There was no waiting for long, and soon other people from the institute arrived.
Sitting in front of the conference table, Professor Li Changxia from Nanhua said with a solemn expression: "... The tritium remaining in the liquid lithium can be collected and solved. Just add a filling port on it and inject it into the reactor, like It is theoretically feasible to leave the work of separating helium ash to the divertor inside the reactor, or to add a separation device in front of the feed port. However, the key now is the thickness of the liquid lithium layer. We have done several sets of experiments. But the results were not very good.”
Just like those empirical formulas in fluid mechanics, it is impossible to fully explain them with existing theories, but this does not prevent people from using them on aircraft wings, engines, etc.
Referring to the set of mathematical models he left behind and the set of control plans edited by professors from the Software School of Jinling University, he calculated and simulated the movement trajectories of the elementary elements in the plasma in countless experiments, and finally carried out the phenomenological model. Correction, set additional parameters to make it as close to perfect as possible.
If you think about it this way, does this thing count as his and Xiao Ai's child
He always felt that if he thought so, he would be unable to look directly at the guy on the computer.
But there was nothing we could do about it. After all, no one expected it to be so troublesome at first. He originally thought that since the plan was so detailed and engineers from the Nuclear Industry Group were cooperating with them, the problem wouldn't be too big, so he focused on developing LPC-1 materials.
Lu Zhou: "Have you brought the experimental data?"
Quickly browsing the code on the screen, a look of surprise appeared on Lu Zhou's face.
The thickness of the liquid lithium layer is a very critical issue, whether it is too thick or too thin is not good.
However, this kind of AI is undoubtedly much lower level than Xiao Ai.
The recovered tritium exists in the form of gas and is recovered at the top of the device and reinjected into the reaction chamber to participate in the reaction.
Sheng Xianfu nodded and immediately handed over a document.
In short, this algorithm is probably a product of machine learning.
Ideally, liquid lithium would be used to recover neutrons before they are reflected twice at the beryllium metal interface. However, it is not easy to do this.
In the field of application, when the phenomenological model is developed to its extreme, it is no different from a simple and pure theory.
"Okay, I'll go right away."
Seeing Lu Zhou appearing in the research institute, Sheng Xianfu, who had not had a good night's sleep this month, smiled haggardly.
At least there isn't much difference in use.
If it is too thick, a large amount of tritium will be retained inside the liquid lithium, reducing the recovery efficiency, greatly increasing the engineering difficulty, and may also affect the safety of the entire reactor.
Now that the first wall material has been solved, a series of devices from core collectors to heating components are being steadily advanced under the work of other research institutes. However, they who are responsible for the core part of the project have to No substantial progress has been made so far.
Nodding, Sheng Xianfu turned and walked quickly towards the office.
"I'll take this thing back and think about it."
This technical route was proposed by him, but he himself has been busy with other projects and has not paid attention to it.
Collecting this data and correcting the original control plan through continuous calculation simulations may take several years or even ten years if these tasks are completed by humans.
Although the work of the STAR Research Institute did not stop during the time he was in Haizhou, the progress in the past month was no different from the previous month. At least, nothing could be called a phased development. The results come.
In this sense, the algorithm of the plasma control scheme separated from Xiaoai's main program seems to be a kind of AI developed from machine learning technology.
"The meeting will end here. You can go back first. Starting today, all departments will have two days off. We will report back the day after tomorrow."
Lu Zhou took the document and read it carefully.
After finally reading the information in his hand, Lu Zhou closed the document.
Even if no one urges them, they still bear a lot of pressure.
Now that Lu Zhou came back from Haizhou, everyone in the place breathed a sigh of relief.
The moment it appeared, Lu Zhou quickly threw it behind his head and turned off the computer.
Of course, it won't work if it's too thin, as it will directly affect the proliferation rate of tritium. After all, the half-life of a free neutron is only about 10.6 minutes, which means that while considering the transmutation of neutrons with other elements, they also have to consider the decay of the neutron itself.
The next morning, Lu Zhou got up early and called Wang Peng, asking him to bring a basket of soup dumplings when he came over. After finishing his breakfast while drinking soy milk and dipping it with shredded ginger and old vinegar, he set off for the STAR Research Institute.
"Let's have a meeting with the people in the office," Lu Zhou nodded and gave the order, "I'll understand the situation first."
"It's not hard work," Sheng Xianfu said with a sigh as he scratched his thinning hair, "It's just that we can't solve a few key problems, and thinking about it makes people's heads ache."
After announcing the end of the meeting and the holiday arrangements, Lu Zhou gently patted the information on the table in the face of the unexpected glances.
Lu Zhou: "...Thank you for your hard work."
The matter of the plasma control scheme has come to an end. Once the supercomputer of the demonstration reactor project is completed, the backup program will be migrated there.
"You're finally back. I'm thinking that if you don't come back, I'll go find you."
This kind of systematic scientific research project is like a bucket. No matter which plank is short, it will not be able to draw water.
After hearing this, Lu Zhou looked a little embarrassed.
After giving instructions for the meeting, Lu Zhou first returned to his office and took out the plan for the liquid lithium neutron recovery system and reviewed it again. Then he got up and headed to the institute's conference room No. 1.
According to several department heads, the current research is basically based on the idea he formulated before going to Haizhou.
However, this bad thought only passed for a moment.
"I see… "
Unexpectedly, he underestimated the difficulty of this subject.
"The research idea is right, these data are very important, but some methods are missing, so the expected results were not achieved. You have done a good job during this period, and you haven't had much rest in the past month. .”
But for Xiao Ai, who lives in the supercomputer and can make corrections to the control plan immediately, it may be enough to run the stellarator a few times.
Time passed by, and the conference room was so quiet that the only sound that could be heard was the ticking of the clock on the wall.
Since joining the research institute here, he feels that his hair is getting thinner and thinner.
Just when everyone thought the big boss would come up with an idea, his actions surprised everyone.
With his coding ability, it may be difficult to fully understand this algorithm, but if he only understands the execution logic of the entire plasma control scheme from a few key command lines, it will be no problem for him.
Lu Zhou said nothing, and the researchers sitting at the conference table also waited patiently.
That is, the LPC-1 material of the first wall is used to transmit and decelerate neutrons. The subsequent liquid lithium circulation device absorbs neutrons and releases tritium. The beryllium reflective layer covering the liquid lithium layer absorbs the incompletely reacted neutrons. The sub bounces back.
"After three days, I will give you a result!"
…
"it's here."
In addition to the plasma control plan, Lu Zhou's other main purpose of returning this time is to complete the final design of the liquid lithium neutron recovery system.
After convening researchers and engineers from the STAR Research Institute, Lu Zhou held a brief meeting and learned about the situation from various departments.
