Original language description

DEVELOPMENT OF HELIUM PURIFICATION AND PURITY CONTROL METHODOLOGY FOR HIGH TEMPERATURE HELIUM LOOP IN NRI ŘEŽ, PLC. Within the scope of commissioning of High Temperature Helium Loop (HTHL) in NRI Řež plc. methods of helium purification and purity controlare developed. In the first period the research was aimed to capacities of obtainable adsorbents for removal of impurities expected in helium in HTHL. At the same time development of analytical methods for monitoring of impurities concentration in helium based on gas chromatography with Helium Ionization Detector and infra red spectroscopy were developed and improved. In helium coolant of Very High Temperature Reactor (VHTR) hence in helium in HTHL these impurities are expected: CO, CO2, H2, H2O, CH4,O2, N2. Concentrations of these compounds are not range from approx. 0,1 ? 1000 ppmv. During first period of experiments removal of CO, CO2, CH4 and H2O on selected adsorbents was tested in laboratory-scale apparatus. According to results
