Chengdu, in the office.
Chen Nian looked at the report in his hand with satisfaction, and said to Li Xiang beside him:
"This virus lets them play with it, and it really turns out to be fancy."
"If I were to ask, I would never be able to imagine that they would use this method to destroy industrial facilities."
"This is simply a perfect combination of technology and social engineering. If it can really succeed, this attack will definitely be recorded in the history of human information offensive and defensive wars."
"It's so interesting. I feel for the first time that there is fun in doing this kind of thing."
After hearing what Chen Nian said, Li Xiang asked curiously:
"So how interesting is it? Tell me?"
This was of course 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 counting carefully, the number of times is really not that many.
"That's a long story."
Chen Nian leaned back in his chair. He stared at the ceiling and thought for five minutes. He went through the whole process again in his mind. After organizing his words, he said:
"First of all, we need to understand how they launched the attack. We need to know what kind of power station Taichung Electric is."
"I won't sell it to you - putting aside all other factors, Taichung Electric has the clearest label, 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 and began to introduce the concept of supercritical power station 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 there is a critical point in the thermodynamic state in the water vapor cycle. In this state, there is no obvious difference between liquid water and gaseous water."
"Water reaches a critical state at a pressure above 22.1 MPa and a temperature of 374°C, where no additional heat is required to convert water into steam."
"Supercritical thermal power generation has an obvious advantage, that is, the efficiency of the thermodynamic 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 power generation is an efficient solution - but it also requires higher technology and equipment."
“Currently, Alstom’s solutions are the most versatile in the world.”
"This solution uses the GIGATOP series of water-hydrogen-cooled generators, which are their series of generators specially designed 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's words and asked.
"That's right, hydrogen cooling."
"But the question is, is the risk too high for using hydrogen cooling in thermal power plants?"
Chen Nian shook his head and replied:
"The risk is not too high. The generator set is completely isolated from fire sources and oxygen, so accidents generally do not occur. Moreover, compared with ordinary dry gas cooling, its advantages are so great that people cannot Don’t ignore its hidden risks.”
"The heat transfer efficiency of hydrogen is 14 times that of dry air, and its cooling performance will continue 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, when other conditions are exactly the same, the efficiency of a hydrogen-cooled generator set can increase by 2% to 3% - this is already a terrifying range."
"Understood."
Li Xiang nodded, thought for a moment and said:
"So the key to the problem lies in its hydrogen cooling system?"
"I'm just guessing - they want to increase the temperature, break through the supercritical state, and trigger an explosion of hydrogen?"
"How is that possible!"
Chen Nian shook his head in amusement and explained:
"As I said just now, there is no doubt about the safety of this unit. Under the premise of normal operation and normal operation, there is no possibility of accidents."
"However, you must pay attention to the 'prerequisite' I mentioned, that is, normal operation."
"Here, we also need to introduce common sense, that is, any generating set needs to be cleaned and maintained."
"To perform maintenance on GIGATOP, workers must enter the inside of the generating unit - that is, they may come into direct contact with the hydrogen used for cooling."
"However, most of the time, they will shut down the hydrogen generator and confirm that the hydrogen density reaches the standard before performing cleaning operations."
“But everything happens unexpectedly”
"What if the hydrogen used for cooling is not completely eliminated when workers enter the unit?"
"Understood."
Li Xiang suddenly realized.
"What you really want to control is the internal hydrogen generator so that it can continue to produce hydrogen?"
"How is that possible!"
Chen Nian shook his head in confusion.
"The hydrogen generator is the core equipment in the core equipment. It is probably more difficult to attack it than to send people in and drop bombs directly."
"What they want to attack is the hydrogen sensor."
"Modifying hydrogen sensor data, causing technicians to receive incorrect information."
"In this case, the processes of charging carbon dioxide, removing hydrogen, and injecting air will be completely disrupted."
"After they enter the unit, even a small electric spark may cause a violent explosion."
"And this spark doesn't even need to be caused by the worker himself."
At this point, Li Xiang finally had a complete picture of "an accident" in his mind.
After seeing this picture clearly, he had to, like Chen Nian, marvel at the amazing wisdom and creativity of his own technical staff.
They not only need to have a sufficient understanding of how thermal power plants work, but they must also be able to find the most damaging loopholes.
No wonder Chen Nian said that this is a perfect combination of social engineering methods and technical methods - the loopholes of social engineering are added to the loopholes of technology. Isn't this not perfect enough?
"so amazing."
Li Xiang couldn't help but sigh.
"So who came up with it? He's a genius!"
"I have no idea."
Chen Nian shook his head and continued:
"But I guess it would be difficult for you to find out who specifically took the credit."
“This type of genius idea is often born from discussions over and over again.”
"It can be said that everyone involved in this project is a genius."
"Indeed."
Li Xiang nodded solemnly.
But in his heart, he was already looking forward to the explosion that was destined to happen soon.
At the same time, in CALT, the Julang-3 project team combat headquarters.
Zhu Xuejun's face was covered with criss-crossing ravines and black marks left by long-term overloaded work, but her eyes were brighter and firmer than ever before.
