Zhaicheng Aviation Center, negative 20th floor.

As the lowest level underground of Zhaicheng Space Center, it seems very quiet here.

Zhang Zhai was half leaning on the seat in front of the workbench, holding two pieces of manuscript paper in his hand. On the manuscript paper, there were just a few lines vaguely sketched at random, and a few numbers were recorded next to the lines. This was a simple and even rough drawing.

of design drawings.

Zhang Zhai took the rough design and pondered it, as if in deep thought: "It seems that it is not that difficult to transform a nuclear reactor or something."

"If all the necessary materials and equipment are available as estimated, the renovation may not take more than two days."

Zhang Zhai smiled lightly and glanced at the picture on the holographic screen.

At this time, the container that originally contained the nuclear reactor had been violently dismantled.

The alloy shell of the entire nuclear reactor, or more accurately called the pressure vessel, has been dismantled and placed in one place.

Several core components were also exposed and placed in each location in the laboratory.

The core part is naturally the reactor core, where the most important fission chain reaction of a nuclear reactor occurs.

In other words, if there is fission nuclear radiation, it is radiated from the core of the reactor.

The reactor core is composed of hundreds of fuel assembly skeletons, fuel rods, and control rods with identical geometric shapes and mechanical structures.

The fuel assembly skeleton is equivalent to a cube shelf, which divides a large space horizontally and vertically, and its function is to hold fuel rods and control rods.

Fuel rods are naturally the most shocking nuclear fuel.

Zhang Zhai took a look and found that it was a uranium rod, so he directly controlled the Terminator and piled it randomly in the corner of the sealed laboratory.

Uranium rods are concentrated uranium. They have not yet been bombarded by neutrons to trigger a fission chain reaction. Uranium rods in their natural state are not radioactive at all and can be held directly by hand.

…

The control rod is actually a cadmium rod, which can control the speed of the chain reaction. If there is no control rod, the nuclear reactor will directly become an atomic bomb after it is started.

Not to mention the shielding layer and containment, even if it is buried a hundred meters underground, it will blow you up.

…

Zhang Zhai looked at the nuclear reactor that had been dismantled into parts, thought and pondered, and wrote a few more strokes on the manuscript paper.

"It would be simple if we simply follow the previous design requirements, but can we make the nuclear reactor smaller?" Zhang Zhai whispered to himself.

"Crash... crash," Zhang Zhai took a pen and wrote on the paper. From time to time he raised his head and looked at the picture on the holographic screen, thoughtfully.

…

The principle of a nuclear reactor is very simple. Foreign neutrons bombard the uranium nucleus, triggering fission. One nucleus splits into two smaller nuclei, and 2 or 3 neutrons are released at the same time. Then the released neutrons hit the nucleus again, and so on.

Repeatedly, it is a chain reaction.

(Nuclear fission emits fast neutrons, while slow neutrons are suitable for fission, so there is a moderator around the core to convert fast neutrons into slow neutrons.)

Of course, heat will be released during this period, so there is a closed pipe in the nuclear reactor that connects to the outside. The pipe contains a refrigerant, and the refrigerant is continuously circulated to bring out the heat to prevent the nuclear reactor from being burned out.

At the same time, the heat brought out by this pipe can also be used and placed directly under the steam furnace.

Through the steam furnace, the heat energy radiated by nuclear fission is converted into mechanical energy, and then converted into electrical energy.

This process is commonly known as boiling water, or boiling a boiler.

"This nuclear reactor is too large in size, as big as a bus. Although the anti-gravity spacecraft can fully accommodate it, it seems that... it can still be improved." Zhang Zhai said with a smile.

"It only takes three hours from figuring out the nuclear reactor to finding a modification plan. If you want to improve and shrink the nuclear reactor, it's not impossible."

"Try it..." Zhang Zhai became interested, "Just think of it as laying the foundation for future nuclear research."

"...The core part of the nuclear reactor actually does not occupy much space. The key is the shielding layer to prevent nuclear radiation. The reflective layer to prevent neutrons from escaping takes up too much space... If the problem of nuclear radiation is ignored, or the problem of nuclear radiation is solved

, the nuclear reactor can be reduced to at least a quarter of its current size..." Zhang Zhai muttered to himself while recording something on the manuscript paper.

…

Zhang Zhai's subtle voice echoed in the quiet laboratory.

At this moment, Hua Menglian, who was at the Xihe Technology Headquarters, was feeling a little miserable.

"Hello, hello, I'm Hua Menglian."

"Hello Mr. Hua, I am from Kyoto Daily News..."

"Snapped!"

Hua Menglian died immediately when she heard the word "daily newspaper".

"It's really endless!" Hua Menglian said angrily, then she rubbed her forehead and smiled bitterly.

"Mr. Zhang, Mr. Zhang, you are now free. I helped you to avoid disasters." Hua Menglian said with a wry smile.

"Why……"

During this period of time, everyone has been waiting, waiting, and looking forward to Zhaicheng Aviation Center's statement on the moon landing battle and the announcement of the moon landing plan time.

As the time approaches, everyone becomes more and more expectant and anxious, with countless pairs of eyes staring at the Zhaicheng Space Center.

But...Zhaicheng Space Center refused to say anything until death, making everyone lose their temper.

…

The media reporters who were just enjoying the hot meal were even more excited and screamed and rushed towards Zhai Cheng like crazy.

"As long as we can get the exclusive news from Zhaicheng Space Center, we will get a promotion and a raise and fire the boss!"

This sentence is widely circulated in media circles and is deeply recognized.

but……

Martial law is enforced within a two-kilometer radius of the Zhaicheng Space Center. Terminators protect the area around the Zhaicheng Space Center. Not to mention the fact that media reporters are carrying cameras, even with real long guns and short cannons, they cannot rush in.

So... Hua Menglian is unlucky...

"Hello, hello, I'm Hua Menglian."

"Hello, Mr. Hua, I am Capital News TV..."

"I would like to emphasize again that I am not qualified to contact the Zhaicheng Space Center, so if you have any questions, please contact Mr. Zhang Zhai."

"Oh, Mr. Hua, I think you misunderstood. We want to give you an exclusive interview."

"oh?"

"The content of the exclusive interview is mainly about your views on Zhaicheng Aviation Center..."

"Snapped!"

…

Zhaicheng Aviation Center, deep underground.

Zhang Zhai shook his head helplessly: "Although the Terminator is not afraid of nuclear radiation, if nuclear radiation affects the moon base, it will be a problem in the future."

"It seems that before there is a breakthrough in material technology, we can barely modify the internal structure of the nuclear reactor and make the entire nuclear reactor smaller."

Zhang Zhai shook the manuscript paper in his hand, looked at the nuclear reactor on the design drawing that had been reduced by one-fifth of its size, and shook his head.

"A1, inform Academician Gan to help me purchase a batch of materials and equipment to modify the nuclear reactor. Send him the list of materials and equipment. If there are some things that cannot be purchased, ask him to go directly to the top." Zhang Zhai leaned on him.

He said relaxedly on the back of the seat.

"Okay, Father."

…

In the laboratory of Zhaicheng Space Center, Gan Xiaohua stared blankly at the "Nuwa" in front of him, unable to react for a moment.

"So fast? It's less than a day, right? Is he sure?"

Gan Xiaohua was a little absent-minded and murmured a few words in a low voice.
