Abstract

The invention particularly relates to an emergency water replenishing device for accident conditions of a nuclear power plant. The emergency water replenishing device comprises a movable water taking device and a movable water conveying device. The water source is connected with a water inlet of the movable water taking device, a water outlet of the movable water taking device is connected with a water inlet of the movable water conveying device, a water outlet of the movable water conveying device is connected with a water inlet of the movable water supplementing vehicle, and a water outlet of the movable water supplementing vehicle is connected with the emergency water supplementing point. The movable water conveying device is a trailer platform, and the movable water taking device is dragged to move under the accident condition. According to the emergency water replenishing device for the accident conditions of the nuclear power plant, water can be continuously and stably supplied to the primary loop, the secondary loop and the spent fuel pool remotely under the condition that a serious accident occurs in the nuclear power plant, so that heat of a reactor core is taken away, and the serious accident coping capacity and the nuclear safety level of the nuclear power plant are further improved.

Description

technical field [0001] The invention relates to the technical field of safety auxiliary facilities of nuclear power plants, in particular to an emergency water supply device for nuclear power plant accident conditions. Background technique [0002] Severe accidents are accident conditions that are more severe than design basis accidents and where the performance of the core deteriorates severely. Under severe accident conditions, the normal water supply for core cooling and spent fuel cooling within the design basis may not be available, and emergency water supply facilities are required for water supply. [0003] In March 2011, a severe nuclear accident occurred at the Fukushima nuclear power plant in Japan due to a strong earthquake and tsunami. After the Fukushima nuclear accident, domestic nuclear power plants have learned the experience and lessons of the Fukushima accident, carried out the transformation of emergency water supply facilities, and added emergency water ...
