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.

In order to determine organically bound tritium (OBT) from environmental samples, these must be converted to water, measurable by liquid scintillation counting (LSC). For this purpose we conducted some experiments to determine OBT level of a grass sample collected from an uncontaminated area. The studied grass sample was combusted in a Parr bomb. However usual interfering phenomena were identified: color or chemical quench, chemiluminescence, overlap over tritium spectrum because of other radionuclides presence as impurities (14C from organically compounds, 36Cl as chloride and free chlorine, 40K as potassium cations) and emulsion separation.
The paper summarizes results of physico-chemical analyses of initial combustion water and of purified combustion water using 5 methods (distillation with chemical treatment, lyophilisation, chemical treatment followed by lyophilisation, azeotropic distillation with toluene and treatment with a volcanic tuff followed by lyophilisation), determining the value of pH, conductivity and content of some anions (SO4-2, Cl-, NO3-) and cations (Na+, K+, Ca+2, Mg+2, iron, chromium, nickel and copper). Afterwards, each sample was measured, and OBT measured concentration, together with physico-chemical analysis of the water analyzed, revealed that the most efficient method applied for purification of the combustion water was the method using chemical treatment followed by lyophilisation.
