The EXOTIC project is a contribution of NRG Petten to the European FusionTechnology Programme on ceramic tritium breeding materials for the Helium Cooled Pebble-Bed blanket concept. The irradiation of specimen holder EXOTIC-8/1 (R212-8/1) in the HFR Petten, loaded with Li2TiO3 pebbles, is part of this programme. The R212-8/1 assembly was irradiated in channel 1 of a TETRA type facility in the peripheral HFR core position H2 during eight HFR cycles ending March 1998. This report presents the final neutron metrology results obtained from activation monitor sets as well as from gamma scan wires situated inside the specimen holder. The main result of the thermal and fast neutron fluence measurements and the calculated amounts of tritium produced are presented. 19 refs.
