Název v původním jazyce
Hydrogen sensor report on primary circuit regime
Popis výsledku v původním jazyce
The usage of hydrogen in many industrial branches also necessitates its concentration measurement. In the development of the measurement technique, really selective to hydrogen, we focus on the H2 concentration determination in the primary coolant of a nuclear reactor. To keep optimal process conditions in the primary cooling circuit of nuclear power plants, various chemical species are dosed in and monitored. Hydrogen, together with oxygen, belongs to the key components in the primary circuit chemistry. While a plenty of companies offer oxygen sensors suitable for the measurement in primary coolant, the hydrogen sensor, really selective to H2 concentration, is offered by only one producer. It is worth, therefore, accomplishing the development of hydrogen sensor, which begun at UCT Prague more than two decades ago and was soon interrupted due to fateful events in the research team. Several successful measurements were, however, managed in this millennium beginning in Dukovany nuclear power plant thus promising results were left. We introduce here the results of the contemporary Hmeter development conducted in the Mass Transfer Laboratory. The connection of modern technologies, including electronics, with the experience from 1990's allowed us to develop a functional samples showing good long-term stability. Recently, we verified the usability of our Hmeter at industrial conditions, when our sensor reported primary circuit hydrogen concentrations for 64 days of its installation. Having both long-term stability and the industrial conditions endurance of our sensors confirmed, we are ready to develop a prototype and find the industrial partner to start the production of monitoring units.
