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 Fuel cleanup system (FCU) that recovers fusion fuel (tritium and deuterium) from plasma exhaust mixture gas has been developed and demonstrated at the Tritium Process Laboratory (TPL) of Japan Atomic Energy Research Institute (JAERI). We have proposed a new closed loop FCU system built up by connecting the tubular reservoir tank, the electrolytic reactor and a palladium diffuser. In the electrolytic reactor, methane and water are converted at the same time by electrochemical reaction in gas phase oxidation and reduction to liberate hydrogen isotope as a form of elemental hydrogen. The long tubular reservoir tank that is designed to store and transfer the products gas in plug flow prevents from mixing with reactants for the successive repeat processing. With this tank, high overall decontamination factor of system can be obtained by small number of circulation. As the demonstration test, mixture gas consist of hydrogen isotopes, methane and He were processed in the closed loop FCU. The electrolytic reactor and the tubular reservoir tank worked as designed successfully, and the entire loop exhibited efficient impurity processing performance. The concentration of methane was observed to decrease sharply in every processing by the electrolytic reactor from 2.3% to less than 12ppm finally.
