Demonstration device of pressurized water reactor nuclear power plant passive residual heat removal system

Abstract

The invention discloses a demonstration device of a pressurized water reactor nuclear power plant passive residual heat removal system. The demonstration device comprises a cooling device which is provided with a water inlet and a water outlet and used for simulating a passive cooling water tank; a heater which is provided with a water inlet and a water outlet and used for simulating the residual heat generated by the reactor core, wherein the water level of the cooling device is higher than that of the heater; a circulating water pipe which comprises a water inlet pipe and a water return pipe, wherein the water inlet pipe is connected with the water outlet of the heater and the water inlet of the cooling device, and the water return pipe is connected with the water outlet of the cooling device and the water inlet of the heater; and a control system which is connected with the heater in a signaling way and used for controlling the heater. The complex process of the passive residual heat removal system can be displayed in a visual mode.

Description

technical field [0001] The invention relates to the technical field of principle demonstration of a safety system of a nuclear power plant, in particular to a demonstration device for a passive waste heat discharge system of a pressurized water reactor nuclear power plant. Background technique [0002] After the nuclear reactor is shut down, a large amount of decay heat will be generated. This part of the decay heat needs to be discharged to the final heat sink by using a special waste heat removal system for a long period of time, so as to avoid the temperature and pressure in the pressure vessel due to heat accumulation. Too high to destroy the integrity of the pressure boundary. Modern nuclear power plants use a large number of active equipment to realize the function of waste heat discharge. However, the reliable operation of these equipment requires an external stable power source. Once the system fails or there is a serious accident in which the entire plant is powered...

Problems solved by technology

However, the passive waste heat removal system is relatively complicated. When conducting personnel training, it is not possible to visit and understand the nuclear power plant many times, so the personnel training effect is poor. If the operator cannot fully master the passive waste heat removal system, it will be difficult for the future work will bring certain obstacles
