Technology: The first development of a sixth-generation fighter

The name of the paper at the top of the “Yanda Core” forum is not long or short.

The title of the paper is “Graphene-based Cooling High Temperature Air-cooled Reflection Reactor Effectiveness Conjecture of Neutron Moderator”.

The time of posting is 14:03 noon.

At 14:04, it directly passed the review of the editorial team of “Yanda Core”.

And it is officially pinned.

By the evening, hundreds of thousands of “thumbs” and reviews had been harvested.

It should be known that “Yanda Core” is a first-class professional scientific research forum in Longguo.

The number of people concerned is also the domestic scientific research workers.

Ordinary viewers unless they are lovers of depth.

I don’t even know about this forum…

Therefore, the author of this paper can get hundreds of thousands of likes and comments in a few hours, which can be said to be strong enough to explode!

Although it has something to do with the top of the forum.

But it is certainly inseparable from the absolute hard power of the authors.

Jiang Chen is just preparing to start developing a fifth-generation nuclear submarine, and this paper is related to the high-temperature gas-cooled reflector.

Isn’t there a similarity between the two sides?

So Jiang Chen curiously clicked on this anonymous publication of “Graphene Cooling Based on High Temperature Air Cooling Reflection Reactor Neutron Moderator Effectiveness Conjecture”:

“The operating temperature of the high-temperature gas-cooled reactor is above 1000 ° C, and graphite is the only moderation, reflection and structural material that can be used.

Radiation damage from graphite plays a decisive role in the techno-economic performance of reactors, especially spherical bed high-temperature gas-cooled reactors. As mentioned earlier, the mechanisms of neutron moderation and reflection are both elastic scattering. The out-of-alignment energy of the carbon atoms in the graphite lattice is 25eV, and when the energy transmitted during elastic scattering is greater than 25eV, the carbon atoms will be knocked out of the lattice node, forming a vacant, gap atomic pair…

Irradiation damage is mainly manifested as the accumulation of energy storage (Wigner, potential), for example, room temperature irradiation storage energy up to 2720J / g, if instantaneously released, can make the temperature rise sharply 1350 °C caused by accidents…

The boron content in the raw material impurities is low, because the boron content of 1×10 is equivalent to increasing the cross-section of lmb, and most of the metal impurities of high-temperature graphitization volatilize at 2800~3000 °C, and boron is higher than 3000 °C is also difficult to remove, because boron and carbon form B4C3…”

…………

Below the paper, it’s almost all a cheering rainbow fart.

“Sleeper!

At first I thought it was a new person’s paper.

Click in and take a look to know that this is the paper of the real big guy! ”

“That’s not it, this academic achievement, theoretical understanding, coupled with fine experimental data, I have to suspect that this author is an academician who is developing a high-temperature gas-cooled reactor!”

“At present, the domestic researchers of high-temperature gas-cooled reactors are basically the top bearers of the physics business of the nuclear industry, blindly guessing a professor of nuclear physics Chen Fanglin of Yanda!”

“No, Professor Chen’s writing style is not so rigorous…

And Professor Chen will not use the behavior of the forum to publish papers in the “Yanda Core”.

Others are in Yanda, can’t they give it directly to the editorial department? ”

“Then it’s Professor Su Chengxiao of Dragon Science and Technology?”

“Farewell, big brother, Professor Su is only in his 50s.”

The age of the authors of the papers has been marked as 75…”

“It seems to be saying that Ha…”

“Why do you have to dwell on who the author is?

Is the author a beggar, and this paper is not excellent? ”

“Give the author a big crazy call, the writing is great, and look forward to the early development of high-temperature gas-cooled reactors!”

………………

Although the author of the paper does not have a real name.

But everyone’s point of view is also obvious, that is, take the toe to think that this paper must be issued by an academician-level big man who studies nuclear reactors!

Without exception, they all applauded the article “Graphene-based cooling high-temperature gas-cooled reflection reactor effectiveness of neutron moderators”.

But Jiang Chen frowned slightly after reading the paper.

The paper is indeed well written!

The understanding of high-temperature gas-cooled reactors is also very profound.

If it were not for the elders who had been invading this way for many years, it would have been impossible to write such a deep understanding.

But because high-temperature gas-cooled reactors are new technologies.

Perhaps the senior’s experimentation on high-temperature gas-cooled reactors was not enough.

As a result, several minor bugs appeared in the paper.

Out of a responsible attitude towards scientific research.

Jiang Chen decided to help the old man point out the mistake.

“The previous papers were written in great depth, but in my opinion there were a few minor errors in direction:

(1): The author pointed out in the article that the boron content of 1×10 is equivalent to increasing the cross-section of lmb, and most of the metal impurities of high-temperature graphitization volatilize at 2800~3000°C, and boron above 3000°C is also difficult to remove…

However, there is a certain error in the prediction of the boron content in the raw material, and I think the boron content should be around 13.3291% is the best…

(2): Nuclear graphite should have a high density, generally speaking, it needs to be controlled at about 1.79/cm to meet the operation requirements of graphite reactors…

(3): When graphite is used in nuclear reactors, due to thermal expansion caused by temperature rise and irradiation caused by Wigner growth, so the anisotropic expansion of graphite in the structure of the moderated layer formed by the accumulation of many graphite blocks cannot be ignored…

(4): The graphite deceleration layer and the reflective layer are made of finished block stacking, so that nuclear graphite processing requires higher precision than any graphite product processing. In fact, it is required that the accuracy be best controlled within 1 wire…”

………………

Four bug suggestions to help authors correct errors are left behind.

Jiang Chen closed the interface of the paper.

He did not come to the forum of “Yanda Core” specifically to correct the mistakes of the above scientific research netizens.

He still has to complete the task of 4 core journals given by Mu Shijun!

I opened the submission box.

Four papers on nuclear physics were successfully completed in 4 hours!

After all, it’s LV.3’s big guy.

The academic achievements of physics have long been academicians + levels, and the four papers are not sprinklers?

After exiting the Yanda core, Jiang Chen directly lay on the bed and began to sleep.

His user priority is definitely the most garbage.

Wait until the editor has reviewed his paper, and then decide whether to publish it or not, and then go tomorrow.

He wasn’t waiting here for a while, and it was comfortable to walk into sleep.

Jiang Chen slept comfortably.

The long comment he left behind has attracted widespread attention in “Yanda Core”!
