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.

Grain size is one of the most important parameters affecting fission gas release and swelling of nuclear fuels. On the other hand, fission gas bubbles in previously irradiated fuel interact with moving grain boundaries and affect subsequent grain growth. Equations are developed that describe equiaxed grain growth in oxide fuel that has undergone previous irradiation (burnup) at temperatures too low to promote grain growth. The resulting expressions relate the grain growth rate at the new high temperature to the percent burnup (or fission gas content) experienced during the prior low-temperature period.
