Nuclear News 40 Under 40—2025
Last year, we proudly launched the inaugural Nuclear News 40 Under 40 list to shine a spotlight on the exceptional young professionals driving the nuclear sector forward as the nuclear community faces a dramatic generational shift. We weren’t sure how a second list would go over, but once again, our members resoundingly answered the call, confirming what we already knew: The nuclear community is bursting with vision, talent, and extraordinary dedication.

Currently, there is an ongoing international effort to develop and characterize W alloys that are suitable for fusion applications. In this report, five key W alloys were examined for the advanced divertor design of ARIES-ACT - the latest ARIES tokamak design. The most promising alloys appear to be W-1.1TiC and W-La2O3. At the end of the divertor lifetime (~4 years), the maintenance dose of these alloys very closely matches those of W with nominal impurities. Unfortunately, even with pure W, the divertor is not clearable, which indicates that it must be recycled or disposed of in a geological repository. The radiation damage and transmutation are expected to degrade the physical properties of any material. The radiation damage level in W is low compared to ferritic steel - a remarkable feature for tungsten. For ARIES-ACT operating conditions, transmutation of W does not appear to present a significant issue.
