The progress of the irradiation programme of EFTTRA is described. The results of the T4 test, the transmutation of Americium in a MgAl(2)O(4)-based fuel, are presented. Extensive swelling of the fuel took place, probably due to the damage of the matrix by fission products and/or accumulation of helium because of alpha decay. The lessons learned from T4 and related EFTTRA experiments have lead to a more promising fuel concept based on a macrodispersion of an americium containing host phase in the inert matrix. Two new experiments to test this and other concepts will be presented.
