Chapter 216 216 Joining China National Nuclear Corporation (tomorrow change)
216 Joining of CNNC

One stone stirs up waves. Although Wang Feng is continuing his research on thermoelectric semiconductor materials, anyone with a discerning eye can see that his focus of work has not been on it for a long time, but has turned to his new favorite: that is, theory. Physics, or nuclear physics.

This is undoubtedly incomprehensible to everyone. When the news was broadcast on the news, they were simply stunned.While rejoicing, many people were secretly waiting to see his jokes.

And they silently gathered their strength, waiting for Wang Feng to end miserably and pay for his willfulness, and then they could ridicule this ignorant young man in front of the public.

After all, they had been suppressed for too long, but it turned out that Wang Feng had a halo around him, which they could not touch.But now... the heat of the halo is gradually receding, and everyone is slowly returning to the same starting line.

However, while they were waiting to see the good show, they did not expect another big news: the theoretical verification stage of the heavy-duty decay electromagnetic accelerator was successfully completed, and the next stage of the plan will begin.

The moment they heard the news, a thought flashed through everyone's minds: Is this news fake?

After all, although they don't study theoretical physics, everyone still has scientific literacy.The difficulty of influencing microscopic particles at the microscopic scale of atoms, or even below atoms, is simply immeasurable.

If you really want to describe it, it's probably a fantasy. I really didn't expect to pass the verification stage?

All of a sudden, the number of downloads of Wang Feng's online papers surged, not only his online papers, but also the papers of other doctoral students in his research institute began to be circulated frantically.

As we all know, the decay rate of radioactive substances is an attribute of itself, and it is not affected by external factors, whether it is a change in temperature, a change in light conditions, or a catalyst, etc...

But if the content of this paper is true and there is no fake element, it means that this theory has been broken, which is very scary.

Due to the great impact of this paper, not only the editors of the Journal of Physical Review are scratching their heads, but even domestic experts are also very concerned.

I heard that the academicians of the Chinese Academy of Sciences have formed an expert group to evaluate the authenticity of this physical achievement... But it seems that due to some reasons, it has not yet been approved.

As the incident unfolded, the impact of this matter became greater and greater. The first to jump out were those environmental protection organizations in the West. They accused Wang Feng's device of having great hidden dangers, which may cause the spread of radioactive substances, which is harmful to the environment. Causing irreversible damage...

Even some domestic environmental protection organizations, who listened to the wind and rain, began to take organized actions after hearing what foreign counterparts said, but thanks to the good security environment in the country, they have not been able to cause any major damage and damage. Influence.

So they collectively began to call on other people to take action on the Internet to oppose these experiments related to nuclear energy...but they were quickly deleted and banned by their platforms. It is not difficult to see that the pillar industries have great influence. Still very big.

It's just surprising that those public officials and Dawei didn't take advantage of this incident to cause trouble. This is to make the people who eat melons eat a lot less melons.

In fact, the reason is very simple. First of all, those companies with large platforms have a good sense of supervision, and they have warned the traffic artists under them in advance. Naturally, these people dare not do anything for their own jobs.

The second is the remaining small platform companies. Their survival depends on the advertising of those real industries. They dare not offend those companies, and naturally they dare not offend the top technology service companies in the industry.

But the most important thing is that Wang Feng is not just a tech worker, he is also a very, very rich entrepreneur, and more than that, his official relationship is not comparable to them.

So of course they didn't dare to offend each other.

Of course, Wang Feng didn't take them seriously either. Not only did he not get a good rest after that experiment, but he became busier and busier.

Of course, there are his own reasons, he wants to advance the plan faster, but more of it comes from other factors.

First of all, since the word "nuclear" is involved, it is naturally inseparable from dealing with official institutions.

The first to bear the brunt of this is the China National Nuclear Corporation, a giant in the military and energy fields.

