This panel session aims at discussing the innovative waste management options for shortening the radiotoxic period of wastes occurred from SNF P&T. The P&T technology makes it possible to recycle valuable radio-nuclides as transmutation targets or fuels and intensively treat critical radio-nuclides to environment. Because wastes arising from the P&T have little amounts of LLFP and TRU than SNF, therefore, it is expected to reduce the thermal load and total radioactivity. Options such as a deep geological disposal or deep borehole disposal could lead to the innovative ideas to shorten institutional control period on these wastes.

Discussion & Path forward will be moderated by Kun-Jai  H. Ait Abderrahim. Panelists and Topics include:
