Simulation running apparatus for passive safety master system of pressurized water reactor nuclear island

Abstract

The invention discloses a simulation running apparatus for a passive safety master system of a pressurized water reactor nuclear island, and belongs to the technical field of nuclear energy. The structure of the simulation running apparatus is that: a reactor core makeup water tank, a first electromagnetic valve, a second electromagnetic valve, an accumulator, a pressure vessel, an eighth thermal couple, an ink injector and a valve are assembled together through a pipeline, wherein the ink injector, a voltage regulator, a safety valve, a second pressure meter, a relief valve and a valve are assembled together through a pipeline; and the ink injector, a third thermal couple, a vapor generator, an injection pump and a valve are assembled together through a pipeline. The simulation running apparatus has the advantages that circulating processes of a first loop and a second loop under a normal working condition in a containment vessel of a nuclear island of a nuclear plant and running processes of a safe injection system and a passive residual heat removal exchanger under a loss of coolant accident (LOCA) working condition can be directly known.

Description

technical field [0001] The invention belongs to the technical field of nuclear power energy, and in particular relates to a simulation operation instrument for a main system of a passive safety pressurized water reactor nuclear island. Background technique [0002] The inside of the nuclear island containment of the nuclear power plant is strictly sealed, so that the employees of the nuclear power plant and students majoring in nuclear power cannot understand the circulation process of the first and second loops under normal working conditions and the safety injection system and passive waste heat under the conditions of LOCA loss of water accidents. There is an intuitive understanding of the operation of the discharge heat exchanger. At present, most of the demonstration models widely used in teaching are static models made of plastic or foam, which cannot realize the dynamic simulation of each operation process.
