Galactic Tech Empire

Chapter 300 Breakthrough Again
Huludao City, Headquarters of Dongyin Water Group.

Raff has arrived with the negotiating team, and now they are visiting the desalination plant in Huludao.

Looking at the fresh water in the reservoir, which kept coming in and out, he had to admit that Dongtang was the world's number one in seawater desalination technology, the undisputed number one in the world.

"Mr. Zhang, when will President Zhu come back?" Laf turned his head and asked the vice president of the Water Affairs Group.

"Maybe around June 6th! It is true that the sales contracts for seawater desalination plants are similar, so there is no need to wait for Mr. Zhu to come back."

Raff shook his head quickly: "I want to talk to President Zhu in person, it's okay, I can wait."

"OK then!"

Raff hoped that Zhu Jianguo would come back later. He knew that the negotiation this time would probably be messed up, and he was just delaying time, so he treated it as a government-funded trip.

So Raff didn't care about the negotiation at all, and went directly to visit the mountains and rivers in Huludao City.

At this time, Zhu Jianguo was inspecting the laying of the central water supply main line in Shanxi Province, so of course he had no time to pay attention to the negotiating team in Tuao.

The main water supply line of the central line has been advanced to the vicinity of Wenshui County in Luliang City. In fact, the main water supply line of the central line basically coincides with the railway route.

For example, the current planned route of the central water supply trunk line in Luliang City is laid along the railway line almost in parallel.

Enter Qin Province from Jinzhong City - Wenshui County - Luliang City - Liulin County - Wubao.

"Did the project encounter any trouble?" Zhu Jianguo asked looking at the schedule.

Shi Hai, the person in charge of the central line of the pipeline construction company, quickly replied:

"The main problem is the terrain. The terrain in Jin Province is relatively complicated, which brings some inconvenience to our construction. Now our line has entered the range of Luliang Mountains."

"Get over it more, if possible, you can communicate with the railway construction group."

"We have been in touch with the railway department."

"By the way, how are you preparing for the Yellow River Bridge?" Zhu Jianguo asked.

After all, the main water supply line of the central line, after passing through Liulin County, is Wubao in Qin Province, where it must pass through the Yellow River.

"We discussed with Planet Group, and we plan to use the model of the Strait Bridge to build a bridge across the river." Shi Hai opened the holographic bracelet and explained.

Zhu Jianguo looked at the simulated design model and nodded in satisfaction.

Although the laying speed of the central line is much slower than that of the northern line, Zhu Jianguo is still quite satisfied with the current construction progress.

After all, the terrain of the two routes is different. The northern route is flat desert Gobi desert or grassland. These terrains are not complicated, but the climate is a bit harsher.

The central line needs to cross the Taihang Mountains, Taiyuan Basin, Luliang Mountains, Yellow River, etc. The terrain is several times more complicated. In addition, the areas passed by the central line are densely populated, and the issue of land acquisition compensation is also more troublesome.

……

the other side.

East Island near Hualien.

In a research institute of Galaxy Technology.

Dr. Yuan Quan and others are wearing thick protective clothing and watching the test situation in the laboratory.

As a steady stream of seawater passes through the membrane, the radiation dose on the radiation dose detector is rapidly increasing.

"Doctor, the concentration has reached the critical point."

"Replace the membrane." Dr. Yuan Quan ordered immediately.

The researcher hastily pressed the membrane switching button, and the membrane of the filter pool was switched instantly.

The staff did not dare to neglect, and quickly operated the robot to remove a film full of uranium.

Then quickly carry out chemical treatment to produce a yellow cake with a concentration of about 70%.

"What's the condition of the film?" Yuan Quan is most concerned about the service life of the film.

The reason is very simple, the strong radiation of highly enriched uranium will quickly destroy the molecular structure of the film.

No matter what kind of material the film is made of, once it is in contact with strong radiation for a long time, no matter how powerful the film is, it will turn into bean curd.

"From the perspective of filtration, the filtration efficiency of the brand new membrane is 100% for the first time, 97% for the second time...only about 37% of the filtration effect is left for the eighth time." After finishing speaking, the researcher handed the report to Dr. Yuan Quan .

"That's the only way to go for the time being." Regarding the problem of radiation exposure, she has no way to solve it for the time being.

"By the way, doctor, this is the production report."

After taking it over and looking it up, the output of this laboratory factory is about 760 kg of yellow cake (concentration 70%) per year.

After these yellow cakes are produced, some of them are stored by Yinhe Technology, and the rest are sold to CNNC.

Dr. Yuan Quan left the laboratory and came to the office building one kilometer away. She took off her protective clothing at this time. The radiation dose of high-concentration yellow cake is very large, and these protective clothing are necessary.

Zhang Silin, the deputy director in charge of the institute's management, saw Yuan Quan come back and poured her a pot of tea.

"Dr. Yuan, how is today's experiment?"

After taking a sip of tea, Yuan Quan said helplessly: "The film has been successful, but the service life is a big problem."

"Can it still only be used about ten times?" Zhang Silin knew the data.

Yuan Quan nodded: "The radiation dose of high-concentration yellow cake is too high, which will quickly destroy the molecular structure of the film. This is an unavoidable problem."

"It's okay! At least it's better than the Plasma Research Institute, they can't do anything with neutron irradiation now." Zhang Silin said with a smile.

Of course Yuan Quan knew what he said. Although the Plasma Research Institute already had room-temperature superconductors, there was no breakthrough in the problem of neutron irradiation. God knows how to solve this problem.

"Maybe nuclear fusion power generation is really 50 years away from us forever!" Yuan Quan joked.

"By the way, has the output been calculated?"

"Out."

"about how much?"

"Using a filter membrane of 760 square meters, about 70 kilograms of yellow cake can be produced a year, and the concentration is about [-]%." Yuan Quan replied directly.

"Is that so?" Zhang Silin heard the data and opened the holographic bracelet to calculate the cost.

铀过滤薄膜每平方米3700华元，由于辐射剂量的问题，薄膜平均一天更换两次左右，那生产760公斤黄饼的薄膜成本就是100*365*2*3700=2.701亿华元。

The average cost is about 35 Huayuan per kilogram. Obviously, this cost is not cost-effective. After all, the international price of yellow cakes is about 400-2000 Huayuan per kilogram.

"The cost is too high. If it is used to produce mushrooms, it is quite cost-effective, but if it is used to generate electricity, it is not cost-effective." Zhang Silin said helplessly.

"Take your time! You can't eat hot tofu in a hurry." Of course, Yuan Quan knew that the cost was too high, and it would be beyond his means for civilian power generation.

As for why mushrooms are made, it is more suitable, mainly because the film can quickly produce yellow cakes with a concentration of 99.999%.

However, if the concentration of yellow cake reaches more than 80%, the refining cost is calculated by every percentage point. The higher the concentration, the higher the cost.

Yellow cake with a concentration of 99.999% is calculated in grams, and one gram is hundreds of thousands of Wah.

The yellow cake produced by the film method only needs about 100-120 million per kilogram to obtain a yellow cake with a concentration of 99.999%.

Therefore, the membrane method can replace the centrifugal method as the extraction method of high-concentration yellow cake, but in the invention of civil power generation, high-concentration yellow cake is not required, and the cost of hundreds of thousands per kilogram is outdated.

"Doctor, you give me the data, and I will upload the experiment report." Zhang Silin put down his teacup and said.

Dr. Yuan Quan nodded: "Yes, I will sort it out for you later."
