Rafe has arrived with his negotiating team, and now they are visiting the desalination plant in Huludao.
Looking at the fresh water in the reservoir, constantly flowing 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, I wonder when President Zhu will come back?" Rafe turned to the vice president of the water group and asked.
"Maybe around June 4th! It is true that the sales contracts for seawater desalination plants are similar. There is no need to wait for Mr. Zhu to come back."
Rafe shook his head quickly: "I want to talk to President Zhu in person, it's okay, I can wait."
"Oh well!"
Rafe hoped that Zhu Jianguo would come back later. He knew that the negotiation this time would most likely turn out to be bad. He was just stalling for time, treating it as a trip at official expense.
So Rafe didn't care about the negotiations at all and just went sightseeing in Huludao City.
At this time, Zhu Jianguo was inspecting the laying of the central water supply trunk line in Shanxi Province, and of course he had no time to pay attention to Tu'ao's negotiating team.
The central water supply trunk line has now been advanced to the vicinity of Wenshui County in Luliang City. In fact, the central water supply trunk 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 almost parallel to the railway line.
Entering Qin Province from Jinzhong City - Wenshui County - Luliang City - Liulin County - Wubao.
"Have you encountered any trouble in the project?" Zhu Jianguo asked, looking at the progress chart.
Shi Hai, the middle line manager of the pipeline construction company, quickly replied:
"The main problem is the terrain. The terrain in Jin Province is relatively harsh, which has brought some inconvenience to our construction. Now our line has entered the Luliang Mountains."
"Work hard and try to communicate with the railway construction group if possible."
"We have always been in contact with the railway department."
"By the way, how are you preparing for the Yellow River Bridge?" Zhu Jianguo asked.
After all, the central water supply trunk line, after passing through Liulin County, reaches Wubao in Qin Province, where it must pass through the Yellow River.
"We have discussed with the Planet Group and plan to build a cross-river bridge using the cross-strait bridge model." Shi Hai opened the holographic bracelet and explained.
Zhu Jianguo looked at the simulation design model and nodded with satisfaction.
Although the laying 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 lines is different. The northern line is a flat desert like Gobi Desert or grassland. The terrain is not complicated, but the climate is a bit harsher.
The middle line needs to pass through the Taihang Mountains, Taiyuan Basin, Luliang Mountains, Yellow River, etc. The terrain is several times more complex. In addition, the areas that the middle line passes through are densely populated, and the issue of land acquisition and compensation is also more troublesome.
…
the other side.
Near Hualien, East Island.
In a research institute of Galaxy Technology.
Dr. Yuan Quan and others were wearing thick protective clothing and watching the testing in the laboratory.
As the continuous flow of seawater passes through the film, the radiation dose on the radiation dose detector nearby is soaring.
"Doctor, the concentration has reached the critical point."
"Replace the film." Dr. Yuan Quan immediately ordered.
The researcher quickly pressed the membrane switching button, and the membranes in the filter pool were instantly switched.
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 7o%.
"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 high-concentration uranium will quickly destroy the molecular structure of the film.
No matter what kind of material the film is made of, once it is exposed to strong radiation for a long time, no matter how powerful the film is, it will turn into dregs.
"Judging from the filtration performance, the filtration efficiency of the new membrane was 1oo% for the first time, 97% for the second time... and only about 37% of the filtration efficiency was left for the eighth time." After the researcher finished speaking, he handed the report to Dr. Yuan Quan.
.
"That's all we can do for the time being." Regarding the problem of radiation exposure, she has no solution for the time being.
"By the way, doctor, this is the production report."
After taking it and looking through it, the output of this laboratory factory is approximately 76o kilograms of yellow cake (concentration 7o%) per year.
After these yellow cakes are produced, part of them are reserved by Galaxy Technology, and the remaining part is sold to China National Nuclear Corporation.
Dr. Yuan Quan left the laboratory and came to an office building one kilometer away. Only then did she take off her protective clothing. The radiation dose of high-concentration yellow cake was very large, so these protective clothing were necessary.
Zhang Silin, the deputy director in charge of the management of the institute, saw Yuan Quan coming back and poured her a pot of tea.
"Dr. Yuan, how was today's experiment?"
After taking a sip of tea, Yuan Quan said helplessly: "The film has been successful, but its service life is a big problem."
"Can it still only be used about ten times?" Zhang Silin knew these data.
Yuan Quan nodded: "The radiation dose of high-concentration yellow cake is too high and will quickly destroy the molecular structure of the film. This is an unavoidable problem."
"It's not bad! 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 was talking about. Although the Plasma Research Institute already had room-temperature conductors, there had been no breakthrough in the problem of neutron irradiation. Who knows how to solve this problem.
"Perhaps nuclear fusion power generation will really be fifty years away from us forever!" Yuan Quan joked.
"By the way, has the output been calculated?"
"Out."
"about how much?"
"Using one hundred square meters of filter membrane, we can produce about 760 kilograms of yellow cake a year, with a concentration of about 70%." Yuan Quan replied directly.
"Is this so?" Zhang Silin heard this data and opened the holographic bracelet to calculate the cost.
The uranium filter membrane costs 3700 yuan per square meter. Due to the radiation dose problem, the membrane is replaced about twice a day on average. The cost of the film to produce 76o kilograms of yellow cake is 1oo*365*2*37oo=2701 million yuan.
The average price is about 350,000 Chinese yuan per kilogram. Obviously, this cost is not cost-effective. After all, the international yellow cake price is about 50 to 300 Chinese yuan per kilogram.
"This cost is too high. If it is used to produce mushrooms, it is quite cost-effective, but if it is used for electricity, it is not cost-effective." Zhang Silin said helplessly.
"Take your time! I can't eat hot tofu in a hurry." Of course Yuan Quan knew that the cost was too high, and as a civilian, electricity could not be paid for.
As for why it is more suitable to make mushrooms, the main reason is that the film can quickly produce yellow cake with a concentration of 99.999%.
When the yellow cake concentration reaches more than 8o%, the refining cost is calculated per 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 costs hundreds of thousands of dollars.
For yellow cake produced by the thin film method, only about 1 million to 1.2 million per kilogram can be obtained to obtain yellow cake with a concentration of 99.999%.
Therefore, the thin film method can replace the centrifugal method as a method for refining high-concentration yellow cake. However, in civilian applications, high-concentration yellow cake is not needed, and the cost of hundreds of thousands per kilogram is outdated.
"Doctor, please give me the data and I will upload the experimental report." Zhang Silin put down the teacup and said.
Dr. Yuan Quan nodded: "Okay, I will sort it out for you later."
