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.

Experimental and numerical studies on the flow behavior in a prototypical configuration of spallation targets have been performed, with the main purpose being to support the target design and to assess the computational fluid dynamics application. The effects of flow direction, presence of a perforated plate, and turbulence models on the flow behavior are investigated. Good agreement is obtained between the experimental data and the numerical results, except for the case of downward flow without a perforated plate, where large flow recirculation occurs beneath the window. For the numerical simulation of the flow behavior in the complex target geometries investigated, the shear stress transport model does not show advantages over the k-[curly epsilon] model.
