Spark

in the office.

Chen Nian looked at the report in his hand with satisfaction, and said to Li Xiang beside him:

This virus let them play, and they really played well.

Let me come, I guess I can't think of anything. They will use this method to achieve the destruction of industrial facilities.

This is simply the perfect combination of technology and social engineering. If it is really successful, this attack will definitely be recorded in the annals of human information offensive and defensive warfare.

It's so interesting. For the first time, I feel that doing this kind of thing is also fun.

Hearing Chen Nian's words, Li Xiang asked curiously:

So how interesting is it? Tell me?

Of course, this was not the first time he saw such an expression on Chen Nian's face. He still remembered that when Wang Jiancheng took out Yujing AI, his reaction was similar.

But if you count carefully, the number of times is really not much.

That's a long story.

Chen Nian leaned back on the chair, stared at the ceiling, thought for a full five minutes, went through the whole process in his mind again, organized his words, and then said:

First of all, we need to understand how they launched the attack. We need to know what kind of power station Taichung Power is.

I'm not going to tell you anything - apart from all other factors, Taichung Power has one of the clearest labels, that is, it is a supercritical thermal power station.

Supercritical power station? What do you mean?

Chen Nian sat up straight again, then pulled a piece of paper casually, and began to introduce the concept of supercritical power plants to Li Xiang.

The so-called 'supercritical' refers to the pressure and temperature conditions of the steam produced by the boiler.

We all know that in the water vapor cycle there is a critical point of a thermodynamic state where there is no clear distinction between liquid water and gaseous water.

Water reaches a critical state at a pressure above 22.1 MPa and a temperature of 374°C. Simply put, no additional heat is required in this state to convert water to steam.

Supercritical thermal power generation has an obvious advantage, that is, the efficiency of the thermal cycle can reach between 40% and 42%, while in contrast, the efficiency of the subcritical power plant cycle is only 36% to 37%.

So, supercritical state power generation is an efficient solution - but relatively, it will have higher requirements for technology and equipment.

Currently speaking, the most versatile solution in the world is the Alstom solution.

This solution uses the GIGATOP series of water-hydrogen-cooled generators, which is their series of generators specially built for coal-fired power plants.

This generator has a more prominent feature, that is, its stator winding is water-cooled, but the rotor and stator core are directly cooled by hydrogen.

Wait a minute, hydrogen cooling? Direct cooling with hydrogen gas?

Li Xiang subconsciously interrupted Chen Nian and asked.

That's right, hydrogen cooling.

But the question is, is the risk too high to use hydrogen cooling in thermal power stations?

Chen Nian shook his head and replied:

There is not too much risk. The part of the generator set is completely isolated from fire and oxygen, and generally there will be no accidents. Moreover, compared with ordinary dry gas cooling, its advantages are so great that people have to Don't ignore the hidden risks.

Hydrogen is 14 times more efficient at transferring heat than dry air, and its cooling performance continues to increase as the pressure increases.

At the same time, the density of hydrogen is extremely low, which brings extremely superior low wind resistance performance.

According to calculations, using a hydrogen-cooled generator set, under the condition that other conditions are exactly the same, the efficiency can increase by 2% to 3%-this is already a terrifying range.

Understood.

Li Xiang nodded and said after a little thought:

So the key to the problem lies in its hydrogen cooling system?

I'll take a random guess—they want to increase the temperature, break through the supercritical state, and trigger an explosion of hydrogen gas?

How is that possible!

Chen Nian shook his head amusedly, and explained:

As I said just now, the safety of this unit is beyond doubt. Under the premise of normal operation and normal operation, there is no possibility of accidents at all.

However, you have to pay attention to the 'premise' I said, that is, normal operation.

Here, we also need to introduce a common sense, that is, any set of generator sets needs to be cleaned and maintained.

To perform maintenance on the GIGATOP, workers would have to go inside the generator set—that is, they might come into direct contact with the hydrogen used for cooling.

However, most of the time, they will shut down the hydrogen generator and make sure the hydrogen density is up to standard before performing the cleanup operation.

But everything happens by accident

What if, when the workers enter the unit, the hydrogen used for cooling is not exhausted?

Understood.

Li Xiang suddenly realized.

What you really want to control is the internal hydrogen generator, so that it can continuously produce hydrogen?

How is that possible!

Chen Nian shook his head dumbfounded.

The hydrogen generator is the core equipment in the core equipment. It may be more difficult to attack it than sending people in and throwing bombs.

What they want to attack is the hydrogen sensor.

Modify the data of the hydrogen sensor, so that the technician received the wrong information.

In this case, the process of filling carbon dioxide, degassing hydrogen, and injecting air will be completely disordered.

After they enter the unit, even a small electric spark may cause a violent explosion.

And this electric spark doesn't even need to be caused by the workers themselves.

Speaking of this, Li Xiang finally had a complete picture of an accident in his mind.

And after seeing this picture clearly, he had to, like Chen Nian, marvel at the amazing wisdom and creativity of his technicians.

Not only do they need to have a good understanding of how thermal power plants work, they must also be able to find the most lethal loopholes.

No wonder Chen Nian said that this is a perfect combination of social engineering methods and technical methods - the loopholes of social workers, combined with the loopholes of technology, isn't it perfect?

so amazing.

