Chapter 377 375, Raw Materials for Controllable Nuclear Fusion

The two children were sent away to college, and the house suddenly became empty.

My daughter is fine. She has video calls and phone calls with her family within a day or two.

As for the son? Su Yu always had the illusion that she had never had an eldest son.

This kid called his mother right after the freshmen military academy ended, and then lost contact with her completely.

Su Yu stopped thinking about it. She would be angry to death if she thought too much. She took her briefcase and walked out of the house and walked into the office of Qingjiao University.

"teacher."

Seeing his godfather Su Yu come in, Zhang Xiwen, who had finished mopping the floor, immediately handed him some tea.

"Well, thank you!"

Su Yu smiled and nodded. Public opinion in the outside world used to be saying how arrogant and domineering this young master was, but Su Yu thought he was very good.

Su Yu has been staying in the office for half a year, and Zhang Xiwen has also been staying here with Su Yu for half a year.

Su Yu didn't see his arrogance or domineering at all. Instead, she liked the young man's positivity and motivation.

And spending half a year in the office also meant that Su Yu finally gained something.

I don’t know if I am really getting older, or if the topics I have been exposed to recently have become more and more difficult. Now it takes a long time for Su Yu to write a paper.

When Su Yu was young, she wanted to write a thesis, but it was really easy!

But now, on the one hand, he is a pioneer at the forefront of the academic field, and every paper he writes will affect the direction of the world, so Su Yu is "in awe" of every paper he writes from the bottom of his heart;

On the other hand, it may be that she is really old. Su Yu is forty-eight this year and will be fifty soon.

After taking a sip of tea, Su Yu spread a piece of white manuscript paper on the table, thought about it, and started writing a new paper.

The reaction cross section of deuterium-tritium fusion is more than two orders of magnitude higher than other fusion reactions. 2 grams of deuterium and 3 grams of tritium can produce about 1.68 trillion joules of energy.

Converted into electricity units, it is 467,000 kWh, which is approximately equivalent to the energy produced by the combustion of 73 tons of 5,500 kcal coal or the fission of 20 grams of uranium 235.

However, this is only theoretical data. Whether it is the "Qingjiao No. 1" reactor that has been operating continuously for more than a year, or other newly built Huaxia controllable nuclear fusion reactors, they are limited by the limitations of supporting equipment and technology, and the pressure and pressure inside the reactor. The temperature has not reached the optimal state, and the energy conversion efficiency is not optimal either.

Thermal efficiency conversion in the large-scale controllable nuclear fusion route represented by "Qingjiaotang No. 1" means that the miniaturization route that Su Yu has always wanted to take is even more restricted.

So Su Yu has been solving this problem in the past six months, and his solution is to start with raw materials.

On the white manuscript paper, Su Yu drew a coordinate axis based on various data, and then began to slowly explain the relevant parameters on the coordinate axis:

"To determine the fusion triple product of ignition, according to the traditional Lawson criterion, when the three parameters of plasma temperature, plasma density and confinement time reach certain conditions, the energy yield rate of the nuclear fusion reaction will be greater than the energy loss rate. And there is enough energy to make the nuclear fusion reaction stable and continuous.”

China's controllable nuclear fusion has achieved vigorous development, which also means that China's controllable nuclear fusion raw material extraction industry has developed rapidly.

There is currently only one large-scale supplier of controllable nuclear fusion raw materials in the world - Huaxia Nuclear Energy Materials Group located in Jiaodong City. The group has operated 20 reactors, each of which can produce 2kg of tritium per year. , the domestic trade price is 200,000 yuan/g, and the foreign trade price can reach 1 million yuan/g.

At present, the "Qingjiaotang No. 1" fusion reactor consumes about 1kg of tritium for every 100 million kWh of electricity produced. Generally speaking, this energy is still very cheap.

But what Su Yu wants is not cheapness, but miniaturization, because only miniaturization can lead to broad application prospects.

