Patent No.: ZL 2019 1 1293385.4e466d1ab2c994ae402e73753f29e821e.jpg
System Configuration:
The containment hydrogen concentration monitoring system consists of hydrogen sensor probe modules, a processing cabinet, signal cables, and other components.
System Functional Design:
The probes continuously measure hydrogen concentrations within the range of 0–25 vol.% under severe accident conditions inside the containment, including temperatures of 0–180°C, pressures of 0–0.7 MPa, and relative humidity of 0–100% RH. The processing cabinet receives and further processes the probe signals. Its functions include power supply processing and redundancy, remote-control input and output, probe signal acquisition, processing and control, display, alarms, and 4–20 mA signal output.
Overview:
The invention relates to a palladium-based ternary alloy hydrogen-sensitive material comprising the following components by atomic percentage: Pd, 85%–95%; Y, 5%–12%; and Ru, 0.1%–5%. The invention also provides a palladium-based ternary alloy hydrogen-sensitive film, a composite hydrogen-sensitive element incorporating the film and its preparation method, and a palladium-based ternary alloy thin-film hydrogen sensor. Compared with hydrogen-sensitive films made from conventional binary alloy materials, the palladium-based ternary alloy film developed in this invention provides higher activation energy and hydrogen solubility, resulting in stronger hydrogen adsorption capacity, a greater number of hydrogen atoms accommodated per unit volume, and more complete dissociation following adsorption. As a result, hydrogen-sensitive elements and hydrogen sensors incorporating this film offer improved overall performance.
