NN Asks: What does it take to build a domestic fuel salt supply chain?
Adam Burak
We need facilities capable of converting uranium and thorium feedstocks into salts, as well as a source of thorium, if we are to build a domestic fuel salt supply chain.
Our current supply chain provides a potential pathway to produce one type of fuel salt. The Molten Salt Reactor Experiment (MSRE) at Oak Ridge National Laboratory used uranium trifluoride/uranium tetrafluoride (UF3/4) as fuel in the late 1960s, and some current developers are following suit. Uranium hexafluoride (UF6) made as part of the enrichment process could be reduced to uranium fluoride salts with a +3 or +4 valence state. However, as oxygen and moisture are critical impurities for molten salt, a facility with the capability to properly handle molten salts would be necessary.

The two media method used to determine the linear attenuation coefficients of irregularly shaped samples without the knowledge of the thickness of the sample has been verified. The linear attenuation coefficient values of regularly and irregularly shaped flyash material samples have been measured by the two media method using five different materials as media. The obtained values of the linear attenuation coefficient were compared with the results of the standard narrow beam gamma-ray transmission method. The results were in good agreement.
