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.

Several filtered-beam facilities exist that provide monoenergetic neutrons at 186 eV; 2, 25, 55, and 144 keV; and at 2.2 MeV. This range of energies can be extended by using natural uranium as a filter in conjunction with suitable secondary filters and scattering foils. The range of energies obtainable with uranium lies between 100 eV and 2.5 keV. Neutron fluence rate and beam purity estimates are provided at the most useful energies obtainable with uranium. Dose equivalent rates and kerma rates are also evaluated, and it is concluded that such a range of filtered beams would have many useful applications in radiation protection.
