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 combined use of nitric and formic acids, in lieu of formic acid alone, to reduce H2 emissions during the treatment of high-level radioactive waste sludge was investigated. The H2 generation can be mitigated substantially by substituting a fraction of formic acid with nitric acid as the required acid source, and then using formic acid as the required reductant source. The peak H2 generation rate was reduced by more than a factor of 2, and a more gradual rise in the H2 evolution resulted. However, the addition of mercury to the sludge increased the evolution of H2 as did increasing the amount of nitric acid used and the rate of addition of the formic acid source. Overall, these results provided clear insight into what controlled the evolution of H2 from high-level waste sludge and a means of mitigating it.
