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 evaluation of the electron temperature, density, and plasma potential in a glow cleaning discharge hydrogen plasma in the Novillo tokamak is presented. The objective was to investigate the plasma conditions allowing the removal of impurities from the vacuum vessel, thus avoiding the formation of other chemical compounds that could remain adhered to its inner walls. The discharges were accomplished through two anodes and one cathode within the 0.07 to 0.2-mbar-pressure interval at a power density in the range of 100 to 900 W/m2. The plasma parameters were obtained using Langmuir probes. The results indicated that the electron temperature lay between 3 and 10 eV, the electron density was approximately 108 to 109 cm-3, and the plasma potential was in the 10- to 18-V range. The electron energy was in the range of the dissociation energy for most impurities found in the Novillo tokamak.