CNNC is the pioneer of China's nuclear technology. It has successively created "China's first atomic bomb exploded successfully", "China's first hydrogen bomb exploded successfully", "China's first nuclear submarine successfully launched", "China's first self-designed and built nuclear power plant— — Qinshan Nuclear Power Plant connected to the grid for power generation”

"China's independent intellectual property rights of third-generation nuclear power technology - the construction of the world's first Hualong No. [-] reactor" and "China's first self-developed fast neutron reactor" and many other "new China's first";
Actively expand the application scope of nuclear energy, and independently research and develop multi-purpose modular small reactors (Linglong No. [-]), "Yanlong" pool-type low-temperature heating reactors and other reactor types, as well as China Circulator No. [-] A nuclear fusion research device; A complete nuclear technology and industrial system that only few countries have; it is the main force of China's nuclear energy development and nuclear power construction, and has built five major nuclear power bases in Tianwan, Qinshan, Sanmen, Fuqing and Changjiang from north to south;
It is the only nuclear fuel manufacturer, supplier and service provider in China, and has successfully developed my country's first large-scale commercial pressurized water reactor advanced fuel element CF3, which meets the needs of serialization and patterning of nuclear energy; it is the national team and main force of uranium geological mining and metallurgy Army, built two green mines for in-situ leaching uranium mining, XJ and NMG;

It is the leader of national nuclear engineering construction, engaged in nuclear power construction for more than 30 consecutive years, covering almost all mainstream nuclear power and scientific research reactor types in the world; it is the national team of nuclear environmental protection industry, and has built a large-scale nuclear facility decommissioning and radioactive waste treatment base;
It is the largest nuclear technology application enterprise in China, with 80% of domestic R&D and production capabilities. The supply of nuclear medicine drugs in the Chinese market reaches more than 70%; it is the only enterprise in China that has exported nuclear power plants in batches, exporting 7 nuclear power units to Pakistan. .

China Nuclear Power Holdings, a subsidiary of China National Nuclear Corporation, operates 20 nuclear power units with an installed capacity of 17966 megawatts.Including: my country's first independent design, construction, operation and management of nuclear power plants - Qinshan Nuclear Power Plant, known as "the glory of the country"; my country's first independent design, construction, operation and management of large-scale commercial nuclear power plants - Qinshan Second Nuclear power plant; Qinshan Third Nuclear Power Plant, my country's first heavy water reactor nuclear power plant that has realized nuclear power project management in line with international standards;

my country's most advanced nuclear power plant in service - Jiangsu Tianwan Nuclear Power Plant; the world's first third-generation nuclear power AP1000 - Zhejiang Sanmen Nuclear Power Project; my country's independent third-generation nuclear power Hualong No. [-] demonstration project - Fujian Fuqing Nuclear Power Project; my country's southernmost HAN Provincial Energy Construction Project No. [-]——Hainan Changjiang Nuclear Power Project, etc.

It was relying on the opponent's strong construction ability and excellent design ability that Wang Feng's first experimental machine was released.Without their help, it would have been absolutely not easy for Wang Feng to accomplish these things.

Therefore, courtesy should be reciprocated. Since someone has sent someone here, he has to receive it in person. After all, it is a high-level central enterprise.

Even Wang Feng had to put down what he was doing first and come over to receive this batch of leaders.

"Professor Wang, it's better to see him than to hear about it. What a talent!"

"It's so-so, Manager Yan is fine."

"Okay, okay, let's stop talking about polite words. Anyway, we have met a few times before, so we can be regarded as acquaintances. Professor Wang, you should take me to see your baby."

Hearing this sentence, Wang Feng was obviously taken aback. He hadn't noticed before that this person was actually impatient: "Since you made this request, there is naturally no problem."

Wang Feng naturally understands why the other party is so anxious. The constraints on the development of nuclear power are the constraints on the development of nuclear industry groups. In a way, these two constraints are actually similar.

There should be many headaches for China National Nuclear Corporation, but one of the most troublesome problems should include the disposal of spent fuel.

It is no secret that the issue of nuclear waste is a key constraint on the sustainable development of nuclear energy. A one-million-kW pressurized water reactor (PWR) nuclear power plant discharges about 25 tons of spent fuel every year; it contains about 23.75 tons of recyclable uranium and plutonium. About 200 kg, medium and short-lived fission products (FPs) about 1000 kg; there are also sub-actinides (MAs) about 20 kg, and long-lived fission products (LLFPs) about 30 kg.

What is nuclear waste?Nuclear waste refers to radioactive waste, which is not only produced in nuclear power plants, but also in nuclear fuel production and processing, hospitals, isotope production and other fields.

