The behavior of special fuel elements that mirror fuel composition as envisioned for large scale transmutation facilities, namely inert-matrix fuels with an increased minor actinide content, are investigated within this reactor environment. | Progress in Nuclear Energy 145 2022 104106 Contents lists available at ScienceDirect Progress in Nuclear Energy journal homepage locate pnucene Inert-matrix fuel for transmutation Selected mid- and long-term effects on reprocessing fuel fabrication and inventory sent to final disposal Friederike Frieß Wolfgang Liebert University of Natural Resources and Life Sciences Vienna Department of Water Atmosphere and Environment Institute of Safety and Risk Sciences Peter-Jordan-Straße 76 I 1190 Vienna Austria ARTICLE INFO ABSTRACT Dataset link https juleylene AD Partitioning and transmutation P amp T fuel cycles provide a technical approach to ease the problem of radioactive waste disposal. Some of the partitioned components of the waste stream are irradiated while others can be used for energy production or are sent to final storage. Minor actinides are planned to be irradiated in Keywords Accelerator-driven-system ADS a fast spectrum nuclear facility to transmute them into stable or short-lived isotopes. As minor actinides have Transmutation negative effects on reactor dynamics subcritical accelerator-driven systems are proposed to increase their Minor actinides MA fraction in the fuel. An example is the MYRRHA research reactor to be built in Mol Belgium. Long-Lived Fission Products LLFP This reactor is modeled for depletion calculations. The behavior of special fuel elements that mirror fuel Inert-matrix fuel IMF composition as envisioned for large scale transmutation facilities namely inert-matrix fuels with an increased minor actinide content are investigated within this reactor environment. It turns out that gamma dose rates activity and residual heat from the spent fuel elements present significant challenges for implementing a P amp T program. Spent inert-matrix fuel element show significantly higher levels than spent fuel elements from fast reactors. This requires long cooling periods and poses .
