Further, seawater is taken in by a seawater pump and supplied to a reactor auxiliary equipment cooling water cooler in the reactor room, thereby cooling the cooling water (primary coolant) discharged from the containment vessel.
In the case of a water intake facility of a nuclear power plant, it is important to always ensure a sufficient amount of cooling water, and a prescribed water level of a water intake path must be maintained. However, when tsunami occurs, the water level in the water intake path may decrease due to ebb of tide. In the case of tsunami, the sea bottom becomes shallow as approaching the coast from the sea, and the wave height becomes high, reaching several times the sea height on the coast line. Then, the landing tsunami continues to return to the valley of the sea to come again after the sea is rushed in with a large water pressure. In this case, the water level of the cooling water (seawater) in the water intake path is lowered due to the ebb of the tide, and the various pumps cannot take the cooling water, and air vortex may be generated and damaged.
Therefore, a system is required to be designed to monitor the water intake of the nuclear power plant, so as to ensure the safety of the production process.
