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 Coolant Purification System (CPS) together with the Tritium Extraction System (TES) and Helium Cooling System (HCS) are the principal auxiliary circuits of HCLL and HCPB TBMs to be tested in ITER. Among them, CPS is used to extract tritium from the cooling primary circuit as well as to guarantee the removal of gas impurities which could interact with structural material. Based on considerations in terms of safety, tritium accountancy and process control, instrumentation philosophy requires real-time tritium monitoring (which might be not very accurate) to control the processes in both TBM helium loops and special tritium accountancy procedure with regard to the interface with other sub-systems of the Tritium Plant. Furthermore, in addition to chemical speciation of the flow, the control of the process requires the measurement of other parameters such as flow rates, pressures and temperatures. For each monitored parameter, this paper describes the most suitable technologies, including a review of advantages, drawbacks and possible ways of improvement.
