The use of GFR dedicated assemblies in the frame of advanced symbiotic fuel cycles: an innovative way to minimize the long-term spent fuel radiotoxicity

Description

Transmutation is one of the most promising strategies to minimize Minor Actinides inventories. Particularly, during NPPs operation, Am and Cm isotopes are generated by capture and transmutation processes from U and Pu. High neutron flux (typical of fast reactors) and high neutron capture cross-section can help to implement such strategy. Fast Reactors charged with some moderated Dedicated Assemblies (DAs) could supply such requirements for transmutation process. DAs are filled with MA and are inserted in the active core with the aim of optimizing and improving the reactor burning capability. Such optimization of the layout and the analysis of the results obtained are the main topics of the work.
