1. In a system for disposing of radioactive gaseous wastes in a nuclear power plant of the type comprising: a steam turbine;  a first condenser connected to the steam turbine;  a vertically cylindrical recombining unit connected to the first condenser and comprising preheating means for preheating to a predetermined temperature radioactive gaseous wastes fed from the first condenser and catalytic recombining means which forms water vapour from oxygen and hydrogen contained in the radioactive gaseous wastes;  a second condenser connected to an output of said recombining unit; and  means connected to an output of said second condenser for adsorbing and holding up the radioactive gaseous wastes with an adsorbing agent;  the improvement in which said recombining unit is dividable into an upper half in which said recombining means is disposed and a lower half in which said preheating means is disposed, there being a space between said recombining means and said preheating means, said second condenser being disposed downstream of and in direct contact with said recombining unit, and in which the radioactive gaseous wastes are fed from said first condenser into said recombining unit at a portion of said recombining unit near the bottom thereof and pass through said preheating means, said recombining means, and into said second condenser through a portion of said recombining unit near its upper end.
