Chapter 1384 Take a break from your busy schedule


    When Chang Haonan changed his work clothes, the fluorescent hand on the dial was already pointing to two o''clock in the morning.


    He reached out and pressed the beating temples and stared at the cooling magnetofluid generator set through the observation window.


    The reading of the pressure gauge in front of him is slowly decreasing, and the pointer is shining with a crystal luster under the green warning light.


    Even small nuclear reactors used to produce isotopes cannot work near critical states for a long time.


    Therefore, after determining the problem and giving a phased solution, about half of the core control rods are lowered again and the core returns to normal operation.


    As for subsequent work such as coil shape adjustment and data collection and sorting, they are basically complicated but not difficult parts, and naturally they do not require Chang Haonan''s personal command.


    "Old Chang."


    Just as Chang Haonan left the control room and was about to return to the hotel in the factory to rest, Peng Juexian also quickly followed him:


    "You mentioned just now that you used liquid lithium as neutron shielding. Are you planning to change the cooling fluid from gas to metal?"


    High-temperature gas-cooled reactors and liquid metal reactors belong to two different directions. Although the energy supply principle is the same, there are still many differences in specific projects.


    If Chang Haonan turns to the latter route, then many of the experiences will not be used by the HTR-10 test reactor.


    "That''s not. Although we have just confirmed that even in liquids or steam, neutron excitation can produce a certain amount of plasma, the concentration is not enough to generate electricity, so the final working fluid still needs helium-xenon to use for helium-xenon Mix the gas, and then add a portion of hydrogen, lithium is just used as neutron shielding..."


    Chang Haonan said as he buckled a hat on his head.


    This is a habit he has developed recently, which can prevent the wind and sand in the air in the northwest from drilling into the gaps between his hair.


    In fact, someone suggested that he shave his hair directly, but in the end he gave up because of Yao Mengna''s strong opposition.


    "hydrogen…"


    Peng Juexian''s eyes lit up when he heard this keyword and immediately thought of the fusion power generation research project he was promoting.


    Hydrogen itself is of course nothing great, but it is well known that there are two other isotopes, deuterium and tritium.


    Among them, the development and utilization of tritium is exactly one of the key points of fusion research at this stage.


    It is also one of the current research shortcomings of China.


    But Chang Haonan walked a little forward and could not see Peng Juexian''s expression, so he naturally thought that the other party was confused about this plan:


    "The conditions in space are no more than those on the ground... Even if nuclear batteries are used, there are considerable restrictions on energy use and equipment life. The density of hydrogen in the gas is the smallest and the load on the circulation equipment is low, which can extend some effective working time. In addition, although hydrogen itself is not easy to ionize, hydrogen with electron clouds can positively promote the ionization process of other gases and is also conducive to the generation of plasma media."


    "As for safety issues, because the protective shell is a positive pressure container, and there is no oxidant in the entire facility, there is no need to worry about it."


    Peng Juexian is still thinking now, and after a few seconds, he nodded after realizing it:


    "I heard from their wind power workers mention this..."


    Speaking of this, the conversation suddenly changed:


    "By the way, Lao Chang, what are your plans in the past few days?"


    This question that was a bit unfinished and unfinished made Chang Haonan pause, but he just thought it was a question on the other party, and then replied after thinking for a moment:


    "It should be nothing before the end of August, so I''m going to go home tomorrow. I haven''t seen my wife and children in more than half a month..."


    During the Olympics, the capital was under martial law, and most flights and trains were temporarily suspended. In principle, only departures are allowed but not entry are allowed.


    However, Chang Haonan''s travel is naturally not affected by these things, and at most it is to back up the matter for relevant departments before traveling.


    Peng Juexian knew that Chang Haonan was relatively free in the second half of August, so he asked this question specifically and prepared to use this excuse to talk about the project situation on his side.


    As a result, I heard that someone wanted to go home to accompany my wife and children, and then I was directly held back.


    As long as he opens his mouth, the other party will definitely not be able to refuse.


    But people can''t, at least they shouldn''t do it.


    Chang Haonan, who was walking in front, heard no reply for a long time, and turned around curiously:


    "Is there anything wrong?"


