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 high ion-temperature (> 10 keV) plasma has been performed in ion-cyclotron range of frequency (ICRF) heating experiments on the GAMMA 10 tandem mirror. In such a high performance plasma, low frequency density fluctuations are observed in relation to the applied ICRF powers. A drift-type fluctuation, that is excited when high power ICRFs for the plasma production are applied, is observed in the whole of GAMMA 10 with the finite wave length. The amplitude of the drift-type fluctuation depends strongly on the gas puffing rate, the ICRF antenna configuration and so on. The radial transport of high energy ions due to these fluctuations is studied.
