Chapter 763 Modification Scheme for Divertors

After taking advantage of Song Yao in the living room, Xu Qingzhou happily ran upstairs.

Outside the window, the rain showed no signs of stopping; in fact, it was getting heavier.

"Work."

Xu Qingzhou pulled out several brand-new manuscripts from the side, quickly got into the zone, and wrote four words on the manuscripts—Liquid Metal.

“Traditional divertors always have drawbacks, so we use other materials to replace the traditional solid tungsten target plate in the divertor.”

This is what suddenly came to his mind while listening to the sound of rain.

"The liquid metal forms a thin film on the target plate surface, and the high heat load is carried away by continuous flow, avoiding local ablation. Moreover, it can automatically fill the damaged area and achieve self-repair function."

"The engineering is quite difficult."

"I had only seen a similar technique before in a paper on materials science for extreme environments, where it was used as a radiation-resistant composite coating."

At this moment, Song Yao also came up in her slippers and walked expressionlessly behind Xu Qingzhou.

"I suspect you want to murder your husband."

"Rub the dog's head in anger!"

Xu Qingzhou: "."

He only returned to his seat satisfied after messing up Xu Qingzhou's hair, then flipped to the half-read legal text next to him and began to read it slowly.

Four days passed in the blink of an eye.

"Whoo~"

"Finally done."

In his office, Xu Qingzhou looked at the laboratory's plans and nodded in satisfaction.

Traditional divertors need to be replaced after a hundred ignitions, but liquid metal solutions, if properly maintained, can theoretically serve indefinitely.

"Of course, to see how effective it is, we still need to conduct local simulation experiments first."

A complete divertor upgrade according to the technical route outlined in the plan requires a team of at least 6 people.

Before assembling the team, Xu Qingzhou planned to first verify the technical feasibility. Once the tests were completed and met the standards, they would then connect to the divertor testing platform of the Qiankun-1 device to conduct verification under neutron irradiation.

"The problem is that everyone at the research institute is busy with their own work and can't spare any manpower to do the simulation."

"In other words, it seems like I'm the one who's the most free."

After considering it, Xu Qingzhou decided to take matters into his own hands. Ren Nan and the others each took charge of a section, and the progress was going smoothly so far, with not much need for his intervention.

However, he still planned to find a helper.

Although there are no fixed projects, it is still necessary to provide support between various projects and help solve some problems. You can't just stay at the experiment all the time.

After thinking about it, he still invited Ren Xiaoling, his senior from his freshman year, to come over and complete the quantum optical frequency comb experiment together.

"Professor Xu, you wanted to see me?"

A short-haired girl quickly appeared at the door.

Six years have passed, and Ren Xiaoling is now a doctoral student. She has lost her former naivety and gained more competence.

"Senior, I'm planning to do a small simulation and I need someone to help me. Are you free?"

Xu Qingzhou said directly.

"Yes, there is." Ren Xiaoling nodded without thinking.

Over the years, she has worked on many projects, but compared to others, she still prefers the feeling of being immersed in knowledge by Xu Qingzhou's side, where she can truly learn a lot.

"Okay, here are the relevant materials. We'll start tomorrow. Take a look at them first, and you can hand over your current tasks to others."

As he spoke, Xu Qingzhou handed over a stack of documents.

Ren Xiaoling is currently working at the research institute as an intern, and doesn't have much work to do. "Oh, okay, I'll go look at the materials now."

Ren Xiaoling was full of energy and left with the documents.

"Wow, time really flies."

"She's no longer the senior student who needed to be taught how to use the equipment step by step."

He had no doubt about Ren Xiaoling's abilities.

As far as he knew, his senior had done a lot of great projects over the years.

Xu Qingzhou sighed and then called Wang Sidong in, asking her to help him book appointments at the materials analysis and testing laboratory and the electrical high voltage laboratory.

Finally, without wasting time, the plan for local simulation testing was improved.

"The key is to test the guiding effect of the scraping layer on the flow of liquid metal, as well as the coverage stability of the liquid metal under heat load."

"For liquid metals, we use bismuth-lithium eutectic alloy (Bi-Li) and liquid tin (Sn)."

The next day, Xu Qingzhou and Ren Xiaoling began their experiments. He personally took charge of the preparation of the first precursor and the entire experimental process, setting an example for Ren Xiaoling. Subsequent experiments were then handed over to Ren Xiaoling.

8 month 24 day.

When Academician Ren Nan arrived at Xu Qingzhou's office and sat down opposite him, he asked, "I heard you're testing liquid metal?"

"Yes, we want to see if this thing is useful in a divertor."

“I think Princeton has done some research on this, but it’s all still conceptual, and there don’t seem to be any actual cases yet.”

"Yes, it's quite difficult, so I plan to conduct a simulation first to see if it's feasible."

As he spoke, Xu Qingzhou prepared to pour tea.

"I won't drink the tea. This is our magnetohydrodynamic diversion technology solution. Take a look."

Professor Ren Nan handed over the USB drive.

"The joint team conducted two more rounds of experiments, and as you predicted, the energy consumption of the magnetic confinement neutron focusing system has reached 16% of the total device."

Ren Nan continued, "Furthermore, the focused neutron beam increases the energy flux by 80% in the local region of the breeding layer, which can easily cause local melting and damage to the cladding material."

"Professor Zheng and I discussed it and decided to abandon the magnetic confinement neutron focusing system for now."

"I have no opinion."

Xu Qingzhou said.

The magnetic confinement neutron focusing system is a complex engineering project, requiring the addition of a superconducting magnetic lens array outside the vacuum chamber, whose magnetic field distribution must be precisely matched with the outward magnetic field of the negative triangular configuration.

"Okay, take a look at the plan first, and we'll revise it if there are any problems."

Ren Nan sighed, this might be the benefit of having a top mathematician support the experiment, top-notch prediction, saving a lot of trouble.

He didn't waste any time there and got up to leave.

Xu Qingzhou slowly flipped through the proposal.

An hour passed quietly.

He signed the proposal and asked Wang Sidong to deliver it to Ren Nan.

Old ginger is spicier; Academician Ren truly deserves to be called one of the first generation of researchers in China working on controlled nuclear fusion.

The plan he personally oversaw was very detailed, encompassing the neutron flux distribution optimization design and enhanced thermal management mentioned by Xu Qingzhou. It even added many highlights, such as adding a reverse eddy current coil in the vacuum chamber to actively guide the particle flow away from weak areas, as well as some heat dissipation technologies.

“In addition to affecting the tritium breeding ratio (TBR), the magnetohydrodynamic (MHD) diversion technology seems to be able to work in synergy with the liquid metal we are working on to further improve the performance of the divertor.”

Xu Qingzhou squinted, feeling that there was great potential.

"The premise is that the liquid metal solution is viable."
