Embodiment Construction

[0028] Such as figure 1 Shown is an embodiment of the reactor safety system of the present invention, which can take out heat in an accident state, and has the functions of preventing reflective release and cooling the containment, which greatly improves the reliability and safety of the nuclear power plant.

[0029] The reactor safety system includes a containment vessel, a steam generator 30 disposed in the containment vessel, a reactor core 40, a reactor chamber, etc., and of course some connecting pipelines and other equipment in the containment vessel, etc., which will not be described in detail here.

[0030] The containment vessel is a double-layer containment vessel, including a containment vessel inner wall 11 and a containment vessel outer wall 12 disposed on the periphery of the containment vessel inner wall 11 . An accommodating space 13 is formed between the containment inner wall 11 and the containment outer wall 12, and the accommodating space 13 is filled with ...

Abstract

The invention relates to a reactor safety system, which comprises a safety shell, a steam generator arranged in the safety shell, a reactor core, a reactor cavity and a cooling pipeline; the safety shell comprises an inner safety shell wall and an outer safety shell wall arranged at the periphery of the inner safety shell wall; an accommodating space is formed between the inner safety shell wall and the outer safety shell; and the accommodating space is filled with cooling liquid to form a passive cooling water tank; and the cooling pipeline is communicated with the accommodating space and injects the cooling liquid into the safety shell. The system can be used as a containment spraying system, and is used for injecting into the steam generator and the reactor core to carry away heat fromthe reactor core, and injecting into the reactor cavity to carry way heat outside a pressure vessel so as to prevent the pressure of the safety shell from rising, the reactor core from damage and thepressure vessel from out of work. Moreover, the system has the functions of preventing radioactive release and cooling the safety shell, so that the reliability and the safety of a nuclear power station are greatly improved.

Description

technical field [0001] The invention relates to the technical field of nuclear power, in particular to a reactor safety system applied to the containment of nuclear power plants. Background technique [0002] With the maturity of technology and the continuous improvement of the safety of nuclear power plants, the construction of nuclear power plants has gradually become an important energy guarantee for national development. [0003] In the current nuclear power plant, the structure of the nuclear reactor is: a reactor cavity is formed in the containment vessel, a reactor core (pressure vessel) is set in the reactor cavity, and the pressure vessel is connected to a steam generator. In order to ensure the safety of nuclear reactors, various safety injection systems need to be installed. In the event of a loss of water accident (LOCA), coolant is injected into the reactor cavity, core, steam generator, etc. in the containment for cooling. If the power supply is lost at the sa...
