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 pressurized subcritical facility was constructed with its main pressure vessel directly above a 28-in.-diam (71-cm) fission source plate centered on the top face of the General Electric Nuclear Test Reactor (NTR). The main pressure vessel had an inside diameter of 36 in. and inner length (less head) of 48 in. to accommodate light-water-moderated fuel lattices with a keff 0.98, constructed of low-enrichment oxide fuel rods. Maximum operating conditions for the facility were 540°F at 1050 psig. The system was heated electrically at 110 kW to raise the temperature and at 35 kW to maintain it at 540°F. With the NTR at 30 kW, and with lattice keff8 n/(cm2 sec) at lattice center. The facility has been used to carry out a program of measurements of nuclear reaction rates within H2O-moderated subcritical lattices of plutonium-enriched oxide fuel rods.
