Chapter 571 Fast Breeder Reactor
After an almost accident in Mongolia, Yang Dongsheng has learned a lot about nuclear physics these days.

In a nuclear reactor, uranium-238, an element that is originally very stable, absorbs one neutron and releases two more electrons, increasing the number of protons by two to 2, which becomes plutonium-2.

Anyone who knows a little about nuclear bombs knows that plutonium-239 is another important raw material for making nuclear bombs.

Yang Dongsheng selected plutonium-239 alone and tried to adjust it upwards. Sure enough, it can be moved. Plutonium-239 is a newly produced element and is not affected by previous adjustments.

It’s just that the plutonium-239 content in this reactor is still a bit low, and there are many oxides. After Yang Dongsheng’s adjustment, the final plutonium-239 content is more than 10%.

Although it is much higher than the previous uranium 235, it is still far from weapon grade.

In the final analysis, the nuclear reaction time this time is too short, and most of the uranium 235 has not been burned.

Yang Dongsheng plans to rebuild a reactor, but the efficiency of producing plutonium-235 in ordinary nuclear reactors fueled by uranium-239 is too low. According to the information, on average, every atom of uranium-235 burned can produce 0.8 atoms of plutonium-239.

Therefore, after the first-generation nuclear reactors were manufactured, humans designed a new type of nuclear reactor—the fast neutron breeder reactor.

The design of the fast breeder reactor is very simple - the fission of plutonium 239 produces a large number of neutrons, which bombard the originally useless uranium 238 in the periphery, turning it into plutonium 239.

Compared with ordinary reactors, in fast breeder reactors, each plutonium-239 atom is fissioned, and 12 to 16 useless uranium-238 can be turned into plutonium-239.

The difficulty with this type of reactor is that there must first be a large amount of plutonium-239.

The half-life of plutonium-239 is 2.4 years. The earth has a history of billions of years. It is difficult to find plutonium-239 in nature.

This is no longer a problem for Yang Dongsheng now.

Yang Dongsheng first enriched metal uranium-238 and plutonium-239 elements, and then separately enriched plutonium-239 at the core position.

In this way, a thick layer of uranium 239 is wrapped outside the plutonium 238.

However, fast breeder reactors are too dangerous. Yang Dongsheng cannot build an effective cooling system. According to the information, fast breeder reactors are also a very violent nuclear reactor, so they cannot be placed in Mongolia. It is far away from China. too close.

Yang Dongsheng decided to put this reactor in a place far away from China, preferably as far away as the Pacific Ocean. Anyway, the government of this place likes to use their common people for experiments, and doesn't care about doing it again.

After arranging everything, Yang Dongsheng thought that he was still very kind. He put this nuclear reactor under a lead mine in Nevada. If Yang Dongsheng was more ruthless, he would put it in the Great Lakes basin...

I don't know what Americans and Canadians think, but Yang Dongsheng feels that he is at least more upright than a certain female star who shouted, "Although they have lost their homeland, they have gained freedom".

The temperature difference between day and night in Mongolia is huge. Although it is midsummer, Yang Dongsheng still feels a little cold when he wakes up early in the morning.

"You send another plane to take Mengmeng and Wenwen over. They are also on vacation! Your daughter called her second aunt yesterday, and the dead girl offered a treasure on the phone and said that she, her brother, and Yang Lin, here is flying and riding a horse." Zhou Ying said.

Mengmeng is the daughter of the second sister, and Wenwen is the daughter of the third sister. They are in higher grades, and the school has arranged make-up classes, so they have late holidays.

If it was just Yang Dongsheng's family who took a private plane to visit Mongolia, they would do anything, but they brought Yang Lin here, and if they didn't bring the second sister and the others, it would appear that they were not separated.

Check out the ranch on the north side today.

After breakfast, just as I was about to get in the car, I saw a large group of dogs running over in a panic with their tails between their legs.

Yang Dongsheng was startled, could it be that the wolves are coming?

Yang Dongsheng was about to take everyone into hiding, when he saw a group of big white geese spreading their wings, stretching their heads, aggressively chasing after the dogs.

Even though the dogs had conceded defeat, the big white geese still refused to finish counting. Several geese blocked a dog that had fallen behind in a corner and pecked vigorously.

Yang Dongsheng was so frightened when he saw the big dog that he urinated.

"Is this our goose?" Yang Dongsheng asked.

Vice President Jiang said, "This is a wild goose! I don't know where it came from. It can fly tens of meters. It especially likes to eat alfalfa and rye grass. When our workers mow the grass, they are often chased by them! "

"Is there such a thing? Don't talk about eating and drinking for free, but also drive away our real masters!" Suddenly, these wild geese really look like people from certain countries, "Then why are you still standing there, grab the iron pot Braised goose!"

Before Yang Dongsheng finished speaking, he saw a middle-aged man wearing glasses, who was already instructing several workers in thick overalls and long gloves to start catching geese.

"The year before last, some workers picked up goose eggs and came back to nest, and the goslings really hatched! Experts say that although the speed of this kind of wild geese is slightly slower than that of domestic geese, the amount of down production is higher than that of ordinary domestic geese, and it is also more cold-resistant and easier to feed. , just feed alfalfa grass and rye grass directly. The feed conversion rate is much higher than that of pigs and cattle, and it can grow in 90 days. Now the company is supporting them to use this wild goose as a basis to breed a high cashmere production. The geese that go out to the market quickly." Vice President Jiang introduced.

Yang Dongsheng remembered that in the report, he seemed to have seen this incident.

Don't look at these big geese soaring fiercely, in fact, their combat effectiveness is very scumbag, and they are still stubborn, they just put their heads down and rush forward.

As long as you wear thick clothes and long gloves, you are not afraid of them pecking, and they are basically useless.

A few workers grabbed the geese by their necks and stuffed them into big cages as if they were harvesting crops.

The wild geese were pecking at the workers, but it was useless, so they thought of running away, but their flying ability is limited, and they have to run up to fly. The streets here are too narrow, there is no room for them to run, and they are about to be grouped. off.

Yang Dongsheng looked at these wild geese and thought that they were here to deliver food, right?

At this moment, there was a goose cry, Yang Dongsheng turned his face and saw Yang Yue riding on the back of a big goose, holding the goose's neck with both hands, opening his mouth to bite down on the goose's head.

"Little ancestor!" Zhou Ying lifted Yang Yue up, but Yang Yue still held on to the neck of the goose.

The plane picked up the second sister and two nieces, and the children went to ride ponies every day.

Yang Dongsheng reorganized the land everywhere, and many problems could not be seen on the [-]D map.

Yang Dongsheng saw through the sports page of the newspaper that Duncan had joined the Mavericks. The contract amount was 6 million U.S. dollars for six years. If he could not sign first and then change, this is the maximum number of years and the highest amount of contract that the Mavericks can sign with him.

In addition to being a little worried about Nowitzki's hair, next season, the Mavericks' lineup is too strong in Yang Dongsheng's opinion. The starting center is Duncan, the power forward is Nowitzki, the small forward Artest, and the point guard. nash.

Only the shooting guard may be weaker, but Reed is a junior who participated in the draft. He is in his 20s this year and should be able to adapt to the rhythm of NBA confrontation.

There are also Brad Miller, Billups, Fred Hoiberg, Najera on the bench, and they can almost put together a good lineup.

If it weren't for worrying about old Nelson having a convulsion, O'Neal was at his peak again, and he could basically celebrate winning the championship in advance.

Of course, it is also possible that the two thorns of Artest and Billups disrupted the atmosphere of the entire team.
