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 deuterium exchange reaction between water vapor and hydrogen gas is studied at 1 atm total pressure and temperatures from 150 to 250°C using a commercially available platinum-impregnated alumina catalyst. Below a water vapor pressure of 190 Torr, two reaction processes, an external mass transfer of hydrogen and an adsorption of water vapor on the surface of the catalyst, are involved in the rate limiting transfer step. Above 190 Torr, external mass transfer of hydrogen governs the reaction rate. An activation energy of 1.5 ± 0.6 kJ/mol is obtained for this transfer step.
