Uranium metal has large reserves in nature, but it is unevenly distributed and difficult to extract. Only a few countries produce it.

1 Generally speaking, uranium, an element with a half-life period calculated in billions, does not radiate very strongly in a stable state. As long as there is no direct contact, it can be said to be very safe.

However, uranium 1 generally has associated elements, such as radium, and radium produces radon, which exists as a gas and has a decay cycle of 38 days. It can cause lung cancer after entering the respiratory tract.

Without much trouble, after the gold mines were reorganized, the Royal Mining Company began mining activities.

"This is protective clothing? What's the difference? It must be very hot to wear." Liu Bicheng held up the integrated white clothing.

"You should be worried about the poison in the mine. Look at this mask." The deputy director picked up the mask. "It's a fully enclosed mask with an oxygen bottle for oxygen supply. It's better than the gas masks used by the military."

"The miners are here." The assistant called outside the door.

"We'll go there in a moment." Liu Bicheng put on his clothes. This is the uniform of Nanhua employees.

"If there is poison in the mine, will it cause greater casualties? These people are different from natives after all." asked the deputy director.

"Look again, if there are too many deaths, it will be a mining disaster. It won't pay much money, and he is not one of our people." Liu Bicheng put on his hat and left the cabin.

In the open space, 500 Tu'ao workers were huddled together in a mess. They were the workers recruited by Nanhua.

"Hello, I am the person in charge of this mine and also your boss." Liu Bicheng stood on a high place and shouted with a primitive loudspeaker.

"You should know your responsibilities, dig for ore, and then report to your superiors how much we dug." As soon as Liu Bicheng said these words, the already chaotic mess became even more chaotic.

!

Because some of them did come with a mission, such as assessing the value of this gold mine.

"I don't care what tasks you have! In addition to gold mines, we also have many minerals to mine. I will pay you according to the number of ores you dig out." Liu Bicheng took out a 1 pound gold coin.

"Work six days a week and complete the task every day, and you will get 1 pound." Liu Bicheng's words caused an uproar.

This price is not high in Australia, where labor wages are very high, and is even a little low.

"Complete additional tasks, for example, the workload in one day is 1,000 kilograms, and the workload in one week is 6 tons. If you dig 7 tons, you can get 1 pound and 10 shillings. If you can complete 10 tons in one week, you will

You can get 3 pounds!" Liu Bicheng threw the pound in his hand, causing chaos.

"Work hard, you bastards!" After saying that, he stepped down.

"Is this salary too high? Why not increase the basic salary..." the deputy director said.

"Why should we let them make money?" Liu Bicheng shrugged: "This is not done in the country, the labor union, the Construction Corps, the Ministry of Industry, the Ministry of Education, not here. Your Majesty taught me this method."

"Your Majesty?" In the eyes of the Southern Chinese, Liu Yiming was a strict but very benevolent emperor - only to the Southern Chinese.

"Some smart people among them will unite, divide labor and cooperate, and even achieve a salary of 5 pounds per week, so what?" Liu Bicheng took off his clothes and wiped his sweat.

"The nearest city from here is Darwin, 220 kilometers away. Except for our convoy, no one else will come. The food, clothing, housing and transportation of these people are all in our hands. Are you still worried that you can't squeeze the money out of their hands?"

"In addition to eating and drinking, when they have money, they will want to spend money in brothels, pubs, and casinos. When they leave, they won't be able to take much money with them."

"Is this so?" The deputy factory director was shocked.

"The construction machinery will arrive in one month. When the loan plan is launched, they will rush to buy it." Liu Bicheng picked up a bottle of wine.

"The lowest quality sugarcane wine only costs 5 cents a bottle in Nanhua. If it only costs 3 cents in the place of production, here you can sell it for 5 pence a cup. 1 pound 240 pence, 1 pound 500

Divide the money and calculate the profit yourself."

The deputy factory director was assigned after he retired and is a factory protection personnel.

After all, Tu'ao is in such chaos right now, there are so many robbers of all kinds, and there have been fights between robbers and the British army.

…………

"In the first week, we need to clear out the mining area, wait a moment." The staff leading the team arrived at the edge of the mining area and stopped those who wanted to enter.

"Why?"

"What's wrong?"

"I saw no golden mountains or rivers."

boom!

The flat ground in the distance suddenly lifted up, and a huge explosion echoed through the sky.

"It seems that this blasting failed, but this area still needs to be cleaned up. Come on guys, don't leave the rubble on the upper level. Clean it up and leave." The staff frowned at the huge explosion.

This means that the blasting failed. A successful blasting would result in huge vibrations and muffled thunder. In such a large scene, a lot of energy is consumed.

"Do these gravels count as money?" This is the only question that miners are concerned about.

"Only the basic salary is calculated, but if you don't clear away the rubble at the upper level, you will never be able to touch the gold at the lower level, and you will never get performance pay." The staff looked like you were doing whatever they wanted.

After receiving assurances, the miners began work.

