Abstract: Abstract The objective of this work consists in the analysis of a half-life distribution shift of fission products by coupled fission-fusion processes. In this concept the kinetic energy of the fission products is responsible to overcome the electrical repulsion between the nuclei after fission. Here we consider the following light elements for the fusion process: hydrogen, deuterium, lithium and beryllium with mass fractions of 3.0. The choice of these elements was performed by analysing the binding energy, the atomic number and experimental fusion cross sections. The assessment of fusion was performed via the uncertainty principle, since there is no model that could cover a large number of possible reactions. The probability of reaction was approximated as a function of the probability of a fission product to find a particular light element. Additionally times were calculated for the electronic stopping of fission products, where was found that scale of stopping does not impose limits on possible fusion. The main change due to the addition of the targets was the distribution of half-lives of the fission products, towards longer times. This change and its average magnitude indicates that it is possible to reduce the average activity of the nuclear waste, in particular the high level of radioactivity, making waste handling safer. The targets of hydrogen and lithium showed the best results for increasing the half-life of the average fission products, managing a change on the average of two orders of magnitude.
