Chapter 288

Li Jiangan looked at Chu Lansheng next to him and said, "Chu, what do you say now?"

Chu Lansheng just said: "General Master Xiao is not even excited, why are you excited?"

Li Jiangan chuckled and said, "You can continue to be tough. Who can be tougher than you? After you are burned, I will go and see if you still have your mouth open."

Chu Lansheng chuckled and said, "It's not certain who will die first, old man."

The two of them were fighting each other, and everyone present was ashamed and didn't dare to interrupt. Who dared to joke like this with the two oldest people in the room.

However, Xiao Yi was indeed not excited. If he were to be excited, he would have been excited when the first simulation was successful.

He did not forget his other goals, so he continued: "Continue to heat, maintain it at 150 million degrees, and hold on for 300 seconds first."

As soon as they heard what he said, the people in Xiwusuo were shocked.

Cao Xu, the current director of the Institute of Western Physics, couldn't help but asked: "150 million degrees? 300 seconds? Is this a joke?"

Taken in isolation, 300 seconds is actually not that long.

At the beginning, EAST had already achieved a record of ultra-long pulse high-temperature plasma power generation of more than 1,000 seconds.

However, when this record was broken, the temperature did not actually reach 150 million degrees, not even 100 million degrees, because it is simply a joke to persist for more than 1,000 seconds when the fusion reaction is above 100 million degrees. The entire EAST will become riddled with holes.

As a result, Xiao Yi actually wants to last for more than 300 seconds at 150 million degrees?

Could it be that he wanted to directly destroy this newly built device?

However, Li Jiangan and Zhao Zhanyou showed no signs of abnormality at all, with normal expressions on their faces.

Seeing this scene, Cao Xu couldn't help but said to Zhao Zhanyou: "Director Zhao, are you sure you don't want to persuade Mr. Xiao? This is no joke! That's 150 million degrees!"

Zhao Zhanyou chuckled and said, "We are not in a hurry, so don't be anxious. Just watch."

Cao Xu suddenly became angry and cursed: "You are completely irresponsible! At such a high temperature, the fusion reaction rate theoretically increases by 3.3 times, and the production of high-energy neutrons will theoretically increase by 3.3 times! Have you ever calculated it? ?”

"Your verification device is so small, how thick can the wall material be? If the internal wall material disintegrates, it will be dangerous!"

"Okay, Cao Xu, don't worry yet."

At this time, Chu Lansheng said something to Cao Xu.

Cao Xu was startled, turned to look at Chu Lansheng, and said, "Mr. Chu, why are you so irrational with them!"

Chu Lansheng still just said calmly: "Listen to me, don't be anxious yet. You see, General Master Xiao is not in a hurry. Do you think your calculation results are better than General Master Xiao?"

"I..." Cao Xu opened his mouth, but finally said nothing and sat aside.

Li Jiangan said with a smile: "Director Cao is quite good, at least he is very responsible. You are a good judge of people."

Chu Lansheng said: "I don't have to worry about it."

"I'm too lazy to worry about it." Li Jiangan said, "However, I do feel that you know something."

Chu Lansheng said with a smile: "Otherwise, why do you think I came to see you? Do you really think I came to see your jokes?"

"If I hadn't made such a big fuss, Liu Cong probably wouldn't have told me about this. He was still worried that I would leak the secret. But now I just know it and don't know why. Now I want to take a look. You are such a low-level material. , how powerful is it..."

Li Jiangan mocked: "No wonder you suddenly stopped making trouble after that, old guy, you're just like a little kid."

Chu Lansheng: "If Xiao Yi hadn't cooperated with you, I'm afraid you would have caused trouble."

Li Jiangan chuckled: "I'm sorry, Xiao Yi is from Feishi, who do you think he wants to cooperate with?"

Chu Lansheng snorted coldly and focused his attention on the big screen again.

At this time, the temperature on the big screen finally exceeded 150 million degrees!

"150 million degrees!"

People in the control room shouted excitedly.

Xiao Yi said calmly: "Starting now, it will be maintained at 150 million degrees for 300 seconds."

Cao Xu's objection just now did not disturb him.

The original plan will not change.

