Chapter 1381 The first step to the sun
Han Chenfeng blinked without replying.
The other party said it was "struggle", but since the decision to stop the pile and renovate has been made, even if there has not been a clear result, it must be more optimistic.
He only needs to play a role in the magnetofluid generation and control part that he is relatively good at. "So...the reconstruction project will start right away?"
Peng Juexian reached out and held his forehead, and his face under the mask showed an expression of indulgence:
"How is it possible... no matter what, you have to wait for the new production base to start construction, otherwise the window period will be so long. If something happens, it will be troublesome."
Most of China's radioactive isotopes rely on imports, and there are very few categories that can be supplied by themselves.
But even so, there is a gap between whether there is self-production capacity or not.
Han Chenfeng thought it was right, and he was really a little too anxious, so he calmed down slightly:
"That's it this time..."
At this moment, the technician who was in charge of introducing the reactor just now stood up from a computer on the console:
"Academician Peng , Director Han, all the operating records of this pile in the past five years have been retrieved, but because the equipment is relatively old, it may take a long time to export all the records."
Listen At this point, Han Chenfeng instantly understood the answer to his question just now.
Before the other party said more, he took the lead:
"You can take it slowly from the export. I will first determine some of the key parameters, so as to have a number of the scale and direction of subsequent reconstruction work." Peng Juexian nodded with satisfaction and added: > "In addition, although the core operation cannot be stopped, Plant 504 has achieved 100% power supply of gas turbines since last year. The attached steam power generation facilities are no longer necessary. It has been maintained for the sake of reducing costs. If you need it here, you can dismantle or modify this part of the device first. "
In terms of the entire power system, the power provided by a small test reactor is minimal, and the cost of connecting to the power grid cannot be repaid.
But for this factory, because it is necessary to ensure that production is maintained under the condition of interruption of external power, and the reactor itself also needs to be circulated and cooled, it is not useless.
But now that we have more important uses, we naturally have to go back.
"If this is the case, then just remove the steam turbine. The steam circulation circuit can be kept first, and by the way, use relatively low-density ion flow to verify the control problem of the external magnetic field..."
Speak During this time, Han Chenfeng had already sat in front of the computer just now and began to quickly search the part of the parameters he wanted on the page.
"However, it's OK..."
Peng Juexian's tone was a little confused:
"But when I went to Huairou Science City before, didn't I see that you have verified these?"
"I have verified, and we even compiled a preliminary calculation program..."
Han Chenfeng kept turning the page, and at the same time he took some attention and replied: "But on the one hand, there are certain differences in the specific situations of disc engines and pipe generators. On the other hand, the nuclear reactor passed The advantage of plasma generated by the excitation gas is that it is long-lasting, but the conductivity is much weaker than the shock tube solution, and a stronger external magnetic field is required. Considering that the core must fluctuate during continuous operation, it is necessary to at least the permanent magnet. Only by applying a part of the electromagnetic field can the stability of the magnetic fluid itself be maintained..."
"..."
Like most engineers, whenever they talk about what they are good at, they are prone to being unable to stop the car.
Fortunately, Peng Juexian was interested in all novel forms of power generation, so although not everyone could understand it, he was very interested in listening.
After the other party finished speaking, he paced back and forth for a while: "It means to install an additional set of... or multiple sets of coils?"
This The question is a bit too basic, so Han Chenfeng was stunned for a moment, then remembered to answer:
"In general, this is definitely the case. The disturbed magnetic field generated by the active control coil is helpful to the control of various magnetic fluid instability, but different magnetic fluid fluctuations characteristics have different requirements for the disturbed magnetic field position shape, so To achieve accurate and efficient control, you need to make targeted designs for the coil..."
Peng Juexian lowered his head and stared at the tip of the anti-static boots and thoughtfully, as if he had thought of something. .
After a while, I looked back at the direction of the console: "Old Han, when will the technical analysis meeting be held, please remember Call me."
After saying that, perhaps because he was worried that the other party would misunderstand, he quickly added:
"Don't worry, I'm just attending the audience and will not interfere with your decisions on power generation modules..."
...
Although there is no small matter in nuclear matter, from a common sense, as long as it is It does not involve the transformation of core and steam circuits. The project volume is generally not particularly exaggerated and the risks are usually more controllable.
Therefore, the entire solution design and the production and installation stage of the active control coil are carried out quite quickly.
When Chang Haonan suddenly came to Factory 504 in mid-August to inspect the progress, the entire resonant magnetic disturbance coil and the corresponding power supply system had entered the debugging stage.
