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.

Presently there exist no experimental methods readily available to characterize the comprehensive motion of wire-wrapped pins for the purpose of measuring fluid structure interactions. Specifically, the dearth of capabilities lies in the need to capture pin-to-pin interactions within the bundle that do not have visual access. This study leverages recent previous efforts that have demonstrated the successful use of a distributed strain sensor to characterize the motion of a single wire-wrapped pin under fluid flow and expands through the use of multiple instrumented pins to characterize the simultaneous motion of pin-to-pin interaction. The outcome of this study demonstrates the direct measurement of pin-to-pin contact, rubbing, and interaction over a range of relevant flow rates on a 19-pin wire-wrapped bundle.
