The invention is applicable to the technical field of nuclear power safety, and provides a method and a device for verifying an accident application function of a nuclear power plant backup accident mitigation power supply. The method comprises steps: a hydrostatic test power supply system is connected with an additional accident mitigation power supply system, and the power supply circuit for the hydrostatic test power supply system is used as a power supply circuit for the additional accident mitigation power supply system; power supply voltage of the additional accident mitigation power supply is introduced to a power supply control panel, the power supply voltage is transmitted to a hydrostatic test pump load, and a hydrostatic test pump is driven to operate; a test window is arranged to carry out operation test on the hydrostatic test pump, and test data are acquired; and according to the test data, the stability of the additional accident mitigation power supply is verified. The additional accident mitigation power supply is used for providing power for the hydrostatic test pump to start the hydrostatic test pump to operate, verification on the stability of the additional accident mitigation power supply is realized, the emergency processing capability and the response speed for an emergency can be improved, and hidden nuclear power safety dangers can be reduced.
Description
technical field [0001] The invention belongs to the technical field of nuclear power safety, and in particular relates to a method and device for verifying application functions of nuclear power plant backup accident mitigation power supply accidents. Background technique [0002] On the afternoon of March 11, 2011, the regrettable Fukushima nuclear crisis broke out in Japan. The external power supply was cut off due to the earthquake, and the backup diesel generator was also destroyed by the tsunami. Although the nuclear reactor was saved, due to the loss of power supply, The cooling water source of the reactor could not be maintained, causing the core to melt, the plant to explode, and a large amount of radioactive materials to leak out, causing very serious consequences. Therefore, in the subsequent accident analysis, it is determined to configure additional accident mitigation power as a backup means for mitigating accidents after accidents beyond the design basis, so as...
