Reflections on NOW
Hash Hasemianpresident@ans.org
Last month, I talked about my goal of strengthening ANS’s voice, in part by attending three conferences. I have now checked the first event off that list: the Nuclear Opportunities Workshop.
This year, NOW took another step in outgrowing its “workshop” moniker and transitioning to a full-fledged regional conference and expo. What started only a few years ago as a small gathering in Oak Ridge, Tenn., with roughly 50 attendees has skyrocketed to an event with 1,100 people in attendance in Knoxville.
NOW’s popularity reflected how busy the roughly 350 nuclear companies in Tennessee have been in recent years. There is significant work going on surrounding Gen IV reactor development and deployment, advancements in new nuclear fuels, and defense-related builds like the Uranium Processing Facility.

The generation and decomposition behavior of nitrous acid is experimentally investigated during dissolution of unirradiated uranium dioxide (UO2) pellets by a nitric acid solution. The nitrous acid is generated by the dissolution of UO2 and it then decomposes to nitrogen oxides through the solution surface. The generation rate is equal to the dissolution rate of the uranium pellet and it depends on the nitric acid concentration, solution temperature, and effective pellet surface area. The decomposition rate depends on the solution surface area and temperature. These findings allow prediction of changes in nitrous acid concentration during and after dissolution.
