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.

One of the most important subjects of the GDT research program is MHD-stability and transversal transport of high pressure two-component plasma. Positive influence of radial electric field on the plasma confinement was demonstrated in previous experiments on the GDT in regimes without any special MHD stabilizers. In recent experiments it was observed that stable plasma confinement always corresponds to intermittent distribution of biasing potential on limiters and plasma dumps. It was shown that enhancement of plasma confinement time corresponds to the radial electric field in the range of 15-40 V/cm and one induces the sheared plasma rotation. Regime with grounding of all radial electrodes was typically unstable with plasma confinement time two times lower than gas dynamic flow time. Therefore sheared rotation can stabilize MHD modes of high two-component plasma in the GDT experiment. It is also shown that contact between plasma and radial electrodes is essential but can not completely provide MHD stability in GDT.Measurements using special combined probe were carried out to study fluctuation induced transversal transport and allowed to conclude that cross field transport is negligible and does not play essential role in regimes with sheared plasma rotation.
