Abstract
An epithermal BNCT (Boron Neutron Capture Therapy) irradiation station has been constructed at the Finnish Triga reactor. First neutron measurements could be done in May 1996. The results are promising and they show that the optimal moderator material A1+A1F3 works as was predicted by calculations. The construction of the epithermal irradiation station was started summer 1995 when the original graphite filling was removed from the thermal column cavity and was replaced by a temporal water tank. Spring 1996 enough of the new moderator material had been produced to enable the final installation of the epithermal beam. In order to increase the epithermal flux the fuel in the core was rearranged and also some new fuel elements were added so that the most reactive fuel elements were now near the epithermal column. Activation measurements made in the irradiation ring showed that the fast flux was clearly biased to the direction of the epithermal column.
