Abstract

The invention discloses a mobile online radioactive decontamination system for a nuclear power plant, which includes a mixing tank, an injection pump, a buffer tank, a decontamination pump and an electric heater. The decontamination system includes at least two movable modules, and each movable module All are equipped with input and output interfaces for connecting with other movable modules or equipment to be decontaminated; mixing tanks, injection pumps, buffer tanks, decontamination pumps and electric heaters are respectively set in the movable modules; when in use, the The movable module is moved to a suitable position, and the movable module and the online equipment to be decontaminated are connected to each other in a predetermined order through the connection interface, so that the liquid in the mixing tank can pass through the pipeline in turn through the injection pump, buffer tank, decontamination pump and electric decontamination pump. After the heater enters the equipment to be decontaminated, the equipment to be decontaminated is decontaminated online. The advantages of the present invention are as follows: the present invention can carry out online decontamination of the equipment to be decontaminated in the nuclear power plant, thereby simplifying the operation, reducing the radiation dose of personnel and reducing the risk of radiation exposure.

Description

technical field [0001] The invention belongs to the field of radioactive decontamination of nuclear power plants, and more specifically, the invention relates to a mobile online radioactive decontamination system of nuclear power plants. Background technique [0002] During the operation of nuclear power plants, radioactive pollution will be generated. Equipment and components contaminated by radioactivity need to be decontaminated before maintenance or inspection to reduce the radiation dose to personnel. Therefore, decontamination is an essential and important link in the operation of nuclear power plants, and it is an effective means to implement the principle of radiation protection optimization and as low as reasonably achievable (ALARA). [0003] During the operation of the nuclear power plant, when it is necessary to overhaul the radioactively contaminated equipment, it is usually removed from the system, sealed and packaged, and transported to the hot machine repair...
