INL makes first fuel for Molten Chloride Reactor Experiment
Idaho National Laboratory has announced the creation of the first batch of enriched uranium chloride fuel salt for the Molten Chloride Reactor Experiment (MCRE). INL said that its fuel production team delivered the first fuel salt batch at the end of September, and it intends to produce four additional batches by March 2026. MCRE will require a total of 72–75 batches of fuel salt for the reactor to go critical.

Inelastic scattering of 25.7-MeV neutrons to unresolved final states with excitation energies up to ∼13 MeV were measured for monoisotopic samples of 51V, 56Fe, 65Cu, 93Nb, and 209Bi. Neutrons were produced via T(d,n)4 He reaction in a gas cell that provides a background-free source spectrum above En = 12 MeV. Time-of-flight spectra were taken at several angles between 25 and 145 deg using the beam-swinger spectrometer. The technique of dynamic biasing proved valuable in providing maximum detector efficiency and low background throughout the broad range of neutron energies. Data were converted to energy spectra, corrected for detector efficiency, averaged over 1-MeV bins, and corrected for sample attenuation and multiple scattering.
