Since the fuel tank 1 having the structure and function described above is generally installed in the upper part of the reactor building, it has a structure that is easily affected by an earthquake. FIG. 3 is a schematic sectional view showing a situation in which pool water 2 shakes due to an earthquake and flows out of a fuel exchange floor 61 in a conventional fuel pool 1. Third
As shown in the figure, if an earthquake with large seismic acceleration occurs, the pool water 2 will oscillate and spill out from the refueling floor 61, requiring workers to clean it. There was a possibility that a situation that was not in line with the safety design, such as worker exposure to radiation, could occur. Since the fuel pool is an extremely important facility for safety, there has been a demand for a structure that can function satisfactorily against anticipated earthquakes, especially from the standpoint of seismic design.

A second embodiment of the present invention will be described below with reference to FIGS. 8 and 9. In FIG. 8, the same reference numerals are given to the parts of the present invention, and the explanation of the structure thereof will be omitted. In FIG. 8, a water control plate 31 is hinged to the water control plate mounting portion 19 so as to be freely rotatable in the vertical direction, and an oval hole 32 is bored in the water control plate 31. In addition, a water control plate support member 33 is hinged to the water control plate support member mounting portion 20 so as to be rotatable in the left and right direction, and one end of the water control plate support member 33 is attached to a water control plate fixing bin (hereinafter referred to as a fixed pin). A bottle) 34 is attached. This fixed bin 3
4 has the structure shown in Fig. 9, and this Fig. 9(a)
9 is a vertical sectional view of the tip of the water control plate support member showing the identification bin 34 of FIG. 8, and FIG. 9(b) is a sectional view taken along the line A-A of FIG. 9(a'). As shown in FIG. 9, a hole 36 is formed at the tip of the water control plate support member 33, and a convex portion 37 is provided at the middle portion of the inner surface of this hole 36. On the lower surface of this convex portion 37, a ninth hole is formed along the inner circumference of the hole 36.
A slightly downward slope is provided at a protrusion 38 indicated by a broken line in the figure, and the mechanism is such that it is tightened when the fixing pin is rotated. This mechanism supports the water control plate 31 and the water control plate by the friction force between the water control plate fixing pin lower part 39 and the convex portion 37 and the friction force 1 between the water control plate fixing pin head 40 and the water control plate 31. The parts are fixed. A fixing pin pressing plate 42 is installed at the bottom of the tip 35 of the water control plate support member 33 via a spring 41, and the reaction force of this spring 41 prevents the fixing pin 34 from rotating and loosening. It is prevented. The oval hole 32 is bored in the water control plate 31 so that the water control plate fixing bottle head 40 and lower part 39 can pass therethrough.
