The application of phase separation in the determination of hydrogen dissolved in the primary circuit of nuclear power plant

Developing a method for determining hydrogen dissolved in the cooling water from nuclear heating reactor by phase separation. With nitrogen as the carrier, through the water pressure reduction and nitrogen bubbling, drive hydrogen dissolved in the cooling water from nuclear heating reactor into gas phase, and analyze by gas chromatography. This method is applicable to the determination the concentration of hydrogen dissolved in the cooling water from nuclear heating reactor. (authors)
