Abstract

In the frame of the European fusion reactor materials research programme (MAT 6 / MAT 13) different ceramics are investigated as possible candidate materials for the first wall protection of the NET. Part of this investigation consists of irradiation in the HFR Petten, of ceramic specimens with required damage level of 10 dpa which corresponds to a nominal fluence of 10**26 nm**-2, E > 0.1 MeV. The irradiation facility consists of 3 legs in a trefoil arrangement in one lattice position. Two legs, (High Temperature) will house specimens to be irradiated at 1200$)DC, one with KfK and the other with CEA specimens. The third leg, (Low Temperature) houses specimens from various European laboratories. The specimens for the Low Temperature leg are accommodated in Aluminium drums whereas for the High Temperature, in Molybdenum drums. The required specimen temperatures are obtained solely by means of nuclear heating and by axially tailoring of gas gaps with appropriately varying gas mixtures. The three sample holders can be moved axially in order to maintain the desired temperature levels.
