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.

External current drive (CD) is an important prerequisite for the control of the plasma current profile in advanced tokamak scenarios as well as for the development of quasi-stationary, fully noninductivly driven tokamak discharges. On ASDEX Upgrade, three heating systems, neutral beam injection, ion cyclotron resonance heating, and electron cyclotron resonance heating, are available for this purpose. The status of CD modeling and the CD capability of these systems are reviewed, and a brief overview is provided of what has been achieved experimentally with respect to CD in various discharge scenarios.
