Even though Lu Zhou was prepared that Hou Jinli wouldn't be able to complete this task, Hou Jinli still lived up to his expectations.
Five sets of samples, four pieces each.
With the difficulty of preparing ceramic-based graphene composites in the laboratory, it wasn't easy to complete these tasks in a week.
In short, with these samples, Daya Bay should be able to make it in time.
Before testing the neutron radiation resistance in the high-energy region, Lu Zhou first needed to diagnose the performance of the five sets of samples in the relatively low-energy neutron radiation environment.
If the results were good, then he would consider testing them in the experimental reactor.
After all, whether it was the tokamak or the stellarator, they weren't equipment worth tens of billions of yuan. Lu Zhou didn't know how long he would have to live in the future, so he had to use it sparingly.
Unless it was to collect the necessary experimental data, or if it was a confident attempt, it would be better to try it in the fission reactor than to directly test it in the experimental reactor.
Hou Jinli looked at Lu Zhou, who was flipping through the reports. He took a deep breath and spoke.
"In the experiment, we simplified the original experimental steps and tried to find a more concise synthesis method!"
When Lu Zhou heard this unexpected news, he raised his eyebrows and said, "Oh, really? Write a report in two days and give it to me. "
Hou Jinli immediately nodded and said, "Okay!"
After Lu Zhou finished reading the XRD test reports in his hand, he put down the information for the time being.
As far as the test results were concerned, these samples were basically in line with his calculations.
Next, he had to wait for the report from Daya Bay.
"If there's nothing else, you should go home early today. Look at you, you can't even walk properly."
"Okay …"
Hou Jinli looked at Lu Zhou gratefully and didn't decline.
After all, he was in his thirties, and his body wasn't as strong as when he was a PhD student.
After working hard for a week, his body really couldn't take it anymore …
…
Just like the plan, Lu Zhou used a special logistics channel to send the five sets of samples to Daya Bay.
After patiently waiting for a while, the test results were quickly sent over.
"The test results from Daya Bay are out."
Yang Xu placed a document on Lu Zhou's desk and said excitedly, "The results are perfect!"
Although Yang Xu's expression had already revealed the contents of the test results, Lu Zhou immediately reached for the information and impatiently scanned through it.
The five groups of materials were collected at different DPA production rates in different radiation scenarios, such as the pressurized water-cooled reactor (PWR) and the light water reactor (BWR).
The control group was austenitic steel, which was commonly used as a structural material in fusion devices.
Just as Yang Xu had said, the results of the experiment were perfect.
Although many of the values were quite different from the results of his computational materials science simulation, the error was within an acceptable range.
After all, the Lindhard-Robinson model was not a perfect phenomenological model. If the data matched, it would be abnormal.
The five sets of samples were compared horizontally. As the neutron fluence rate increased, the fourth set of samples was the best in terms of neutron penetration and self-healing of the Frenkel defect pair.
Especially in the PWR environment, where the radiation temperature was 680K and the fast neutron fluence rate reached 4, the DPA production rate was less than 10% of the control austenitic steel!
In radioactivity detection, the DPA index was often used to represent the number of dislocations of each atom.
Without a doubt, they succeeded!
At least, this was the case in the low-energy region …
Compared to Yang Xu's excitement, Lu Zhou's reaction was relatively calm.
After he read the information from beginning to end, he thought for a bit and spoke.
"The radiation temperature is only 680K, and the fast neutron fluence is obviously not enough. The energy carried by a single neutron is only in the order of 1MeV. Don't be too happy yet, our goal is the structural material of the fusion reactor, and this is only an in-progress result."
However, this in-progress research result was quite amazing.
At least in the low-energy region, the performance of this ceramic-based graphene composite completely surpassed the common experimental reactor materials, such as Al, Mg, and Zr alloys.
Also, its anisotropy in heat transfer was self-explanatory.
Looking at these excellent properties, even if this material wasn't used in fusion reactors, it would still have high application prospects in fission reactors.
Yang Xu smiled and said, "You're being too harsh. Even though this is an in-progress result, it's not a small result. I think it's okay to be happy."
Lu Zhou smiled and said, "Maybe, but I prefer to wait until the dust settles before I taste the champagne of victory."
Yang Xu: "So … Do we still have to test it in the fusion reactor?"
Lu Zhou nodded and said, "For now, that's the only way."
The only thing that could simulate the fusion reactor environment was the fusion reactor itself.
Yang Xu: "Let's not talk about the fusion reactor for now. What do you plan on naming this material? Since we've confirmed the No. 4 sample as the best in-progress result, we can't just call it by a number, right? "
When Lu Zhou heard that he had to name it, he felt like he was having a headache.
"Don't leave the naming to me. Refer to Hou Jinli's research team's opinion, and you guys can decide."
"How can I do that?" Yang Xu smiled and said, "Normally, naming research results is decided by the person in charge of the project. If you really don't know, you can just use a person's name. "
When Lu Zhou heard this suggestion, he coughed and said, "Forget about the name, I'll think about it."
Lu Zhou felt like he had a lot of research results in the future.
If he used a person's name, his two-character name wouldn't be enough. In the end, he wouldn't even remember which was which.
Lu Zhou thought about this serious problem for a second. His eyes suddenly lit up.
"… Let's call it LPC-1."
Yang Xu: "…"
When Lu Zhou saw how speechless Yang Xu was, he paused for a second.
"What's wrong?"
Yang Xu coughed and said, "Nothing, it's a good name. I just think … this naming method is quite your style. "
LPC was the abbreviation for porous carbon material. The first generation of products had a number 1 behind it. This was the least confusing naming method, but it was also the most uncreative naming method.
It was too careless to name such an important research result.
When Lu Zhou heard Yang Xu's words, he guessed what he was thinking. He smiled and said, "It doesn't matter what the material is called, what's important is its function."
Yang Xu: "Okay then, as long as you're happy … Oh yeah, if you plan on testing it in the experimental reactor, do you plan on going to Southwest again?"
Lu Zhou shook his head and said, "HL-2A has reached its limit. Looking at the results of the last experiment, I'm afraid it'll take them until the end of the year. I won't force them this time."
Even though Lu Zhou didn't mind messing with Old Zhou's equipment a few more times, he still had to consider the basics.
Injecting nuclear fuel into the experimental reactor wasn't a joke. Even though the fusion reaction could stop at any time, if hundreds of millions of degrees of plasma leaked out, it would be a serious accident.
Lu Zhou paused for a second and spoke in a joking tone.
"Not to mention, this is a historical moment. It might even become a textbook in the future."
