Researchers with the Massachusetts Institute of Technology, working with scientists from Lawrence Berkeley National Laboratory and the University of Orléans, have modeled radionuclide behavior in deep geologic formations, offering a tool for developing a defensible safety case for the underground disposal of radioactive waste.
