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.

Electromagnetic (EM) pumps are a major component in the safe operation of liquid metal–cooled nuclear reactors and can also be used in any other application in which a conductive fluid is being pumped through a system. During the design of an EM pump, it is useful to model its operating characteristics for pump sizing, flow capabilities, and other design checks. The EM pump analysis code known as MATRIX is a prime example of a tool that can be used for such pump modeling. This paper introduces the modernization and capability investigation efforts completed on MATRIX. An output data comparison of the modernized code is made between both the legacy code and the measured EM pump. Further improvement of MATRIX through data analysis and flow correction techniques is explained.
