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 scope of this paper is the investigation of the control-strategy-design problem. The digital-control system of a model of a nuclear boiling-water reactor power plant of 500-MW electrical output is considered. The proposed approach, i.e., a system partitioning approach, is applied to the case where there are different kinds of interactions inside the system and where the state-vector representation is used to describe the unsteady states of the reactor. The overall control system is investigated for different sampling periods of digital controllers, and for the case where constraints are imposed on the reactivity controller signals. The influence of the real-noise disturbances upon the overall dynamics of a large power reactor is investigated for the case where the control strategy is determined for the ideal white-noise type of disturbance.
