Embodiment 1

[0092] Please refer to figure 2 , the embodiment of the present invention provides a nuclear power plant waste solidification treatment system, comprising: a waste collection unit 1, a waste volume metering unit 2, a waste delivery pipeline 3 connecting the waste collection unit 1 and the waste volume metering unit 2, arranged at the waste delivery A valve assembly 4 on the pipeline 3, a control unit 5 connected to the waste volume metering unit 2 and the valve assembly 4, and a waste solidification unit 6 connected to the waste volume metering unit 2;

[0093] Waste collection unit 1, used to collect and temporarily store nuclear power plant waste;

[0094] The waste volume measuring unit 2 is used to obtain nuclear power plant waste from the waste collection unit 1 through the waste conveying pipeline 3, and measure the volume of the obtained nuclear power plant waste to obtain the waste volume;

[0095] The control unit 5 is used to obtain the waste volume from the waste ...

Embodiment 2

[0188] Based on the same inventive concept, please refer to Figure 9 , the embodiment of the present invention also provides a nuclear power plant waste solidification treatment method, which is applied to the nuclear power plant waste solidification treatment system as described in the first embodiment above. The treatment method includes the steps of:

[0189] S1. Collect and temporarily store nuclear power plant waste through the waste collection unit 1;

[0190] S2. Obtain nuclear power plant waste from the waste collection unit 1 through the waste volume measurement unit 2, and measure the volume of the acquired nuclear power plant waste to obtain the waste volume;

[0191] S3. The waste volume is obtained from the waste volume metering unit 2 by the control unit 5, and the valve switch state of the valve assembly 4 is controlled and adjusted based on the waste volume, so that the valve assembly 4 controls when the valve switch state changes. The amount of waste from th...

Abstract

The invention discloses a nuclear power plant waste solidification treatment system and a treatment method. According to prior arts, a weight metering method is adopted, system equipment complication is high, mounting difficulty is high, debugging, operation and maintenance are difficult, and a weighing unit has risks of weight deviation and measurement failure. With the system and method provided by the invention, the above technical problems are solved. The system comprises a waste collection unit (1), a waste volume metering unit (2), a waste delivery pipe (3), a valve assembly (4), a control unit (5) and a waste solidification unit (6). The control unit (5) acquires waste volume from the waste volume metering unit (2), and controls the open/close state of the valve of the valve assembly (4) based on the waste volume, such that the waste volume metering unit (2) acquires and temporarily stores a preset volume of nuclear plant waste for solidification during each waste solidification link. Therefore, waste precise metering and solidification under a measurement mode with no weighing unit is realized.

Description

technical field [0001] The invention relates to the technical field of nuclear power plant low-radioactive waste treatment, in particular to a nuclear power plant waste solidification treatment system and method. Background technique [0002] The solid waste treatment system is mainly used to deal with low and medium radioactive solid waste generated during the operation and overhaul of nuclear power plants. Among them, the cement solidification and fixation technology was developed the earliest, and has a history of more than 50 years, and the existing nuclear power plants use the cement solidification process to treat low- and medium-level solid waste. [0003] At present, the cement curing system mostly adopts the mixing process in a bucket. The core is to complete the measurement according to the ratio of each material (including concentrate, waste resin and other wastes, cement, and other additives) in the cement curing formula, and to complete each measurement after th...
