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.

CERN is at present designing a new chain of accelerators to replace the present Proton Synchrotron (PS) complex: a 160-MeV room-temperature linear accelerator (linac) (Linac4) to replace the present 50-MeV linac injector, a 3.5-GeV superconducting proton linac (SPL) to replace the 1.4-GeV PS booster, and a 50-GeV synchrotron to replace the 26-GeV PS. Linac4 has been funded, and civil engineering will start soon, while the SPL is in an advanced stage of design. Beyond injecting into the future 50-GeV PS, the ultimate goal of the SPL is to generate a 4-MW beam to produce intense neutrino beams. The radiation protection design is driven by the latter requirement. This work summarizes the radiation protection studies conducted so far for Linac4. The calculations of the shielding, access maze, ducts for cables, waveguides, and ventilations were performed with the FLUKA Monte Carlo code, complemented by analytical estimates.
