[0027] The present invention will be described in detail below with reference to the drawings and embodiments.
[0028] The invention provides a nuclear power hydrogen concentration detection device, such as figure 1 As shown, the device includes a hydrogen concentration sensor array 1, a standard gas chamber 2, an optical coupler 3, a light source 4, a photoelectric converter 5, a signal processing unit 6 and a computer output unit 7.
[0029] among them:
[0030] (1) The hydrogen concentration sensor array 1 is composed of a plurality of fusion cone-type optical fiber hydrogen sensors S1 to SN, and the outside of the optical fiber fusion cone area in the optical fiber hydrogen sensor is coated with palladium metal to form a palladium film. Each optical fiber hydrogen sensor is installed in the nuclear power containment n in the form of multi-point distribution, specifically, installed at each hydrogen concentration monitoring point in the nuclear power containment n, and each opti...
