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.

Double-differential cross sections for the production of protons, deuterons, tritons, and alpha particles from a silicon target were determined using fast incident neutrons. The inclusive charged particle emission spectra were measured at six laboratory angles, 20, 40, 60, 70, 110, and 140 deg, over the neutron energy range of 25 to 65 MeV. Representative results are shown for the cross-section differentials in energy and angle as well as for angle-integrated cross sections. The spectra are compared to existing data and with predictions from nuclear model calculations. Since the data for 62.7-MeV incident neutrons are the most complete, we emphasized these results; from the experimental energy-differential cross sections, the total charged particle production cross sections are determined as well as the partial and total kerma coefficients for silicon. Moreover, a comparison is done with our data on aluminum, for which exists a consistent set of measured cross sections in the same neutron energy region.
