Huaguo

In the capital, in the building on the north side of Chang'an Avenue, an old man who has lived here all the year round reached out and took a letter from the guard.

When he heard that the letter was written by the person who was far away in Jinling, even if it was him, the corners of his mouth couldn't help but move.

So fast.

Is there no money again?

To be honest, it's not a problem for the elderly to feel this way.

After all, every time that person wrote to him, he asked for money.

So much so that when he heard that the letter was written by that person, he couldn't help but think of it.

But no matter how you say it, the letter still has to be seen.

The envelope was opened, and the old man took out the letter paper from it.

The letter paper is very thin, only two pages, which makes the old man slightly surprised, it seems that maybe he didn't come here to ask for money this time?

His eyes fell on the letter, and after a short pause, the old man's pupils contracted slightly, and after briefly reading the contents of the letter, he quickly got up with the letterhead and rushed to the Academy of Sciences.

On the other side, Jinling.

Three days have passed since the completion of the high-energy neutron irradiation experiment.

With the efforts of the researchers of the Computational Materials Laboratory working overtime 24 hours a day, the testing experiments related to zirconia carbon composite materials have finally been completed.

After getting the detailed test report, Xu Chuan carefully flipped through it.

On the whole, the parameters and properties of zirconia carbon composites are in line with the results calculated by his previous image-only model.

There must be numerical deviations or something, after all, it is a calculation of imagery, but the deviations are within the range allowed by the standard.

Comparatively speaking, the results of the test are undoubtedly quite good.

Theoretically, there is no problem with using this material as the first wall material and structure in the chamber of a controlled nuclear fusion reactor.

Of course, it is not known what will happen to this first-wall material that has been subjected to high temperatures, strong radiation, and neutron irradiation produced by deuterium-tritium fusion for a long time.

These require real experimentation to know.

However, Xu Chuan is very confident in this material, he believes in his atomic cycle technology, and he also believes in the efforts of Zhao Guanggui and other researchers to achieve this.

Putting down the test report in his hand, Xu Chuan turned on the computer in his hand, and just wanted to deal with the email, Gao Hongming knocked on the door and walked in, and also brought a reply from the high-level.

There was no letterhead, no red-headed documents or anything.

There is only a sentence relayed by Gao Hongming himself.

[No problem, the state will fully cooperate with your work. 】

In a word, it brings not only high-level opinions and affirmation, but also funding and related policy support.

Even though Xu Chuan did not mention anything related to funding in this letter, the central government still supplemented the funds to the account of Qixia's controllable nuclear fusion project according to the standard of 20 billion yuan.

It has to be said that the solution of the first wall material and the construction of the demonstration reactor have allowed everyone at the top to see the real dawn and hope.

Everyone is looking forward to the spark being the first to light up on this land of Shenzhou.

On the other hand, Jinling Municipal FU then received instructions to fully cooperate with the work of the Qixia controllable nuclear fusion project, not to mention the military qu, and the military also reassigned a regiment-level force to comprehensively strengthen the security work of the Qixia controllable nuclear fusion engineering base.

These are all implemented with Gao Hongming's return.

The next day, a working group arranged by the Huaguo Nuclear Industry Construction Group rushed to the engineering base at 9 a.m. led by two academicians in different fields.

The two academicians who led the team were Academician Wang Yongnian in the construction of nuclear power plants and Academician Hou Chengping in the science and technology of the nuclear industry.

These two academicians are top experts of the nuclear industry construction group, who have worked in the nuclear industry for many years, have rich experience in the design of fission reactors and nuclear power generating units, and have cooperated with each other to preside over the design of Qinshan Phase I, 23, Sanmen and other well-known nuclear power plant projects.

Including the fourth phase of nuclear power plant technology currently under development in China, these two are also the foundation leaders.

Xu Chuan and Peng Hongxi greeted the two academicians in the office, and although it was the first time for the group of four to meet, the atmosphere was quite harmonious.

"I heard that Academician Xu, you are going to build a demonstration reactor here, and several academicians of our nuclear industry group almost didn't fight in the conference room in order to grab this quota for leading the team exchange."

