"On land, the recovery of tritium from the plasma exhaust gas and the supply of tritium and deuterium have been studied in the Tokmak plant before.

Now they have improved the technology based on the parameters of the stellarator we have provided, and can be tested on the stellarator. ”

Two months later, Zhang Qing and Lin Meng have become Lu Yi's assistants, and under Lu Yi's arrangement, they have made research breakthroughs on one topic after another.

It's not that their research ability is not good, on the contrary, it is precisely because the potential of scientists is too high, and more talents are focused on research, and they can't handle such a large project too well.

"Zhang Qing organized personnel to start the stellar simulator for ......"

Lu Yi grabbed a handful of hair that had grown a little long, took his attention back from a general progress report of the project, and said: "Forget it, increase the plasma temperature to 9.8 million degrees Celsius, and then introduce deuterium-tritium and helium for actual simulation tests to verify deuterium-tritium recovery and resupply." ”

I just wanted to say that Zhang Qing should actually conduct an ignition fusion experiment to collect data, but I remembered that the material of the inner wall of the stellarator has not been replaced, and the first inner wall is almost semi-scrapped after an ignition fusion test, so I changed this idea again.

The temperature is 9.8 million degrees Celsius, and the deuterium and tritium will not be fused, and there will be no neutron irradiation to cause serious damage to the first inner wall that has not been replaced, so the material can be saved.

In two months, the material consumption generated by countless experiments to collect data, 80 billion yuan has been spent, and nearly 30 billion yuan has been spent.

This terrifying speed of spending money made Xu Ying look full of admiration when she brought the financial statements every week, and the two assistant managers arranged above were heartache.

Of course, the money is well spent, and it can be said that it is unknown so far, but the technology of most of the components of the nuclear fusion demonstration reactor is up to standard, and the final plan can be determined and the construction of the core area can be started after the last few tests are completed.

"How's the progress going on at Max Planck's lab?" Lu Yi turned his pen, wrote down today's itinerary, and then asked Zhang Qing.

"They changed the plan, it seems that the test of the material did not find the defects at the first time, and it was not until half a month ago that the structural improvement was carried out to determine the final plan, and then the construction of the core area was restarted."

"Big money." Lu Yi smiled, he originally estimated that he could earn it after a month, but he didn't think about it but extended the time to a month and a half.

It seems that only the three of them know the specific progress, and the decision of not telling the other researchers is correct, and the Max Planck lab does not know the specific progress of its own side, and the plan to save $400 million a year is very tempting, so the plan will be improved.

"Let's go, today we are going to the EAST project, where we are conducting high-energy neutron irradiation experiments on the first inner wall material."

Lu Yi, who was in a good mood, stood up, closed his laptop and beckoned Zhang Qing to go out.

The first inner wall material needs to be exposed to high-energy neutrons with an energy of 14 MeV, and the irradiation intensity of this neutron is far more than ten times that of any fission reactor, and the environment created by the laboratory or nuclear power plants such as Daya Bay cannot meet this test condition.

The only ones in China that can meet the conditions are the Tokmak devices that can carry out ignition fusion experiments in the EAST project and the Tomorrow Star Simulator on Lu Yi's side.

There is only one stellarator, which will still be the core of the demonstration reactor in the future, and it is too precious to be applied to the collection of this kind of experimental data, so this can only be found in the domestic tokmak.

"Lu Lu, the newly improved deflector has greatly improved the discharge of impurities such as helium nuclei produced by fusion, and the prevention of impurities from inner wall materials from entering the plasma, which can meet the needs of the demonstration reactor, but it is still a bit bad for the problem of uneven heat."

At this time, Lin Meng walked over with a copy of the latest test data, looking a little anxious.

The data in her hand is the performance parameters of the latest deflector, which are matched to the plasma energy density and the rate of deuterium-tritium fusion when the demonstration reactor is actually generated.

The passage of the data level is the premise of practical application, and now the latest domestic deflector at the data level cannot meet the standard, so the practical application will definitely not pass.

After two months of intensive work by countless researchers in many laboratories across the country, the problems left in front of the stellar simulator demonstration reactor are the first inner wall material, deflector, and superconducting graphene wire.

The third one can be pushed back, but the first two can't be completed, and the fusion demonstration reactor is the moon in the dream.

"How much better is the temperature control room than before?" Lu Yi was not in a hurry, but asked about the performance parameters of the latest deflector.

As the chief engineer of the project, there are many technological breakthroughs in the project, except for the laboratory and he knows, even Zhang Qing and Lin Meng do not necessarily know.

In addition to removing exhaust gases and impurities from the plasma and maintaining the purity of the plasma, the deflector also has an important function of temperature control.

Because the plasma orbit is twisted and irregular, some areas will produce plasma aggregation phenomenon that causes temperature accumulation, and one of the main functions of the deflector is to eliminate these plasma aggregation and balance the temperature to ensure the stable operation of the reactor.

If this function cannot be met by the deflector, it can be compensated in other aspects, such as the improvement of the high temperature resistance and plasma radiation resistance of the first inner wall material, such as the further improvement of the magnetic field of magnetic confinement, so that even the plasma accumulation can be rigidly restrained.

"This is an increase of 38.9 percent from before, and theoretically it needs to reach 47.6 percent to meet the requirements of the demonstration reactor."

Seeing that Lu Yi's face was not in a hurry and panicked, Lin Meng, who was originally a little anxious, also calmed down and said the parameters of the latest deflector.

"38.9 percent is enough, the material composition of the first inner wall has been improved after many improvements, and the magnetic field strength can also be greatly improved after the outer magnetic field coil is replaced with superconducting graphene wire."

Lu Yi roughly calculated in his mind and said, "Remember to ask Hu Feng later, if their building blocks are finished, how is my superconducting graphene wire mold." ”

"Okay."

Zhang Qing nodded, Xu Ying was coordinating the matter of building blocks in the laboratory, and now this matter was handed over to her for the time being, and Lin Meng was in charge of all the data level things.

Lu Yi looked at Zhang Qing and Lin Meng, whose faces were a little dull and their hair was boring, and said, "After finishing these few problems, we will be relaxed in the future." ”

"You said this when you were working on plasma turbulence models."

Zhang Qing and Lin Meng rolled their eyes, then turned around and walked forward hand in hand, leaving Lu Yi behind.

"Don't go so fast."

Lu Yi shouted behind him: "Go back and bring a U-shaped pillow, Yangcheng has been going to the science and technology island for a long time, just so you can take a rest on the plane, don't forget the toiletries, you should stay there for a few days this time." ”

During this time, not only were the tens of thousands of scientific research dogs working overtime, but Lu Yi and the others were almost idle every day, and they were even more busy until the early hours of the morning yesterday for a few hours.
