ABSTRACT:
A quantity of tritium of less than 1 mol per hour is continuously withdrawn from the vaporization chamber of a low-temperature rectifying column by means of a withdrawal system.
The withdrawal system consists basically of two parallel-connected vacuum tanks which are alternately connected to the vaporization chamber via a withdrawal line containing a control valve. During operation, one of the vacuum tanks is connected to the low-temperature rectifying column and filled with tritium. As soon as one of the vacuum tanks has been filled with tritium, emptying of the tank starts while the second vacuum tank is connected to the vaporization chamber and similarly filled and then emptied.
