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.

Abstract-Monte Carlo calculations were performed to determine the backscattering from and transmission through concrete of 0.2, 0.5, 1.0, 2.0, 4.0, 6.0, and 10.0 Mev gamma rays. The radiation was assumed to be incident on a semi-infinite medium and on slab thicknesses of 0.5, 1.0, 2.0, and 4.0 mfp at angles of cos00 = 1.0, 0.75, 0.50, 0.25, and 0.10. The case histories of 5000 photons were followed on the IBM 704 digital computer for each of the 175 geometries (874,000 histories). The information obtained included: (1) The characteristics of emergent photons, which were stored on magnetic tape; (2) a routine that processes these characteristics to give polar and azimuthal angular dose distribution; and (3) detailed results from the application of the processing routine to the parameters investigated. The computer program, the processing routine, and the detailed results are given in ref. 1.
