Chapter 402 Good News From Daya Bay!

Through a special logistics unit, Xu Chuan sent the samples to Daya Bay.

The rest is to wait.

Although the slow neutron irradiation experiment is not particularly time-consuming, it always takes some time to prepare for the work and process the relevant data.

And this period of time seems particularly long for the researchers in the computational materials research laboratory who are full of expectations.

Especially Zhao Guanggui, after a night's rest, he ran to Xu Chuan's office the next day to consult about the situation.

Although Xu Chuan can understand this expectation and the mood of being eager to know the results, it must be said that the frequency of Professor Zhao coming to disturb him is almost interfering with his normal work.

After all, he is the general manager of the Qixia controlled nuclear fusion project. In addition to the first wall material, there are other problems waiting for him to solve or distribute.

Fortunately, this wait is not long.

With the highest priority marked, in early March of the solar calendar, the Daya Bay Neutron Radiation Laboratory Center conducted the first batch of slow neutron irradiation experiments on zirconium oxide carbon composite materials.

After waiting for another three days, the relevant analysis data and samples after slow neutron irradiation were transported back to the Qixia controlled nuclear fusion project through logistics.

"The test results from Daya Bay are out."

After the result report of the slow neutron irradiation experiment was sent to Xu Chuan's office, Xu Chuan called Zhao Guanggui and told him the long-awaited news.

In less than five minutes, Zhao Guanggui rushed over quickly.

"Academician Xu, what are the test results?!" Zhao Guanggui asked excitedly and urgently as soon as he entered the door.

Xu Chuan smiled, pushed the test report on the desk forward, and said with a smile: "You can see it yourself."

Hearing this, Zhao Guanggui couldn't wait to reach out and take the test report from the desk and read it.

He knew very well about the materials sent to Daya Bay for testing.

Because of the urgency of time, as many as twelve groups of materials were sent there.

These twelve groups of identical materials were simultaneously subjected to different slow neutron irradiation tests in different irradiation scenes to achieve the purpose of obtaining data at the same time and saving time.

Of course, along with these materials, there are other control materials entering the test site, such as austenitic steel, tungsten-molybdenum alloy, ceramics, etc.

These control materials are commonly used as structural materials or first wall materials in fusion devices, which can better reflect the neutron irradiation resistance of the test materials.

[A set of irradiation conditions: PWR pressurized water-cooled reactor, irradiation temperature of 702K, fast neutron injection amount of 5.1×10/cm]

[A set of irradiated materials: experimental group (zirconia carbon composite material) control group (austenitic steel + tungsten gold)],

[A set of DPA generation rate: experimental group (0.17%), control group (2.4%)]

[A set of neutron penetration: experimental group (99.98%), control group (67.44%)]

[A set of self-healing of Frenkel defect pairs:]

One by one, the experimental data quickly passed through his eyes, accompanied by the almost uncontrollable joy and excitement.

In the first wall material, whether it is the Dpa generation rate, neutron penetration, or the self-repair of Frenkel defect pairs, they are all very important indicators.

Especially for the first wall structure designed for the Dawn Fusion Experimental Device, it is even more important.

First of all, the DPA generation rate. In radioactive detection, the dpa index is usually used to indicate the number of times each atom is dislocated, which does not need too much explanation.

And the neutron penetration represents the index of the stable penetration of the high-energy neutron beam through the material, which is the key to their ability to bombard the lithium target with a high-energy neutron beam to obtain tritium and complete tritium self-sustaining.

As for the self-repair of Frenkel defect pairs, it represents the parameter of the degree of self-repair of the damaged lattice after being bombarded by high-energy neutrons.

From the test data transmitted back from Daya Bay.

There is no doubt!

They succeeded!

They successfully manufactured a material suitable for the first wall of controlled nuclear fusion!

Although this is only a slow neutron irradiation test, it is a historical record.

Because, in the past, no matter which country, or which research institute or laboratory, has never produced neutron-resistant materials that can match the data in the test report in hand.

Clenching his fist tightly, Zhao Guanggui looked extremely excited, and looked at Xu Chuan with excitement.

"Academician Xu, we..." He opened his mouth, and he was so excited that he wanted to say something but stopped.

Xu Chuan smiled. Compared with Zhao Guanggui's excitement, he was much calmer.

"From the experimental test data of slow neutron irradiation in Daya Bay, we did succeed."

"However." After a pause, he continued: "Compared with the real deuterium-tritium fusion in the chamber of a controlled nuclear fusion reactor, the neutron irradiation experiment in Daya Bay is not enough in terms of energy level or temperature."

"The highest neutron energy level in Daya Bay is only 1.2Mev, while the energy level of each neutron beam released in the chamber of a controlled nuclear fusion reactor is as high as 14.1 MeV. And in terms of temperature, the highest test temperature is only 720K, which is nearly 2,000 degrees lower than the real experiment."

"So, don't be so happy in a hurry. Our goal is to be the first wall structure material suitable for the Dawn fusion reactor, and this can only be regarded as a phased achievement."

"After it passes the complete test of the Dawn fusion device, it will be completely in time to celebrate."

Of course, although this material is indeed a phased research result at present, its value is also quite amazing.

Apart from other things, in the field of nuclear fission, with the excellent performance of this material, it can largely replace the cladding structure material.

After all, although the production of carbon nanotubes is difficult, it is not a very expensive thing.

And traditional cladding materials, such as cladding materials made of beryllium gold mixed graphite, uranium 238 and other materials, are highly toxic both in themselves and in the smelting process because of beryllium gold. If you are not careful, it will be a major casualty accident.

