Black Technology Live Room

Zhaicheng Aviation Center, negative 20th floor.

As the bottom floor of Zhaicheng Aerospace Center, it is very quiet here.

Zhang Zhai was leaning halfway on the seat in front of the workbench, holding two pieces of manuscript paper in his hand. There were only a few random lines sketched on the manuscript paper, and a few numbers were recorded beside the lines. This is a simple and even rough paper. design drawing.

Zhang Zhai held the rough design drawing and thought about it, as if thinking deeply: "It seems that it is not that difficult to transform the nuclear reactor or something."

"If all the necessary materials and equipment are in place according to estimates, it may take less than two days for the renovation."

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 casing of the entire nuclear reactor, or more accurately called the pressure vessel, has been disassembled and put together in one place.

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

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

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

The core is composed of hundreds of fuel assembly skeletons, fuel rods and control rods with the same geometric shape and mechanical structure.

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

Fuel rods are naturally discolored nuclear fuel.

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

Uranium rods are uranium concentrates, which 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 rods are actually cadmium rods, which can control the speed of the chain reaction. If there are no control rods, the nuclear reactor will become an atomic bomb directly after it is started.

Don't talk about the shielding layer or containment, even if it is buried a hundred meters underground, it can blow you up.

...

Zhang Zhai glanced at the nuclear reactor that had been disassembled into parts, pondered, pondered, and wrote a few strokes on the manuscript paper.

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

"Wow...wow," Zhang Zhai wrote down on the paper with a pen, raising his head from time to time to look at the picture on the holographic screen, thoughtful.

...

The principle of a nuclear reactor is very simple, that is, external neutrons bombard the uranium nucleus, triggering fission, one nucleus splits into two smaller nuclei, and at the same time 2 or 3 neutrons are released, and then the released neutrons hit the nucleus again, so Repetition is a chain reaction.

(Nuclear fission emits fast neutrons, while those suitable for fission are slow neutrons, so there are moderators around the core to change fast neutrons into slow neutrons.)

Of course, during this period, heat will be released, so there is a closed pipe in the nuclear reactor, which is connected to the outside. The pipe is filled with refrigerant, and the refrigerant circulates continuously to bring out the heat, so as not to cause the nuclear reactor to burn out.

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

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

This process is commonly known as boiling water, also known as boiler burning.

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

"It took only 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."

"Let's try it..." Zhang Zhai became interested, "Take it as laying the foundation for future nuclear research."

"...The core part of the nuclear reactor does not actually take up much space. The key is the shielding layer to prevent nuclear radiation, and the reflective layer to prevent neutrons from escaping takes up too much space... If you ignore the problem of nuclear radiation, or solve the problem of nuclear radiation , the nuclear reactor can be reduced to at least a quarter of what it is now..." Zhang Zhai was talking to himself while recording something on the manuscript paper.

...

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

But at this moment, Hua Menglian, who was at the headquarters of Xihe Technology, was in a bit of misery.

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

"Hi Mr. Hua, I'm from the Kyoto Daily..."

"Snapped!"

Hua Menglian hung up immediately after hearing the word "daily".

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

"Mr. Zhang, Mr. Zhang, you are free, and I helped you avoid the disaster." Hua Menglian said with a wry smile.

"Hey……"

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

As time approached, everyone became more and more expectant and eager, and countless pairs of eyes were fixed on Zhaicheng Space Center.

But... Zhaicheng Aerospace Center didn't talk to death, which made everyone lose their temper.

...

And a group of media reporters who were already eating a hot meal were even more stimulated, screaming and rushing towards Zhaicheng like crazy.

"As long as you can get the exclusive news from Zhaicheng Space Center, get promoted and raise your salary and fire the boss!"

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

but……

Martial law is imposed within two kilometers of the Zhaicheng Space Center, and terminators protect the surrounding area of ​​the Zhaicheng Space Center. Not to mention that media reporters are carrying cameras, they can't rush in even with real guns and short cannons.

So... Hua Menglian is out of luck...

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

"Hi Mr. Hua, I'm Capital News TV..."

"Let me emphasize again that I am not qualified to contact Zhaicheng Space Center, so if there is anything, please contact Mr. Zhang Zhai."

"Oh, Mr. Hua, I think you misunderstood, we want to do an exclusive interview with you."

"Oh?"

"The content of the interview is mainly about your understanding of Zhaicheng Aviation Center..."

"Snapped!"

...

Zhai City Aviation Center, deep underground.

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

"It seems that before the breakthrough in material technology, it is barely possible to change 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 that had been reduced by one-fifth in size on the blueprint, and shook his head.

"A1, inform Academician Gan to help me purchase a batch of materials and equipment to transform the nuclear reactor, and you also send him the list of materials and equipment. If some things cannot be purchased, let him directly look for them." Zhang Zhai leaned on Said lightly on the back of the seat.

"Okay, father."

...

In the laboratory of Zhaicheng Aerospace Center, Gan Xiaohua stared blankly at the "Nvwa" in front of him, but didn't react for a while.

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

Gan Xiaohua was a little lost, and murmured a few words in a low voice.

Finally, with a very weak voice, he said silently: "You are so young, you are really a monster..."

The information on the nuclear reactor has been checked for a long time...
