Off-Gas treatment

Hydrogen and oxygen are generated in the reactor during power operation by radiolysis. By the primary coolant transfer to the auxiliary systems degassing of hydrogen and oxygen can result in an unintended accumulation of hydrogen. Framatome recombination unit reduces the hydrogen and oxygen concentration by catalytically recombining hydrogen and oxygen to water. Gaseous tritium is transferred to the liquid phase for further treatment.
