Abstract

The invention provides a nuclear power plant reactor containment air sampling device and method. When the device is used for sampling through the nuclear power plant reactor containment air sampling method, quantitative sampling can be carried out in different sampling modes under normal operation and accident working conditions. Besides, the device is simple in structure, reliable in sampling power, safe and reliable to use and stable and proper in sampling amount and has a function of keeping the temperature of a sample.

Description

technical field [0001] The invention relates to a nuclear power plant reactor containment atmosphere sampling device and method. Background technique [0002] In the operation of nuclear power plants, especially when an accident occurs, it is necessary to sample the atmosphere of the reactor containment to analyze the hydrogen concentration, radioactivity and other information of the atmospheric sample, and then judge the normality of the process system and equipment based on the analysis results. If abnormal, determine the reasonable processing method. Since the sampling object is a gas that may contain radioactivity, it is highly dangerous. In order to avoid impact on personnel and the environment, the sampling volume of the sample must be small and accurate. [0003] At present, according to the requirements of the National Nuclear Safety Administration for the monitoring of atmospheric components in the containment of nuclear power plants under normal operation and acci...
