Chapter 533: Revisit the old industry

After not staying here for a long time in the southwest, after getting the required data, Lu Zhou took the return plane the next day and returned to Jinling with a few researchers brought from the Star Institute.
With the departure of Lu Zhou and his party, almost the entire Southwestern Institute of Nuclear Physics has lost their breath.
These guys are almost like a bandit, they are all feathers wherever they go. They finished the experiment, and smacked their farts with the data. The shares left, but the mess left behind had to be cleaned up by themselves.
Many people are debating whether this guy is here for public grudges, and it is hard to say whether the experiment itself is meaningful or not. After all, this guy took confidentiality as a cover, not only took away the samples, but he didn't even leave a backup of the data for them.
But no matter what, after this incident, Zhou Chengfu's prestige in the courtyard can be regarded as sweeping the floor with him ...
Standing in Zhou Chengfu's office, Jia Liangcai looked relieved.
"... this plague is gone."
Sitting expressionlessly on an office chair, Zhou Chengfu said slowly.
"How's the situation with hl-2a?"
After hearing this question, Jia Liangcai's face was relieved and gradually became a bitter expression.
"The test report of the radiation damage has not been made yet ... but according to the engineers at the institute, the situation is not optimistic."
Zhou Chengfu: "How do you say?"
"There are swellings of varying degrees inside the structural material. As for the first wall ... it's basically brittle!" Jia Liangcai said with a heavy face.
Originally, experimental reactors were not used for fusion ignition. The plasma experiments now performed are only to simulate the operating environment of plasma under high temperature and high density.
Therefore, the resistance of the materials on hl-2a to neutron irradiation is basically the level of the fission reactor, and even less.
Therefore, this tragedy of hl-2a is almost inevitable.
Although he had prepared in his heart, Zhou Chengfu couldn't help twitching his lips after hearing this sentence.
Taking a deep breath, holding back the pain in his heart, he began.
"Can it be repaired?"
Jia Liangcai nodded reluctantly: "I asked the engineers in the institute if they can fix it, but in the short term ... I'm afraid it won't work."
There are too many things to change after all.
Zhou Chengfu was silent for a while and began to speak.
"After the radiation damage test is done, remember to keep all this information."
Jia Liangcai froze slightly, and then there was a faint flash on his face: "You are planning ..."
With an angry flame flashing in his eyes, Zhou Chengfu gritted his teeth and said, "This is not the case."
If only he did it.
If you can't do it ...
He vowed that he would definitely go to Beijing with these "evidence" and sue the case in person.
...
To others, this data may not be of much use, but to Lu Zhou, it is invaluable.
Mathematics is a powerful scientific tool and also his most powerful weapon.
Although the conclusions obtained through calculations cannot directly analyze the results he needs, as a reference, they can help him take a lot of detours.
"It's been a long time since I was so excited."
Sitting in his own study, staring at the data and pictures in the computer, Lu Zhou's pupils flashed with excitement.
Sure enough, rather than directing others to conduct experiments, he is still on the front line of scientific research positions, and he feels more happy to solve these problems in person.
After stretching himself, he picked up the pen and wrote on a brand-new blank paper.
[Irradiation Damage Energy: tdam = td (1 + kg (e)) ^-1]
[K = ξ0.0793 (a1 + a2) ^ 3/2 · z1 · z2 / (z1 ^ 2/3 + z2 ^ 2/3) a1 ^ 2/3, ξ≈z1 ^ 1/6]
[E = ……]
It is worth mentioning that due to the expensive cost of neutron irradiation experiments, in the study of radiation damage to materials by neutron beams, the nuclear physics community developed a set of Calculation method of important parameters such as speed, and can be simulated based on programs such as njoy.
Because it is an phenomenological model built by empirical formulas, there are many related calculation methods. As for Lu Zhou's choice, it is a relatively reliable lindhard-robinson model.
According to the theory of the model, after selecting an expected dpa interval and the maximum value of he production rate, he changed some constants in the ceramic-based graphene composite material into variables, and then integrated into his own research. The theory of computational materials science has numerically simulated materials that may fit the dpa interval and the rate of he production.
Although this seems easy to say.
But in fact, this process is far more difficult than simulating the dpa and he generation rate of a certain material under specific neutron irradiation conditions based on the lindhard-robinson model.
Moreover, the results obtained by the simulation are not necessarily reliable.
This situation is common in computational materials. Although some mathematically reasonable results can be obtained, it is impossible to consider them from a practical perspective.
Especially in the presence of negative parameters ...
Time passed day by day, and gradually entered the state of the land boat. These days, they have basically locked themselves up at home.
During this period, Principal Xu called him and asked him if he had time to speak at the opening ceremony, but Lu Zhou couldn't find any time, so he pushed it out.
With regard to Lu Zhou's reply, President Xu naturally expressed understanding.
In any case, such a major national scientific research project is still ranked first.
However, he also persuaded Lu Zhou on the phone at the same time, so that he should not be too desperate. Even if he was too busy, he would have to take time to walk around. After all, the body is the capital of life. If you break down your body, you will lose more.
No matter how President Xu advised, Lu Zhou certainly came at his own pace.
Before the research results came out, it was impossible for him to go out.
Just half a month after the retreat, in mid-September, Lu Zhou finally completed the last step.
He drew a long breath and leaned on the chair, looking at the calculations on the screen, a smile gradually evoked in the corner of his mouth.
The framework of the entire model has been completed by him.
The rest is the flesh that fills it.
This is the calculation part.
"Ai, give you a task."
Just as his voice fell, a small bubble popped up in the lower right corner of the desktop.
【Yes! the host! (??????) ゞ]
Although the amount of calculation is quite huge, but with supercomputing computing power as the support, it is not difficult for Xiao Ai to complete this kind of uncreative work.
After explaining the specific task verbally, Lu Zhou stood up from his seat.
Moving his sour arms and shoulders, bypassing the draft paper on the floor, he went to the kitchen and made himself a cup of instant coffee.
While waiting for the coffee to open, he took out his mobile phone, checked the text messages, missed calls, and email address, and made simple responses to those who could not reach him in the past few days.
After doing these things, Lu Zhou returned to the study with his coffee.
When he sat down at the desk again, the calculated results were already in front of him.
After looking at the simulation results from beginning to end, Lu Zhou's mouth evoked a smile.
The results are quite perfect.
Excluding a few apparently unachievable results, he got at least five sets of feasible data.
Each of these data sets corresponds to a theoretically feasible option.
"Next, it's time to verify these possibilities in the lab!"
