Abstract

Pyroprocessing holds the key to unlocking a more sustainable future for nuclear energy by handling various types of spent

nuclear fuel (SNFs) and reducing radioactive waste volumes. This review examines the role of electrochemical monitoring

in molten salt pyroprocessing of SNFs, emphasizing its importance in enhancing process effi ciency and nonproliferation.

Challenges associated with the monitoring of multi-element environments, fl ow environments, and sensor stability

are discussed. The review suggests that integrating sensor technology with artifi cial intelligence could lead to signifi cant

advancements in the field.
