[0018] Example
[0019] Such as figure 1 As shown, the continuous monitoring system for the state of the spent fuel pool includes a mounting bracket 3 fixedly connected to the side wall of the spent fuel pool 1. A guide tube 4 is vertically arranged on the mounting bracket 3, and the length of the guide tube 4 covers at least the top of the fuel grid 2. The height range to the full water level of the pool. The continuous liquid level sensor 5 with a length of about 9m is suspended and installed in the guide tube 4. The RTD temperature sensor is installed at the bottom of the guide tube 4, and the lower end of the guide tube is open. The water in the pool enters the guide tube from the lower end of the guide tube. The embedded part of the side wall of the spent tank is fixed to the mounting bracket 3 by welding, and the top of the continuous liquid level sensor 5 is fixed to the first mounting plate of the mounting bracket 3 through a flange, and can be drawn out from the guide cy...
