U.S. nuclear supply chain: Ready for liftoff
Craig Piercycpiercy@ans.org
This month, September 8–11, the American Nuclear Society is teaming up with the Nuclear Energy Institute to host our first-ever Nuclear Energy Conference and Expo—NECX for short—in Atlanta. This new meeting combines ANS’s Utility Working Conference and NEI’s Nuclear Energy Assembly to form what NEI CEO Maria Korsnick and I hope will be the premier nuclear industry gathering in America.
We did this because after more than four decades of relative stagnation, the U.S. nuclear supply chain is finally entering a new era of dynamic growth. This resurgence is being driven by several powerful and increasingly durable forces: the explosive demand for electricity from artificial intelligence and data centers, an unprecedented wave of public and private acceptance of—and investment in—advanced nuclear technologies, and a strong market signal for reliable, on-demand power. Add the recent Trump administration executive orders on nuclear into the mix, and you have all the makings of an accelerant-rich business environment primed for rapid expansion.

Photochemical techniques are used for the mutual separation of lanthanide elements. By emitting light from an ultrahigh-pressure mercury lamp to a nitric acid solution that contains fourfold mixtures of lanthanide elements (neodymium, samarium, europium, and gadolinium), (NH4)2SO4, and isopropyl formate, neodymium, samarium, and europium are photoreduced and form Ln2+ sulfates, while gadolinium is not photoreduced and does not coprecipitate. When lanthanum is introduced instead of gadolinium, lanthanum coprecipitates along with neodymium, samarium, and europium. These results are explained by photolyzing Nd-Gd and Nd-La systems for comparison, and the difference in precipitation behaviors between these two systems is explained by the differences in ion size of these elements. Photolysis is also performed for a Nd-Am system. Am3+ is carried along with neodymium and coprecipitated. As a way to decrease the amount of americium carried along with neodymium, americium is photo-chemically oxidized by emitting light from a deuterium lamp as well as from a mercury lamp. The fraction of americium carried with neodymium decreases with the use of this technique. This result is also explained by the differences in ion size of these elements.
