned on the playback of the previous simulation, and began to check the images in the surveillance video frame by frame.

According to his previous judgment, the two groups of engineers who appeared alone in the reactor workshop were the most suspicious, because according to the base's rules and regulations, in order to rule out malicious sabotage or leakage of secrets, the minimum number of people entering the core confidential area is two.

However, after Ye Zhou watched the entire surveillance video in all directions and without any dead ends, he still didn't find any clues.

The first group of engineers was Jinwu’s structural mechanics engineer. They went to the reactor workshop to confirm the reactor’s weight and operating vibration data for the last time, so as to match the fuselage structure they were responsible for and prepare for the subsequent reactor installation.

Their data collection process is very standardized, and it can be seen from the monitoring that each of them has a body recorder, the running indicator light on it is always on, and the work is completely normal from the beginning to the end—— They didn't even get close to the reactor at all, they just collected data on the data collection terminal at the side.

As for the second group, their purpose is even more pure, purely to visit the reactor workshop after obtaining multiple approvals and reviews.

One of them is a senior aviation development expert in China, but he has never worked on a nuclear-powered engine, so out of curiosity, he wanted to take a look at the engine for the last time before it was put on the plane; the other was a senior security officer of the base security department, Eighteen generations of the family's ancestors have all passed strict scrutiny, and there are other restraints that are inconvenient to say, so there is basically no possibility of rebellion.

This guess has almost come to an end here. The trigger for the reactor explosion should not have appeared within a day.

But why?

Ye Zhou's head was getting bigger.

He went back to the first second of the replay, and spent two full hours watching the replay in slow motion, focusing on the last 10 minutes before the explosion.

Likewise, he didn't find anything unusual.

The reactor just stayed there so quietly, and then a blue light flashed, and suddenly it exploded without warning.

Wait, Blu-ray.

Ye Zhou's talent as a planner was suddenly triggered, and he realized that he had been ignoring this blind spot.

He had always subconsciously believed that the blue light before the explosion was Cherenkov radiation in a nuclear reaction, which was a normal phenomenon of a nuclear explosion.

But when I think about it now, I realize that everything is so unreasonable.

Where does the nuclear explosion of a critical accident come from Cherenkov radiation?
This radiation effect can only occur in liquids!

The blue glow in a critical accident is the spectrum emitted by the ionized excited state atoms or molecules in the air when they return to the non-excited state, mainly produced by oxygen and nitrogen.

Electric sparks will be generated in the air, and even light blue lightning will form.

The blue light produced by the so-called Cherenkov radiation is very similar in color to that emitted by ionized air, but this is just a coincidence, and the mechanism of their formation is very different.

So, the only other explanation for this blue light is that something is wrong with the reactor, and the emergency safety system has been involved.

In the case that the test data is all normal, there is something wrong with the reactor?
Unless the system has been tampered with, and can leave a back door.

For safety reasons, the reactor was delivered to the base one month before the simulated scenario. At that time, the reactor had completed its first fuel loading, and the start-up experiment had been completed, so it could be used as long as it was on board.

This kind of operation is to ensure the safety of the base to the greatest extent and shorten the contact time between the base personnel and the nuclear reactor. This is originally a quite humane consideration, but at the same time, it also brings new risks.

Whether it is the Jinwu base or the Nuclear Energy Research Institute that produces nuclear reactors, they are the places with the highest secrecy in the country, but the distance from the research institute to the Jinwu base is absolutely impossible to be completely safe!

According to Ye Zhou's fusion memory, the transportation of this reactor has gone through three sections of transportation: road, railway, and road, and the confidentiality and security of any of these environments are far lower than those inside the base.

What if someone moved their hands at this moment?
In order for the nuclear reactor to explode without any problems during the inspection, there is only one explanation, and the key point is inside the reactor.

The reactor must be opened and the core fully inspected!
He has opened the upper cover of the reactor before and confirmed that there is no problem with the control rod group, so the only possible problems are the two key points of the rod group material and the solution material.

45 minutes is not enough time to open the reactor, find out the internal faults, and eliminate the faults.

But, give it a try anyway.

Ye Zhou exited the playback, reset the thinking programming model according to the experience of the previous simulation, and then immediately entered the simulation.

Running wildly all the way, applying the emergency command authority, declaring the base into a state of emergency, the pre-process is almost the same, but this time, instead of going to the disaster control office, he went straight to the reactor workshop.

"Disaster control, please call all the nuclear physics engineers present to the reactor workshop immediately. I want to dismantle the reactor in the shortest possible time, and the rest of the irrelevant personnel will evacuate immediately!"

Ye Zhou issued the order decisively. The temporary commander of the Disaster Control Office hesitated for a moment, and finally agreed to his request.

Such an order does not violate the basic principle of "maximum protection of personnel safety", nor does it exceed the authority of the emergency command authority.

With a countdown of 38 minutes, Ye Zhou arrived at the reactor workshop. The nuclear physics engineers who arrived one step earlier than him had all put on protective clothing and were starting to dismantle the external structure of the reactor.

This step has not yet touched the core reactor, so the danger is not high. It took less than 6 minutes, all the external structures were removed, and the reactor was exposed to everyone.

This reactor is a miniaturized thorium-based molten salt reactor, which belongs to the fourth generation reactor. In addition to the safety structure of the reactor, the chain reaction realized by the breeder nuclear reaction technology is much safer than the direct use of uranium and plutonium, but relatively , and its structure is more complicated.

After the reactor was exposed, all the engineers present looked at Ye Zhou in dismay. None of them knew what Ye Zhou was going to do next.

Could it be that even the reaction furnace filled with molten salt liquid has to be dismantled?

In that case, the nuclear fuel will be directly exposed to the air, and everyone will be exposed to a huge amount of nuclear radiation, and this radiation is absolutely lethal!
Ye Zhou took a deep breath, and then said:
"Take out a control rod and send it to the material laboratory for spectral analysis to determine the composition of the material!"

"Extract the boric acid filling solution and send it to the chemical laboratory for analysis!"

"In addition, open the emergency storage tank from below and check the condition of the freezing plug!"

Everyone was taken aback by Ye Zhou's words. Even in an emergency, the danger of these three orders seemed too high.

Extraction of the control rods and boric acid fill fluid is fine, but opening the emergency storage tank?

This is the last line of defense of the reactor. If something goes wrong with the core, the high temperature generated by the reaction will burn the freezing plug, and the molten salt liquid carrying nuclear fuel will all flow into the emergency storage tank below to avoid fast neutron radiation. Thereby forcibly stopping the fission reaction.

If the emergency storage tank is opened, it means that they lose their last insurance.

"Ye Gong. Is this too risky?"

Ye Zhou didn't answer, but said firmly:

"dismantle!"

After the words fell, several engineers gritted their teeth, took out the high-temperature cutting machine from the toolbox beside them, walked to the reaction furnace, and quickly cut a small hole in the emergency storage tank.

It is impossible for them to resist orders, but at least they can do it relatively safely.

Just cut a small slit and probe the condition of the freezer plug to keep at least 80% of the functionality of the emergency storage tank.

The time counted down to 15 minutes, and the probe went deep into the storage tank.

The picture was transmitted to the large inspection screen in the workshop through the probe, and with an exclamation, everyone's expressions turned cold.

"Fuck! The freezer plug has been replaced!"