And this zirconium oxide carbon composite material, there is no problem in holding it in your hand.

In addition, it can also be used in some high-tech fields such as nuclear energy, rockets, military industry, aerospace, etc.

Top-level materials are like this, even if the use requirements are limited, they can be used in many fields.

Hearing what Xu Chuan said, Zhao Guanggui, who was too excited, gradually calmed down.

He smiled and said, "Academician Xu, you are really too demanding of yourself. To be honest, if I had independently developed this material before, I would have held a banquet for three days and three nights to celebrate."

"This material is enough to publish two or three top SCI journals."

Speaking of this, Xu Chuan smiled and shook his head, then remembered something, and continued: "Oh, by the way, you mentioned this, there is another thing."

"Academician Xu, you say." Zhao Guanggui replied quickly.

Xu Chuan tapped his fingers on the table and said: "Regarding this material, from the neutron irradiation test data over at Daya Bay, you also know that it has great application potential in the first wall of the controlled nuclear fusion reactor."

"So for now, before our controlled nuclear fusion is completed, or before it is completely confirmed that this material cannot be used for the first wall material, the relevant papers cannot be made public for the time being."

Xu Chuan opened his mouth, and Zhao Guanggui probably guessed what the big man in front of him meant.

In fact, this is nothing. Whether in universities, national laboratories, or private research institutes, as long as the research results, such as patents, are completed by these contracted units, they basically belong to the research institutes and laboratories.

These are industry practices whether in the materials industry or in other fields, and they will be stipulated in the contract, and there is nothing to dispute.

As for the researchers who made this achievement, they generally get project bonuses and one or more papers written during the research process.

Of course, if it is those top-notch experts, such as Academician Xu in front of him, if he is invited to a private research institute or university to participate in a project, he has the opportunity to get a share of the results.

That is, he can get a share of how much the results are sold.

Generally speaking, it ranges from 1% to 10%, depending on the contribution, reputation, status and other things made by the researcher.

But many times, especially for researchers like him who have participated in national key projects. After making achievements, considering the confidentiality of the project, patents, and other related projects, the papers may be held in their hands and postponed for a period of time before being published.

Or sometimes it may even be impossible to make it public or even apply for a patent.

However, for most scholars and researchers, especially in China, papers are their hope, the materials and tools they use to build bridges and climb up, and their qualifications!

Whether it is promotion or job title evaluation, such as upgrading from associate researcher (deputy senior) to researcher (senior), what is needed is top SCI papers.

But there is no way. Many times, especially when working on confidential projects, in order to avoid providing help to competitors, papers on experiments or projects that have significant help are generally delayed or suspended or only published in a confidential form in China until the end of the project, and there is a chance to be completely disclosed.

Although the paper is not a complete experimental data and report, it only records part of the data and related information, but these things are enough to provide competitors with a feasible idea.

Of course, when such a situation occurs, research institutions or laboratories usually compensate the relevant researchers.

It is more common to give more bonuses after the project is completed, and approve more research funds for the next project.

In addition, there are more awesome rewards. He had a colleague before, who also followed an academician to do material research and development. After the work was done, he found that the materials had entered confidentiality and the written papers could not be made public.

Then the academician directly gave him the two materials papers he had made.

The result was a top SCI paper in exchange for two top SCI papers.

For a scientific researcher, this kind of thing is probably a blessing from heaven.

After all, many times, the evaluation of professional titles or promotions depends on the number of your papers and the level of the journals.

At the same level, one paper in exchange for two papers, isn't this pie in the sky?

To be honest, if possible, Zhao Guanggui also wants this!

Of course, if it really doesn't work, it is acceptable to give more bonuses and postpone the publication of the paper.

After all, it is a research paper produced in a super project like controlled nuclear fusion, and it is in the field of first-wall materials, so its influence is naturally great.

Of course, these compensations are actually based on a good trend, or meeting a good boss.

Sometimes, if you are unlucky and meet a bad leader or boss, then it will be a pitfall.

What young people, don't be so utilitarian, it's just a paper. Anyway, you still have so much time to do scientific research later. As a person, you must have a collective spirit of dedication and know how to be grateful. The institute has paid you a salary, bonuses, clothes and housing for so many years, and so much scientific research funds are given to you just because it's just a paper. Are you wronged?

What young man, go back and work hard, the laboratory will not be wronged in the future, don't spend your mind on fame and fortune.

To be honest, this kind of thing is actually good.

More seriously, they directly take your first author and the paper you wrote, give you a second author, and then there is no bonus and performance, and if you talk back and expose it, you may be fired directly.

These phenomena are also real in the academic circle.

Of course, Zhao Guanggui is not worried about this happening in front of this man.

In the eyes of this big man, what is an SCI?

Computing is a top SCI paper such as "Nature" and "Science", which is nothing in the eyes of this big man.

After all, don't you see how many top world problems he has solved.

He solved two of the seven millennium problems in the field of mathematics alone.

What he is more concerned about is how this big man will compensate him with his generosity.

Across from him, Xu Chuan saw the expectation on his face, smiled, and said, "Don't worry, the relevant compensation results will not disappoint you."

"Whether it is a material bonus or related honors, you will not be treated unfairly."

"Including the paper, for now, my personal opinion is to postpone the publication, but it needs to be discussed later. If it is confirmed that this paper cannot be made public, the institute will compensate you with at least two top SCI papers in the field of materials. You can write your name as the first author and the corresponding author, and it will be counted as your independent research."

Hearing this, Zhao Guanggui's eyes lit up and he blurted out, "I am willing to obey the arrangement!"
