Chapter 142 The Third Base
7 month 8 day.

Dawei Port in a storm.

Kevin, who is in charge of the work in this area, is reporting his work to Li Qingye in an underground bunker.

After landing in Bangkok, Li Qingye took the identity of Andrew and stayed in a resort near Bangkok. In fact, it was a soldier who pretended to be Andrew and was active in the resort.

As for Li Qingye, as a small family in Siam, the Dawei Port area in Hongshawadi.

Kevin said cautiously: "Boss, the third scientific research base has been completed, but we have very few scientific researchers majoring in nuclear physics. Now there are only 17 relevant researchers, and the rest are filled with customized soldiers."

For this situation, Li Qingye did not blame: "It doesn't matter, after all, the nuclear physics major is the focus of the big powers, and it is right to be careful."

"In addition, our crude uranium reserves have reached 3213 tons. In the third base of Black Tiger Canyon, we have built three small graphite reactors. However, there is currently a lack of low-concentration uranium 235, and there is no formal test yet."

Li Qingye nodded in satisfaction: "I came here this time to solve the refining problem. Where do you store the things that the Internal Affairs Department transported some time ago?"

"It's in Black Tiger Canyon."

"Then when the rain stops, we will head to Black Tiger Canyon."

"My subordinate understands."

At noon the next day, Li Qingye, Kevin and others took the ship and arrived in Kayah State, which is located in the southwest of the Shan State Plateau.

The Black Tiger Canyon, where the third base is located, is a very inconspicuous small valley plain in the mountain valley of this plateau.

In order to cover up this base, Hongshawadi set up this area as a nature reserve for Bengal tigers, and also set up a scientific research station on the bright side.

The advantage of this place is that it can be directly entered by a 500-ton ship through a tributary of the Salween River.

Especially after dredging, and it is now the rainy season, even a 1500-ton ship can reach Heihu Town in the Black Tiger Canyon.

After immigration and relocation, the entire Heihu Town is now a member of the Qingye Group, and there are no outsiders at all, ensuring the secrecy here.

After Li Qingye came to Black Tiger Town, he did not appear in front of ordinary employees, and his identity was also an inspector sent by the headquarters.

Under the leadership of base chief Wu Hu, a group of people entered a mine near Heihu Town.

I chose this place because of the concealment and the convenience of water transportation on the one hand, and the mine on the other.

This is a small lead-zinc mine, and many underground mines were dug by the previous mine owner.

After the second transformation, all the mine tunnels were reinforced, expanded, and modified, and became the current underground base.

Moreover, the second phase of the base project is also being carried out in secret.

Li Qingye took the elevator shaft transformed from the mine and reached the 27 meters underground. If a part of the mountain is added, the depth of a part of this area can reach thousands of meters.

The nuclear facilities are set up under the cover of those mountains.

"We have already transferred some of the rough materials here, and currently there are 1200 tons of rough materials in reserve here." Kevin introduced in a low voice.

At the bottom of the elevator shaft, after taking the elevator, there is a small underground station, where trams are used as a means of transportation.

Wu Hu hurriedly opened the door of the car: "Boss, let's get in the car!"

Soon the tram started slowly and drove towards the depths of the base.

However, the tram did not directly enter the nuclear test area and the crude material storage area. After all, these things have certain risks.

Wu Hu took them into the nuclear test area after changing into full-coverage biological protective suits in the safe area.

A group of researchers, also wearing full-body protective suits and special resin transparent space helmets, were in front of a small centrifuge.

Wu Hu called the head of the researcher, Dr. Reeves, who was a former researcher at the Luzon Nuclear Power Plant and one of the few scholars in Luzon who studied nuclear physics. He was secretly sent here early this year through suspended animation and a facelift.

Levi's actually met Li Qingye in Luzon, and he said helplessly, "Li, this small centrifuge can't separate uranium-235 at all. You should understand the danger of such a thing!"

"Don't worry! I will solve the problem of uranium enrichment." Li Qingye replied confidently.

"You can solve it? Li, although I admit that you are a top biologist, but this is nuclear physics." Levi's expression was suspicious.

Li Qingye shrugged, then turned his head and instructed Wu Hu: "Take the item No. 983 that was delivered earlier, and bring it to the special biology laboratory here."

"Yes, boss."

After a while, in the special biological laboratory.

What Li Qingye wanted was already placed in front of everyone.

He opened the suitcase, which contained rows and rows of storage test tubes in which special frozen fungal spores were stored, and took out one of them.

Insert into one of the large barrel Petri dishes.

After adding various pheromones and hormones, as well as a steady stream of nutrient solutions, and adjusting the temperature, the fungus quickly grew in the petri dish.

After an hour of rapid growth, Li Qingye mixed one hundred kilograms of uranium-containing powder and nutrient paste together.

Finally, the fungi in the petri dish were poured into the uranium-containing nutrient paste.

"Let's go!"

"Is that all right?" Levi's was at a loss.

Li Qingye replied confidently: "Don't underestimate the adaptability and possibility of living things. You must know that the area around the Chernobyl reactor is now full of fungi."

Levi's, who was skeptical, muttered to himself: "Can biotechnology really complete uranium enrichment?"

"Tomorrow you'll find out."

The next day, early in the morning.

Levi's couldn't wait to come over, obviously he also wanted to know how effective the bio-enrichment technology was.

Open the row of lead room cultivation ponds, and there is a large reddish-brown fungal aggregate floating on the surface of the cultivation pond at this time, which is somewhat similar to the appearance of cyanobacteria after eutrophication.

"Remove the bacteria on the surface, and then dry the sludge at the bottom of the cultivation pond."

"Yes."

The bacteria floating on the surface are removed, and then the sludge at the bottom of the pool is filtered and dried, turning into hundreds of kilograms of mud.

Levi's led people to measure the uranium-235 content of the mud.

After more than five hours of intensive testing, the content of uranium 235 in the mud finally came out, and its concentration reached about 7.2% to 8.3%.

Obviously, this concentration made Levi's feel unbelievable, which is equivalent to being purified hundreds of times. He said excitedly:

"Lee, you are such a genius."

But Li Qingye felt a little dissatisfied:
"This technology is not yet perfect. Uranium-enriched bacteria are currently unable to purify uranium-235 at one time. Only after 15 repeated absorptions can they extract uranium-90 with a concentration of more than 235%."

"And among the uranium elements absorbed by uranium-enriching bacteria, there is still a small part of uranium-238 remaining, and these wastes must be processed again."

hehe!Levi was speechless.

In his opinion, this technology is already very powerful. Even if it needs to be absorbed repeatedly 15 times, it is faster and cheaper than the centrifuge separation method, and it can even be said to be cheap.

It should be known that the bioconcentration method only needs simple cultivation equipment, strains, nutrients, hormones and pheromones.

The cost of these things is not high for Homo sapiens.

Levi's roughly estimated that according to the current data, the cost of producing one kilogram of uranium-90 with a concentration of 235% will not exceed 5000 gold dollars.

This cost is simply a centrifuge separation method.
