With the instructions of the high-level, the approval documents passed all the reviews as soon as possible and were sent to the Qixia controllable nuclear fusion engineering base.

At the same time, the security near the Qixia controllable nuclear fusion engineering base directly entered the highest level of alert.

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

For him, such instructions are no longer a novelty.

"By the way, Academician Xu, have you determined the time for the ignition of the demonstration pile?"

After sending the approval documents, Gao Hongming asked in the office.

Hearing this question, Xu Chuan thought for a while and said, "It has not been determined for the time being, 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 can you please say hello to me or the head of the security department Zhou a few days in advance when you determine the date." ”

"After all, the ignition of the demonstration pile is a major event, and we need to notify the Jinling Municipal FU to cooperate with the traffic, safety, publicity and other aspects of the work."

Hearing this, Xu Chuan nodded and said, "There is no problem with this, when the work on the demonstration pile is completed, I will notify you if I can determine the time." ”

Gao Hongming nodded and said, "Trouble Academician Xu." ”

"It's nothing."

After casually saying a polite sentence, Xu Chuan picked up the pen and was about to continue to deal with his work, when he saw Gao Hongming still standing in his office out of the corner of his eye.

Raising his head, he looked over curiously and asked, "Is there anything else?" High Hall? ”

Gao Hongming took a deep breath and asked tentatively: "That, Academician Xu, in view of your busy work and not very stable living conditions and schedules, Shouzhang explained to me that I want to arrange a living medical assistant for you to ensure your health, what do you think?" ”

For the matter of arranging a living assistant for Xu Chuan, he is not the only one who has a headache, but also a big headache.

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

But the one in front of me is an exception.

He was only twenty-two years old when he was elected a fellow.

At this age, for others, they have probably just graduated from college.

Arrange him with a life assistant, not only is it difficult to find the right person. And more importantly, this one seems to be very resistant to this.

When he was in charge of the "Nuclear Energy β Radiation Energy Aggregation and Conversion Mechanism Technology Project", he proposed to arrange a living assistant for him, but he rejected several times.

Presumably young people are not used to this?

In short, it was useless for them to beg grandpa to tell grandma, let alone a life assistant, that is, to arrange a nanny for him, cook for him in the villa at the foot of the Purple Mountain, and clean up for him, he didn't disagree.

So much so that many times this famous academician still relies on takeout for dinner.

To be honest, this kind of thing may not be believed by anyone when it is said.

But it's also bitter above, it's not that they don't match, it's that this one really doesn't want it.

So much so that this time, when Gao Hongming mentioned this matter, he was still nervous, afraid that he would refuse again.

But as the saying goes, the more you worry about something, the more likely it is that something will happen.

Sure enough, after hearing this request, Xu Chuan didn't even think about it, and refused it directly.

"Forget it, it's not that I can't take care of myself, life assistants, it's better to be exempt, there's no need."

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

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

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

Hearing Xu Chuan's answer, Gao Hongming shook his head with a wry smile.

The task assigned to him from above failed again.

But fortunately, the first Zhang above also knows the character of this person, and this time it's not mandatory, just ask with a tentative question, what if this one changes his opinion?

Xu Chuan didn't care about this either, and after receiving the instructions for the ignition of the demonstration pile, he turned around and put himself into work.

After the fully optimized liquid lithium molten salt multiplication tritin system, the actual test was carried out on the Daybreak experimental reactor after the supercomputer simulation verification confirmed that there was no problem.

The experimental data was sent to Xu Chuan by Zhao Hongzhi in 1 as soon as possible.

"Academician Xu, the test data of the liquid lithium molten salt proliferation tritin system has come out."

"We used a neutron source strength mass of 567 mg of Nb-activated foil for monitoring, and the Nb-activated foil was placed 30° to the right of the neutron exit direction and 22.6 cm away from the target."

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

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

TBR, or tritium breed ratio, is an important indicator to measure the self-sustaining ability of cladding tritium, and is also one of the key design parameters for fusion reactor design.

Considering the effects of tritium decay, retention, leakage, cyclic extraction efficiency, and burn-up, it is required that the TBR of the fusion reactor cladding must be greater than 1.1 in order to perfectly achieve tritium self-sustaining and maintain the operation of the fusion reactor.

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

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

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

"Using the same CFETR neutronomics model and the FENDL3.1b database, the difference in TBR values calculated by the two software under the same sampling conditions is less than 0.1%."

"Very good data, theoretically enough, to meet the operational requirements of a fusion reactor."

On the other 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 nodded with a smile and said, "Theoretically, this is the case, but in order to ensure the success of the ignition work of the demonstration pile, we need to do better." ”

"So before October 1st, the task on the side of the Daybreak Research Institute is very heavy."

"We have to repeat every problem that has been solved, every technology, to make sure that nothing goes wrong!"

Zhao Hongzhi replied excitedly: "No problem! Mission completion guaranteed! ”
