Chapter 422 Final Preparations!

Accompanied by the instructions from the top, the instruction document passed all the reviews at the fastest speed and was sent to the Qixia Controlled Nuclear Fusion Engineering Base.

At the same time, the security near the Qixia Controlled Nuclear Fusion Engineering Base directly entered the highest level of alert.

Xu Chuan took the instruction document from Gao Hongming, flipped through it and put it on the desk.

For him, this kind of instruction document is no longer a rare thing.

"By the way, Academician Xu, have you decided on the time for the demonstration reactor to be ignited?"

After sending the instruction 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, "These are all fine, but can you please let me or Captain Zhou, who is in charge of security, know a few days in advance when you confirm the date."

"After all, the ignition of the demonstration reactor is a big deal. We need to notify the Jinling Municipal Government to cooperate in handling transportation, safety, publicity and other aspects."

Hearing this, Xu Chuan nodded and said, "This is no problem. When the work on the demonstration reactor is completed, I will notify you if I can confirm the time."

Gao Hongming nodded and said, "Thank you for troubling Academician Xu."

"It's nothing."

After a casual polite remark, Xu Chuan picked up the pen and was about to continue his work. He saw Gao Hongming still standing in his office from the corner of his eye.

Looking up, he looked over curiously and asked, "Anything else? Hall Gao?"

Gao Hongming took a deep breath and asked tentatively, "Well, Academician Xu, given your busy work and unstable life and schedule, Shou Zhang told me that he wants to arrange a life and medical assistant for you to ensure your health. What do you think?"

It's not just him who has a headache about arranging a life assistant for Xu Chuan, the higher-ups are also having a headache.

According to common sense, academicians and researchers at this level are basically arranged with life assistants, or they are relatively old, have started a family, and have family members or nannies to take care of their daily lives.

But the person in front of him is an exception.

When he was elected as an academician, he was only 22 years old.

At this age, for other people, it is probably just college graduation.

It is not only difficult to find a suitable candidate for him to arrange a life assistant. And more importantly, this person seems to be very resistant to this matter.

When he was in charge of the "Nuclear Energy β Radiation Energy Concentration and Conversion Electric Energy Mechanism Technology Project", the higher-ups proposed to arrange a life assistant for him, but he refused several times.

Maybe young people are not used to this?

In short, it was useless for them to beg for help. Not to mention a life assistant, he didn't disagree to arrange a nanny for him to cook and clean the villa at the foot of Zijin Mountain.

So many times, this famous academician still relies on takeout for meals.

To be honest, this kind of thing may not be believed if it is told out.

But the higher-ups are also suffering. It's not that they don't want to match it, but this person really doesn't want it.

So this time, when Gao Hongming mentioned this matter, he was still nervous, afraid that this person would refuse it 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 didn't even think about it and directly refused it again.

"Forget it, it's not like I can't take care of myself. I'd better not have a life assistant. There's no need."

For him, life assistant has always been a distant word. He only learned about it when watching TV a long time ago.

And, to be honest, he really doesn't like an outsider living in his house.

Not to mention a strange life assistant, even Zheng Hai, who has been his driver for two or three years, has never lived in his house.

Hearing Xu Chuan's answer, Gao Hongming smiled bitterly and shook his head.

The task assigned to him by the superiors failed again.

But fortunately, the superiors also knew the character of this person. This time it was not mandatory. It was just a tentative inquiry. What if this person changed his opinion?

Xu Chuan didn't care about this matter. After receiving the approval document for the ignition of the demonstration reactor, he turned around and got into work.

After the fully optimized liquid lithium molten salt tritium breeding system was confirmed to be fine by supercomputer simulation verification, it was actually tested on the Dawn Experimental Reactor.

The experimental data was delivered to Xu Chuan by Zhao Hongzhi at the first time.

"Academician Xu, the test data of the liquid lithium molten salt tritium breeding system is out."

"We used a 567mg Nb activated foil for monitoring. The Nb activated foil was placed at 30° to the right of the neutron emission direction and 22.6 cm away from the target."

"The D beam energy is 250 keV. After D-T reaction anisotropy correction and rotating target attenuation correction calculation, the activation reaction rate R of the Nb activated foil at this point is 6.26×10-29. Combined with the irradiation and measurement conditions, the total integrated yield of the neutron source is calculated to be 4.68×1015 neutrons."

Listening to Zhao Hongzhi's report, Xu Chuan directly turned the report results to the final TBR numerical statistical table.

TBR value refers to the tritium multiplication ratio, which is an important indicator to measure the self-sustaining ability of the blanket tritium and one of the key design parameters of the fusion reactor design.

Considering the decay, retention, leakage, circulation extraction efficiency, fuel consumption and other effects of tritium, the TBR of the fusion reactor blanket must be greater than 1.1 to perfectly achieve tritium self-sustaining and maintain the operation of the fusion reactor.

[Fusion reactor blanket TBR numerical statistics: MCNP: 1.2701]

[Fusion reactor blanket TBR numerical statistics: MCNP: 1.2897]

Seeing these two data, Xu Chuan showed a bright smile on his face.

"Using the same CFETR neutronics model and FENDL3.1b database, the TBR values ​​calculated by the two software under the same sampling conditions differ by less than 0.1%."

"Excellent data. Theoretically, this is enough to meet the operation requirements of the fusion reactor."

On the other side, Zhao Hongzhi also said excitedly: "We have mastered all the core puzzles. Now we are waiting to assemble them!"

Xu Chuan smiled and nodded, saying: "Theoretically, this is the case, but in order to ensure the success of the demonstration reactor ignition, we need to do better."

"So before October 1st, the Dawn Research Institute has a heavy task."

"We must repeat the inspection of every problem that has been solved and every technology to ensure that there is no mistake!"

Zhao Hongzhi replied with a surge of emotion: "No problem! Guarantee to complete the task!"
