The military-industrial scientific research system of the academic master.

Chapter 1357 Identity Reversal (New January, please give me a monthly ticket~)

In fact, the reason why Chang Haonan initially focused on the Faraday generator was because the combustion chamber-nozzle structure of the scramjet engine is inherently a Faraday channel, which can be used as a power generation channel with almost no additional modification.

But now that it is facing other application scenarios, corresponding adjustments must be made.

Peng Juexian couldn't hold back after hearing this:
"Academician Chang, your design has two main parts, one is the plasma generation system, and the other is the plasma power generation system. Now they are all replaced... Is this nuclear battery really a sudden inspiration?"

Chang Haonan thought about it and found that it was indeed the case.

The detonation stage is replaced by a reactor, and the Faraday generator is replaced by a Hall generator.

It's like a redesign.

However, he still answered very seriously on the surface:

"The principle verification equipment... you know, it is completely different from the final application equipment, which is normal..."

Peng Juexian did not make any further comments, but just glanced at Chang Haonan suspiciously.

It is true that the prototype is a very early stage, but it is not particularly common to say that the engineering stage and the prototype stage are completely different.

What's more, that usually means that researchers have not yet built a complete picture of the entire project in the principle exploration stage.

For example, China's first-generation power nuclear reactor was halfway through exploring the principles and was found to be unworkable, so it was finally changed to copy and upgrade based on the OK150 pressurized water reactor.

Later, they realized that the original idea was feasible, so they developed the second generation of products independently, resulting in almost no direct technical connection between the first two generations.

But this is obviously not the case.

The previous full system design diagram can be said to be just a concept.

But you have already thought out the design of the disk generator, and you are telling me that it is still in the principle stage?

Pooh!
Only a ghost can believe it!

Of course, he didn't have to argue with Chang Haonan over such details, but he just quietly raised the priority in his heart -

I was originally planning to think about it myself after returning, but now it seems that I have to at least arrange a group of people to follow up.

Otherwise, you might not be able to keep up with the other party's pace one day.

"My research group has done some research on disk-type Hall power generation. Based on the current results, we can determine that when the channel electrode adopts convex expansion, the boundary layer can be effectively suppressed, so the power generation performance is the best. We can further improve on this basis. As for the subsequent flow part, you are an expert, so I won't teach you how to do it..."

"..."

After the confrontation, although Peng Juexian was frightened, he did not lose too much face as he was unprepared and was attacked first, and he maintained the dignity of the academician team.

At least he was satisfied with the result.

So I'm ready to wrap up this trip:

"Then Academician Chang, after I return, I will have people prepare the materials and work with you to perform physical and thermal calculations on the core to see if we can secure an opportunity to build a ground-based verification reactor... To be honest, if it were in other fields, the risk would be a little higher, and at most we would lose some funds. But as you know, when it comes to nuclear issues, our superiors have always been more conservative..."

"I have also considered the risks of the project."

Chang Haonan said seriously:
"The high-temperature gas reactor used for power generation is not yet mature, and it is indeed a bit radical to directly use a helium/xenon mixed working fluid on the ground..."

Peng Juexian's eyes were instantly filled with vigilance:

"Let me make it clear that the HTR-10 high-temperature gas-cooled test reactor is the seed of our country's future fourth-generation nuclear power. It is a project directly supervised by the decision-makers and must not be converted for other purposes..." Chang Haonan felt a little amused after hearing this, thinking that his image seemed to be developing in a strange direction.

He quickly explained:
"Don't worry. I'm not going to touch the HTR-10. Besides, the pebble bed module high temperature gas-cooled reactor still generates electricity by boiling water, which doesn't meet the requirements of the nuclear battery concept... I want to ask, can we consider improving the existing isotope production reactors or those that are about to be phased out as plasma generators?"

Peng Juexian, who had already stood up, sat down again.

"This……"

He frowned and thought.

In addition to generating electricity, another use of nuclear reactors is to produce radioactive isotopes. Since these research reactors are generally small in scale and have special uses, gas cooling technology was used earlier than power generation reactors.

If it can be improved on this basis, it can indeed become a pilot-level plasma source.

Moreover, he could also bring in Chang Haonan as an external aid to help him solve a problem that has been bothering him for a long time.

On a larger scale...

Such a crazy plan can probably only be tested in space.

Anyway, there is no nuclear radiation in outer space. We just need to make sure this thing can fly farther and farther and not fall back to the earth.

Thinking of this, Peng Juexian nodded:

"There is indeed a low-power research reactor in Jincheng. It was built in the early 90s specifically for the production of californium-252, actinium-225, and strontium-89. However, the design was too conservative and the production capacity was insufficient, so we have always wanted to shut down the reactor and build a larger one, but we have never been able to find a good reason..."

How could Chang Haonan not understand what the other party meant?
"Nuclear batteries can provide a convincing enough reason. I will prepare the report, and Academician Peng can just sign it when the time comes."

The two sides hit it off immediately, and Peng Juexian was feeling very happy:

"Then there are some specific technical issues. The reason why small-scale research reactors can use gas cooling early is because the outlet temperature is relatively low, generally only around 1000K, which is still some distance away from the indicators in your plan."

"As for the fission reaction, it's not difficult to simply raise the temperature. But if you want to control it after the temperature is raised, you not only have to upgrade the coated particle fuel technology, but also replace the corresponding pressure vessel, core support structure, and intermediate heat exchanger. Now, in terms of high-temperature resistant metals, your Aviation Power Group is the best in the country. You see..."

Chang Haonan suddenly revealed a relieved smile——

Ten years ago, when he was just reborn and was still a minion, he also met his needs by borrowing resources from other people's projects.

The scene today is almost a replica of that time, except that he has become the one whose resources are being used.

He even had his resources taken advantage of by an academician.

Of course, he didn't mind this situation, so he took the initiative to say:

"At higher operating temperatures, metal materials will creep, resulting in reduced strength, and this behavior is usually unpredictable... Therefore, metal materials alone, even nickel-based alloys with strong high-temperature resistance, are unlikely to withstand an environment of 2000K or higher for a long time. They also need to be combined with thermal insulation coatings and some active cooling methods..."

"But Academician Peng, you don't have to worry. Although these technologies are not ready-made for us, we can modify them based on the turbine blade design and apply them to your high-temperature gas-cooled reactor project."

For scientific researchers who can become academicians, in addition to having good skills, qualifications and a good network of connections, thick skin is also an indispensable factor.

Therefore, after Chang Haonan pointed out his true intention, Peng Juexian shook hands with the other party without blushing or getting nervous, as if nothing had happened:

"So... are you happy to work together?"

"Pleasant to work with."
