ANALYTICAL-CHEMISTRY IN CONTROLLED THERMONUCLEAR FUSION

The analytical problems arising in the fuel cycle of a fusion reactor have to be discussed separately for the various subsystems of such a r eactor. Thus, in the case of plasma exhaust purification, concentratio n assays of the tritiated impurities must be carried out quickly and, whenever possible, under flow conditions. Conventional methods may be employed for this purpose, such as mass spectrometry, FT-IR spectromet ry and laser Raman spectrometry, but they will all have to be adapted to special conditions, especially for online operation.
