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.

Formulas are developed for the calculation of the whole-body gamma-radiation dose from a cloud of radioactive gases. The complexity of the formulas is greatly reduced by the simplifying assumption that the cloud does not change in size and shape during the time that the receptor is exposed to radiation. For most cases of interest, the numerical solutions based on this assumption are nearly identical with more detailed solutions. The formulas have been programmed for computer solution so that large parametric studies are possible in an hour or two of machine time. The numerical solutions can be displayed as a contour map or an isometric drawing as a function of cloud size and shape. When lines that are functions of meteorological conditions and distance from the release point of the cloud are added to such a display, the details of the solution are graphically presented to provide a very clear visual comprehension.
