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.

Systematic parameter studies were implemented to investigate the basic characteristics [plutonium and minor actinide (MA)-burning rate, burnup reactivity loss, Doppler coefficient, sodium void reactivity, maximum linear heat rate, etc.] of plutonium and MA-burning fast reactors and also to clarify the feasibility of such plutonium and MA burner fast reactors. Highly enriched mixed-oxide (MOX) fuels and plutonium fuels without uranium were consideredfor plutonium-burning enhancement. It was found that plutonium consumption rates essentially depend on plutonium enrichment. Both burnup reactivity loss and Doppler coefficient are important criteria for highly enriched MOX fuel cores. Cores without uranium were found to consume the plutonium at a very large burnup rate close to the theoretically maximum value of 110 to 120 kg/TW · h(electric). The introduction of UO2 in an internal blanket is effective in enhancing the Doppler coefficient; it causes a minor increase in the sodium void reactivity in nonuranium cores. The MA transmutation in a fast reactor core has no serious drawbacks in terms of core performance, provided that the homogeneous loading method can be employed with a small fraction of MA fuel (∼5 wt%). Fast reactors have a strong potential for burning plutonium and MA effectively.
