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 basic parameters characterizing the burn control with the vertical field in an ignited tokamak are discussed in a zero-dimensional model assuming a single circuit for the vertical field and neglecting passive effects. The behavior of the system is determined by three dimensionless quantities: ξ which includes the effect of the mutual inductance; Ũ , related to the gain of the linear feedback; and A, related to the pressure, to the plasma current, and to the vertical field index. Analysis of the circuit equations and of the transport equation leads to the determination of stability regions in the parameter space. It is shown that the effect of the mutual inductance described by ξ is always relevant in the choice of the parameters for a stable burn. As a practical illustration the results are applied to the INTOR case.
