Abstract: A system for concentrating a solution of boric acid solution to a predetermined concentration and stripping the radioactive gases from the solution. The system is generally operable so that there is a continuous feed of weak boric acid solution and a continuous discharge of pure water from the system during the concentrating portion of the cycle and the system is operable so that when the boric acid solution reaches a predetermined concentration, the weak acid feed and pure water discharge are shut off, the pure water is recirculated through the system until the boric acid of predetermined concentration is removed to storage tanks. The system has sequentially operated controls which minimize the thermodynamic shock as the system is switched from the recycle portion of the cycle to the distillate discharge portion of the cycle.
