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 transport of tritium in liquid Pb-17Li has been investigated for different types of capsules and different methods of tritium extraction. Equations describing the tritium release process have been set up and solved, and time-dependent expressions of the outcoming tritium flux have been derived for closed capsules containing stagnant or moving Pb-17Li and for capsules where a He + 0.1% H2 flush gas sweeps the gas phase above the liquid Pb-17Li or bubbles through it. The analytical expressions of the outcoming tritium fluxes depend on tritium diffusivities and solubilities in Pb-17Li and in the container material and on the tritium generation rate in Pb-17Li. The models allow the determination of the characteristic tritium release times when these input parameters are available. The parameters, on the other hand, can be determined by fitting the experimental tritium release data with the theoretical flux equations. The characteristic tritium release time (time to reach 63.2% of the steady state tritium flux) is 14000 s, 7200 s, 2000 s and less than 100 s for the closed stagnant, closed convective, swept and bubbled capsule, respectively, and for the specific conditions of the “Libretto” experiment (Petten - NL).