    Peng Juexian thought that anyway, humans will never have fifty years to go before controlled nuclear fusion, and it is not enough to take more than ten days, so he immediately changed his words:


    "Oh, nothing... bring some local specialties to your younger brother and sister."


    "Well, why are you doing so polite..."


    "It''s all for orders, it''s not worth much..."


    …


    Chang Haonan didn''t tell anyone before returning home.


    Therefore, when he suddenly appeared at the door of his house the next night, Yao Mengna was coaxing Xiao Qihe to sleep in the living room.


    It was not until I heard the sound of the door lock turning that I looked in the direction of the entrance with a little surprise. Immediately afterwards, a light shone in my eyes.


    He looked down at the child who was already asleep in his arms.


    Seeing that the nanny next to him could not understand this posture, he quickly got up and took the child into his hands.


    First, he carried Chang Haonan to him for his look, and then quickly went upstairs without looking back, so fast that even the sound seemed to have some Doppler effect:


    "I''ll take Qihe to the nursery first..."


    Yao Mengna wanted to put on some serious expressions, but the curve of the corners of her mouth couldn''t be suppressed.


    However, after all, he is a decent person, so it is hard to get straight to the topic as soon as he meets him.


    So she tried to find some topics to lay the groundwork:


    "I thought you would be back early next month... I might have to go on a business trip at that time."


    "On business trip?"


    Chang Haonan put Peng Juexian and others in the northwest specialty to him at the door, and raised his head with a surprised expression:


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


    "Where to go?"


    "Go to Rongcheng..."


    Yao Mengna replied that her speaking speed was much faster than usual:


    "The 132 factory encountered a lot of trouble when producing stealth technology verification aircraft. Finally, after evaluation, it was confirmed that only improving the existing equipment was impossible to meet the production requirements of the next generation of aircraft in any case, so they were ready to plan a brand new one The production and assembly workshop needs to be managed in advance to avoid affecting the delivery of subsequent prototypes and mass production machines.”


    Fighters are classified according to key technologies in the overall design field, and there is no strict one-to-one correspondence between them and their manufacturing level.


    Specifically for Huaxia, many models are produced and upgraded, and process parameters are not fixed one after another after the first few or even dozens of batches are delivered.


    It was not until the beginning of this century that the two third-generation fighter jets completed production and finalization relatively quickly.


    However, because the fourth-generation aircraft involves stealth indicators, it clearly stipulates the level of component manufacturing and assembly during design.


    Of course, the technical verification machine is relatively loose in this regard, so old equipment can continue to persist for a while.


    "That…"


    Seeing that Chang Haonan wanted to continue to expand in this direction, Yao Mengna was a little unable to sit still.


    Since it is a prelude, just say a few words.


    If you really talk about work, how can you finish it?


    So quickly interrupt before the other party speaks:


    "No more about this... Are you hungry? Do you want to have some food first?"


    She stood up to tidy up her hair, and then came to Chang Haonan in front of her gently.


    Although he talked about eating, his hands were not like this at all, and he had no intention of moving to the kitchen at all.


    Take the coat from the latter and turn around and hang it on the clothes hanger next to it.


    When I turned back again, I had unbuttoned a button of my pajamas at some point.


    He even pretended to pull the front lapel accidentally, in case the husband in front of him did not notice this detail.


    Fortunately, Chang Haonan is not really a wood, and he is at this point. Of course, he knows what his wife really means.


    If you dare nod and say you go to dinner at this time, you may have to sleep on the sofa tonight.


    "No, I''ve eaten it on the way."


    Chang Haonan said while putting on his nightgown:


    "But I''m going to have some snack after meal..."


    After saying that, Yao Mengna didn''t wait for her to react and exerted force with her arms, hugged the other party''s legs and back, and ran into the bedroom with a "resistance" of punching her chest.


    I wanted to throw the person in my arms directly on the bed and play a role playing of a bully who robs the girl.


    As a result, Yao Mengna changed her posture before entering the door, and wrapped herself around Chang Haonan like an octopus and refused to let go, causing the two of them to fight and get out of the way together.


    Fortunately, the bed in the master bedroom is large enough, so it did not fall to the ground.
