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 computational system, 2DBCOST, efficiently determines optimum fast reactor fuel management strategies. 2DBCOST, including the associated optimization technique used, provides a basis on which to study the impact of variables such as fabrication, reprocessing, shipping, interest, fuel handling, material costs, inventory lead times, and post-irradiation lag times on reactor fuel costs and to subsequently determine the lowest cost operating policy. The computational system will adjust an LMFBR fuel management policy to meet changing economic or marketplace conditions. Trial use has shown that the code will rapidly determine an optimum fast-reactor blanket fuel management scheme for the cases studied. The impact of both blanket radial out-in subassembly movement and moderator seeding was investigated. Cost penalties associated with moving six sub-assemblies per cycle less than the optimum will approach three million dollars over a 10-year period; similar savings are demonstrated with respect to moderator seeding. The objective function is shown to be unimodal.