There is also uranium in the upper layer, but the content is below 001 and has no mining value. The highest quality ore in the mining area can have a content of 07, which is 7 kilograms of 8 uranium oxide per ton.

say-app&——

(There are not many high-quality ores.)

On average, the content of uranium 235 is 0.711, that is, 1 ton of uranium metal contains 711 kilograms of uranium 235 - the only element in nature that can undergo controlled nuclear fission.

The critical mass of uranium 235 is 52 kilograms (from the information I searched, this value was mentioned more often when there is no neutron reflecting layer). Only when the critical mass is reached can a nuclear explosion occur.

But there is a simpler (and fatal) way.

To build a nuclear reactor, the burning of nuclear fuel is the fission of uranium 235. In this case, part of the uranium 238 will capture a neutron to form metallic plutonium.

Metal plutonium is also based on the principle of an atomic bomb. The critical mass is only ten kilograms and is even more powerful. Most importantly, it saves the need for thousands of centrifuges to run for several years.

It's just more expensive, because metallic plutonium has strong radiation, so you can just let the natives do it when the time comes.

(So ​​I think Japan’s desire to destroy us will never die, and nuclear waste can be used to extract metal plutonium = atomic bomb.)

………

Time came to the end of June, and Liu Yiming and Wang Yang were discussing the reform of the Army, mainly to expand the establishment of the brigade and reduce the establishment of the regiment.

explain,

Increase the defensive capabilities of Arabia and Hawaii, so that when facing enemy attacks, they can persist until the navy gains control of the sea.

"The British have invaded Pretoria and announced the annexation of the Transvaal." Secretary Wang came in with the documents.

"Look, don't you want money? Here comes the money." Liu Yiming changed his bitter expression.

Because the navy will receive more support in the future, the military will highlight the status of a little mother, and Wang Yang will come over to use the excuse of reform to spend money.

RMB 22 million is actually very wealthy to support a dozen infantry divisions, but the level of mechanization of these ten divisions is not low, and further mechanization transformation is needed.

It is foreseeable that the Army will definitely have a hard time in the next few years, so Wang Yang and Yang Tao are taking turns spending money. Liu Yiming has already agreed with the Army's idea of ​​finding customers to export weapons.

"After the British fought the Boer War, their strategic goal should be to return to Southeast Asia. Our situation will not be too good." Wang Yang did not understand why Liu Yiming was happy.

Of course Liu Yiming was happy. The British announced that the first half was over, which meant that the second half, which consumes the bulk of military expenditures - the security war, had begun.

This was also the first guerrilla war in the world. In the end, it failed because the Boers had no foundation. However, the results were great. It allowed Britain to see its own weaknesses clearly and promoted Britain and France to get closer.

"I agree to allocate an additional 1.6 million for the adaptation, but we can't allocate it now. We have to wait a few days." Liu Yiming didn't say why. He got Wang Yang away first and then called Jiang.

prosperous.

pp!

"The British say the war is over and everything is business as usual. Can you contact our people?" Liu Yiming said.

"I have already contacted the person in charge of the Cape District, and the results have been fruitful." Jiang Wang showed a rare smile.

It's not easy to be in the intelligence service. Spies rarely get any honors, and this job requires people who have the highest sense of identification with Nan Hua to do it.

Going deep into the enemy camp, you not only have to endure inhuman abuse after being exposed, but you also have to endure being separated from your family, the abuse and incomprehension of your comrades, and the psychological pressure is extremely high. Although it is useless, having money can help their families be better.

.

"How's the loss?" Liu Yiming crossed his arms.

"Three strongholds were discovered, and six people died. The ashes of four of them have arrived in Cape. When the ship comes back, two corpses are still buried and cannot be excavated for the time being." Jiang Wang said calmly.

"Do you have any relatives?" Many people don't even have any relatives. For example, Wang Tinghan was alone after his mother died.

"The family has made arrangements. The child will enter the Boy Scouts and enter the university or military academy through normal channels." In order to maintain confidentiality, they are not soldiers and do not meet the martyr award process.

"After returning, transfer the files to the special forces register, and award them with a fourth-level medal, the title of martyr, and the title of officer." This is the only thing Liu Yiming can do. Their mission may not be made public until 50 years later.

"Yes!" Jiang Wang stood upright.

"What was the result?" Liu Yiming asked.

"There are currently 80 tons of gold scattered across the Cape, and this amount is still increasing." Jiang Wang said.

This amount of gold is almost 55 million, and 80 tons seems like a lot. In fact, the Rand Gold Mine currently produces hundreds of tons of gold every year. It will continue to be produced in later generations, with a cumulative output of more than 35,000 tons.

"After the goods are shipped back, two million will be allocated to the Army. The Army will borrow the money from the intelligence department and pay it back in five years." Liu Yiming nodded.

The 80 tons of gold is just a by-product, mainly allowing Britain to consume more.

"By the way, the Rand Gold Mine also produces uranium. The output is not large, but one batch is used as slag and is piled on the slag pile." Jiang Wang added, thinking of Liu Yiming's recent actions in Australia.

"Look for any glass product company and discuss the purchase." Liu Yiming reacted immediately.
