|Title:||ULTIMATE HEAT SINK SYSTEM UTILIZED IN NUCLEAR POWER PLANT|
An ultimate heat sink system utilized in a nuclear power plant comprises at least one non-safe series used by a non-safe user (200), and at least one safe series (A, B) used by a safe user (100, 110, 120). The non-safe series and the safe series (A, B) comprise water cooling systems and water supply systems. Each of the water supply systems comprises a cooling pump set (500, 510) and a heat exchange set (400, 410). The water supply system in each series comprises a set of a cooling pool (700, 710) and a cooling tower (600, 610). The cooling pool (700, 710) is located at the upstream of the cooling pump set (500, 510), and the cooling pump set (500, 510) is connected to a water outlet of the heat exchange set (400, 410) and the cooling pool (700, 710), respectively. A water supply pool (800) communicating with an external water area is provided at the upstream of the cooling pool (700, 710). The cooling pool (700, 710) of each series communicates with a respective water supply pool (800). The ultimate heat sink system provides a highly reliable water source to a power plant, employs the atmosphere as the ultimate heat sink to maximally reduce the impact of an external hydrological and meteorological condition change, thereby achieving goals of a strong capability of resisting an external extreme condition, a simple system configuration, and low operation and maintenance costs.
