The transmutation of fission products by resonance capture is shown to be possible by using a moving concept target. Instead of controlling the neutron energy to irradiate the nuclei, the nuclei to be transmuted are accelerated toward a neutron thermal field. The transmutation rate of 99Tc is then reduced from 2.1 105 years to 14 hours. Possible experimental devices to realize this moving target and the required confinement time are described and studied briefly. They include a device using microparticles of fission products, as well as a concept derived from magnetic fusion. Both are compared with a different concept issued from inertial fusion.
