Chapter 1389 Great gift from heaven


    As usual, an academic exchange forum will be arranged on the first day of the ITER meeting.


    Not only those involved in the project, but also researchers from outside institutions and schools can participate.


    Usually, some prestigious scholars in the field of fusion will be invited to give reports.


    It is the most "lively" part of the entire agenda.


    Of course, high openness often means there is no practical information.


    So Huang Zhitao was originally here to take advantage of the excitement, and even brought a notebook and a recorder.


    As a result, when I heard the end of the first game, I had already put my pen cap on.


    "Teacher Fang, isn''t that right?"


    Finally, he was in the tea break, and he breathed a sigh of relief as if he had been amnesty and turned to look at Fang Jianming next to him:


    "Why are all policy-based things, and there is not even theories related to ITER..."


    Of course, we don’t expect to hear the specific details of the project here, but the development history of Tokamak lasted for more than 40 minutes, and the application prospect of fusion energy is nearly half an hour, which is really challenging Huang Zhitao’s patience.


    The latter looks like it was expected:


    "The first report in the morning was basically like this... I asked an expert who is very famous but has been away from the front line for a long time to talk about some content that is mainly popular science."


    Huang Zhitao frowned:


    "Isn''t this a complete loss... Is this a waste of time..."


    Although no outsiders could understand Chinese at the scene, he still put back the unelegant statement.


    "Well... Scientific research also needs to consider the influence of public opinion."


    Fang Jianming stood up, waved his hand to signal the other party to follow, and then continued to add:


    "Although France accounts for about 80% of its nuclear power proportion, the domestic resistance to nuclear power is not small at all. When it was decided to build the ITER stack in Karadashe, many groups jumped out to oppose it. Of course, the United States and Japan are instigated later, but there are indeed public concerns..."


    "So over the years ITER has been focusing on exaggerating its scientific research attributes and trying to weaken the presence of engineering application level. To put it bluntly, this forum is also part of image shaping... And so many people are welcomed and sent, it will be somewhat beneficial to the local economy and can block some people''s mouths."


    While talking, the two of them had already arrived at the corridor outside the lecture hall.


    "I''ll go..."


    Looking at the various refreshments filled with two long tables in the lobby next door, Huang Zhitao swallowed uncontrollably.


    In 2008, China''s scientific research funds were no longer the same as they were when they were too old to be able to break a penny into eight petals.


    But in terms of enjoyment, it is obvious that there is no way to compare with Europeans.


    Even though it has just been baptized by a financial crisis.


    He suddenly felt that this trip might not have been in vain...


    Although Fang Jianming is a younger generation, he is still in his forties. He can''t eat too many sweets and only takes two bananas:


    "In my experience, the content of the second report may involve the ITER itself, which is usually a specific plan for a certain direction in the next few years. If you are lucky, you may hear some interesting parts."


    Huang Zhitao quickly swallowed the snacks in his mouth:


    “Good luck means…”


    Fang Jianming explained:


    "Except for the first session, the people who gave the report were all internal staff of ITER. In addition to dealing with this errand, they also had to prepare a conference speech a few days later, so some people would be lazy and just delete and modify the ones behind them..."


    Huang Zhitao thought it was right at first, but then he remembered the days when he stayed up late to help the boss change PPT:


    "But aren''t such unimportant reports generally prepared by students?"


    Fang Jianming: "Students can be lazy too..."


    “…”


    In fact, he just said it casually.


    The main reason is that Huang Zhitao lost interest too early. After all, their position is still high, and the impact of slipping away from the account is not very good.


    But when the two returned to their seats, they noticed that the PPT title on the curtain had been changed to -


    The future of ToreSupra Tokamak installations.


    Of course there is nothing to surprise.


    The theme of each round of reports has long been printed on the agenda.


    The key lies in the subtitle below—


    Steady-state superconducting tokamak upgrade in tungsten environment.


    Huang Zhitao''s eyes suddenly lit up:


    "I am worthy of being Teacher Fang, and I guessed it very accurately... If I remember correctly, one of the main contents of our meeting should be to discuss the subsequent upgrade plan of the ToreSupra device?"


    Even according to the current plan, the start of the ITER reactor body will have to wait until after 2010, and the start and generation of plasma will be around 2015.


    Considering the procrastination and disputes that are necessary, the specific time is even more distant. So in comparison, people are paying more attention to a series of existing facilities, including ToreSupra.


