My story: Dennis Mosebey—ANS member since 1981
. . . and today.
Mosebey in 1984 . . .
I graduated from high school in 1969. My yearbook says my career ambition was to be a nuclear physicist. This was inspired by a paperback book I read: Men Who Made a New Physics by Barbara Lovett Cline. I enrolled as a physics student at Susquehanna University that fall and graduated four years later. Many job applications were sent out, but I quickly learned in any branch of physics you needed at least a master’s degree and preferably a Ph.D. So, I applied to the Penn State nuclear engineering program as a master’s degree candidate. This would not be nuclear physics, but it would be close enough. To help with expenses, Penn State had quite a few internships with branches of Westinghouse, and mine was a three-month-long stint that summer at the Liquid Metal Fast Breeder Reactor project at Waltz Mill, Pa. My job was to work on expanding the uranium-238 fast fission cross sections into the 20-MeV range. Of course, I had no idea what a cross section was, but my supervisor, Gene Paik, and my office partners, especially Colin Durston, were immensely helpful.
Constellation (Nasdaq: CEG) is the nation’s largest producer of clean, carbon-free energy and a leading supplier of energy products and services to businesses, homes, community aggregations and public sector customers across the continental United States, including three fourths of Fortune 100 companies. With annual output that is nearly 90% carbon-free, our hydro, wind and solar facilities paired with the nation’s largest nuclear fleet have the generating capacity to power the equivalent of 15 million homes, providing about 10% of the nation’s clean energy. We are further accelerating the nation’s transition to a carbon-free future by helping our customers reach their sustainability goals, setting our own ambitious goal of achieving 100% carbon-free generation by 2040, and by investing in promising emerging technologies to eliminate carbon emissions across all sectors of the economy.
