Chapter 537 Good News From Daya Bay

Although before that, Lu Zhou was also prepared for Hou Jinli to fail to complete this task, but he still lived up to his expectations.

Five sets of samples, each set of four pieces.

With the difficulty of laboratory preparation of ceramic-based graphene composites, 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 irradiation resistance in the high-energy region, Lu Zhou needs to diagnose the performance of these five groups of samples in the neutron irradiation environment of the relatively low-energy region.

If it's good, he'll consider testing it in a test pile.

After all, whether it is a tokamak or a stellarator, tens of billions of devices are not blown by strong winds. I don't know how long the days to come will be, so I'd better save some.

Unless it is to collect the necessary experimental data, or to try with confidence, it is far better to try it in the fission reactor first than to directly take it to the experimental reactor for testing.

Looking at Lu Zhou who was flipping through the report, Hou Jinli took a deep breath and continued.

"In the experiment, we simplified the original experimental steps and tried to find a more concise synthesis method!"

Hearing this unexpected news, Lu Zhou raised his eyebrows with interest: "Oh, really? Write a report and give it to me 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.

In terms of test results, the samples largely matched his calculations.

Next, we have to wait for the report from Daya Bay.

"If you have nothing else to do, you should go back early today. Seeing you like this, you can hardly stand still when you walk."

"it is good……"

Looking at Lu Zhou gratefully, Hou Jinli did not refuse.

After all, I am a third-year student, and my body is still not as good as it was when I first started my Ph.D.

His liver exploded for a week, and his body really couldn't hold it anymore...

...

As planned, Lu Zhou sent the five sets of samples to Daya Bay through a special logistics channel.

After waiting patiently for a while, the test results over there were quickly sent.

"The test results from Daya Bay have come out."

Putting a document on Lu Zhou's desk, Yang Xu said excitedly, "The result is perfect!"

Although Yang Xu's expression had completely spoiled the content of the test result, Lu Zhou immediately reached out to take the information and began to scan it impatiently.

The five groups of materials were collected in terms of DPA production rates in different energy regions in different irradiation scenarios such as pressurized water cooled reactor (PWR) and light water reactor (BWR).

As a control group, austenitic steel is usually used as a structural material in fusion devices.

As Yang Xu said, the experimental results are quite perfect.

Although there are considerable discrepancies between many numerical values ​​and the results simulated by his computational materials science method, the errors are all within an acceptable range.

After all, the Lindhard-Robinson model he referred to is not a particularly perfect phenomenological model. If the data is completely consistent, it is called abnormal.

Comparing five groups of samples horizontally, with the increase of neutron fluence rate, among them, the permeability to neutrons and the self-healing property to Frenkel defect pairs are the best in 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/cm, the DPA production rate is less than 10% of that of the control austenitic steel!

In radioactive detection, the dpa index is usually used to represent the number of dislocations per atom.

There is no doubt that they succeeded!

At least, in the low energy region...

Compared to Yang Xu's excitement, Lu Zhou's reaction was calm.

After reading the document from beginning to end, he thought for a moment before speaking.

"The irradiation temperature is only 680K, the fast neutron fluence is obviously not enough, and the energy carried by a single neutron has only reached the order of 1MeV. Don't rush to be happy. Our goal is the structural material of the fusion reactor, and this can only It’s a phased achievement.”

Although the results of this phased research are quite astonishing.

At least in the low-energy region, the performance of this ceramic-based graphene composite material has completely exploded Al, Mg, and Zr alloys that are commonly used as experimental reactor cladding materials.

And its anisotropy in heat transfer is needless to say.

Judging from these excellent properties alone, even if this material is not used in fusion reactors, it has a high application prospect in partial fission reactors.

Yang Xu smiled and said: "It's too harsh for you to say that. Even if it is a phased achievement, this achievement is not small. I think it's okay to be happy."

Lu Zhou smiled: "Maybe, but I still prefer to wait until everything is settled before tasting the champagne of victory."

Yang Xu: "So...does it still have to be tested in the fusion device?"

Lu Zhou nodded: "At present, this is the only way to go."

Only the fusion reactor itself can simulate the environment of the fusion reactor.

Yang Xu: "Leaving aside the matter of the fusion reactor, what name do you plan to give our material? Since the No. 4 sample has been confirmed as the best stage result, we can't still call it by number."

When he heard that he had to choose his own name, Lu Zhou suddenly had a difficult time and said with a headache.

"Don't leave it to me to choose the name. Refer to the opinions of Hou Jinli's research team. You can decide for yourself."

"How can that be done?" Yang Xu said with a smile, "According to the usual practice, the person in charge of the project decides to name the research results. If you really don't know how to do it, you can put the name on it."

Upon hearing this suggestion, Lu Zhou coughed lightly and said, "Forget the name, I'll think about it later."

I always feel that he still has a lot of research results in the future.

If they are all named by people's names, his two-character name may not be enough. I'm afraid that in the end even he himself will not be able to remember which is which.

After thinking about this serious question for a moment, Lu Zhou suddenly opened his eyes and said.

"...Just call it LPC-1."

Yang Xu: "..."

Seeing Yang Xu's speechless expression, Lu Zhou was slightly taken aback.

"What's wrong?"

Yang Xu coughed dryly, concealed his embarrassment and said, "It's nothing, it's a pretty good name. I just think... this naming rule is quite your style."

LPC is the abbreviation of porous carbon material. The first generation of products is followed by a number 1. Basically, this is the most confusing nomenclature, but it is also the least creative nomenclature.

It is too casual to name such an important research result.

Hearing Yang Xu's complaints, Lu Zhou probably guessed what he was thinking, so he smiled and said: "It doesn't matter what the material is called, what matters is its function."

Yang Xu: "Okay, as long as you are happy...By the way, if you plan to test it in the experimental pile, are you going to go to the southwest again?"

Lu Zhou shook his head: "The situation of HL-2A has reached its limit. Judging from the situation of the last experiment, I'm afraid it will be enough for them to repair until the end of the year. This time I will not force them."

Although I don't mind tossing Lao Zhou's equipment a few more times, no matter how much I toss, I still have to consider the basic law.

Injecting nuclear fuel into the experimental reactor is no joke. Although the fusion reaction will stop at any time, if the plasma of hundreds of millions of degrees leaks out, it will be a serious accident.

Having said that, Lu Zhou paused for a moment, and said in a joking tone.

"What's more, this is a moment to witness history, and maybe it will be included in textbooks in the future."

"It would be a pity to let other people's equipment witness."
