Description

Application method of automatic feeding assembly of uranium conversion material
Technical Field
The invention relates to the technical field of relevant uranium conversion equipment, in particular to an application method of an automatic feeding assembly of uranium conversion materials.
Background
At present, China is adjusting the medium-long term development planning of nuclear power, strengthening the development of coastal nuclear power and scientifically planning the nuclear power construction in inland areas. With the rapid development of nuclear power, the installed capacity is rapidly increased, and higher requirements are provided for the supply of nuclear fuel.
The uranium ore is a main raw material for preparing nuclear fuel, and the whole preparation flow from the uranium ore to the nuclear fuel can be subjected to two steps of uranium purification and uranium conversion in sequence. Uranium purification refers to the conversion of uranium ore concentrates to refined UO2The production process of (1). Uranium conversion refers to conversion from refined UO2To UF6The production process of (1).
UO produced in uranium purification step2The powder material is stored in a special sealed container for standby. The sealed container is provided with a discharge hole which can be closed or opened at the lower end, and the capacity and the volume are designed to be smaller so as to be convenient for transportation or storage. When going to the uranium conversion step, it is necessary to seal the UO in the multi-tank vessel2The powder is discharged into a transfer silo, an operation known as UO2And (5) feeding operation.
In the current industry, UO2The feeding operation is carried out in the three-layer factory building. One floor of factory building is stored with a plurality of tanks filled with UO2The sealed container of powder material and the second floor of the factory building are provided with hydrofluorination equipment (used for processing UO) which is communicated in sequence2) And a transfer bin, wherein a discharge port communicated with the transfer bin is arranged at the third floor of the plant, and the discharge port is used for receiving UO poured out from the sealed container2And (3) powder material. Executing UO2When the material feeding operation is carried out, a plurality of cans of sealed containers need to be driven by a manually operated travelling craneThe sealed containers are butted with the discharge openings one by one and then poured.
The above-mentioned UO2The feeding operation has the following disadvantages:
1. the sealed container is manually lifted from the first floor of the factory building to the third floor of the factory building, and after the materials are butted and poured, the empty sealed container needs to be manually lifted back to the first floor of the factory building. The operation of up-and-down reciprocating lifting is time-consuming and labor-consuming, and the labor intensity of workers is high.
2. The upper layer of the factory building is always required to be equipped with operators, and the operators are responsible for opening or closing the discharge hole at the lower end of the sealed container when the sealed container is in butt joint with the discharge hole. When the material is poured, the control screw rod is manually screwed to open the discharge hole at the lower end of the sealed container, and after the material is poured, the control screw rod is manually screwed to close the discharge hole at the lower end of the sealed container. The operation of manually opening and closing the sealed container wastes time and labor, and the manual labor intensity is high.
3. When the butt joint and the material pouring are carried out on the upper layer of a factory building, the UO2The powder material is easy to leak out from the contact surface between the discharge port of the sealed container and the discharge port of the third building of the factory building, and generates dust and UO2Has radioactivity, and directly harms the health of operators in the third floor of the factory building.
4. On the one hand, to avoid UO2The powder material is diffused to the outside of the factory building to pollute the environment, the factory building is isolated from the outside, and on the other hand, the second floor of the factory building is provided with hydrofluorination equipment, the operation temperature of the hydrofluorination equipment is very high, and the two aspects jointly cause the higher environment temperature in the factory building. In hot summer, the indoor temperature of the third building of the factory building is as high as 50-60 ℃, and the working environment of operators positioned in the third building of the factory building is very severe.
Based on the defects, a set of the catalyst is designed for UO2However, in the automatic feeding system, how to realize unattended automatic continuous feeding operation in the third floor of the factory building and realize automatic return of original paths of all empty tank containers after feeding is completed is the design difficulty of the whole automatic feeding system.
