Technology Description:

General Electric (GE) Global Research, in partnership with Lumitron Technologies, Orano, and Sandia National Laboratory, will research an innovative safeguards solution, Monochromatic Assays Yielding Enhanced Reliability (MAYER), for aqueous reprocessing. MAYER will leverage a novel, compact, high-flux, low-bandwidth laser Compton scattering photon source for ultra-fast, high-precision (<1% uncertainty and <2 minutes) in situ fissile elemental and isotopic measurements; design a unique aqueous reprocessing facility safeguards digital twin (DT) to facilitate continuous, on-demand artificial intelligence training to lower standard errors in materials inventory, predict adverse events, and enable mitigation before a required facility shutdown; and explore a distributed ledger technology to ensure safeguards for sensor data security, transparency, and integrity for regulatory auditing and DT usage.

Potential Impact:

By enabling the secure and economical recycling of the nation’s inventory of LWR UNF, CURIE will have the following impacts:


Support the deployment of advanced reactor (AR) technologies by providing safe and sustainable domestic fuel stocks. Improvements in monitoring capabilities could enable more precise controls of various reprocessing stages while ensuring increased security of materials of concern.


Substantially reduce the disposal impact of the nation’s inventory of LWR UNF, decrease uranium mining requirements, and support a comprehensive national strategy to store radioactive waste safely and securely.


Complement ARPA-E’s existing nuclear energy research portfolio, further ensuring the commercial viability of innovative new ARs, and enable an additional revenue stream via valuable radionuclides recovered from UNF for diverse applications.
