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 notched neutron spectrum filter technique is a method for determining hydrogen content in metals. A modified version of this technique has been proposed and has now been tested with both experiments and calculations. This modified technique takes advantage of the angular dependence of neutrons scattered by hydrogen nuclei to increase the sensitivity of the technique by a factor of ∼ 20. An experimental accuracy of 0. 4 wppm of hydrogen in a typical 0.31-cm-thick steel sample has been obtained. The technique is also applicable to a wide variety of problems where small amounts of hydrogen in, or on, another metal or high atomic number material must be determined.
