Problems solved by technology

When transporting the feed liquid containing solid particles produced in the reprocessing process of spent fuel, since the feed liquid contains solid particles, the conveying distance is relatively long. In order to prevent the accumulation of sediment, it is required to meet certain conveying speed and pressure requirements. , air lifter and other maintenance-free radioactive material liquid delivery methods are not suitable for the delivery of material liquid containing solid particles

Abstract

The invention discloses a radioactive material liquid conveying device and system. The device comprises an isolation chamber, a first container, a second container, an air inlet pipeline, an exhalation pipeline, a vacuum pipeline and a material liquid conveying pipeline, wherein a first valve is arranged on the air inlet pipeline, and a second valve is arranged on the exhalation pipeline; a thirdvalve is arranged on the vacuum pipeline, and a fourth valve is arranged on the material liquid conveying pipeline; and one or more of the first valve, the second valve, the third valve and the fourthvalve are ground penetrating valves, and each ground penetrating valve penetrates through the cavity wall of the isolation chamber. Each ground penetrating valve comprises a valve element and a driving assembly arranged on the valve element, wherein the driving assembly is used for controlling the on-off state of the valve element, and the driving assembly is arranged outside the isolation chamber. By means of the conveying mode of combining a compressed air source with vacuum radioactive material liquid suction, the radioactive material liquid containing solid particles can be conveyed, andlong-distance conveying can be achieved, so that the driving force of the compressed air source needed during conveying is reduced, the requirement for the pressure bearing limit on the container is reduced, the safety of the conveying mode is high, and conveying is complete.

Description

technical field [0001] The invention belongs to the technical field of nuclear fuel reprocessing, and in particular relates to a radioactive material liquid delivery device and system. Background technique [0002] In the process of PUREX water process for nuclear power plant spent fuel, radioactive fluid transportation occupies an important position in the reprocessing process. The main transportation methods include self-flow, steam jet pump, air lifter, mechanical pump, vacuum siphon transportation, etc. . When the reprocessing plant maintains the fluid conveying device, if the conveying device is exposed to radioactive substances, necessary biological shielding must be provided for the maintenance personnel and measures to prevent the spread of contamination must be taken during maintenance. Delivery method for repairs. When transporting the feed liquid containing solid particles produced in the reprocessing process of spent fuel, since the feed liquid contains solid p...
