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 radionuclides in the gaseous effluent, in the water coolant from the research reactor, and in the surroundings were detected with gamma-ray spectrometry with and without using the Compton suppression technique, depending on the activity levels detected. All gamma-ray spectra were taken at various reactor power levels to investigate the relationship between the gamma-ray activities and the power levels. The linear proportionality between the activities and the power levels is valid to a certain extent. Activity in the water coolant was quite high, so in situ measurement was replaced by the sampling technique. The radionuclide 24Na in the coolant was specifically determined as a function of reactor operating time, and it tended to saturate over time. No manmade radionuclides were present in the surroundings except for 137Cs as fallout.
