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.

A pilot rig for a preparative gas chromatograph is described. In order to increase the volume of the samples to be separated different separation columns were investigated. The pilot plant is designed as to operate also with two columns at the same time. To recover the separated H isotopes the pilot rig was equipped with three uranium getters which can be automatically switched to the separation columns by electropneumatic valves. These valves are actuated in response to a detector signal. The maximum sample volume achieved with one separation column is 600 ml (STP) of a three-component mixture (H2, HD and D2) with a purity of 98.5 - 98.7% and even 1000 ml (same mixture) with a 91% purity with respect to the components H2/HD.
