   Chapter 375 Open Class

  ZZ City, Jiangbei Province.

  As the temperature gets colder, the belated first snow finally floats in the air.

  Unconsciously, the transformation and upgrade of the EAST device has been over for a month and a half.

  However, so far, the engineers’ progress is still at the stage of equipment disassembly. After all, every action of this kind of precision large-scale equipment needs to be professionally analyzed and evaluated, and there must be no mistakes in the sequence. The disassembled parts also need to be numbered and specially stored in accordance with regulations.

  The progress cannot be fast.

  Not to mention that Zhong Weijian and others have received instructions from Kang Chi to delay the progress of this upgrade as much as possible.

  At least within three months, they cannot really enter the part replacement stage.

Although Zhong Weijian chose to support Kang Chi at the beginning, he was inevitably prone to anxiety after being idle for a long time, especially since Kang Chi had never held a normal technical seminar since he became the chief engineer of China’s controlled nuclear fusion.

  Everyone was like a sheep being herded. Except for the engineers responsible for the disassembly and assembly of the equipment, everyone else was basically idle.

  It seemed that Kang Chi’s appointment was just to postpone the research on controlled nuclear fusion…

  After Zhong Weijian put the academic journal in his hand on the table, he looked up at the snowflakes floating outside the window and couldn’t help lighting another cigarette.

  ”Old Zhong, Professor Cheng is looking for you!” The voice of his wife suddenly came from outside the study.

Zhong Weijian got up quickly, walked to the living room and greeted Cheng Tao with a smile: “I was just thinking about going to your house for a meal, but I didn’t expect you to be quicker.”

  ”You still have the mind to eat?” Cheng Tao shook his head helplessly, “Do you know what happened just now?”

  Seeing Cheng Tao’s serious expression, Zhong Weijian couldn’t help but asked nervously: “What happened?”

  ”This morning, Kang Chi gave an open class to students at Su Province University.”

  ”Open class?”

  ”Yes, and it’s about controlled nuclear fusion… a popular science open class.”

  ”What’s the problem with this?”

  Zhong Weijian became more and more confused after hearing this.   Isn’t it normal for Kang Chi to give an open class at Su Province University?

  What’s the fuss?

  If I have to say something, it is that he is so idle that he would rather go to the university to give lectures to students than to arrange work for them…

  But there is actually nothing wrong with this.

  A class will not waste much time anyway, and it will not have much impact on the huge workload of planning large-scale scientific research directions.

  ”There is no problem, but his point of view… How should I put it? I can’t describe it.”

  Cheng Tao took out his mobile phone and handed it to Zhong Weijian after searching it casually on the Internet.

  ”You should take a look for yourself.”

  Zhong Weijian took the phone and sat on the sofa, then clicked to start playing.

  The content of the video is this open class.

  The reason why the open class is called an open class is that any student and teacher of Su Province University can come to listen. Su Province University even conducted a high-profile online live broadcast…     It is called to promote the enthusiasm of all people to learn.

But the brother colleges all smelled a strong sense of showing off…

Obviously, ordinary classrooms could not satisfy the enthusiastic students of Suzhou University, so the venue for the lecture became the school’s auditorium. Even though the venue was so large, it was basically full.

Since it was an open class for the public, Kang Chi did not intend to talk about too professional things. After saying hello, he talked about controlled nuclear fusion based on the opinions of students collected in advance by Suzhou University.

This is also the issue that everyone is more concerned about after Kang Chi became the chief engineer of controlled nuclear fusion.

As soon as Zhong Weijian finished reading the beginning, Cheng Tao reminded him: “What he said before was the importance of controlled nuclear fusion and the current mainstream research direction in the world. You can fast forward to 35 minutes…”

So Zhong Weijian dragged the progress bar directly and started reading from 35 minutes.

“…Take magnetic confinement devices such as tokamaks and stellarators as examples. Assuming that we have made a breakthrough in material technology, and have N120 magnetic pole materials and high-temperature carbon-based superconducting materials with a thermal conductivity of 6500W/m·k, and the performance of other major materials reaches the level in this table, and then upgrade and optimize the entire device, use deuterium-tritium as fuel, and assume that we have a perfect control system, it will work in a supercomputer.The simulation results will be——”

  Kang Chi released a calculated data:   [Tokamak: magnetic field strength 89.9T, Q value 2.6, first wall damage rate 0%…]

  [Stellarator: magnetic field strength 64.3T, Q value 3.2, first wall damage rate 0.0012%…]

  After seeing this string of data, Zhong Weijian’s pupils shrank for a moment, and then he looked up at Cheng Tao: “Do you think this premise… is possible?”

  Cheng Tao shook his head: “I’m not sure… If someone else said so, I think 100% is just a simple technical assumption. But if it’s Academician Kang… I personally think there is still a certain possibility, or he himself has great confidence that it can be realized. ”

 Cheng Tao’s words made Zhong Weijian’s hand holding the phone tremble slightly, and he didn’t hear anything Kang Chi said next.

  If the premise Kang Chi just said can be achieved, then there is no need to consider the confinement time at all, and the device can run as long as it wants.

  The confinement strength of 89.9T is enough to lock the nuclear fusion reaction firmly where it should be.

  The simulated damage rate of 0% of the first wall also proves this point with data.

  The magnetic confinement performance is even a bit excessive.

  However, considering that the magnetic field of the stellarator equipment is relatively complex, the magnetic field strength is reduced, resulting in a damage rate of 0.0012% for the first wall,

The data of Tokamak 89.9T may be the best parameter after optimization.

  But no matter what, if this premise can really be realized, the technology of controlled nuclear fusion can definitely take off and complete a technological leap forward!

  After Zhong Weijian took a break, he dragged the video back to 35 minutes with mixed feelings, watched it again carefully, and then continued to watch.

  ”Although the Q value of the stellarator can reach 3.2 at this time, it still cannot meet the commercialization of controlled nuclear fusion. It is like a gas-guzzling engine. It consumes a lot of fuel but can only output very little power. The cost-effectiveness of manufacturing and operating it is extremely low. We may need hundreds or even thousands of years to recover the cost.”

  A student below immediately raised his hand. After getting Kang Chi’s permission, he stood up and asked: “Why don’t you just assume the Q value is 5 and calculate the requirements of the device materials in reverse? ”

  ”Well… this is a good question. I have also conducted such simulations, but the calculations failed. It may be that my mathematical model is not good enough, or it may be that this parameter has far exceeded the definition of the model. In fact, the material parameters I am assuming now are already very difficult for us humans to achieve…”

  When he saw this, Zhong Weijian immediately understood.

  Kang Chi is not optimistic about the magnetic confinement route!

  And the tokamak and stellarator included in this route are the main research directions of controlled nuclear fusion at present…
