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 separation of hydrogen isotopes is an essential element for tritium processing systems. A new process invented at the Savannah River Site, has been developed at Valduc facility: Thermal Cycling Absorption Process. This system uses palladium packed in a column to absorb a stream of hydrogen isotopes. By repeated heating and cooling cycles, the hydrogen isotopes successively desorb into a capacity and go back onto the column. The thermal cycling creates differences in the Pd separation factor for the hydrogen isotopes inducing the concentration of tritium at one end of the column and the concentration of the lighter isotopes at the other end. This paper presents experimental results obtained with a full-scale facility which has been installed in a glovebox so as to treat weakly tritiated gases. Experimental data collected on this device working with several isotopic mixtures are presented and compared to simulation results.
