Abstract: Example embodiments relate to methods of controlling hydrogen concentrations in an offgas system of a nuclear reactor by passive air injection. A method according to a non-limiting embodiment may include passively injecting ambient air through the hydrogen water chemistry system into an existing offgas line of the offgas system. The offgas line is configured to transport non-condensable gases, including hydrogen, from a condenser to a recombiner. As a result of the passive air injection, the combined flow of hydrogen and oxygen react in the recombiner to form water vapor, thereby reducing the hydrogen concentration of the offgas exiting the recombiner.
