Concepts for inert-matrix fuels for americium transmutation are discussed. It is concluded that in principle a dispersion of the americium phase is to be preferred to solid-solution in order to localize the damage to the matrix due fission fragments to a small volume. Such a dispersion is composed of spherical inclusions of host phase, which contains the americium, in a dense inert matrix. Because this concept combines the advantages of dispersion and solid solution fuels, it is called 'hybrid' fuel.