"I thought you would come in September, so I didn't have time to prepare in advance." Han Chenfeng said while sorting out the information from his laptop: "A lot of the materials are still there. During the compilation process, and because the trial operation has just begun, some operation data are also vacant..."
Chang Haonan also knew what was going on during the project, so he had already had this situation. Expected: "It doesn't matter, I'll see whatever I have. Just make sure the plan is being promoted normally..."
In fact, according to his original plan, he did have to wait until the third test of "Xuanniao" in September, but the superiors considered that the hosts conducted weapon tests during the Olympics, even for medium and short-range ballistic missile tests used for cover-up. Ejaculation is really shady, so it is recommended that he push the schedule back for a month. "That's basically it."
Han Chenfeng pushed the computer in front of Chang Haonan:
"The current work does not involve the reactor itself, even the magnetic fluid All of them are circulating water with partial ionization seeds added, instead of high temperature and high pressure plasma, so you can put this piece..."
However.
It seemed as if fate intended to target Han Chenfeng.
At halfway through his speech, he heard a sirens coming from the work area in the distance.
I stuck the last word "heart" into my throat.
Chang Haonan was also shocked at first. Looking in the sound, he vaguely saw several technicians wearing work clothes moving quickly towards the direction that was originally a turbine unit.
According to the design planning in front of us, there has been replaced by disc generators and active control coils at this time.
It shouldn't be a big problem.
Asolutely, Han Chenfeng also reacted at this moment:
The newest⊥小⊥小⊥小⊥小⊥小⊥小⊥小⊥小⊥小⊥小⊥小⊥小⊥小⊥小⊥小⊥小⊥小⊥小⊥小⊥小⊥小⊥小⊥小⊥小⊥小⊥小⊥小⊥小⊥小⊥小⊥小⊥小⊥小⊥小⊥小⊥小⊥小⊥�
"As planned, what is being conducted now is the interaction test of the disturbed magnetic field and plasma. It should be just that some problems have occurred in the magnetic field. I will deal with it immediately..."
With that being said, He said, but his tone was still a little embarrassed.
"Wait a minute!"
Chang Haonan shouted from behind:
"I'll go and see with you."
He was taken at the beginning of the project The order prohibits entry into the radiation area of the nuclear reactor, but if it is only the end of the second circuit, the radiation level should be completely below the safe dose unless the steam generator pipeline breaks and causes the first circuit to leak.
Han Chenfeng hesitated for a moment, but he really had no reason or courage to refuse, so he had to agree.
A few minutes later, the two walked into the work area with yellow and black signs on the door. "What's the situation?" Han Chenfeng couldn't even breathe and asked as soon as he entered the door.
The staff next to them have a very stable mentality: "The magnetic field pattern generated by the dynamic resonant magnetic disturbance coil is somewhat different from the previous expectations, especially when approaching the current limit, which leads to Ion flow distribution is out of control..."
If it is a serious magnetofluid closed-loop power generation, this is a very serious problem, so a very high alarm level is set in the system.
However, during this test, there was no danger at all.
It was not until after the answer that the engineer turned around and saw Chang Haonan behind him.
First he wondered why a strange face appeared, then glanced at the pass hanging on the other person's chest...
The young man immediately stood attentive.
"Academician Chang...Academician Chang?"
For this big shot behind the project who can be said to have promoted the entire project, he has always been only known but not recognized.
Now I suddenly saw the truth, I was naturally shocked.
"Yes."
Chang Haonan nodded, responding to the other party, and then came to the front of the console on his own:
"Has the magnetic line tracing result been obtained?"
He saw Han Chenfeng's coil design in his previous report, which was divided into two columns, arranged in an annular direction, and was symmetrically distributed on the upper and lower sides of the middle plane. , installed behind the upper and lower plates of the disc generator near the plasma channel, is considered a relatively safe design in the magnetic restraint device.
If you can see the corresponding magnetic field structure, you may quickly analyze the specific problem.
"It's been done, it should be very fast..."
The young engineer said the truth, and a red and black data point was quickly displayed on the other screen next to him. image.
"The 1D result and 2D result are both on this picture, and the rest need further analysis."
Chang Haonan has already sat in front of the computer at this time and has no time to reply.
Han Chenfeng quickly waved his hand to prevent others from disturbing the former's ideas.
About a few minutes later, Chang Haonan spoke in an uncertain tone: "It's like the distortion of the boundary magnetic field topology caused by three-dimensional magnetic field disturbance..."
< br>
Before people around me asked questions, a new instruction was quickly given: "The reason is not yet clear. I need the resonance disturbance spectrum corresponding to the working state and the magnetic field topology structure of the magnetic field when the alarm occurs. Figures and magnetic footprint diagrams in disk power generation channels! ”
