Chapter 765 Schemes for Composite Tokamak

The Institute of Materials Science and Engineering is always very efficient. In just two days, the experimental group responsible for the modification of the divertor was set up, with Wang Wei as the group leader in charge of the specific experimental work, while Xu Qingzhou, as before, was responsible for providing support.

"In the simulation experiment, the uniformity of liquid metal coverage deteriorated at 45 MW/m, with exposed areas exceeding 5%."

"Furthermore, the surface temperature fluctuated by ±8℃ at 45MW/m, revealing the deficiency of insufficient heat dissipation in the microchannels. Finally, at a heat load of 50MW/m, the drainage efficiency plummeted to 78%."

Inside the seminar room, Ren Xiaoling explained the local simulation to eight researchers. She was one of the first to participate in the simulation with Xu Qingzhou, and was naturally assigned to Wang Wei's team.

After Ren Xiaoling finished her introduction, Xu Qingzhou shared his ideas: "Structural optimization is needed. My solution involves increasing the density of biomimetic microchannels, which is estimated to improve heat dissipation by 30%. Simultaneously, applying a MgF coating could, optimistically, reduce the evaporation rate by 50%."

Half an hour passed.

"Then we will advance these two plans simultaneously while conducting the experiments," Wang Weichen said.

"Okay, feel free to contact me if you have any questions."

Xu Qingzhou handed over the liquid metal experiment to Wang Wei and went back to his office first.

"Tsk tsk, the heat load can reach 50MW/m divertor. If I hadn't seen the data, I would have really thought it was a joke."

One researcher remarked with emotion.

"Any one of our institute's projects could make controlled nuclear fusion tremble."

"That's true."

"Alright, let's get to work. Although Professor Xu has given us some direction, we're just getting started, and there's a lot to do."

Wang Wei is now considered a mid-level leader in the research institute. He has toned down his behavior a bit and gives people a sense of composure, unlike before when he often argued with Gong Yunfei.

"Hehe, okay, let's get started."

While Wang Wei was busy, Xu Qingzhou had already returned to his office.

The work at the institute is progressing in an orderly manner.

Academician Ren Nan led a team to develop a magnetohydrodynamic diversion technology solution, while Professor Zheng Xu was researching liquid lithium-lead biomimetic microchannel cladding to improve neutron capture rate and thus increase tritium breeding ratio (TBR). Professor Zhao Shengwen was organizing a team to iteratively upgrade the first wall material.

Everyone performs their duties.

"The start date for the next phase of the experiment can be set now."

Xu Qingzhou squinted, holding a teacup as he stood by the window. "At the current pace, the experiment should be able to start around mid-October, around the 12th."

"Two ignition experiments were conducted. The first ignition was to verify the device's net energy gain capability for one minute. The second ignition was to directly verify the duration of the device's net energy gain. The duration was as long as possible."

Of course, it's not about blindly letting the device run until problems arise. Instead, there are data standards. For example, if the quantum sensing magnetic field monitoring system detects density fluctuations or the first wall's condition is not working properly while the device is running, it will stop immediately.

"It's almost September, time flies."

Xu Qingzhou sighed inwardly, "This is probably what the world is like after adulthood. Half a year has passed in the blink of an eye."

He took a sip of tea, then turned and returned to his seat.

On the table is a solution for upgrading the Q1-NTST into a composite tokamak.

Xu Qingzhou is currently upgrading the magnetic confinement system.

One of the major drawbacks of spherical tokamak is the insufficient strength of the circumferential field.

"Our superconducting thin film can raise the magnetic field to over 25T, which means we have solved the key challenge of magnetic field strength. In other words, the only problem we need to solve now is the magnetic confinement efficiency."

“I have studied the construction of a lot of traditional tokamak, and they all rely on external coils to generate a strong helical magnetic field. So, can we build a composite superconducting magnet system based on the current superconducting magnet system?”

To balance compactness and magnetic confinement efficiency, a circumferential field enhancement coil is nested outside the spherical structure, and the toroidal diameter ratio defect is compensated by reverse current.

Xu Qingzhou's initial idea was to construct a nested double magnet layer: the inner layer retains a spherical configuration, while the outer layer is superimposed with D-shaped cross-section circumferential field coils. This retains the advantages of negative triangular plasma and also draws inspiration from the EAST design, axially expanding the vacuum chamber into an elliptical cross-section.

A very bold attempt.

First, design the plan, then hand it over to the staff to simulate it on Qiankun-1 to see if it works.

"The technical solution still needs to be completed by the end of October."

Xu Qingzhou still felt the pressure.

The ignition in mid-October will surely be a resounding success, at which point we can ride the wave of excitement and submit the demonstration reactor construction report to the higher authorities.

August, with its intense heat, has passed, and September is here amidst a flurry of activity.

The tug-of-war between China and the United States remains stalled.

They demanded that we disclose the core data of all our devices, which we naturally refused, emphasizing that we had already shared the device data in accordance with our obligations.

The tug-of-war between the two sides has continued.

Internationally, apart from a few voices of support from those who had previously opposed the freeze on access rights, most remained silent, quietly watching the two countries tug at each other's throats.

There's nothing we can do; we can't afford to offend anyone.

Even France was quiet at this time.

The nail that sticks out gets hammered down. Many French industries rely on China. Although they have suffered a lot of retaliation these days, they are still able to survive. But it would be unwise for them to jump out at this time.

Although China and the United States occasionally clash, they have tacitly limited their conflicts to the field of controlled nuclear fusion.

However, for a moment, it still gave people a feeling that a storm was brewing.

At this point, it's a competition of who can remain calm and, more importantly, who can achieve results that will attract worldwide attention.

The days passed like this.

September 17, Friday, Xishan No. 9 Courtyard.

Outside the window, dusk had already fallen, and the low chirping of insects could be heard.

Xu Qingzhou and Song Yao were on the phone with Lao Xu and the others. In September, Xu Shouyun and Wang Xiaping took their annual leave. This year, they didn't plan to travel around anymore, but instead planned to stay in the countryside for a few days.

Being in the city every day is making me feel like I'm going crazy.

As for traveling, they don't want to do anything. At their age, they've already seen everything they need to see. Last year, they even spent several days traveling in Europe.

After a few days away from home, I'm even more tired than when I was at work.

Goodbye, Aunt Wang.

Song Yao put down her phone and collapsed onto Xu Qingzhou as if all her strength had been drained.

"I'm so tired. I had three meetings today. Let me take a breath of fresh air to recover."

Song Yao was very busy today and didn't get back until after 7 p.m.

Xu Qingzhou asked, "Is the case in Europe over?"

"Yes, we won the case. The other party will compensate us 10 euros."

Song Yao buried her head in Xu Qingzhou's arms, the strong scent of hormones wafting over her, making her feel comfortable.
