Abstract

Experiment EXOTIC-6 is one of a series of in-pile tests of ceramic breeder materials for fusion reactors with in situ tritium release measurements. The irradiations are performed in the High Flux Reactor (HFR) Petten. Various materials have been tested at different temperatures using helium + 0.1% H(2) as reference purge gas. During irradiation a number of temperature steps were performed from which tritium residence times have been determined. The tritium residence time is a good measure to compare the various breeding materials with respect to the tritium release characteristics. The main objective of EXOTIC-6 was to determine the effect of the purge gas composition on the release of tritium. The purge gas composition was changed from He + 1% H(2) to pure helium, with and without water vapour. Preliminary results of these experiments are reported.
