Abstract

The dissolved gases in the reactor coolant are first extracted in a separator and then fed to a first reservoir tank before being passed through optional buffer tanks to allow radioactivity decay, to a catalytic reactor chamber for extraction of H2 and/or O2. The gases then pass to a condenser associated with a low temp. still to extract the radio nucleides. Finally the residual inert gases including N2 are passed to a final reservoir whence they may be recycled. Safety and rehability.
