Nuclear energy utilization is very important for our country's national defense construction and sustainable development of energy system, however, the safe disposal and reuse of a large number of depleted uranium produced after nuclear energy utilization is a problem to be solved in pollution prevention and control work. 238 U, which is harmless to human body), in particular, we use U3O8 prepared from depleted UF6 as raw material, and prepare beta-UO3 as catalyst by a simple dissolution and reprecipitation method, and the beta-UO3 is used for catalyzing oxidation of aniline to synthesize 1-oxidized diphenyldiazene or derivatives thereof; the application creates a way for reuse of depleted uranium waste, and on the other hand, aniline and its derivatives can be converted into 1-oxidized diphenyldiazene or derivatives thereof with higher added value, which has extremely important significance from the aspects of environmental friendliness and sustainable development, and from the aspect of synthesizing higher added value products.

The rational use of nuclear energy plays a vital role in the process of consolidating national defense and security and green transformation of energy system in China. However, the proper management and resource utilization of depleted uranium (especially 238 U, which does not pose a direct radiation threat to human body) generated from the application of nuclear energy have become a technical problem to be solved in the field of environmental protection and sustainable development. In particular, we use U3O8 prepared from depleted UF6 as raw material, and use UO4·2H2O prepared by simple dissolution and precipitation as catalyst to prepare 1-oxidized diphenyldiazene or its derivatives by catalytic oxidation of aniline. On the one hand, the invention creates a way to reuse depleted uranium waste, and finds a new way to transform this traditionally regarded as a problem waste, on the other hand, it ingeniously builds a bridge from aniline and its derivatives to high value-added chemicals-1-oxidized diphenyldiazene or its derivatives, which shows extraordinary value in environmental, economic and social benefits. Whether from the perspective of environmental friendliness and sustainable development, or from the perspective of synthesizing higher value-added products, it has extremely important significance.

At present, the world is suffering from air pollution due to thermal power generation, sea level rise due to atmospheric temperature rise, land sinking due to rising of the sea level, and public nuisance due to nuclear power generation, such as spent depleted uranium, plutonium, and.gamma.-ray radioactive materials. In order to solve these problems, inexhaustible visible-light wave power generation of sunlight radiation energy and a Huang Daozhou converter are integrated.SOLUTION: The secondary coil of the ecliptic transformer according to the present invention may be connected to a country having a shortage of electric power at night due to the rotation of the earth and a country having a shortage of electric power due to a large amount of power consumption even in the daytime via the shortest conductor on the same longitude to transmit and receive electric power.SELECTED DRAWING: Figure 1

The wisdom utilization of nuclear energy plays a core and irreplaceable role in consolidating national defense security and transforming energy system to green. While the nuclear energy technology is booming, how to properly manage and efficiently resource the depleted uranium (especially 238 U, although it does not constitute direct radioactive hazard to human body) generated in the process of nuclear energy application has become an urgent and key technical challenge in the field of environmental protection and sustainable development. In particular, we use U3O8 prepared from depleted UF6 as raw material, and use UO4·2H2O prepared by simple dissolution and precipitation as catalyst to catalyze the synthesis of diphenyldiazene or its derivatives from aniline: one aspect of the invention creates a way to reuse depleted uranium waste, finding a new way to transform this traditionally difficult waste, and on the other hand, it ingeniously builds a bridge from aniline and its derivatives to high value-added chemicals-diphenyldiazene or its derivatives. Not only can it effectively reduce the potential threat of depleted uranium waste to the environment, realize the green transformation and resource utilization of waste, but also can promote the chemical industry to a more efficient and environmentally friendly direction, and bring significant economic benefits to the chemical industry.

A method for stabilizing and disposing of depleted uranium hexafluoride (UHF) is disclosed, applied to a UHF stabilization and disposal system. The steps are as follows: 1. Gasification of depleted UHF; 2. Hydrolysis and precipitation reaction; 3. Solid-liquid separation; 4. Post-precipitation treatment; 5. Post-filtrate treatment. The advantages of this invention are that it transforms the difficult-to-store depleted UHF into a stable uranium trioxide (UHMWCO) solid, achieving safe disposal of depleted UHF, reducing the required amount of depleted UHF containers, and lowering container disposal costs.
