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.

A domestic research program called TECNO_FUS was launched in Spain in 2009 to support technological developments related to a dual-coolant (He/Pb-Li) breeding blanket design concept. One of the goals of the project was the analysis of a suitable power conversion system with an enhanced coupling with the reactor heat sources. Each source has a different thermal level which generates many problems in the coupling.In previous works the authors have explored enhanced power cycles, taken from literature, which solve the differences in the thermal levels of the sources with combined or dual cycles. Although these cycles reach high efficiencies (between 45% and 47%) their layout is very complex and the use of steam is required.In this paper a new power conversion cycle is proposed. It avoids the use of complex layouts, being a variant of the supercritical CO2 Brayton cycle matched to the available thermal sources through an extra recuperator. The basic supercritical CO2 Brayton cycle has been also analyzed for comparison. The new cycle has been optimized so that efficiencies above 47% have been achieved.
