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.

The multiphase, transient, and three-dimensional interaction of molten corium with water during the premixing phase of a steam explosion is simulated in the QUEOS facility using a large number of small solid spheres at temperatures up to 2300 K. The objective of the experiments is to establish a database for testing the models of heat and momentum transfer in multifluid codes as well as the codes' capability to correctly describe multiphase flows. Three experiments with up to 10 kg of spheres made of molybdenum are discussed. Results from calculations with the IVA-KA code are compared with experimental data. The agreement obtained is encouraging, and the calculations show that the intense multiphase interactions obtained in QUEOS constitute very critical and thus valuable test cases.