Time is ticking by, and Su Yu, who is sitting in her seat, is constantly outputting her thoughts. She has accumulated them for half a year, and now she is still outputting them smoothly.

Moreover, the world's development achievements in the field of controllable nuclear fusion in recent years are still very impressive, which has also brought Su Yu a lot of new nutrients.

She always thought that she was old, but when she focused on it, she felt an unprecedented calmness and concentrated thinking. Su Yu was still very happy and addicted to this feeling.

As time passed, the blank draft paper in Su Yu's office was gradually used up, and then new ones were sent.

During this period, Su Wanxia mailed home a photo of him wearing a military uniform. He still looked very handsome. Although he was half mad at his son all day long, Su Yu was still very proud;

The movie Su Wanju made during the summer vacation was released around the world. Although there were criticisms, it did not affect its ranking as the number one box office in the world. Her daughter, who is studying in college, suddenly became a big star;

Su Wantang's exam ranked first in the whole grade again. Su Yu was very happy. Compared with his eldest son, this younger son made him worry a lot less;

Zhang Xiwen wrote a paper. Su Yu looked at it, nodded with satisfaction, and said: "It's not bad. It may be difficult to publish the "Journal of Qingjiaotang University", but it's still no problem to publish other top journals in the SCI area." of."

"Hehe!" Zhang Xiwen smiled with a hint of excitement and shyness.

Everyone who works hard is reaping the benefits, and Su Yu is the same. This period of time has been like "retreat", spending the whole day at home and in the office, and the ideas in his thesis have gradually become more complete and clear. .

On Monday of the new week, a Denza commercial vehicle followed by two security SUVs drove into the campus of Qingjiao University.

Zhang Tao got off the car and walked into Su Yu's office. He looked at the large office filled with various documents. He glanced at Su Yu who was buried in a book and said with a smile: "I Oh my god! I heard that you have been in seclusion here for almost a year, aren’t you bored?”

Zhang Xiwen glanced at his father, Zhang Tao, and felt that his father did not understand the joy of knowledge at all. He felt that his father was embarrassed. He frowned and said to his father unhappily: "Dad, stop talking, you don't understand." !”

Not only has his son not had any scandals for almost a year, but he also suffered from SCI. More importantly, he has a little more energy. Zhang Tao is very happy. His son will do whatever he says. He nods to his son hurriedly and said: "Okay. Okay, okay! Stop talking, stop talking!"

"Hahaha!" Su Yu smiled, put down the pen in his hand, and stretched.

After being depressed for almost a year, Su Yu was also bored. Su Yu was still very happy when her old friend came to visit her.

After taking a sip of tea, Su Yu stood up and said to Zhang Xiwen: "Your dad was also very good back then. Currently, your dad is the founder of the entire drone design and the application of power generation materials in the aviation field."

"ah?"

Zhang Xiwen was stunned when he heard this. It was obvious that he really didn't know that his father was also awesome.

Comparing Su Yu's achievements with his own poor family, Zhang Tao immediately waved his hand and said, "No more, no more!"

"Why are you here? To see your son?" Su Yu asked Zhang Tao with a smile.

When Zhang Tao heard this, he immediately became nervous like a cat whose tail was stepped on. His face was full of disdain and he said to Su Yu: "Look what he is doing! I came to see you and brought you a box of Maotai. This But the year we were in college was Moutai, let’s drink some together tonight!”

"Tch!" Zhang Xiwen also showed disdain for his father.

The relationship between father and son in China is mostly a mysterious and blunt relationship. Zhang Tao clearly misses his son and is very happy for his son to publish a paper, but he does not show it;

Although Zhang Xiwen was very happy about his father's visit, he also showed disdain for him.

Both father and son are thinking of the other in their hearts, but they show disdain for the other.

As an outsider, Su Yu could only shrug helplessly. Fortunately, he was not so harsh with his son. Although the little bastard made Su Yu half angry, the relationship was not so harsh.
