Empowering the next generation: ANS’s newest book focuses on careers in nuclear energy
A new career guide for the nuclear energy industry is now available: The Nuclear Empowered Workforce by Earnestine Johnson. Drawing on more than 30 years of experience across 16 nuclear facilities, Johnson offers a practical, insightful look into some of the many career paths available in commercial nuclear power. To mark the release, Johnson sat down with Nuclear News for a wide-ranging conversation about her career, her motivation for writing the book, and her advice for the next generation of nuclear professionals.
When Johnson began her career at engineering services company Stone & Webster, she entered a field still reeling from the effects of the Three Mile Island incident in 1979, nearly 15 years earlier. Her hiring cohort was the first group of new engineering graduates the company had brought on since TMI, a reflection of the industry-wide pause in nuclear construction. Her first long-term assignment—at the Millstone site in Waterford, Conn., helping resolve design issues stemming from TMI—marked the beginning of a long and varied career that spanned positions across the country.

Energy relaxation and spatial diffusion of fast alpha particles are incorporated into a multienergy group model which is coupled to a fluid transport code for the thermal plasma species. The multienergy group equations evolve the temporal- and spatial-dependent alpha particle distribution function and thus determine alpha particle heating and loss rates for arbitrary thermalization and diffusion models. The effects of deviations from classical, local thermalization on plasma performance are discussed. It is shown that spatial diffusion can lead to inversion of the fast ion distribution function even if thermalization remains classical. This inversion may drive instabilities and lead to anomalous thermalization. Ripple-induced spatial diffusion of fast alphas is used to illustrate the importance of extending the analysis to include pitch angle dependence.
