“The island nation’s cabinet holds an emergency meeting on Edo Electric Power Company’s sewage treatment”

"Edo Electric Power Company announced that its sewage treatment capacity has reached its upper limit and cannot afford the huge maintenance costs of storage tanks."

"Zhongshan Jiuer said that it will take the issue of sewage discharge seriously."

On August 10, the Edo Electric Power Company's department responsible for nuclear power plant treatment held a press conference. A manager took out a glass of preliminary purified nuclear wastewater in front of reporters and drank it down without hesitation.

This was in response to the outside world's doubts about nuclear wastewater treatment measures, but the effect was not as good as expected. After the report was published, it attracted ridicule.

People with higher and higher quality education rates know that radiation harms the human body slowly. Unless a huge amount of radiation is received in a short period of time, this little bit of sewage will not prove anything. It may not show up until a few years later.

But Edo Electric Power Company believed its own performance anyway and still insisted that preliminary purification was enough to reduce it to harmless standards.

In the past few days, countries with coastlines throughout East Asia have been protesting fiercely, unanimously opposing the discharge of nuclear sewage into the sea - even after purification.

…

Beijing.

Under the auspices of the Aviation Development Commission, the country's best geological and mining experts were organized here to begin analyzing the Tianmu-2 detection results.

The Tianmu-2 mission arrived at the moon on August 2, landed on August 3, and completed its exploration on August 6 and returned to lunar orbit to dock with the Wutu Space Station. The astronauts there spent another three days sorting out the data and sending it back.

The most important data is the blasting test. This is the first time that humans have conducted such a test. Deng Lei and Li Wei found two most distinctive places and conducted blasting operations at a depth of 10 meters, each blasting out a large crater.

The on-site photos and instrumental surveying and mapping data are very complete and provide very precious original data, which is a treasure for interested experts.

Although it is still far from a rich area of ​​mineral veins, it is enough to analyze a lot of things.

But for Lin Ju, the results of the preliminary analysis were far from ideal.

He directly found Academician She, and several other senior officials of the space agency went abroad with their superiors to visit, and they did not come back for a month.

"Mr. She, I think there is something wrong with the initial progressive blasting plan."

Academician She behaved as expected. The progressive layer-by-layer blasting was the original idea, and it was normal for it to have flaws.

The environment on the moon is completely different from that on the ground, and the Aerospace Development Commission has long been prepared to face various difficulties.

"I haven't read much of the report yet. Can you tell me what's going on?"

Lin Ju sat down and listed the valuable parts separately, and said seriously:

"What we are doing this time is a lunar soil explosion test. The power of the explosion has passed through dozens of meters of lunar soil and reached the broken rock zone below. The thickness of this layer is more than 1,000 meters, which means that the distance between us and the mineral veins The distance is basically a broken rock zone.

According to the data from the detector, this layer is basically formed by the accumulation of various meteorites that were hit by the moon. It contains a lot of metal components and has a high density, which will seriously weaken the power of the blast.

Even though the explosives used this time have been much improved, the effect is only one-third of the expected. Moreover, there is a serious problem that the gravel and lunar soil produced by progressive blasting are too difficult to clean, and we cannot use it like we do on Earth. Hundreds of construction machinery were cleaned.

In the past, we estimated that it would take half a year to complete the mine blasting task, but now this number must be multiplied by at least three. "

Although Academician She had been mentally prepared, this result still gave him a headache. He picked up the information and flipped through it for a while and found that the situation could be even worse.

In the past, many people believed that the low gravity of the moon was an advantage, but now through tests, it seems that it has only a slight positive effect at most, and the actual operation is more troublesome than that of the earth.

He was not an expert in this field, so he could only rub the top of his head and said:

"We have to believe in our experts and talents, we still have half a year to find a solution, and we will always be able to solve it.

There are still many methods other than chemical blasting, but... I am more worried about the cost. According to the statement above, the cost is far less than what we hoped for, and the profit margins we thought before were based on this basis. If you can't make money, it will be difficult to sustain it. "

Lin Ju nodded in agreement. Based on the calculation of a mine depth of 1,400 meters and a bottom diameter of 300 meters, the diameter of the surface mine must be more than 2,500 meters. It would take about 9 billion tons of material to be blown up, which is about 10 billion of the total mass of the moon. one part.

After blowing up these 9 billion tons of material, we can touch the vein layer and start digging. Calculate how many rare earths we have to dig out to recover the cost.

Seeing that Lin Ju had no intention of leaving, Academician She knew that he might have some ideas, so he asked:

"You're not just here to complain, right? What new ideas does Xinyuan have?"

Lin Ju hesitated for a moment, and finally said it boldly:

"Mr. She, do you think we can apply for a few gigaton hydrogen bombs?"

Academician She: "..."

Hydrogen bomb mining - in fact, the base has already had this idea, but it has been hiding it until the specific data of Tianmu-2 was ready to be proposed.

As early as when the metallurgical plan of the base was being discussed, the senior management made calculations. Mining by traditional means would definitely be a huge and extremely expensive project, and the effort would be completely out of proportion to the investment. Therefore, it was natural for someone to propose using the explosion of a nuclear bomb to replace blasting and excavation. .

Not to mention, the base knows a lot about nuclear bombs.

Traditional atomic bombs are technically relatively simple, and Qingshan Base is fully qualified to build one. Cheng Nankai easily took out a simulated explosion model of the atomic bomb and used supercomputing to calculate the explosion effects.

Although he didn't understand the hydrogen bomb, Ye Changsi knew that he was a core member who participated in the entire process of developing the first hydrogen bomb. Although he still hid the secret of the hydrogen bomb in his stomach, he also used the explosive power of the hydrogen bomb with different equivalents. calculate.

The final research result of the base is: if atomic bombs are used, about 200 to 250 medium and large atomic bombs with an equivalent of 150,000 to 200,000 tons are needed; if a hydrogen bomb is used, the optimal model is 10 to 12 giant hydrogen bombs with an equivalent of more than 15 million tons. Or 50 high-yield hydrogen bombs with a yield of 3 million to 5 million tons.

Cheng Nankai calculated that the cost of using an atomic bomb is 750 to 1 billion yuan. This is an estimate based on the base's own production costs. The cost of one bomb is about 3 to 5 million yuan.

Ye Changsi has a say in the hydrogen bomb. He believes that the third-generation hydrogen bomb is a small weapon with extremely high militarization purposes. The detonator is very expensive. The first-generation hydrogen bomb is too large and wastes materials. The most suitable is the second-generation hydrogen bomb. , that is, a medium-sized hydrogen bomb that uses a small atomic bomb as a trigger.

If it is a 15-million-ton equivalent, the cost is about 20 million, and a 3- or 5-million-ton equivalent is around 10 million, and the total cost is only a few hundred million yuan.