Li Xiang couldn't help sighing.

So who came up with it? It's a talent!

I have no idea.

Chen Nian shook his head and continued:

However, I guess it will be very difficult for you to find out who is responsible for it.

This kind of genius idea is often born in discussions again and again.

It can be said that everyone involved in this project is a genius.

Indeed.

Li Xiang nodded solemnly.

But in his heart, he has already begun to look forward to

At the same time, within CALT, the operational command of the JL-3 project team.

Zhu Xuejun's face is full of vertical and horizontal grooves and black and blue marks left by long-term overload work, but her eyes are bright and firm like never before.

Just now, she received the latest report on the Julang-3 project.

According to the results of the previous DF-41 project, the JL-3 submarine-launched strategic missile project has made significant progress.

The ground tests including aerodynamics, warhead function, fuze and warhead coordination, aerodynamics, etc. have all been completed. The final aerodynamic shape optimization of the warhead has been completed, and the tests of the delivery subsystem, ground equipment subsystem, and missile weapon system have also been completed successfully. In the end, even the most difficult electromagnetic compatibility test has achieved the expected goal with unimaginable efficiency.

And this also means that this strategic missile, which has changed from land-based to sea-based, has completed all the ground tests.

The next step is to conduct a flight test on it to test the overall technical plan and the coordination of each subsystem.

According to Zhu Xuejun's experience, as long as all domestic missile projects can be carried out to this point, there are basically no major problems.

If it is evaluated with a relatively radical attitude, it can even be said that this missile has reached the expected goal, and the project has achieved a phased victory.

Standing in front of the big screen in the command room, Zhu Xuejun looked at the latest performance parameters in the report for the last time.

With the support of the new high-combustion ramjet engine, new cooling system, and new fuel, even though the size has shrunk a lot compared to the land-based version of the DF-41, the expected range of such a missile still reaches a terrifying 13,000 kilometers.

In other words, no matter if it is launched from any ocean on the earth, it can effectively strike the US mainland.

In terms of strike capability, there is no difference between it and the DF-41.

It can also carry 10 separate guided nuclear warheads, and can also throw 120 separate guided nuclear warheads with an explosive equivalent of 300,000 tons of TNT at a time, and can also ensure that the strike accuracy is within 100 meters.

In a word, the size of this missile has been reduced, but its power has not been reduced at all.

Like DF-41, it is a real country's most important weapon.

Its birth marks the further improvement of nuclear counterattack capabilities, and also marks the formal entry into the trinity era of land, sea and air from the era of land-based deterrence.

Commander Zhu Xuejun let out a long sigh of relief, then she turned around, faced the people in the war room who were still working hard, and said:

Everyone.

Everyone in the conference room raised their heads and looked at Zhu Xuejun standing in front of him.

I just received a report that the Julang-3 experiment No. 1 projectile has completed all ground tests.

The experimental results fully met the expected project goals.

good!!

As soon as her words fell, deafening cheers erupted in the war room.

Even the researcher, who was resting at the table sluggishly just now, was excitedly occupied at this moment, with a slightly sickly flushed color on his face.

They had waited for this moment for too long. Although it was only a phased victory, it had to be said that it was also a decisive victory.

Everyone was high-fiving and hugging each other, and some were bragging about their team's contribution to the project.

It's a small, knowing smile, but it doesn't arouse any repulsive vanity—or, in fact, it is also a manifestation of a sense of identity.

Zhu Xuejun let everyone's rare presumptuousness, she just stood there with a smile on her face, quietly waiting for the scene to calm down.

However, what she didn't expect was that the whole scene quickly fell silent before she finished the few congratulatory and encouraging words she had prepared.

After a short celebration, they returned to their posts, almost without any stagnation, and devoted themselves to their work again.

This scene is a bit abrupt, if it is placed in other places, it can even be said to be a bit weird and embarrassing.

But when it fell into Zhu Xuejun's eyes, her eye sockets couldn't help but get a little moist.

Yes, they are not willing to stop.

This is like a marathon. When they see their flag at the finish line and see that there is no one behind them, excitement is inevitable, but the next thing to do is a more arduous sprint.

Zhu Xuejun opened his mouth silently, she wanted to say something, but swallowed it all.

In the end, she only left everyone with a plain sentence:

Get off work early today and rest well.

Afterwards, she turned and left the war room, leading the way home.

A few days later, after several months of repression, a piece of news that went through layers of review and discussion exploded in everyone's ears like a thunderbolt.

The Julang-3 submarine-launched strategic missile has completed all the ground tests and officially transferred to the air test process.

In the future, the 094-class nuclear submarines in active service will be fully equipped with Julang-3 to replace the Julang-2 missiles currently in service.

The implied meaning of this news is self-evident. At such a sensitive moment, it is like a horn piercing through the sky, and it is also like a flag being waved at the forefront.

Its appearance is unreasonable --- because according to the general process, this type of strategic-level weapon may even be gradually released after two or three years of being put into active service.

But it is precisely because of this unreasonableness that it is so meaningful.

When it was presented in front of everyone in this way, everyone knew that the situation was about to change drastically.

The counterattack is about to start.

The huge wave created by Julang-3 has gradually taken shape.

And the first wave of impact will rise on the sea at 125 degrees east longitude.
