Nuclear News magazine names Quinn Reynolds to 40 Under 40 list. The American Nuclear Society recently named Sargent & Lundy's Quinn Reynolds to its prestigious 40 Under 40 list, recognizing his technical expertise, leadership, and industry impact. ANS publishes the list in its Nuclear News magazine, honoring professionals from academia, government, utilities, vendors, and professional consulting firms. From hundreds of nominations, they select 40 industry leaders every year, noting their potential for future contributions to the nuclear community through influencing policy, engaging with the public, and pushing the field forward.
