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.

The analysis of Faraday rotation measurements shows that the safety factor on the magnetic axis stays well below one during the full sawtooth cycle.The current density profile has a unique shape during the sawtoothing plateau phase of ohmic discharges, independent of plasma current and magnetic field, when it is plotted in suitable normalized coordinates.The observation of short lasting spikes on the Faraday rotation signals can be interpreted as the formation of a transient current sheet during the sawtooth crash.Direct measurements of the magnetic amplitude of the internal kink mode with a fast polarimeter channel show that the displacement of the core because of the growing precursor mode stays much smaller than the q = 1 radius just prior to the sawtooth collapse.The versatile neutral beam heating system on Tokamak EXperiment for Technology Oriented Research (TEXTOR) allows the study of the influence of the plasma rotation on the sawtooth period, which has a minimum when the magnetohydrodynamic rotation in the tokamak frame is stopped.