As time passes, 300 seconds, 5 minutes, is not a long time for nuclear fusion. The long time is that mankind has never had a nuclear fusion device that can last for 300 seconds at 150 million degrees. What is not long is that 300 seconds is too short compared to a nuclear fusion device that needs to operate for several years or even ten years without shutting down.

But these 300 seconds will become the dividing line between this long and not long.

As time slowly passed, a timer also appeared on another large screen, counting the 300 seconds.

Various data are also displayed on the large screen next to it, including the key data of impurity concentration.

Impurity concentration refers to various other impurity particles in the reaction chamber except deuterium and tritium fuel.

These impurity particles are generally unavoidable. The main components are residual air particles, impurities produced by laser irradiation during the heating process, and most importantly, the processes such as sputtering and ablation of the first wall and divertor materials, which bring internal coming impurities.

Cao Xu, who sat aside because of sulking, had been staring at the impurity concentration since just now. In his opinion, at a high temperature of 150 million degrees, the impurity concentration would definitely rise rapidly.

However, the UOmini device has been running at 150 million degrees for more than 200 seconds, but the impurity concentration has not changed at all.

From the previous 0.0001%, it is still only 0.0001% now.

"Is it fake? Is the sensor of the impurity concentration broken?"

He pointed at the big screen and couldn't help saying.

This shit hasn't changed. Doesn't it mean that except for the residual air impurities at the beginning and the impurities generated during the laser irradiation heating process, the wall material and the divertor have almost no impurities?

What a joke? !

But no one around paid attention to him.

He walked to the side of Chu Lansheng and told Chu Lansheng the problem.

Chu Lansheng said: "Okay, don't think so much, don't forget what I told you before coming here, ask less and watch more."

"This..."

Cao Xu's eyes widened.

No, in such a strange place, why are you not allowed to ask?

However, at this time, the people present have already focused their attention on the 300-second countdown.

At this time, the 300-second countdown has reached 240 seconds, and there are only 60 seconds left to reach their goal.

Everyone looked at the last 60 seconds countdown with excitement.

And in such a four-minute period, all the data are quite healthy, whether it is fusion power or reaction rate.

But at this time, Xiao Yi suddenly picked up the intercom and said: "Heating group, stop heating now!"

Everyone was stunned. Why stop heating at this time?

Now there are still 60 seconds to complete the 300-second record!

The heating group staff were also quite confused and asked: "Chief Engineer Xiao, stop heating now? Are you sure?"

Xiao Yi just said: "Just do what I say."

"This..."

The heating group staff were even more confused, but they could only do as the chief engineer asked.

Everyone couldn't help but wonder, is Xiao Yi suddenly planning to keep a low profile and not let this result stand out too much?

The heating system stopped.

Just when people thought the temperature was going to drop, they saw that the temperature data on the big screen had not changed at all, and it was still stable at 150 million degrees, and the timer next to it was still heading towards the 300 seconds.

"Lawson criterion!"

Suddenly, the old academician Chu Lansheng said excitedly.

"Fusion has reached the Lawson criterion!"

As soon as Chu Lansheng said this, everyone present reacted immediately and showed shocked expressions.

Lawson criterion!

It means that the fusion reaction can be self-sustaining, and the energy generated by the fusion itself is enough to allow the injected new fuel to enter the fusion state, and no external energy is needed to maintain the reaction!

In the past, no fusion device has ever achieved this result.

Now, they have set a record again!

No wonder Chief Engineer Xiao said that the heating could be stopped. It turned out that he saw that the internal reaction had reached the requirements of the Lawson criterion!

After being shocked for a long time, everyone reacted and then rushed to celebrate.

Applause filled the entire control room.

"You old man, you reacted quite quickly." Li Jiangan said unhappily.

"This only shows that your level is not good enough. You didn't expect it." Chu Lansheng said.

"I just don't dare to think that it has reached the Lawson criterion." Li Jiangan defended himself.

In response, Chu Lansheng just laughed, but didn't mock, because he didn't dare to think about it at the beginning.

In other words, before this, no experts in the world who studied controlled nuclear fusion dared to think that they could reach the Lawson criterion.

Once the Lawson criterion is reached, it almost means that there will be no need to input energy. As long as fuel is added continuously, there will only be output energy, and the efficiency of nuclear fusion power generation will reach the maximum!

This almost means that the dream of nuclear fusion has been half realized!
