Abstract
A procedure based on infiltration of aqueous metal solutions into pell ets has been demonstrated for the production of targets containing hig hly radioactive materials. These targets will be used in the study of actinide transmutation and incineration (EFTTRA-T4). Impregnation of M gAl2O4 (spinel) pellets, with a green density of 50%, by an americium nitrate solution yielded pellets containing 8% americium. Following si ntering the pellet densities were in the 96-98% range. The pellets are composed of two phases corresponding to spinel and an americium oxide . The Am phase is present as small particles with dimensions less than 2-3 mu m, which are evenly distributed throughout the material. (C) 1 997 Elsevier Science B.V.
