Radionuclide Source Term for Irradiated Fuel from Prototype, Research and Education Reactors, for Waste Forms with Negligible Heat Generation and for Uranium Tails

Beschreibung

Radionuclide source terms are derived for different disposal options of a potential final repository in the salt dome Gorleben. The geochemical conditions are analyzed under the precondition that NaCl, MgCl2- or CaCl2-rich solutions are present. Kinetic and thermodynamic mobilization/retention and the influence of temperatures are discussed. Upper limit concentrations for the radionuclides Am, Th, U, Np, Pu, Tc, Zr and rare earth elements are derived for the simplified scenarios.
