"I see …"
Lu Zhou quickly browsed through the code on the screen and had a look of realization on his face.
With his coding skills, it would be difficult for him to completely understand this set of algorithms. However, if he only had to understand the execution logic of the plasma control scheme from a few key command lines, then it shouldn't be a problem for him.
Basically, this set of algorithms was a product of machine learning.
Using the mathematical model he left behind and the control scheme edited by the Jin Ling University software department professors, Lu Zhou calculated and simulated the motion trajectory of the elementary elements in the plasma through countless experiments. Finally, he modified the phenomenological model and set additional parameters to make it as close to perfection as possible.
In the field of application, when the phenomenological model was developed to the extreme, it was no different from a simple and pure theory.
At least there wasn't much of a difference when it was used.
Just like the empirical formulas in fluid mechanics, it was impossible to completely explain it using existing theories. However, this didn't prevent people from using it on airplane wings, engines, etc.
Collecting these data and modifying the original control scheme through continuous calculations and simulations would take several years or even ten years to complete if this work was done by humans.
However, for Xiao Ai, who was residing in the supercomputer, it could modify the control scheme immediately. It might be enough for the stellarator to run a few times.
Therefore, the plasma control scheme algorithm that was separated from Xiao Ai's main program could also be considered an AI developed from machine learning technology.
However, this type of AI was undoubtedly much lower level than Xiao Ai.
Thinking about it this way, does this thing count as my and Xiao Ai's child?
However, this thought only flashed in his mind for a second.
The second it appeared, Lu Zhou quickly threw it to the back of his head and turned off his computer.
He felt like he couldn't look at the guy in the computer anymore.
…
The plasma control scheme issue had come to an end. Once the demonstration reactor supercomputer was built, the backup program would be migrated over.
The next morning, Lu Zhou woke up early and called Wang Peng. He asked Wang Peng to bring him some soup dumplings. He drank soy milk and ate his breakfast with ginger and vinegar before heading to the STAR research institute.
Other than the plasma control scheme, Lu Zhou's other main purpose this time was to complete the final design of the liquid lithium neutron recovery system.
Even though the STAR research institute's work didn't stop while he was in Haizhou, the progress over the past month was no different from the previous month. At the very least, they didn't produce any in-progress results.
This kind of systematic scientific research project was like a bucket. If any of the wooden boards were short, they would not be able to draw water.
Now that the first wall material was solved, a series of devices, such as the nuclear core catcher and heating components, were progressing steadily with the work of other research institutes. However, they were responsible for the most important part of the project, and they hadn't made any substantial progress so far.
Even if no one urged them, they were still under a lot of pressure.
Now that Lu Zhou had returned from Haizhou, everyone in the institute breathed a sigh of relief.
When Sheng Xianfu saw Lu Zhou appear at the research institute, he smiled. He hadn't slept much this month.
"You're finally back. I was thinking that if you didn't come back, I would've gone to find you."
Lu Zhou: "… Thank you for your hard work."
"Not at all." Sheng Xianfu scratched his sparse hair and sighed. He said, "It's just that there are a few key problems that can't be solved. It's giving me a headache."
Ever since he joined the research institute, he felt like his hair was getting thinner and thinner.
When Lu Zhou heard this, he looked a little embarrassed.
He was the one who proposed this technical route, but he had been busy with other research projects, so he didn't have time to think about this.
However, there was nothing he could do about it. After all, no one expected it to be this troublesome. He originally thought that since the proposal was so detailed, and the engineers from the China National Nuclear Corporation were cooperating with them, it shouldn't be a big problem. Therefore, he focused on the LPC-1 material.
However, he didn't expect that he underestimated the difficulty of this research project.
"Gather everyone in the institute for a meeting." Lu Zhou nodded and said, "I'll understand the situation first."
"Okay, I'll go right now."
Sheng Xianfu nodded, turned around, and walked quickly toward the office.
After giving instructions for the meeting, Lu Zhou first returned to his office. He took out the liquid lithium neutron recovery system proposal and reviewed it again. He then got up and went to conference room number one at the research institute.
He didn't have to wait for long before the other people in the institute arrived.
Lu Zhou gathered the researchers and engineers at the STAR research institute and held a brief meeting. He learned about the situation from the various departments.
According to the heads of several departments, the current research basically revolved around the idea that he formulated before he went to Haizhou.
Which was to use the LPC-1 material on the first wall to pass through and decelerate the neutrons. The liquid lithium recycling device then absorbed the neutrons and released thorium. The beryllium reflector outside the liquid lithium layer bounced back the neutrons that were not completely reacted.
The recovered thorium was in the form of a gas, which was recovered at the top of the device and re-injected into the reaction chamber to participate in the reaction.
Professor Li Changxia, who came from Yuhua, was sitting at the conference table. He said with a solemn expression, "… The thorium trapped in the liquid lithium is easy to collect. We just need to add a filler and inject it into the reactor. The work of separating the helium ash can be done by the divertor inside the reactor, or we can add a separation device in front of the inlet. However, the key is the thickness of the liquid lithium layer. We've done a few experiments, but the results aren't very good. "
The thickness of the liquid lithium layer was a very important issue. It didn't matter if it was too thick or too thin.
If it was too thick, a large amount of thorium would be trapped inside the liquid lithium, which would reduce the recovery efficiency and greatly increase the engineering difficulty. It might also affect the safety of the entire reactor.
If it was too thin, it wouldn't work either. It would directly affect the proliferation rate of thorium. After all, the half-life of a free neutron was only around 10.6 minutes. This meant that while they considered the evolution of neutrons with other elements, they also had to consider the decay of the neutron itself.
The ideal situation was to use liquid lithium to recover the neutrons before they had a second reflection at the beryllium metal interface. However, it wasn't easy to do this.
Lu Zhou: "Did you bring the experimental data?"
"Here it is."
Sheng Xianfu nodded and immediately handed over a document.
Lu Zhou took the document and began to read it carefully.
Time quickly passed by. The conference room was so quiet that only the ticking of the clock could be heard.
Lu Zhou didn't say anything, and the researchers sitting at the conference table waited patiently.
Lu Zhou finally finished reading the information in his hand and closed the document.
Just when everyone thought that this big shot would come up with an idea, his actions were beyond everyone's expectations.
"The research idea is correct, and the data is very important. It's just that some methods are missing, so we didn't achieve the expected results. You guys have done a good job, you guys haven't had a good rest in the past month, right?
"This is the end of the meeting. You guys can go back first. Starting from today, all departments have two days off. Report back the day after tomorrow."
Lu Zhou announced the end of the meeting and the holiday arrangements. He looked at the surprised gazes and gently patted the document on the table.
"I'll take this back and think about it."
