Liuyun, who has returned to the northwest, has no other mind: the first shipment of iron ore and uranium ore from Australia has arrived at the port of Karachi in Pakistan and is being prepared for rail transportation......

As we all know, the rabbit's housekeeping weapon is a hydrogen bomb that can be stored for a long time, but no one knows, this is the result of a helpless choice: in the uranium ore in nature, the U238 that cannot be fissioned on its own accounts for a considerable proportion, and the U235 that can be fissioned on its own only accounts for a small proportion.

At that time, the practice in foreign countries was to put U238 and U235 into the reactor, and the U238 after neutron shock eventually became fissile Pu239, and it was much easier to separate Pu239 from nuclear fuel.

Therefore, during the Cold War, Eagle Sauce and Mao Bear relied on the continuous production of Pu239, always ready to destroy the world......

However, compared to U235's half-life of 700 million years, Pu239's half-life is only 24,000 years.

Compared with the lifespan of less than 100 years for human beings, 24,000 years is already a long time. However, in order not to waste fuel, the nuclear charge of the hydrogen bomb made of Pu239 is stuck at the lower limit of the critical volume. Although Pu239 is smaller and more powerful than it is critically larger, within a few decades Pu239 will fail and need to be reloaded.

And the U235 that the rabbit wasted the boss to process is not so problematic, and it can be used when it is put in, even if there are more advanced strategic weapons in the future, the nuclear charge of the rabbit family has not yet failed.

The most difficult path is not necessarily the most bitter in the end.

Later, there were only two solutions for large-scale commercial separation of U235, and gas centrifugal separation was also one of the more cost-effective solutions.

However, fortunately, Liuyun still has plenty of time, and the atomic bomb is still theoretical.

In 1929, when I returned to China, the future rabbit nuclear physics masters were still small fresh meat. After inquiring for a long time, he didn't find anyone, so Liuyun could only start another stove and bring his daughter Liu Xuanhui, who studied physics, back to China to grow mushrooms together.

After five or six years of experiments, the Qinghai Institute of Physics led by Liu Xuanhui has basically figured out the principles of fission and fusion.

A few days later, a special train carrying nearly 1,000 tons of uranium ore arrived at Jiayuguan......

On the outskirts of the silver-white iron cans of the Jiayuguan Industrial Zone, on the plains near the foothills of the Qilian Mountains, Liuyun has prepared thousands of hectares of uranium ore for the plant.

In order to manufacture high-speed centrifuges, Jiuquan's stock of high-grade alloys was directly emptied; Because of the formation of the railway network, dozens of electric furnaces, which are gradually reducing output, are urgently transformed into alloy smelting furnaces; Even TNT, which can be produced in unlimited quantities, and the production capacity of nitric acid, the most important raw material, is also divided by uranium ore refining......

As Liu Xuanhui pressed the start button, the uranium ore that had been piled up into mountains was sent to the container by a conveyor belt, where it underwent a series of complex processes such as pickling, filtration, refining, and fluoridation, and finally became UF6 with a low boiling point.

After gasification and pressurization, UF6 is passed into a gas centrifuge, and the allotropes of UF6 are gradually separated after the separation of dense centrifuges in the plant......

A few days later, Liu Xuanhui obtained dozens of kilograms of fuel rods with a concentration of U235 of 3 percent, and happily began the nuclear fuel filling test of the test reactor......

But it didn't take long for Liu Xuanhui to get entangled with Liuyun again: the number of cadmium rods used as neutron reducers is too small......

Liuyun can only wave his hand, and he is powerless in this matter: Huaxia is still a long way from the real land and resources; Cadmium-rich lead-zinc ore reserves in the north are basically zero; Moreover, cadmium is very toxic and not easy to metabolize......

Liu Xuanhui could only watch as a cart of ore turned into a metal rod.

As a result, Liu Xuanhui, who was quite helpless, could only turn her attention to the heavy water of "retreating to slow down neutrons, and entering to deoxygenate and chase the sun", and then to her own "spare tire project" - fast neutron value-added reactor technology.

However, when Liu Xuanhui was about to set up the project, he was rejected by Liuyun, and as a comfort, Liuyun handed over another project plan to Liu Xuanhui.

Liu Xuanhui opened the folder angrily, and was stunned when she saw the title of the project inside.

"Ultra-high purity polysilicon preparation project."

Liu Xuanhui suppressed the ecstasy in her heart, and asked seemingly indifferently: "Ready to go to the integrated circuit?" ”

Liuyun nodded: "Just by counting with both hands, the progress of many projects is very touching, and besides, the calculators assigned to you are almost broken, right?" ”

Liu Xuanhui nodded, but she was a little unwilling: "The atomic bomb and hydrogen bomb project? ”

Liuyun smiled: "There are only big bombs, they can't be sent to other people's homes, rocket and missile projects, just by hand, it's not realistic, you have to go to the computer, as for nuclear weapons and nuclear power projects, you can find suitable people for projects." ”

"So, what about you, Daddy?"

Liuyun glared at Liu Xuanhui angrily: "Old man, I have already given you the answer and the best steps to solve the problem, if you still can't figure it out, then I can't help it." ”

Liu Xuanhui shook his head and stared at Liuyun with some distress: "The matter of Jinling has spread, although others don't know what is going on, but the full-range electronic countermeasure device that was taken out of the laboratory and sent back, the dust composition analysis on it shows that the equipment has been taken to the lower reaches of the Yangtze River and used. ”

Looking at the tears rolling in Liu Xuanhui's eyes, Liuyun sighed: "Some things, even if they cost their lives, have to be done." ”

After a while, seeing that Liu Xuanhui still looked aggrieved, Liuyun had no choice but to ask a question: "You should know about the quantum observer collapse effect, right?" ”

Liu Xuanhui was a little confused, but she still nodded honestly.

Liuyun glanced at the sky outside the window, sighed faintly, turned around and asked Liu Xuanhui with a smile: "If I say that the quantum collapse effect is the dividing point between reality and myth, do you agree?" ”

Liu Xuanhui was stunned: because in her opinion, science is science, and mythology is mythology, but ......

The miraculous quantum collapse is an outlier in the scientific world: when you don't observe, the quantum is superimposed, between right and wrong; But when you look at it, the quantum collapses because of the observer effect, and only shows one state, and when you look at it again, it is another state......

"I often say that the end of science is theology, and that the two end up the same. But ......"

Liuyun sighed: "The theology I'm talking about is not the theology of faith, but the occult. Because all fantasies may be realized after the quantum is unveiled. ”

As he spoke, Liuyun took out a coin from his pocket, put it in the palm of his hand, and unfolded it......
