Description

Technical Field

[0001] The present invention relates to the technical field of safety testing devices, and in particular to a safety testing device for a nuclear power control system. Background Art

[0002] Nuclear power refers to the technology of using the thermal energy generated by nuclear reactions (usually nuclear fission) to generate electricity. A large amount of heat is released during fusion or fission, and the energy is converted according to the formula of nuclear energy-mechanical energy-electrical energy. This kind of electricity can be called nuclear power. Nuclear power plants convert nuclear energy into thermal energy through nuclear reactors, which is then used to heat water to generate steam, driving steam turbine generators to generate electricity. Nuclear power is considered to be a relatively clean energy because it emits almost no greenhouse gases during the power generation process.

[0003] For example, the authorization announcement number CN114740753A discloses a nuclear power control system safety test environment simulation device. Although it is installed on the disk body by the combination of bolts and threaded holes, when it is used, the disk body is taken out from the inner cavity of the box body, and the simulation model is installed on the disk body, and then the disk body with the simulation model installed is placed in the inner cavity of the box body for simulation. It can be matched according to the scale of nuclear power and simulate nuclear power plants of different scales, saving the cost of simulation. However, this method is not convenient enough in actual use. When it is used, the door body needs to be opened before it can be used, which makes the process of taking and placing the ladder inconvenient.
