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.

This work aims to investigate major operation parameters including scan uniformity, film orientation, scan resolution, image region of interest, energy dependence, postirradiation coloration, and ambient temperature in order to establish an appropriate protocol for calibration and dose measurement using a GafChromic film dosimetry system. A two-dimensional dosimetry system comprising GafChromic films and an Epson Expression 1680 flatbed document scanner was employed. EBT films in a 30- × 30- × 25-cm3 solid water phantom were exposed in a photon field delivered by a Varian 21EX electron linear accelerator with a 10- × 10-cm2 field size. The operation parameters of the GafChromic film dosimetry system were investigated in detail. The dose profile measurement was compared with calculation delivered by the Varian Eclipse treatment planning system. Some deviations in the penumbra regions were found.
