The invention provides a nuclear power station secondary side emergency water supply system and a nuclear power station. The nuclear power station secondary side emergency water supply system comprises a steam-driven water supply pipeline and an electric water supply pipeline. The steam-driven water supply pipeline comprises a first water supply tank, a steam-driven pump and a first regulating valve in sequence in the direction from the first end to the second end of the steam-driven water supply pipeline. The first end of the steam-driven water supply pipeline is communicated with the first water supply tank, and the second end of the steam-driven water supply pipeline is communicated with the first steam generator of the nuclear power station; and in the direction from the first end to the second end of the electric water supply pipeline, the electric water supply pipeline sequentially comprises a second water supply tank, an electric pump and a second regulating valve. The first endof the electric water supply pipeline communicates with the second water supply tank, and the second end of the electric water supply pipeline communicates with a second steam generator. The nuclearpower station secondary side emergency water supply system is relatively high in equipment utilization rate, low in cost and relatively good in reliability.
Description
technical field [0001] The invention relates to the technical field of nuclear power plants, in particular to an emergency water supply system at the secondary side of the nuclear power plant and the nuclear power plant. Background technique [0002] With the development of nuclear power plant technology, people pay more and more attention to the safety of nuclear power plant. Nuclear power plants are generally equipped with an emergency water supply system. When the normal water supply system of the nuclear power plant fails, the emergency water supply system can be used to realize emergency water supply to discharge the heat of the core of the nuclear power plant. Most of the current emergency water supply systems adopt the main pipe water supply method, that is, multiple water supply pipelines in the emergency water supply system share one water supply main pipe and water supply tank, and the above multiple water supply pipelines use the same power source. When the sourc...
