In the IFMIF Lithium target system, the total lithium inventory is about 21
m(3) and the impurities in the lithium are controlled by a cold trap and a
hot trap. From the safety standpoint, the control of tritium and beryllium
-7 concentration in the lithium is the most important issue. Both elements
are to be controlled by a cold trap. As an option for the tritium, a hot tr
ap is also considered. Other impurities such as oxygen, nitrogen and carbon
which will affect the compatibility of lithium and loop materials are also
controlled by the cold and hot traps to an acceptable level, A swamping me
thod to control the tritium concentration is analyzed. (C) 1998 Published b
