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 magnetic fluid 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 that possible... no matter what, you have to wait for the new production base to start construction, otherwise it will be troublesome if something happens if something happens."


    Most of China''s radioisotopes 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 independent 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 just in charge of introducing the reactor stood up from a computer on the console:


    "Academician Peng and 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."


    Hearing this, Han Chenfeng instantly understood the answer to his question just now.


    Before the other party could say more, he took the lead:


    "You can take it slowly from the export. I will first determine some of the key parameters, and it is also necessary 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 remove or modify this part of the device first."


    As far as the entire power system is concerned, 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, just remove the steam turbine. The steam circulation loop can be kept first, and by the way, use relatively low-density ion flow to verify the control problem of the external magnetic field..."


    While speaking, 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.


    "Yes, but yes..."


    Peng Juexian''s tone was a little confused:


    "But when I went to Huairou Science City before, didn''t I see that you have all verified these?"


    "It has been 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 plasma advantage of nuclear reactors through the excitation gas is that they are durable, but the conductivity is much weaker than the shock tube solution, and more needs to be applied The strong external magnetic field, and considering that the core must fluctuate during continuous operation, at least a part of the electromagnetic field needs to be applied outside the permanent magnet to maintain the stability of the magnetic fluid itself…”


    “…”


    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:


    "That means to install an additional set of…or multiple sets of coils?"


    This 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 coils…”


    Peng Juexian lowered his head and stared at the tip of the anti-static boots, thinking, as if he had thought of something.


    After a while, I looked back to the console:


    "Old Han, when will you hold a technical analysis meeting include the design of this control coil, remember to 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 it is said that nuclear involvement is nothing small, from a common sense, as long as the core and steam circuit transformation is not involved, the project volume will generally not be 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 information from his laptop:


    "Many materials are still being compiled, 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 long expected this situation:


    "It doesn''t matter, I''ll see what 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 magnetofluid is recycled water with partial ionization seeds, rather than plasmas with high temperature and high pressure, so you can put this part..."


    However.


    It seemed as if fate intended to target Han Chenfeng.


    Halfway through his speech, he heard a sirens coming from the work area in the distance.


    He stuck the last word "heart" into his 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.


    Sure enough, Han Chenfeng also reacted:


    The newest ⊥Xiao⊥Speak⊥Send⊥Six⊥9⊥Book⊥⊥⊥⊥Back⊥⊥⊥⊥!


    "As planned, what is being conducted now is the interaction test of the disturbed magnetic field and plasma. It should be that some problems have occurred in the magnetic field. I will deal with it immediately..."


    That being said, there was still a little embarrassment in his tone.


    "Wait a moment!"


    Chang Haonan called out from behind:


    "I''ll go and see with you."


    He was ordered to ban the radiation area of ??the nuclear reactor at the beginning of the project, but if it was only the end of the second circuit, the radiation level should be completely below the safe dose unless the steam generator pipeline ruptured and caused 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 the out-of-control ion current distribution..."


    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, I wondered why a strange face appeared, and then glanced at the pass hanging on the other person''s chest...


    The guy stood attentively.


    "Academician Chang...Academician Chang?"


    As for this big shot behind the project, he has always been only known but not known anyone before.


    Now that I suddenly saw the truth, I was naturally shocked.


    "Um."


    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 made?"


    In his previous report, he saw Han Chenfeng''s coil design, 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, and was installed behind the upper and lower plates of the disc generator near the plasma channel. , it is a relatively safe design among magnetic constraint devices.


    If you can see the corresponding magnetic field structure, you may quickly analyze the specific problem.


    "It''s being done, it should be soon..."


    The young engineer followed suit, and an image covered with red and black data points was quickly displayed on the other screen next to him.


    "The 1D results and 2D results are both on this picture, and the rest needs further analysis."


    Chang Haonan had already sat in front of the computer at this time and had 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:


    "Like the distortion of the boundary magnetic field topology caused by three-dimensional magnetic field disturbance..."


    Before people around him could ask questions, he quickly gave new instructions:


    "The reason is not yet clear. I need the resonance perturbation spectrum corresponding to the working state when the alarm occurs, the Poincaré diagram of the magnetic field topology and the magnetic footprint diagram in the disc power generation channel!"