High-level radioactive waste, also known as spent fuel, mainly comes from the burned nuclear fuel of nuclear power plants;

Low- and medium-level radioactive wastes come from discarded and decommissioned instruments and equipment used in nuclear power plants, wastes generated in the production and processing of nuclear fuel, etc.

The hazard composition level of nuclear waste can be summarized in one sentence, high-level waste, which accounts for 3% of the total, contributes 95% of the radioactivity.So it can be said that it is not required to dispose of all nuclear waste, as long as the 3% of high-level radioactive waste can be disposed of, it is almost equivalent to removing the curse on the head for the development of nuclear energy.

The total amount of high-level radioactive waste is very small, but it is very harmful. The nuclear waste we usually talk about mainly refers to this type of waste.The reason why spent fuel is so harmful is that it contains highly radioactive elements that are extremely harmful to the human body.

核燃料在堆内经过中子轰击发生核反应后，燃耗深度达到卸料标准的燃料组件从堆内卸除，即为乏燃料。乏燃料中含有含有大量未用完的可增值材料238U或232Th，未烧完的和新生成的易裂变材料Pu239、U235或U233以及核燃料在辐照过程中产生的Np、Am、Cm等超铀元素，以及裂变元素Sr90、Cs137、Tc99等。

These things are very harmful to the human body, especially to the genes of the human body.It's okay for adults, but for children and teenagers, if they are exposed to excessive radiation during their growth, they are very prone to some stubborn diseases that are difficult to cure, similar to congenital diseases.

If it is for pregnant women, it will almost [-]% cause fetal deformities or congenital diseases, and the harm is so great that it makes people look pale.

However, for such harmful things, we have no good way to deal with them so far.

At present, the treatment of high-level nuclear waste by major nuclear industrial countries in the world is mainly divided into two routes: closed fuel cycle and open fuel cycle (also known as one-pass long-term disposal).

The depth of boreholes for deep geological storage of spent fuel is generally 3 to 5 kilometers below the ground. Due to the self-sealing of boreholes, the reversibility of spent fuel is very small.

The selection of deep burial sites in the United States is based on volcanic tuff.There are currently about 7 tons of spent fuel in the United States, stored in 72 commercial nuclear power plants.In addition, 2000 to 2400 tons of spent fuel are added each year.At present, three-quarters of the spent fuel is stored in the spent fuel pool in the reactor, and the rest is stored by dry method after spent fuel reprocessing; dry storage technology has become mature in the United States.

Sweden is based on granite, but the country's radioactive waste disposal agency designed a 5cm-thick copper-covered shielding tank that it believes will not corrode for 100 million years, surrounded by a thick layer of bentonite.

So the way of open treatment is to simply dig out the nuclear waste, and then bury it in a bottomless place.

The latter is another treatment method. The spent fuel treatment at the Rokkasho reprocessing plant in Japan and the Hague reprocessing plant in France is mainly based on the PUREX process.

Spent fuel is cut up, dissolved in some solvents, and then subjected to two rounds of extraction. In the first extraction cycle, extraction is performed using geometrically safe pulsed extraction columns and mixer-settlers. This cycle will separate most of the Fission products, uranium and plutonium.

In the open cycle, the hydrological requirements of the spent fuel deep burial site are extremely high, and there are uncertainties and site limitations.The Purex process is not only the process used in the reprocessing of light water reactor fuel, but also is being developed for the reprocessing of fast neutron breeder oxide fuel. The reprocessing plants in France and Japan are in operation, and the uranium and plutonium recovered in the process are returned to recycled in the reactor.This process has become the only one in practice in modern reprocessing plants.

Of course, this is just a compromise. In the final analysis, we still have no way to deal with the hidden danger, completely solve it, and can only keep it.

From the initial stage of the development of nuclear fission power generation technology to the present, spent fuel reprocessing has been the main foothold for a large number of so-called green environmentalists to attack nuclear power.

It is foreseeable that if this matter can really be solved, then they will usher in a peak period of development. After such a round of development, their ranking among central enterprises may not be able to move forward. .

Therefore, the reason why manager Yan is so anxious is not necessarily because of his quick temper, but because of the benefits that move people's hearts.

　Yesterday, I notified Unity temporarily. The manager seemed to be out of love. He kept pouring us alcohol. It was broken!
