Problems solved by technology

[0002] For the fuel pool, which includes components such as spent fuel elements, targets, and beryllium blocks temporarily stored in the reactor, after years of deposition, a large amount of sediment and attachments have accumulated on the spent fuel storage racks and the bottom of the pool, seriously affecting water quality of the fuel pool
These deposits and attachments cannot be completely removed by running the purification system and changing the water, and the fuel pool is highly radioactive, cleaning by this method will produce a large amount of radioactive waste resin

Embodiment 1

[0021] see Figure 1-2 , the fuel pool cleaning device 100 shown in the preferred embodiment of the present invention includes a positioning system 10 , a cleaning system 20 , a filtering system 30 , a collecting system 40 and an electrical control system 50 .

[0022] The positioning system 10 positions the cleaning system 20 to the position in the fuel pool that needs to be cleaned. The positioning system 10 is arranged above the pool surface of the fuel pool and fixedly connected with the pool wall of the fuel pool. The positioning system 10 includes an X-axis positioning component 11 and a Y-axis positioning component 12 . The X axis in the present invention refers to such as figure 1 The direction shown is parallel to the wall of the fuel pool, and the Y axis refers to figure 1 The direction shown is parallel to the pool surface of the fuel pool and perpendicular to the X-axis.

[0023] The X-axis positioning assembly 11 includes a guide rail 111 , a sliding piece 112...

Abstract

The invention discloses a fuel pool cleaning device which comprises a positioning system, a cleaning system and a filtration system, wherein the positioning system is used for positioning the cleaning system in the fuel pool, and the cleaning system comprises a cleaning machine, a suction tube, a cleaning pipe and a nozzle. One end of the suction tube extends into the fuel pool, and the other end communicates with the cleaning machine. One end of the cleaning pipe communicates with the cleaning machine, and the other end extends into the lower portion of the fuel pool and communicates with the nozzle. The filtration system comprises a dirty sucking cover, a filter and a discharging pipe discharging filtered fluid into the fuel pool, the dirty sucking cover communicates with the discharging pipe through the filter, and the dirty sucking cover is arranged on the reflection direction of water columns sprayed out of the nozzle. The fuel pool cleaning device collects slag and removes dirt, and refuses can be compressed and collected. No extra waste liquid is generated, which is safe and environmental friendly.

Description

technical field [0001] The invention relates to a cleaning device, in particular to a fuel pool cleaning device. Background technique [0002] For the fuel pool, which includes components such as spent fuel elements, targets, and beryllium blocks temporarily stored in the reactor, after years of deposition, a large amount of sediment and attachments have accumulated on the spent fuel storage racks and the bottom of the pool, seriously affecting The water quality of the fuel pool has been improved. These deposits and attachments cannot be completely removed by running the purification system and changing the water, and the fuel pool is highly radioactive, cleaning by this method will produce a large amount of radioactive waste resin. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fuel pool cleaning device that does not produce radioactive waste resin. [0004] The technical solution adopted by the present inv...
