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 electrolysis process is essential in the water detritiation subsystem using the combined electrolytic catalytic exchange process. A special experimental program was designed to characterize a modified HOGEN H Series industrial electrolyzer. The tritium amount transferred to hydrogen gas, the water enrichment factor, and the number of hours necessary to attain a steady-state regime were parameters of primary interest in the experiments. To minimize the necessary time for a steady-state regime, the holdup of the water electrolyzer was chosen as the minimum value allowed for safe and constant parameter operation in all experiments. The stationary regime was attained after 120 h, with an enrichment factor near 5, and an amount of 18% to 19% of tritium transferred from tritium-enriched water to hydrogen gas. These parameters were obtained in all three experiments, and the modeling software of isotope separation by electrolysis confirmed the results.
