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.

Proceedings | 16th International High-Level Radioactive Waste Management Conference (IHLRWM 2017) | Charlotte, NC, April 9-13, 2017 | Pages 14-19
Many countries have separate regulations for used nuclear fuel (UNF) and high-level radioactive waste (HLW) storage, transportation, recycling, and disposal. In general, each regulation sets a maximum annual dose or health risk just for that waste management component (storage, transportation, or disposal). In addition to dose or health risk limits, many of the regulations either specifically require or recommend that the health risk to members of the public be kept As Low As Reasonably Achievable (ALARA) using Best Available Technology (BAT). Again, ALARA and BAT requirements are to be applied only to the system that it is subject to the regulation. This paper provides some examples of the impacts of health risk from the entire back end of the fuel cycle from attempts to minimize risk from just one part of the back end of the fuel cycle. With separate regulations that minimize individual dose rates for storage, transportation, and disposal, the overall health risk from the back end of the fuel cycle may not be minimized. This calls into the question whether ALARA and BAT concepts should be part of compliance.
