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.

An experimental method of measuring epithermal-neutron spectra by use of resonance activation detectors is presented. Measurements of the change in cadmium ratio with varying dilutions of the same isotope are related to the self-screening properties of selected neutron resonances. The neutron spectra obtained in this way are compared with time-of-flight measurements. A wide range of 235U- or 233U-fueled, BeO-moderated substitution lattices were studied. Marked deviation from the 1/E distribution of the epithermal spectrum was observed for lattices in which the fuel-to-moderator ratio exceeded 1:2000.
