After Tu Jianfeng and the others shook hands with Yang Jie and greeted each other, everyone sat down.

"Dean Bai, you can report to the chief. ”

Tu Jianfeng said to Bai Jili.

Bai Jili nodded, and then spoke: " Chief Li, four years ago, our Institute of Atomic Energy Science and Technology wrote a report to the central government, and the content of the report wrote about the problem of insufficient nuclear waste disposal capacity in our country; although the central government also proposed to build four nuclear waste treatment and burial sites, the local government was very resistant to this high-level radioactive nuclear waste and resolutely did not want to dispose of it, and now we have only built two nuclear waste disposal sites, a 50-ton treatment plant in Ganning to deal with weapons-grade nuclear waste, but this treatment plant does not accept nuclear waste from domestic nuclear power plants, and the other is a disposal site in Lingnan Province, but this disposal site can only handle medium and low radioactive nuclear waste, highly radioactive waste cannot be treated. ”

There is also a disposal site under construction in the Xichuan area, but the local government says it will only accept nuclear waste from its own province. ”

Hearing this, Li Kaiyuan's brows were also tightly locked.

"Due to the insufficient processing capacity of the non-treatment plant, the spent fuel of our domestic commercial nuclear power plants can only be stored in boric acid pools, and the design capacity of the pools of general nuclear power plants can only meet the total amount of spent fuel for 15 to 20 years. Since the Castle Peak Nuclear Power Plant was put into operation in 1991, there are currently many nuclear power plant pools full. The nuclear power plant has had to expand more pools, but these are expedient measures, and we have in front of us that hundreds of tons of nuclear waste per year can only be stored in the pools. ”

Tu Jianfeng said at this time: "Chief, our nuclear industry group company is building a spent fuel processing plant for power reactors in Ganning, which is expected to be completed and commissioned in two years, but the capacity to process spent fuel is insufficient, and it can only process 50 tons. ”

"This is mainly due to the fact that our current domestic reprocessing industry has not yet formed industrial production capacity, which is a weak link in the nuclear fuel cycle, and the country has not established a spent fuel reserve system in this regard, and the nuclear industry corporation now has no spent fuel reserve for use. ”

"The budget cost of building a 200-ton nuclear waste treatment plant is more than 10 billion yuan, and it needs to provide special equipment and technology in this area in China to do it, and our nuclear engineering group company really can't afford it by itself. ”

Tu Jianfeng said.

Yang Jie also smiled in his heart when he heard Tu Jianfeng's words, in fact, the main reason why the Nuclear Industry Group Corporation proposed to the central government to embark on a nuclear waste recycling project a few years ago was because the price of uranium raw materials had risen sharply, and there were not enough uranium raw materials in the world.

Rabbit's domestic uranium ore itself is insufficient, almost ninety percent of uranium raw materials are imported from Australia, Hansenkistan, Wenzbikstan, Hamilbia four countries, uranium raw materials are very vulnerable to fluctuations in the international market.

Gallic chickens are currently the best at the technical aspects of secondary uranium recovered from recycling, and have been successful in commercial spent fuel reprocessing plants, which are concentrated at the Ag reprocessing centre, which has become the world's largest LWR spent fuel reprocessing centre.

However, in order to build this treatment center, it took more than 60 billion yuan to build two treatment plants that can process thousands of tons of nuclear waste and commercialize them.

The two treatment plants mainly extract and acclimatize from spent fuel rods, using 95%~96% uranium and about 1% plutonium, and send them to the plant to re-produce nuclear fuel rods - a mixture of plutonium and used uranium.

There are now 22 reactors in the Gallic Chicken nuclear power plant, which is more than a third of all nuclear power plants.

The remaining waste can account for 3%~4%, which will be melted into the glass and waiting for final storage.

However, this recycled secondary fuel is still much more expensive than the fresh uranium currently on the market, which is also where the nuclear industry group hesitates.

At present, there are many nuclear power plant projects in China that are ready to be launched, and when the nuclear power plant is designed and operated, sufficient waste temporary storage ponds have been prepared, but in fact, the problem of dealing with nuclear waste is not so urgent.

At this stage, only a few countries, the Gallic Chicken, John Bull and Big Hair, and the Neon Country, have embarked on the path of "spent fuel recovery and recycling" in the last century, and other countries are still on the sidelines.

This mainly involves factors such as economic benefits, safety risks, and technology maturity, and the nuclear industry group is not particularly concerned about this "spent fuel recovery and recycling" technology.

The main reason for this is that nuclear power accounts for a large part of their country's energy, and the nuclear power group has the financial strength to build large-scale treatment plants, and through these two treatment plants, the nuclear waste treatment plants in other countries have adopted a cost-plus-20% profit scheme, and achieved profitability.

In addition, before the construction of these two treatment plants, the customer signed a service contract with a major foreign customer to pay for the construction and operation of the plant in advance, and the commercial method was very slippery.

However, the domestic nuclear power group companies do not have this economic strength, and the nuclear power projects have not yet been exported, and the domestic nuclear power plant projects have also occupied a large part of the power market share due to the rapid expansion of fuel cell power plants, and all localities are not very happy to launch nuclear power projects.

The other is that the third-generation nuclear power technology of the nuclear power group company has not yet been fully mastered, and the nuclear waste recovery technology can only be better if it is applied to the fourth-generation nuclear reactor.

Li Kaiyuan opened his mouth and asked: "Isn't the Institute of Atomic Energy Science and Technology developing the technology of accelerator-driven spent fuel regeneration cycle system, and how is it going now?"

"Our research institute is now conducting critical experiments on the Qixing-1 zero-power device, and has achieved a lot of scientific research results. ”

Bai Jili also gave Li Kaiyuan a detailed introduction to the situation of this Qixing-1 zero-power experimental device.

"At present, this system is mainly in basic research, and we still have a lot of technical difficulties to do in the technology of proton proton linear accelerator, liquid metal spallation target, and reactor materials......

Bai Jili said with some shame.

"How long will it take for this technology to become commercialized?"

Li Kaiyuan asked.

"This ......"

Bai Jili's lips pursed a few times, and he looked at Tu Jianfeng on the side.

Tu Jianfeng was about to speak, but Li Kaiyuan spoke at this time: "This time I called everyone over just to ask you what difficulties you have in this set of techniques, and you don't have any psychological burden, just say what difficulties you have." ”
