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.

An electromagnetic flowmeter (EMFM) has been used in the main cooling loop of the fast reactor, but the large-sized magnet structure of conventional EMFMs was not adopted. Therefore, it is necessary to develop a novel EMFM with small-sized magnets for the fast reactor. But the fear is that the decrease in the magnetic field and the end effect will make the EMFM’s performance worse, though there is no detailed information about the end effect due to such small-sized magnets. This paper describes the EMFM with small-sized magnets for coolant monitoring. By using three-dimensional steady-state electromagnetic analysis, we have studied numerically the end effect of an EMFM with saddle-shaped permanent magnets that are smaller in size than the pipe diameter. Consequently, it has been clarified that the performance of an EMFM can be improved by utilizing the effect of the downstream end of magnets and by combining the inclined electrodes and the effect of the circumferential ends of magnets.
