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.

Spent nuclear fuel (SNF) is presently being stored at reactor sites awaiting shipment offsite. Analyses conducted for the US Department of Energy (DOE) to evaluate potential strategies for removing SNF from reactor sites use detailed, agent-based models of SNF storage and transportation. Often these models include assumptions to facilitate analysis. Some assumptions might rely on expert judgement, and others are implicitly made when analysis is performed. One common, implicit assumption is that there is no preferred time of year to load casks. Another assumption is that operating reactor sites can only load a fixed number of casks per year. An examination of cask loading dates might improve the quality of these and other assumptions and provide further insight into industry practice. Investigators reviewed dates listed in cask registration letters submitted to the US Nuclear Regulatory Commission. The cask loading dates were then evaluated to identify patterns that would shed light on the validity of assumptions. First, the typical number of casks loaded in a campaign was examined. Next, the time between cask loadings was examined. Seasonal variations were evaluated, along with variations that appear to occur as a result of plant outage cycles. Finally, some larger loading campaigns were noted. Loading campaign size and the relationship between loading campaigns and outages followed notable trends. For smaller sites with fewer reactors, a relatively large degree of scheduling flexibility appears to be present. However, for sites having more reactors, less flexibility is observed, and the relationship between outages and dry cask loading is clearly apparent. It is clear that fewer casks are loaded during the spring and fall, when outages are more likely. Furthermore, cask loadings are reduced during the winter months.
