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.

In the design of FED-A, quasi-steady state operation is conceived in which the plasma current is generated by the transformer coil in the burning phase and by the lower hybrid wave in the transformer-recharging phase. A parametric study was made to obtain optimum plasma and wave parameters in the recharging phase. The plasma current saturates when rf wave power increases. In order to avoid a hollow current distribution we should choose the rf power level which gives current saturation. The saturation current level is very sensitive to the width of the wave spectrum, The optimum plasma density and n11 should be determined so that the saturation current reaches to the required level and the efficiency is maximized for a given Δ n11.
