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.

As suggested by Brissenden, it is possible to analyze the reaction rate in the unresolved resonance region by generating sets of random resonance parameters that have the correct statistical properties. Since each set of parameters is itself a random variable, an estimate of the probable error in an average-group cross section or reaction rate can be made by averaging over many random sets. This we have done for a mixture representative of fast breeder reactors and for the energy range 700 to 900 eV. This region is a typical one for studying the Doppler effect. If we make the assumption (a great oversimplification) that the response in this small energy band is typical, not only for the mean but also for the variance, then we would conclude that, if all fine groups (of width 200 eV) have the same weight, the probable error in the fissile component of the Doppler coefficient is about equal to its mean value. For the fine group itself, the probable error in the difference in the relative changes of the fission and the absorption rates is about ten times the mean value.
