Chapter 118

The real farewell, no Changting ancient road, no persuading you to get closer to a glass of wine, is in the same morning as usual, but some people stay yesterday.

In the silent universe, a spaceship is sailing slowly, and everything is like a static picture.

Life exists in the universe in the form of infinite cycle. Theists call it reincarnation, while atheists call it material immortality.

The 600 people inside the spacecraft are all of the new civilization at present. Compared with the eternal changes of the outside world, human beings are changing all the time. Time makes everyone who wakes up from hibernation feel the cruelty of time.

But this series of changes is just a series of small beads of light in time and space. From the beginning to the end, in the eternal universe, they are just a moment

Whether you accept it or not, you must accept it!

A week later

Zhang Yuan has come to his workplace.

People always have to face the reality. It's not his style to immerse themselves in sadness for a long time.

"Mr. Zhang, you are really a strong man. You don't lose your job grade of grade 16. Many people will be depressed for a month or so... "Fang Yuhao, the target of his shift, said with great understanding.

"... what has been lost cannot come back. It is more important to focus on the present. What's more, everything in my future is on the ship. " Zhang Yuan smiled reluctantly. "If you keep yourself busy, you won't have so many distractions, will you?"

Fang Yuhao recalled his original days and said with a bitter smile, "Hey, it's true. I kept learning to paralyze myself... Soon, two years passed. Two years is enough to smooth the painful memory. "

"This kind of simple work seems to waste your talent... I believe you can get started soon. In the next half month, I will hand over all the work items to you. Then he was ready to hibernate... "Fang Yuhao said here and stretched out his right hand.

"No problem!"

The two shook hands vigorously.

In theory, the second hibernation will not be so violently impacted, because all the things that should be given up have basically been given up this time. Therefore, Mr. Fang Yuhao is also at ease and boldly preparing for hibernation.

Zhang Yuan's next work is mainly about the control of molten salt reactor, which is a breeder reactor based on fission energy and the main power supply energy in the spacecraft. When most functions are off, the fusion engine is not required to provide energy, and such a little power generation is enough

The structure of molten salt reactor is simpler than that of complex nuclear fusion engine. Zhang Yuan has studied relevant structures, such as Breton thermal cycle, power generation principle, etc., and some simple manual maintenance.

His task is also very simple. If he controls the artificial intelligence of molten salt pile and sends out serious safety alarm, he will be responsible for deciding whether to close the lava pile, whether to wake up a large number of staff from hibernation, etc.

"Yes, it's so easy. If it's a small fault, I'll solve it myself; If something big happens, wake up the big army and don't force yourself. Six hundred of us can't do too much maintenance. "

Fang Yuhao explained seriously, "in fact, you don't have to worry too much. This thing is not an ordinary nuclear reactor. The outlet temperature is about 700 degrees Celsius and does not need water cooling. Therefore, it has good intrinsic safety. Under normal conditions, you don't have to consider that it will explode. "

Zhang Yuan thought for a moment. With a responsible attitude, he asked, "what about the replacement of parts? I'm just worried that the nuclear power plant will automatically stop working because of the loss of parts. It will be very troublesome at that time. It's difficult for us to handle all things after the power failure... "

Fang Yuhao said: "your worry is really very small... However, it was a big year three years ago. The nuclear engine has just been maintained. In theory, the probability of major failure is very small."

"If one molten salt reactor is really broken, you can start another standby nuclear power unit. You have such authority and are responsible for it. "

"I see. What if the third nuclear power unit breaks down?" Zhang Yuan asked again.

"Then start the fourth... There are six molten salt reactor nuclear power units in our spacecraft. When you start the fourth, you should consider waking up the troops."

Zhang Yuan secretly said that he should not be so bad. He has broken down so many nuclear power plants in two years.

These nuclear power plants are designed according to strong and durable standards. Breaking down one is already a small probability event, not to mention two or three.

"The spaceship is still very new... It's a very leisure and simple job anyway. Don't worry too much. " Fang Yuhao saw his idea and said, "when you are bored, you can see what happened on earth, or learn some new theories, and time will pass."

"By the way, I recommend some comedies to you. The popular culture in the 25th Century is different from ours. Some things are still very interesting. The film will be shown at 8 o'clock tomorrow evening at the Z District opera house. "

"It's very good to see the movie" a journey to the west ", as well as the animation" eight dragon balls "and" three migrant workers'... "

Similar collective activities are often held within the community, generally speaking, watching movies and comedies. Literary and artistic performances and other activities can not be carried out because everyone is in a bad mood. Who is willing to sing and dance on the stage?

Zhang Yuan quickly waved his hand: "forget the comedy. It's been so many years and I'm still shooting a journey to the West. It's really unimaginative... I'd better learn some normal knowledge. Learning can bring me happiness. "

……

In this way, under the guidance of Fang Yuhao, Zhang Yuan has learned to check all kinds of data for more than half a month and clearly know what is a big problem and what is a small problem. This is enough.

In addition, he has learned this knowledge himself, so it's very easy to deal with it

After the smooth handover, Fang Yuhao smoothly entered hibernation and Zhang Yuanlai took over the post.

There are six people in this office. They work in three shifts. They work in groups of two, sometimes in groups of one. Everyone is responsible for similar work. In theory, it is enough insurance.

Everyone has their own pastime. Some people like to read comics, while others like to watch movies. The new things produced in the past 180 years are enough for everyone to have fun, especially about the earth's civilized society and the development of science and technology.
