Chapter 536: Daya Bay News

Although before this, Lu Zhou was also ready for Hou Jinli's failure to complete this task, but sure enough he still did not live up to his expectations.
Five groups of samples, four in each group.
The laboratory preparation of ceramic-based graphene composites is difficult, and it is not easy to complete these tasks within a week.
In short, with these samples, Daya Bay should be able to catch up.
Before testing the neutron radiation resistance in the high energy region, Lu Zhou needs to diagnose the performance of the five groups of samples in a relatively low energy neutron radiation environment.
If the situation is good, he will consider testing it in the experimental reactor.
After all, no matter whether it is a Tokamak or a stellar device, tens of billions of devices are not brought by the gale. I don't know how long it will be in the future.
Unless it is necessary to collect the necessary experimental data, or a sure attempt, it is better to try it in the fission reactor first than to directly test it in the experimental reactor.
Looking at Lu Zhou reading the report, Hou Jinli took a deep breath and continued.
"In the experiment, we simplified the original experimental steps and tried to figure out a more concise synthesis method!"
Upon hearing the unexpected news, Lu Zhourao raised his eyebrows with interest: "Oh, did you? Give me a report in two days."
Hou Jinli immediately nodded and said, "Okay!"
After reading the several XRD test reports in his hand, Lu Zhou put down these materials for the time being.
As far as the test results are concerned, these samples basically agree with his calculations.
Next, we have to wait for the report from Daya Bay.
"If there is nothing else, you should go back early today. Seeing you like this, you will be standing still."
"it is good"
A grateful look at Lu Zhou, Hou Jinli did not quit.
After all, it's also Ben San, and his body is still not as good as when he just read Bo.
He exploded for a week, and his body really couldn't hold it up.
As planned, Lu Zhou sent these five groups of samples to Daya Bay through special logistics channels.
After waiting patiently for a while, the test results over there were sent quickly.
"The test results from Daya Bay came out."
Putting a document on Lu Zhou's desk, Yang Xu said excitedly, "The result is perfect!"
Although Yang Xu's expression had thoroughly spoiled the content of the test result, Lu Zhou immediately reached out and retrieved the information, and couldn't wait to read it.
Five groups of materials were collected in different irradiation mockups such as pressurized water-cooled reactors (PWR) and light water reactors (BWR), and the DPA generation rates in different energy regions were collected.
As the control group, austenitic steel, which is usually used as a structural material in fusion devices.
As Yang Xu said, the experimental results are perfect.
Although many numerical values ​​and the results he simulated through computational materials science methods are not inconsistent, the errors are within an acceptable range.
After all, the Lindhard-Robinson model he was referring to was not a particularly perfect phenomenological model. If the data exactly match, then it is called abnormal.
The five groups of samples were compared horizontally. As the neutron fluence rate was enlarged, the permeability to neutrons and the self-healing ability to Frenkel defect pairs were optimized with the fourth group of samples.
Especially in the PWR environment, when the irradiation temperature is 680K and the fast neutron fluence reaches 4.2 × 1020 / cm2, the DPA production rate is less than 10% of the austenitic steel in the control group!
In radioactive detection, the dpa index is usually used to indicate the number of off-positions of each atom.
No doubt they succeeded!
At least, this is true in low energy
Compared to Yang Xu's excitement, Lu Zhou's response was rather calm.
After reviewing the material from beginning to end, he thought for a moment and then said.
"The irradiation temperature is only 680K, and the fast neutron fluence is obviously not enough. The energy carried by a single neutron has only reached the order of magnitude. Don't hurry, our goal is the structural material of the fusion reactor, and this can only be regarded as Phased results. "
Although this phase of research results, it is quite amazing.
At least in the low-energy region, the performance of this ceramic-based graphene composite has already exploded Al, Mg, Zr alloys commonly used as experimental reactor cladding materials.
Moreover, its anisotropy in thermal energy transmission is unnecessary.
Judging by these excellent properties, even if this kind of material is not used in the fusion reactor, it has great prospects for being placed on a partial fission reactor.
Yang Xu smiled and said, "It's too harsh for you to say that, even if it's a staged result, this result is not too small. I think there is nothing wrong with happiness."
Lu Zhou smiled, "Maybe, but I still prefer to wait until all the dust is settled before tasting the champagne of victory."
Yang Xu: "So I still have to test it in a fusion device?"
Lu Zhou nodded: "At present, this can only be the case."
Only the fusion reactor itself can simulate the fusion reactor environment.
Yang Xu: "Let's not talk about the fusion reactor first. What name do you plan to give us for this material? Since the No. 4 sample has been determined as the optimal stage result, you can't always call it by the number."
When he heard that he wanted to pick his own name, Lu Zhou suddenly had a hard time, and said with a headache.
"Don't leave it to me for the name. Refer to Hou Jinli's research team for advice. You can decide for yourself."
"How do you do that?" Yang Xu said with a smile. "According to the usual practice, naming research results is the responsibility of the project leader. If you really don't, you can put your name on it."
Upon hearing this suggestion, Lu Zhou suddenly coughed and said, "The name is still fine, I will consider it again."
I always feel that he will still have a lot of research results in the future.
If they are all named after people, UU Kanshu www.uukanshu.com his two-character name is probably not enough, I'm afraid that in the end, even he himself can't remember which one is that.
After thinking about this serious question for a moment, Lu Zhou suddenly opened his eyes and said.
"Just call LPC-1."
Yang Xu: ""
Seeing Yang Xu's speechless expression, Lu Zhou froze slightly.
"what happened?"
Yang Xugan coughed, concealing his embarrassment and said, "It's nothing, a good name is because I think this naming rule supports your style."
LPC is an abbreviation of porous carbon material. The first generation product is added with a number 1 at the back. Basically, this is the least complicated nomenclature, but it is also the least creative nomenclature.
It is too casual to name such important research results.
After hearing Yang Xu's utterance, Lu Zhou probably guessed what he was thinking, so he smiled and said, "What the material is called is not important, what is important is its function."
Yang Xu: "Okay, you're just fine. If you plan to test in the experimental reactor, are you going to go to the southwest side again?"
Lu Zhou shook: "The situation of HL-2A has reached its limit. Judging from the conditions of the last experiment, I am afraid that they will be able to repair it until the end of the year. This time I will not force them.
Although you don't mind to toss Lao Zhou's equipment a few more times, you must consider the Basic Law no matter how toss.
Injecting nuclear fuel into the experimental reactor is not a joke. Although the fusion reaction will stop at any time, if hundreds of millions of degrees of plasma leak out, it will be a serious accident.
Having said that, Lu Zhou paused for a moment, and said jokingly.
"What's more, this is a moment to witness history, and I may not have access to textbooks in the future."
"It would be a shame to let someone else's equipment witness."
