The invention relates to the field of auxiliary cooling water systems for nuclear power plants, and discloses an abnormal emergency treatment system and method for a cooling water source of a mega-kilowatt nuclear power plant. The system comprises a water storage tank, an external water source inlet gate, a drainage channel, an external water body outlet gate and a connecting channel, wherein thewater storage tank is provided with a first water inlet end, a second water inlet end and a water outlet end; the external water source inlet gate is arranged at the first water inlet end and is usedfor being connected with an external water source; the water storage tank is connected with a cooling facility through the water outlet end and supplies cooling water to the cooling facility; the water storage tank is connected with one end of the connecting channel through the second water inlet end; the other end of the connecting channel is connected with the drain channel. The abnormal emergency treatment system and method for the cooling water source of the mega-kilowatt nuclear power plant can be used for solving the running problem when the cooling water source of the nuclear power plant is abnormal, prolonging the running time of the unit under the abnormal situation of the external water source, and improving the ability of the nuclear power plant to deal with the abnormal situations of a cooling source.
Description
technical field [0001] The invention relates to the field of auxiliary cooling water systems of nuclear power plants, in particular to an emergency treatment system and method for abnormal cooling water sources of mega-kilowatt nuclear power plants. Background technique [0002] Cooling water sources are critical to the normal operation of nuclear power plants. Most of the existing nuclear power plants are located in areas with sufficient cooling water, such as coastal areas. In areas with sufficient cooling water, the population density is also high, which will produce a large amount of wastewater containing high concentrations of nutrients. These wastewaters containing high concentrations of nutrients are directly or indirectly discharged into the ocean, leading to eutrophication of seawater. [0003] The eutrophication of seawater will produce a series of biological abnormal events, such as the biological events caused by the excessive reproduction of marine organisms s...
