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.

An integral benchmark experiment on the Lithium Fluoride (LiF) material has been carried out in order to check the accuracy of neutronic design calculations. Experimental data of the tritium production rate and the radiation heating rate have been measured directly by each technique using Lithium Carbonate (Li2CO3) pellets and LiF thermo-luminescent dosimeters (LiF-TLDs), and indirectly by the multi-activation foil technique. The present accuracies of the neutronic calculations on the tritium breeding and the nuclear heating are discussed through comparing these benchmark data, where the two-dimensional transport code DOT 3.5 and the ENDF/B-IV cross-section library are applied as a typical example.
