The invention discloses an improved program testing device of a containment spray system of a nuclear power station, aiming at solving the technical problems that the PF improvement program testing of a containment spray system in the prior art can influence a nuclear power unit construction plan and main line debugging and cannot be carried out regularly. The improved program testing device comprises a vehicle-mounted pump, a flow measurement module, a first pressure measurement module, a regulating valve, a first pipeline and a second pipeline, wherein a water inlet of the vehicle-mounted pump is connected with a water supply tank by the first pipeline, a water outlet of the vehicle-mounted pump is connected with the regulating valve by the second pipeline, the flow measurement module and the first pressure measurement module are arranged on the second pipeline, the vehicle-mounted pump is used for guiding spraying water in the water supply tank into the second pipeline, pressure, generated during actual spraying of the containment spray system, inside a containment can be simulated by controlling and adjusting the regulating valve, and the flow measurement module and the first pressure measurement module are used for displaying the water flow rate and the pressure in the second pipeline during the process of controlling and adjusting the regulating valve, respectively.
Description
technical field [0001] The invention relates to the technical field of nuclear power, in particular to an improved test device for the containment spray system of a nuclear power plant. Background technique [0002] The containment is the last barrier to prevent fission products of nuclear fuel and primary radioactive materials from entering the environment. The function of the containment spray system (EAS, Containment Spray System) is to reduce the pressure and temperature in the containment to the acceptable level of the containment in case of accident conditions, so as to ensure the integrity of the containment. Such as figure 1 As shown, it is a structural block diagram of the containment sprinkler system. EAS includes EAS formal system 10 and PF improvement item part 20; EAS formal system 10 includes spray pump 101, pressure gauge LP, EAS heat exchanger 102, flow rate MD and containment dome nozzle 103; PF improvement part 20 includes on-board pump 201 and regulating...
