Siheyuan starts from a good life

Next, the advantages and disadvantages of centrifuge separation of uranium and some technical parameters are summarized, which are roughly as follows.

Advantages: high separation efficiency, up to more than 95%; little impact on the environment; simple process and low equipment cost.

Disadvantages: It is difficult to manufacture and has high technical requirements; a large amount of energy is consumed in the process and the energy consumption is high; and the manufactured centrifuge is dangerous and requires a high degree of safety management.

But the shortcomings are no longer important, because the centrifuge is stronger than anything else, and everyone involved in the centrifuge project is very happy today. At night, the laboratory transferred a batch of supplies from nowhere to provide extra meals for everyone.

When Jiang Yan was producing centrifuges, he thought about the issue of protection. Since there was an international epidemic two years before he traveled through time, Jiang Yan only paid attention to the issue of protective clothing. By the way, he also looked at some special Protective clothing, these data are basically kept in my mind.

Nuclear radiation protective clothing, also called ray protective clothing, is special clothing developed specifically to protect against X and γ rays. Nuclear radiation protective clothing comes in a variety of styles according to different working environments, such as closed type, one-piece type, white coat type, etc. These styles include long sleeves, short sleeves, sleeveless, aprons, glandular protection, lower body protection, etc.

Nuclear protective clothing, also known as nuclear radiation protective clothing, provides shielding against X, γ, β, and α particles. It is a new technology for modifying polyethylene (PE) and polyvinyl chloride (PVC). Ethylene and polyvinyl chloride are resistant to nuclear radiation and can be used as nuclear radiation shielding materials. This polymer lining is made of tantalum as a shielding material. Tantalum is comparable to lead in material attenuation coefficient and resistance to gamma, X-ray and beta radiation, and can effectively absorb radiation. A fabric produced from a polymer backing and natural or synthetic non-woven materials, which is then used to make safety clothing that is resistant to radiation. The garment weighs only one-fifth of traditional lead garments. Its radiation resistance is higher than existing protective clothing. The polymer lining can be modified to make its electronic layer similar to that of heavy metals and can absorb nuclear radiation.

Nuclear protective clothing is a lightweight, durable polymer that provides shielding from low to medium energy gamma radiation, X-rays, high and low energy beta particles and alpha particles.

However, it is obvious that the new technologies of modified polyethylene (PE) and polyvinyl chloride (PVC) cannot be produced by the country under the current conditions. The materials that are most circulated on the Internet are the first-generation protective clothing materials, and Eagle Jiang Yan calculated the materials for Jiang Yan's protective clothing. It should not be difficult to produce them under the current conditions, so Jiang Yan was ready to get them out.

Get it out as soon as possible to ensure the health of these patriotic scientists.

In the next two days, we will mainly focus on summarizing and analyzing the process and results, and forming corresponding technical materials for submission.

"General Engineer Ma, I have designed some protective equipment related to nuclear radiation through thinking these days." After Jiang Yan handed in the summary and analysis materials of the centrifuge that day, he took out the corresponding theoretical design book for nuclear radiation protection equipment.

"Xiao Jiang, do you still understand this?" Mr. Ma always shouted like this in private. Who makes Jiang Yan young? However, this title has no other meaning and seems to be friendly.

"Mr. Ma, I have read some related books in the laboratory during this period and have some ideas in my mind. I like to think too much." Jiang Yan explained.

"It's a good thing to think more, otherwise you could make so many good things! Okay, originally this mission was over, and I had to wait for notification from above;

In this case, let's stay and make the protective equipment before leaving. I will explain the specific situation to the superiors! "Mr. Ma strongly supports Jiang Yan's continued work. This is a good thing. With protective equipment, researchers can be safer.

Not long after, Jiang Yan said goodbye and left. General Engineer Ma handed over all the information on the centrifuge to the superiors.

After the leader obtained all the information and understood the situation, he immediately called the husband.

"Sir, the high-speed uranium enrichment centrifuge that Jiang Yan is responsible for has been successful. The problem of basic fuel for our nuclear weapons research and development has been solved. There is no need to mobilize the masses to waste time and effort to refine uranium in an indigenous way!" The leader excitedly gave Mr. Lai As he spoke, he began to explain the specific situation seriously, with Mr. Ma supplementing the information from time to time.

"Okay, okay! Comrade Jiang Yan has made another great contribution!" After Mr. Lai finished speaking, he planned to call Comrade Yang Guang later.

"By the way, sir, this project has been completed, and I was going to ask you about the follow-up arrangements for Comrade Jiang Yan.

As a result, Comrade Jiang Yan told me that he designed some protective equipment related to nuclear radiation. Therefore, I applied to you, and Jiang Yan continued to carry out subsequent protective equipment projects. "The leader then said seriously.

"Oh? Come on, Comrade Jiang Yan, good, good! Okay, the project has been approved, I wish you immediate success!" Mr. Lai cheered on the phone.

Perhaps he was too happy. After chatting for a long time and exchanging pleasantries, the phone was hung up. Mr. Lai quickly called Comrade Yang Guang’s residence and office. It was already twelve o’clock in the morning.

"Ding ding ding!" The confidential secretary heard this and the phone rang.

"Hello, who are you?"

Mr. Lai revealed his identity, and the confidential secretary went to notify Comrade Sunshine.

"Xiao Wu, what's going on? I heard the phone ringing." Comrade Sunshine asked.

"Chief, sir, I'm calling, saying there's something important." The confidential secretary stated his intention.

Dengdengdeng.

"Lao Lai, what's the matter?" Comrade Sunshine asked on the phone.

"Comrade Sunshine, the uranium high-speed enrichment centrifuge has been successful, and our nuclear weapons research and development progress has been accelerated again! This time it is hosted by Jiang Yan, and Comrade Jiang Yan has done a great job!" Mr. Lai said excitedly on the phone With.

"Okay, okay! What a great thing! Comrade Jiang Yan, I still remember Sa, he is indeed a good comrade!" Comrade Sunshine confirmed as he took a puff of cigarette, his joy was beyond words.

The two chatted for a long time and were very happy. Hearing such a good thing was enough to satisfy them.

In the following time, Jiang Yan began the research and preparation of nuclear radiation protection equipment.

Half a month passed quietly, and the project work on protective clothing was mostly completed.

This day, someone came to the laboratory.

"Comrade Jiang Yan, I am Chen Wanchang, leader of the computer research project team. I have something to ask you!" Chen Wanchang said.

"Hello, Team Leader Chen. If you have anything to say, just tell me!" Jiang Yan replied.

"Okay, Team Leader Zhang, our group is currently studying computer technology. We learned from the above that when you made a new machine tool, you left behind a technical document of the CNC machine tool.

I would like to ask you, do you know computer technology? I would like to invite you to join our group to conduct computer research and manufacturing. "Chen Wanchang explained his intention.

"Yes, I did plan to study CNC machine tools at that time, but the conditions did not allow it, so I submitted some of the ideas I had compiled. I also read some information about computer technology at the time, and I knew a little bit about it." Jiang Yan said modestly Said.

"Comrade Jiang Yan, don't be ridiculous. I was involved in the research on CNC machine tools at that time. You must know more than a little bit about computers. I sincerely invite you to join our group!" Chen Wanchang's expression was serious and formal. Said.

"Okay, Team Leader Chen, I agreed! But now I have a protective clothing project that is almost completed, and I need to take care of it." Jiang Yan replied.

The two communicated for a while. After the communication, Chen Wanchang was in a better mood. It was a wise decision to bring Jiang Yan into his group because he could see that he really understood.