Compared with Academician Wang Yongnian, who is in charge of nuclear reactor construction, Academician Hou Chengping, who is in charge of the technical design of the nuclear industry, is a few years younger and more active, laughing and joking in the office.

But there's nothing wrong with what he's saying.

Two days ago, when the nuclear industry group held an emergency meeting, they were surprised to hear that they were involved in the construction of the demonstration reactor on the side of the Daybreak fusion device.

Demonstration reactors for controlled nuclear fusion, for most people in the nuclear industry group, are just something that exists for an unknown number of years.

After all, in terms of the development of controlled nuclear fusion, it is not known how long it will take to achieve it.

Fifty years forever is not unreasonable, and there are too many problems to be solved to achieve controlled nuclear fusion technology.

Even after two hours of high-density plasma operation before the Qixia Controlled Nuclear Fusion Project, most people still think that it will take a long time for controlled nuclear fusion to be realized.

It's almost unlikely, at least for the next five years, and there may be a glimmer of hope under that man's leadership in ten years' time.

However, they were told that the Qixia Controlled Nuclear Fusion Project was about to start the construction of a controlled nuclear fusion demonstration reactor, and the nuclear industry group needed to arrange manpower to go over to assist the other party.

Not only that, at the meeting two days ago, the president of the group, who presided over the meeting, also announced on the spot that he would completely suspend the research and development of the fourth and fifth generation nuclear fission power station technology.

This surprised them even more.

You must know that after solving the problem of difficult disposal of nuclear waste, the technology related to nuclear fission power stations has ushered in the most vigorous development stage in the history of China.

Not only all kinds of funds, but also government support, even the fifth-generation controllable nuclear fission technology, which was originally planned to be launched in 2025, has been arranged in advance, with projects approved and researched by scientific researchers.

However, at the meeting just two days ago, the CEO of the nuclear industry group personally announced that he had completely suspended the research and development of the fourth and fifth generation nuclear fission power generation technology.

Nuclear fission technology, which was still thriving in 2020, seemed to be swept into the dust of history after a year, catching everyone off guard.

But at the same time, the news also got everyone excited.

After all, it's controlled nuclear fusion.

In the office, Xu Chuan took out the tea leaves brought by the old man last time, made a pot of tea himself, and said with a smile: "The construction of the demonstration pile this time will have to trouble the two academicians." ”

Academician Wang Yongnian took the tea, put it on the tea table in front of him, and said with a smile: "Academician Xu is too polite, this is our job, there is nothing troublesome and troublesome." ”

After a pause, he landed on Xu Chuan with a curious gaze and asked, "Can I ask curiously, can I ask the progress and situation of Dawn here?" ”

On the side, Academician Hou Chengping also cast a curious gaze.

The research progress of Qixia's controllable nuclear fusion project is kept secret, and the outside world will not know about it unless Xu Chuan announces it. The latest news they know is still the previous two hours of high-density plasma running.

And the academician Xu in front of him started the construction of the demonstration reactor, although it has not yet been officially announced, but it also makes them curious about how far Dawn has gone in the field of controlled nuclear fusion.

Hearing this question, Xu Chuan smiled and said, "We have found a material that is suitable for the first wall. ”

As soon as these words came out, Wang Yongnian and Hou Chengping's eyes tightened, and their eyes and faces were filled with incredulity and shock.

A breakthrough in the first wall material!

It's incredible, it's shocking!

No wonder he directly started the construction of the demonstration reactor.

Although they are experts and academicians in the field of nuclear fission, both of them still have some understanding of controlled nuclear fusion technology.

In controlled nuclear fusion, the most difficult problems are the control of ultra-high temperature plasma turbulence, the resistance of the first wall material to neutron irradiation, and the problem of tritium self-sustaining.

Combined with the operation time of the previous dawn fusion device of more than two hours, in the first two conditions, Qixia's controllable nuclear fusion project has made a breakthrough.

Plasma confinement + first wall material, if tritium self-sustaining is solved, the most difficult core will be solved almost all.

As for other aspects such as temperature control, energy recovery, helium ash removal, safety issues, etc., the impact is not so great.

Not to mention Xu Chuan, even the two of them have no doubt that after these core issues are solved, Huaguo will soon usher in the lighting of the spark of controlled nuclear fusion.
