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.

Passive diffusion samplers (PDS) composed of a vial with a solution of distilled water and ethylene glycol have an affinity to capture tritium oxide (tritiated water vapour, HTO) from surrounding air through an orifice in a lid. In order to ascertain the effectiveness of such samplers for tracking changes in the HTO air concentrations attributable to variations in tritium emission rates, the Canadian Nuclear Safety Commission (CNSC) measured the HTO concentrations in air for one year on a bi-weekly basis at various distances along four directions from an operating radioluminescent light manufacturing facility. The collected data demonstrate that the PDS are low cost and low maintenance means for reliable monitoring of airborne HTO emissions. The data indicate a rapid decrease of atmospheric HTO concentrations with increasing distance from the facility in all directions. A strong correlation (r=0.89) was found between reported releases of HTO from the facility and the HTO air concentrations observed at the monitoring locations. Distribution of HTO around the facility correlated strongly (r=0.99) with local wind distribution.
