Following the instructions from the top management, the approval documents passed all reviews as quickly as possible and were sent to the Qixia Controlled Nuclear Fusion Engineering Base.
At the same time, the security near the Qixia Controlled Nuclear Fusion Engineering Base has directly entered the highest level of alert.
Xu Chuan took the instruction document from Gao Hongming, flipped through it and put it on his desk.
For him, this kind of instruction document is no longer a strange thing.
"By the way, Academician Xu, have you determined the time for ignition of the demonstration reactor?"
After sending the approval document, Gao Hongming asked in the office.
Hearing this question, Xu Chuan thought for a while and said: "It has not been determined yet. It depends on the overall progress of the demonstration reactor project."
"But the forecast should be around October."
Gao Hongming nodded and said: "There is nothing wrong with these, but could you please tell me or Captain Zhou who is in charge of security a few days in advance when confirming the date?"
"After all, the ignition of the demonstration reactor is a major event. We need to notify the Jinling Municipal Government to cooperate in handling traffic, safety, publicity and other aspects of the work."
Hearing this, Xu Chuan nodded and said: "This is no problem. When the work on the demonstration pile is completed, I will notify you if I can confirm the time."
Gao Hongming nodded and said, "I'm sorry to trouble you, Academician Xu."
"this is nothing."
After saying a casual courtesy, Xu Chuan picked up the signature pen and was about to continue working on his work. Out of the corner of his eye, he saw Gao Hongming still standing in his office.
Raising his head, he looked over curiously and asked, "Is there anything else? Gao Hall?"
Gao Hongming took a deep breath and asked tentatively: "Well, Academician Xu, in view of your busy work and unstable living conditions and routine, Zhang Zhang told me that he would like to arrange a life-long medical care for you.
Assistant, what do you think about protecting your health?"
Regarding the matter of arranging a life assistant for Xu Chuan, it was not only him who had a headache, but also those above him.
According to common sense, scholars and researchers at the level of academicians are basically arranged with life assistants, or they are relatively old and have married and have family members or nannies to take care of their daily life.
But the person in front of me is an exception.
He was only twenty-two years old when he was elected as an academician.
At this age, for other people, they may have just graduated from college.
Not only is it difficult to find a suitable person to arrange a life assistant for him, but more importantly, this person seems to be very resistant to it.
When he was leading the "Nuclear Energy Beta Radiation Energy Concentration and Conversion Electric Energy Mechanism Technology Project", the superiors proposed to arrange a life assistant for him, but he rejected the proposal several times.
Maybe young people are not used to this?
In short, it was useless for them to beg his grandfather and grandma. Let alone a life assistant, even if they arranged a nanny for him, cooked for him in the villa at the foot of Purple Mountain, and did some cleaning, he would not disagree.
So much so that this famous academician still relies on takeout for meals.
To be honest, no one may believe this kind of thing.
But it’s hard up there too. It’s not that they don’t give me money, it’s that this person really doesn’t want it.
So this time, when Gao Hongming mentioned this matter, he was still worried, fearing that this person would reject him again.
But as the saying goes, the more you worry about something, the more likely it is to happen.
Sure enough, after hearing this request, Xu Chuan refused without even thinking.
"Forget it, it's not like I can't take care of myself. I'd better skip the life assistant thing. It's not necessary."
For him, life assistant has always been a very distant term, and he only learned about it when watching TV a long time ago.
Moreover, to be honest, he really doesn't like an outsider living in his home.
Not to mention a strange life assistant, even Zheng Hai, who had been his driver for two or three years, had never lived in his house.
Hearing Xu Chuan's answer, Gao Hongming smiled bitterly and shook his head.
The task assigned to him by his superiors failed again.
But fortunately, the person above is also aware of this person's character. This time it is not mandatory. It is just a tentative inquiry. What if this person changes his opinion?
.......
Xu Chuan didn't pay attention to this matter. After receiving the instruction document for igniting the demonstration pile, he turned around and got into work.
After being fully optimized, the liquid lithium molten salt breeding tritium system was confirmed to have no problems through supercomputer simulations, and then the actual test was carried out on the Daybreak Experimental Reactor.
The experimental data was sent to Xu Chuan by Zhao Hongzhi as soon as possible.
"Academician Xu, the test data of the liquid lithium molten salt breeding tritium system has come out."
"We used an Nb activation foil with a neutron source mass of 567 mg for monitoring. The Nb activation foil was placed at 30° to the right of the neutron emission direction, and the distance from the target was 22.6 cm."
"The D beam energy is 250 keV. After D-T reaction anisotropy correction and rotating target attenuation correction calculation, the Nb activation foil activation reaction rate R at this point is 6.26x10-29. Combined with the irradiation and measurement conditions, the total neutron source is calculated
The integral yield is 4.68x1015 neutrons...."
After listening to Zhao Hongzhi's report, Xu Chuan directly turned over the report results to the final TBR numerical statistics table.
The TBR value refers to the tritium reproduction ratio, which is an important indicator to measure the self-sustaining ability of tritium in the cladding and is also one of the key design parameters in fusion reactor design.
Taking into account tritium's decay, retention, leakage, cycle extraction efficiency, burn-up and other effects, the TBR of the fusion reactor cladding must be greater than 1.1 in order to achieve perfect tritium self-sustainability and maintain the operation of the fusion reactor.
Seeing these two pieces of data, Xu Chuan had a bright smile on his face.
"Using the same CFETR neutronics model and FENDL3.1b database, the difference in TBR values calculated by the two software under the same sampling conditions is less than 0.1%."
"Excellent data. Theoretically, this is completely sufficient to meet the operation requirements of the fusion reactor."
On the opposite side, Zhao Hongzhi also said excitedly: "We have mastered all the core puzzle pieces, and what we are waiting for now is to assemble them!"
Xu Chuan smiled and nodded, saying: "Theoretically, this is true, but in order to ensure the success of the demonstration reactor ignition work, we need to do better."
"So before October 1st, Dawn Research Institute has a very heavy task."
"We need to repeatedly check every problem that has been solved and every technology to make sure nothing goes wrong!"
Zhao Hongzhi replied with excitement: "No problem! I promise to complete the task!"
