Reactor / Coolant

Dissolved oxygen and hydrogen are critical parameter in the water chemistry of the reactor coolant system (RCS). Without proper measurement and control of these dissolved gases operation of the nuclear plant is impossible. Orbisphere analyzers provide accurate, fast-responding dissolved gas measurement to below 1 ppb. MDTC hydrogen measurement technology is unsurpassed in accuracy and requires minimal maintenance. Dual-channel analyzers with both oxygen and hydrogen measurement automatically compensate for hydrogen interference on trace level oxygen measurement. Orbisphere sensor technology distinguishes hydrogen from helium for RCS applications that experience increased amounts of dissolved helium.
