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.

Nanosecond bursts of monoenergetic neutrons in the range 0.8–1.6 Mev are injected into non-moderating assemblies of bismuth, lead, and natural uranium. The flux in these assmblies is observed to decay exponentially with characteristic nanosecond time constants in good agree-ment with one velocity transport theory, and the known inelastic scattering and absorption cross sections.These experiments serve as a check on the validity of the assumptions of transport theory. The technique also serves as a method for measuring macroscopic inelastic and absorption cross sections directly, without the necessity of making the corrections required in other methods e.g., for double scattering and for the angular distribution.Nanosecond bursts of monoenergetic neutrons in the range 0.8–1.6 Mev are injected into non-moderating assemblies of bismuth, lead, and natural uranium.
