This document ensures that technologies relevant to LL20-ML-AIT-NE-1-PD3TB “AIT-NEO” have been demonstrated to work as intended and at the appropriate technology readiness level. This assessment is intended to offer management tools for understanding and mitigating programmatic risks associated with new technologies being developed under the AIT-NEO effort.
A novel neutron radiographic technique was developed and implemented to measure the change in volume as a function of temperature of select plutonium-containing liquid chloride mixtures from melt to 1250 K. These measurements were performed at Los Alamos National Laboratory by members of the molten salt research group under support from Gateway for Accelerated Innovation in Nuclear (GAIN) voucher NE-21-25117: “Density Measurements of Plutonium Bearing Salts via Neutron Beam Dilatometry”.
