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.

Gas discharge plasma targets were used for energy loss and charge state measurements of fast heavy ions 5 MeV/u ≤ Ekin ≤ 10 MeV/u in a regime of electron density and temperature up to 1019 cm−3 and 20 eV, respectively. Progress has been achieved in the understanding of charge exchange processes in fully ionized hydrogen plasma. An improved model that has taken excitation-autoionization processes into account has removed some of the discrepancies of previous theoretical descriptions. Furthermore, the energy loss of the ion beam serves as an excellent diagnostic tool for measuring the electron density in partially ionized plasmas such as argon. The experience with these methods will be used in the future to diagnose dense laser-produced plasmas. A setup with a 5-GW neodymium-glass laser, currently under construction, will provide access to density ranges up to 1021 cm−3 and temperatures > 100 eV.
