う問題点がある。Additionally, nuclear power plants have fuel pools installed to store spent fuel, etc., but because the water in the pool has a large free liquid level, large fluctuations in the liquid level are excited during an earthquake. there is a possibility. In particular, the water in pools contains radioactive materials, making overflowing extremely dangerous. A method of installing baffle plates on the side walls of the pool has been devised as a method for suppressing this liquid level fluctuation, but this method has the problem of requiring a large space.

収納することができることを特徴とする。(Summary of the Invention) The spent fuel pool of the present invention develops a flexible sheet supported by a guide on the side wall near the water surface, so that it becomes a resistor against the flow of the stored liquid when the liquid level fluctuates. Another feature is that the flexible sheet can be easily stored along the guide during fuel operation.

できる。According to the device of the present invention, by deploying the flexible sheet, it is possible to provide resistance to and suppress the flow of the stored liquid due to the fluctuation of the liquid level that occurs during an earthquake. Furthermore, if the expansion of the flexible sheet impedes operations within the fuel pool, the restraining member is constituted by the flexible sheet, so it can be easily stored. Therefore, fluctuations in the liquid level can be suppressed without reducing the operability within the fuel pool.

れる。FIG. 1 shows a typical embodiment of the invention. FIG. 2 is an enlarged view of the suppressor. 3 and 4 are enlarged views of the main part guide 5 of the device. Both ends of the flexible sheet 1 are connected and fixed to a support rod 2 and a drive rod 3, and the support rod 2 is fixed near the water surface of the pool side wall 4 or below the water surface. Also, drive rod 3
is inserted into the groove of the guide 5, guided in the front-back direction, and connected to the wire 6. The wire 6 is wound around a manual drum 8 attached to the upper part of the pool side wall 4, passes through rollers 7, and is again connected to the opposite side of the drive rod 3. The flexible sheet 1 is expanded or closed by rotating a manual drum 8 and moving a drive rod 3 connected to a wire 6 back and forth.

収納することができる。FIG. 5 shows this operating situation. By rotating the manual drum 8 and pulling out the drive rod 3 forward, the flexible sheet is unfolded during normal times or during an earthquake, and becomes a resistor against fluctuations in the liquid level. Further, by installing the device in parts, it is possible to easily store the movable sheet only in the portion that interferes with work by rotating the manual drum 8 during fuel operation, periodic inspection, etc.