    And in fact, these immediately desirable resources are also the biggest credentials for Europe to be confident in hosting the ITER project.


    "Ahem—yes."


    Fang Jian knew that he was just a mistake and was inevitably embarrassed to be so flattered, so he quickly cleared his throat to cover up.


    "It seems that the French should have a relatively complete plan..."


    Soon, the speaker walked up to the podium from behind the curtain, and the noise in the audience immediately calmed down a little.


    …


    Fang Jianming turned his head slightly:


    "This Academician Robert Hull is the actual head of the Institute of Magnetic Constraint Fusion under the French Atomic Energy Commission. We will inevitably deal with him in the next few days. Pay more attention to his speech habits..."


    Huang Zhitao nodded with a serious expression and opened the notebook again.


    "Everyone, since its launch in 1988, the ToreSupra Tokamak device has successfully completed many key technical and theoretical verification tasks, including superconducting magnets and cooling systems, actively cooled plasma wall components, pressurized water circulation equipment, heating and current drive systems, as well as pump limiters and real-time protection control systems, etc...."


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


    The old man is quite old and doesn''t have enough energy, so he doesn''t have much transition, so he just goes straight to the point:


    "In recent years, as the device enters the middle and late stages of its lifespan, we have also received a lot of concern from peers or public opinion, especially about the possible pollution and risks that may arise after life..."


    "But I think the concerns in this regard are unreasonable, because ToreSupra, as a valuable asset in the world''s fusion research, will not be simply dismantled, but will be upgraded to a full tungsten wall superconducting tokamak device (WEST) based on the original device, aiming to provide key technical verification for the international thermonuclear fusion experimental reactor..."


    “…”


    It is obvious that Academician Hull also came with a propaganda mission.


    The theme of the entire report is that the upgrade process is safe, environmentally friendly, and low-cost. After the upgrade, you can fully benchmark mainstream similar equipment such as EAST and JT60SA. Please don’t worry.


    Of course, it is a nominal academic report after all, so it also involves some specific improvement ideas.


    For example, the introduction of all-tungsten filters makes use of the advantages of metal tungsten''s high melting point, high thermal conductivity, low sputtering, low fuel retention and low neutron activation rate to improve the equipment''s high parameter steady-state operation capability.


    There are also new ion cyclotron heating antennas, improved superconducting magnet systems, new online real-time diagnosis and monitoring technology, etc.


    All are news that has been around in the industry.


    This made Fang Jianming and Huang Zhitao a little discouraged.


    But it makes sense to think about it. Others have also struggled all the way, and it is unlikely that they will reveal too much key information before the meeting begins.


    Huang Zhitao was about to close the notebook again when he saw the PPT in front being turned to the back page.


    Above is a schematic diagram of the waveform of the radiation signal in the plasma core.


    Hull on the stage is still introducing the capabilities of future WEST devices, but Huang Zhitao off the stage suddenly stopped.


    "Teacher Fang, look at that picture."


    He gently poked Fang Jianming next to him.


    The latter was also staring at the curtain, but found nothing unusual:


    "What''s the typical serrated oscillation caused by unstable operation of magnetofluids...what is wrong?"


    Although it is unstable operation, small amplitude and high frequency serrated oscillation is conducive to the discharge of impurities in the plasma core, which is not a completely negative phenomenon.


    "no."


    Huang Zhitao shook his head:


    “You look at the coordinates on the vertical axis.”


    Fang Jianming narrowed his eyes and looked at it, but he really couldn''t recognize what the sesame size numbers were.


    Fortunately, Huang Zhitao quickly drew the general style of the picture on the notebook:


    "The data on this picture has been processed specifically by them, so it seems to be very small."


    He pointed to the numbers that were not evenly distributed on the vertical axis and said:


    "So actually, I think they may be facing a big jagged collapse..."


    "Do you still remember the report I asked me to read a few days ago, the one signed by Academician Chang and Teacher Peng?"


    Fang Jianming just suffered a loss in his eyes, and his academic level was still fine.


    I immediately understood what Huang Zhitao meant.


    The specific mechanisms of serrated oscillation and serrated collapse are not clear, but it is certain that the latter is usually accompanied by drastic changes in the topology of the magnetic field, resulting in a large loss of heat and particles in the core, and stimulates a series of other magnetic fluid mechanical instability.


    The report mentioned by the other party just explained and even solved this problem to a certain extent.


    "After this report is over, I will go to Academician Peng immediately and I won''t listen to the third one!"
