As in N, the amount of jet flow in the large flow pipe 26 that flows around the notch 41 and flows toward the jet direction of the small flow pipe 27 increases. As a result, the collision jet between the jet of the large flow pipe 26 and the jet of the small flow pipe 27 tends to form a clockwise vortex as shown by the arrow P. Conversely, if the size of the notch 41 is increased as shown by the alternate long and short dash line M in Fig. 6, the jet flow rate of the large flow pipe 26 that flows around the notch 41 and flows toward the jet direction of the small flow rate 27 is descend. As a result, the collision jet of the jet of the large flow pipe 26 and the jet of the small flow pipe 27 is likely to form a counterclockwise vortex as indicated by the arrow O.

- the protrusion 51 in the illustrated example has a flat plate shape.
- the protrusion amount of the protrusion 51 is increased, the amount of jet flow in the large flow pipe 26 that flows around the protrusion 51 as shown by the arrow Q and flows toward the jet direction of the small flow pipe 27 increases. As a result, the collision jet of the jet of the large flow pipe 26 and the jet of the small flow pipe 27 tends to form a clockwise vortex as indicated by the arrow P. On the contrary, when the protrusion amount of the protrusion 51 is reduced, the jet flow rate of the large flow pipe 26 that flows around the protrusion 51 and flows toward the jet direction of the small flow rate 27 decreases. As a result, the collision jet of the jet of the large flow pipe 26 and the jet of the small flow pipe 27 is likely to form a counterclockwise vortex as indicated by the arrow O.
- the collision jet can be controlled by the amount of protrusion 51. Obedience Thus, if the protrusion amount of the protrusion 51 is adjusted to an appropriate size, the collision jet can be directed to the outlet 29 as indicated by the arrow C, and can be moved straight.
- the protrusion formed in the connecting portion 34 is not necessarily limited to a protrusion that protrudes straight along the jet flow direction (the tangential direction) of the small flow pipe 27 as in the protrusion 51, for example, the jet flow It may be a flat plate inclined with respect to the direction, a bent plate, a bent plate, etc., or even a plate-like one (for example, a horizontal section having a triangular shape may be used). ).
- the piping, etc. breaks and coolant flows out of the system from the location of the break (ie, a primary coolant loss accident occurs), and the pressure in the primary cooling system
- the pressure in the primary cooling system When the pressure decreases and becomes lower than the pressure in the accumulator water injection tank 21, the stored water 22 in the accumulator water injection tank 21 is injected into the reactor vessel from the primary cooling system pipe through the check valve. Is flooded again.
- the flow rate of water injection into the reactor vessel is statically switched from a large flow rate to a small flow rate by the action of the flow damper 24.
- the flow damper 24 collides with the jet of the large flow pipe 26 and the jet of the small flow pipe 27 that flowed into the vortex chamber 25 at the time of the large flow quantity.
- Jet 1S Collision jet control means (notch 41, protrusion 51) that controls to move straight to outlet 29 without forming vortex in vortex chamber 25, small flow pipe 27 (inner surface 27c) and vortex chamber (inner surface) 25a) is provided in the connecting portion 34, and therefore, the control amount of the impinging jet flow by the impinging jet control means that immediately recreates the entire flow damper 24 is adjusted (that is, a vortex).
- the jet flow in the large flow pipe 26 and the jet flow in the small flow pipe 27 cancel each other's angular momentum at high flow rates easily and reliably. Can be prevented. Therefore, the labor and production costs for adjusting the collision jet can be greatly reduced.
- a notch 41 or a protrusion 51 is formed as a collision jet control means, and the collision jet is controlled by the notch 41 or the protrusion 51. Therefore, it is possible to obtain the above-mentioned large effect by a very simple adjustment operation only by adjusting the size of the notches 41 or the amount of the protrusion 51.
- the force that controls the collision jet by the notch and whether the collision jet is controlled by the protrusion are determined by the angle ⁇ of the large flow pipe 26 and the small flow pipe 27 and the flow rate (flow velocity of the large flow pipe 26 and the small flow pipe 27) )) (That is, according to the balance of the angular momentum of the jet of the large flow pipe 26 and the jet of the small flow pipe 27).
- the present invention relates to a pressure accumulation water tank, and is useful when applied to, for example, a pressure accumulation water tank of a reactor emergency water injection device of a PWR power plant.
