Embodiment Construction

[0052] In the related art, the noble gas monitor of the high temperature gas-cooled reactor nuclear power plant process radiation monitoring and radioactive effluent monitoring system is specifically used to continuously measure the γ / β ray activity concentration of the noble gas in the radioactive gas sample. During the equipment debugging period, it is necessary to verify whether the alarm function of the monitor can be realized normally. The verification method is as follows: figure 1 As shown, put the radioactive source of preset intensity into the radioactive source detector to obtain the detection signal, and the detection signal is processed by the processing unit to obtain an analog signal. When the alarm function is normal, the monitor can respond to the analog signal. Conversely, when the monitor can respond to the analog signal without an alarm, it can be determined that the alarm function is abnormal. Although this method can verify whether the alarm function of th...

Abstract

The invention discloses an alarm function verification method and device and a radioactive source monitor, the alarm function verification method is used for verification of the alarm function of the radioactive source monitor, and the method comprises the steps: generating a pulse signal with a preset frequency, and the preset frequency is determined according to an alarm value of an alarm unit; processing the obtained pulse signal with the preset frequency to generate an analog quantity signal; and determining the effectiveness of the alarm function according to whether the analog quantity signal triggers the alarm unit to give an alarm. The problem of inaccurate verification caused by unstable output of the radioactive source in an existing verification method can be solved, the risk that workers are damaged by radioactive irradiation due to the use of the radioactive source can be avoided, and meanwhile, the debugging period can be shortened.

Description

technical field [0001] The application belongs to the technical field of instrument control and debugging of high temperature gas-cooled reactor units in nuclear power plants, and in particular relates to an alarm function calibration method, device and radioactive source monitor. Background technique [0002] In the high temperature gas-cooled reactor nuclear power plant, the demonstration engineering process radiation monitoring and radioactive effluent monitoring system contains multiple high / low range noble gas monitors to monitor the activity concentration of γ-ray and β-ray in the gas in the environment and equipment pipelines . During equipment commissioning, it is usually necessary to verify the functional integrity of the monitor. In addition to the normal appearance inspection and stand-alone function inspection, the alarm function of the monitor also needs to be calibrated. The calibration method is to use the radioactive source for alarm calibration, but because...
