July 8th.

Dawei Port in a raging storm.

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

After landing from Bangkok, Li Qingye lived in a resort near Bangkok as Andrew, but in fact, he was a soldier disguised as Andrew, and was active in the resort.

And Li Qingye is a small family in Siam, in the Dawei port area of Honsavady.

Kevin said solemnly: "Boss, the third scientific research base has been completed, but we have very few scientific researchers in nuclear physics, and now there are only 17 relevant researchers, and the rest of the personnel are acting as customized soldiers." ”

Li Qingye did not blame for this situation: "It doesn't matter, after all, nuclear physics is a key area of focus for the great powers, and it is right to be careful." ”

"In addition, our uranium coarse material reserves have reached 3,213 tons, and in the third base in the Black Tiger Canyon, we have built three small graphite reactors, but there is currently a lack of low-concentration uranium-235, and there is no formal testing for the time being."

Li Qingye nodded with satisfaction: "This time I came over just to solve the refining problem, where do you store the things that were transported by the Internal Service Department some time ago?" ”

"It's in Black Tiger Canyon."

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

"My subordinates understand."

At noon the next day, Li Qingye and Kevin arrived in Kayah State, which is located in the southwestern part of the Shan State Plateau.

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

In order to cover up the base, Honsawady has set up this area as a nature reserve for Bengal tigers, and also set up a research station on the surface.

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

Especially after dredging, and now it is the rainy season, even a 1,500-ton ship can reach the Black Tiger Town in the Black Tiger Canyon.

After emigrating and relocating, the entire Black Tiger Town is now owned by the Aoba 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 Wu Hu, the head of the base, the group entered the interior of a mine near Black Tiger Town.

I chose this place because of the seclusion and ease of water transportation, and because of the mine.

It is a small lead-zinc mine that has been dug by the previous mine owner with a lot of underground tunnels.

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

And the second phase of the base is also being carried out in secret.

Li Qingye took the elevator shaft converted from the mine and reached 27 meters underground, and if you add a part of the mountain, the depth of some areas here can reach about thousands of meters.

And the nuclear facilities are located beneath the cover of those mountains.

"We have already transferred some of the coarse material here, and we currently have 1,200 tonnes of coarse material in reserve here." Kevin whispered.

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

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

Soon the tram started slowly and drove deeper into the base.

However, the tram did not directly enter the nuclear experiment area and the coarse material storage area, after all, there is a certain risk in these things.

After changing into full-coverage biohazmat suits in the safety area, Wu Hu led them into the nuclear experiment area.

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

Wu Hu summoned Dr. Levi's, the head of the researcher, a former researcher at the Luzon nuclear power plant and one of the few scholars in Luzon who studied nuclear physics, and was secretly sent here early this year through fake death and a makeover.

Levi actually saw 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 this kind of thing!" ”

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

"Can you fix it? Lee, although I admit that you are a top biologist, this is nuclear physics. Levi looked suspicious.

Li Qingye shrugged, then turned his head and instructed Wu Hu: "Take the item 983 that was sent over before and bring it to the special biological laboratory here." ”

"Yes, boss."

After a while, inside the special biology laboratory.

The things that Li Qingye wanted had already been placed in front of everyone.

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

Insert into one of the large barrel Petri dishes.

With the addition of various pheromones and hormones, as well as a steady stream of nutrient solutions, and the temperature was adjusted, the fungus quickly grew in a petri dish.

After an hour of rapid growth, Li Qingye mixed another 100 kilograms of uranium-containing powder with a nutritional paste.

Finally, pour the fungus from the Petri dish into a uranium-containing nutrient paste.

"Let's go!"

"That's okay?" Levi was confused.

Li Qingye replied confidently: "Don't underestimate the adaptability and possibility of living things, you must know that the vicinity of Chernobyl's reactor is now overgrown with fungi. ”

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

"You'll find out tomorrow."

The next day, early in the morning.

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

When I opened the row of lead room cultivation ponds, there was a large reddish-brown fungal aggregate floating on the surface of the cultivation ponds, somewhat similar to the appearance of cyanobacteria after eutrophication.

"The bacteria on the surface are removed, and then the sludge at the bottom of the culture tank is dried."

"Yes."

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

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

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

Obviously, this concentration made Levi feel unbelievable, which was equivalent to being purified a hundred times, and he said excitedly:

"Lee, you're such a genius."

But Li Qingye felt a little dissatisfied:

"This technology is not perfect, and uranium-rich bacteria cannot purify uranium-235 at one time, and it must go through 15 repeated absorptions to refine uranium-235 with a concentration of more than 90%."

"And there is still a small amount of uranium-238 left in the uranium element absorbed by uranium-rich bacteria, and these wastes must be reprocessed."

Hehe! Levi was speechless.

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

It is important to know that bioaccumulation requires only simple cultivation equipment, strains, nutrients, hormones and pheromones.

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

Levi's rough estimate that, according to current data, the cost of producing a kilogram of uranium-235 with a concentration of 90% will not exceed 5,000 gold dollars.

This cost is simply the separation method of hanging centrifuge.
