Before returning to the college entrance examination, I became popular in the science circle

As the plasma control system has also been declared a breakthrough, the Golden Crow Project as a whole has faced many hurdles, and the core difficulty has been overcome. It is also coming to an end, and the progress is gratifying.

The progress of each item was reported to Wu Tong. Some reserves of superconducting materials have been prepared. The first wall material, the site has been selected, the equipment is in place, adjustments have been completed, and production has officially started. The water-cooled divertor itself is something Wu Tong is ready to get started with. section.

However, at the first collective discussion meeting, Academician Wan had good research results in this field. This part of the separate research and development was handed over to Academician Wan to lead a team to overcome.

After Academician He returned from the southwest, he took over the supervision and follow-up work of Academician Wan, allowing Academician Wan to free up his energy and personally lead the team to conduct in-depth research and development in this section. At present, the same good news has come, and there has been a breakthrough in preliminary progress in research and development. It is expected that To install a divertor inside the reactor, the initial schematic drawings have been released and sent to Wu Tong!

"Mr. Wu, this is based on the Thomasko water-cooling device, which we have modified and constructed with new ideas! EAST, by gradually increasing the H&CD power, the divertor heat load can exceed 10 MWm-2 under steady-state conditions. ITER-type long-pulse H-mode plasma.

Therefore, a graphite PFC with a heat removal capacity of 2 MWm-2 cannot meet the physical requirements.

In addition, ITER's PFC was converted from carbon/beryllium (C/Be) to an all-metal wall with a tungsten (W) divertor target plate. In order to study the performance of all-metal wall plasma, we used an all-tungsten divertor at EAST, with a heat flow processing capacity of up to 10 MWm-2. In theory and simulation experiments, the data performance is still good, and there is this in-depth To tap the potential, we are studying it carefully! "

Academician Wan opened his mouth to report a complex combination of data and parameters. When talking to Mr. Wu, instead of talking to the superiors, he had no restrictions. He only reported the core content. Mr. Wu was the core and soul of their project. These were very important to Mr. Wu. It’s all basic knowledge, so there’s no need to worry that Mr. Wu won’t understand!

"In order to provide valuable experience before ITER operation, similar materials, structures and technologies were used for EAST. ITER-grade tungsten was used in the PFC, but due to the mismatch in thermal expansion coefficient and Young's modulus, The combination of tungsten and CuCrZr is difficult.

After several experiments, we finally found that the preparation of tungsten modular PFC is divided into two steps: first, use hot isostatic pressing (HIP) method to coat the tungsten monomer module and connect it with the pure copper interlayer; then, use hot radial pressing Welding (HRP) method is used to weld the tungsten monomer module to the CuCrZr tube. Brazing and electron beam welding are used to seal and weld pure copper tubes and tungsten single modules in a vacuum environment, and then HIP processing is performed..."

Academician Wan talked and gestured to Wu Tong about their journey in the water-cooled divertor. Hey, ITER is very expensive, and his old friend Dongfang Huan was the test product. To be honest, he was very excited before. Not angry, but suppressing anger. But there is nothing he can do. The current situation does not allow him to be willful!

But, hehe... It's different now. They have Mr. Wu, and their stellarator device has seen the dawn of light. All the obstacles that have blocked the progress of the world have been transformed into Mr. Wu's hands. The real breakthrough results laid the foundation for their solid and stable steps in the field of controllable nuclear fusion!

Just thinking about it makes Academician Wan feel happy and excited! Under such a state, his research and development seemed to be going more smoothly. It was beyond his expectation that he had made initial progress so quickly, and it also made him happy and cheerful!

"The bonding quality of tungsten and copper is good, and the bonding strength is greater than 150 MPa. The ultrasonic non-destructive testing (NDL) results show that the combination of tungsten block and copper block meets the technical requirements, and the fatigue resistance test and overheating endurance test all performed very well potential!"

Hey, this kind of technology, this time they are going to give it to their Golden Crow to use first. Internationally, just let it go as you please! Now that they have the Golden Crow, they won’t be greedy for the poor and exquisite technology in the world! So what if we burn bridges across rivers? Don't they regard them as being taken advantage of and just be greedy and ask for endless funds!

"Combining tungsten with copper? This is an interesting idea, Academician Wan, please allow me two days to deduce it!" Wu Tong listened carefully to the parameter data reported by Academician Wan, and in his hand was the research materials led by Academician Wan. What is condensed can be said to be the condensed essence of the entire controllable nuclear fusion in China over the past [-] to [-] years.

That is to say, with a core leader like Academician Wan leading the team, they can so perfectly undertake this technology and transfer it to further research and development of the stellarator device. These core information, even with her authority, could not be understood as clearly and thoroughly as academician Wan, who is a master of database experience.

With Academician Wan's detailed summary of ideas and experience, she was confident that she could come up with an optimization plan in a short time. Fortunately, she now has some time to focus on.

"I've been waiting for Mr. Wu's words, so I'll wait for the good news from Mr. Wu!" Academician Wan smiled with satisfaction and left the information to Wu Tong. Ever since he learned about Wu Tong's unique talent in optimization, he had been thinking about this good thing. Their research and development in this field has reached a current ceiling, and there is no better way to break through it for the time being.

Asking Mr. Wu to give them some new research and development angles was an idea he had after learning that Wu Tong's research and development of the WS-15S aero engine started with optimization. Therefore, when Academician He came back from the southwest, he handed over the stall in his hands to Lao He, and led the team to devote all their efforts to research and development, and transferred the divertor device on the Dongfang Ring, which was relatively complete, to the specifications that can be used by the Jinwu Project. parameter.

"Thanks to Academician Wan, I'll try my best!" Wu Tong laughed. She was not an all-powerful jingle cat, she had an all-purpose pocket. Before the results are completely revealed, Wu Tong cannot be sure, "Everything still depends on the results!"

The final result is the most reliable. Whether it can be used and whether it is successful or not is clear at a glance!

Of course, Wu Tong still has a lot of confidence in optimizing this plan. Otherwise, he would not have given a specific waiting time. This is already a rare promise made by Wu Tong in words.

"Haha... I absolutely believe in Mr. Wu!" Academician Wan shouted and left with a smile and hope.

After sending Academician Wan out, Wu Tong returned to the office to write. He pulled out the draft paper, and a series of derivation formulas bloomed like flowers on the draft paper, transforming Wu Tong's brainstorming into mathematics, materials, and engineering language. Expressed in this line-by-line deduction, a new breakthrough is just around the corner!
