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 KArlsruhe TRItium Neutrino (KATRIN) Experiment aims for the determination of the effective mass of the electron-antineutrino. KATRIN uses a strong, gaseous, windowless tritium source for precision spectroscopy of the β-electrons. The 70-m-long experiment has been set up at the Tritium Laboratory Karlsruhe (TLK) and was commissioned with traces of tritium during two measurement campaigns in 2018. In spring 2019, the first campaign with full source luminosity started. KATRIN uses a complex gas-handling system called Loops for stabilized injection of tritium into the source and tritium gas handling. It also makes use of the unique facilities and possibilities found at the TLK for gas handling, cleanup, and purification. This paper describes the integration of KATRIN into TLK’s existing infrastructure and the current status of the experiment and concludes with a summary of the tritium measurements.