Just now, she received the latest report on the Julang-3 project.
Based on the results of the previous DF-41 project, the Julang-3 submarine-launched strategic missile project has made significant progress.
Ground tests including aerodynamics, warhead function, fuze and warhead cooperation, aerodynamics, etc. were all completed. The last warhead aerodynamic shape optimization was completed, and the delivery subsystem, ground equipment subsystem, and missile weapon system tests were also completed successfully. In the end, even the most difficult electromagnetic compatibility test achieved the expected goal with unimaginable efficiency.
And this means that this strategic missile, which has been changed from land-based to sea-based, has completed all ground testing links.
The next step is to conduct a flight test on it to test the overall technical plan and the cooperation of each subsystem.
According to Zhu Xuejun's experience, all domestic missile projects, as long as they can be carried out to this stage, basically have no major problems.
If we evaluate it with a relatively radical attitude, it can even be said that this missile has achieved its expected goals and the project has achieved a staged 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 new high-combustion ramjet engines, new cooling systems, and new fuels, even though the size has shrunk a lot compared to the land-based version of the DF-41, the expected range of this missile still reaches a terrifying 13,000 kilometers.
This means that no matter whether it is launched from any ocean on the earth, it can effectively hit the US mainland.
In terms of strike capabilities, there is no difference between it and the DF-41.
It can also carry 10 separately guided nuclear warheads, and can also drop 120 separately guided nuclear warheads at one time, each with an explosive yield equivalent to 300,000 tons of TNT. It can also ensure strike accuracy within a range of 100 meters.
In one sentence, the size of this missile has been reduced, but its power has not been reduced at all.
Like the DF-41, it is a real "national weapon".
Its birth marks the further improvement of China's nuclear counterattack capabilities, and also marks that China's nuclear deterrence has officially entered the era of land, sea and air trinity from the era of land-based deterrence.
Zhu Xuejun breathed a long sigh of relief. Then, she turned around, faced the people in the war room who were still immersed in their work, and said:
"Everyone."
Everyone in the conference room raised their heads and looked at Zhu Xuejun standing in front.
"I just received the report that the Julang-3 Experimental No. 1 missile has completed all ground tests."
"The experimental results fully met the expected project goals."
"good!!"
As soon as she finished speaking, deafening cheers erupted in the war room.
Even the researcher who had just been resting languidly at the table was now occupied with excitement, with a slightly sickly flushed color appearing on his face.
They have been waiting for this moment for too long. Although it is only a staged victory, it must be said that it is also an important victory.
Everyone was high-fiving and hugging each other, and some were bragging about their group’s contribution to the project.
This is a small bit of vanity that makes people smile, but does not arouse any resentment - or, in other words, it is actually a manifestation of a sense of identity.
Zhu Xuejun allowed everyone to indulge in a rare act of arrogance. She just stood there with a smile on her face, quietly waiting for the scene to calm down.
But what she didn't expect was that before she could even finish the congratulatory and encouraging words she had prepared, the whole scene quickly fell silent.
After a brief celebration, they returned to their posts and returned to their work almost without any pause.
This scene is a bit abrupt, and if placed elsewhere, it could even be said to be strangely embarrassing.
But when it fell into Zhu Xuejun's eyes, her eyes couldn't help but feel a little moist.
Yes, they don't want to stop.
It's like a marathon. When they see their finishing flag and see no one else behind them, excitement is inevitable, but what they have to do next is an even more arduous sprint.
Zhu Xuejun opened her mouth silently. She wanted to say something, but she swallowed it all.
In the end, she only left everyone with a plain sentence:
"Get off work early today and have a good rest."
Then, she turned and left the war room, leading the way home.
A few days later, after months of suppression, a piece of news that had gone through layers of review and discussion exploded in everyone's ears like thunder.
The Julang-3 submarine-launched strategic missile has completed all ground tests and officially entered the aerial test process.
In the future, the existing 094-class nuclear submarines will be fully equipped with Julang-3 missiles to replace the existing Julang-2 missiles.
The implication of this news is self-evident. At such a sensitive moment, it is like a horn that pierces the sky and a flag that is waved at the forefront.
Its appearance is unreasonable - because according to China's general process, such strategic weapons may not be gradually made public until two or three years after they are put into active service.
But it is precisely because of this irrationality that it is so meaningful.
When it was presented to everyone in this way, everyone knew that the situation was about to change dramatically.
The counterattack is about to begin.
Shortly after this news was released, the South China Sea Fleet and the East China Sea Fleet issued announcements announcing that they would organize a large-scale sea test in a certain sea area at 124 degrees east longitude, establish a no-fly zone, and require all passing ships to avoid it.
The fleet, which had been prepared for a long time, immediately took action and gathered in the exercise area on an unprecedented scale...
Several coast guard ships rushed to the sea area where the incident occurred, cruising on the sea with a fearless attitude.
Going one step further, a certain aviation regiment began large-scale transition maneuvers
The huge waves set off by Julang-3 have gradually taken shape.
The first wave of impact will rise on the sea at 125 degrees east longitude.
