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.

CVD-tungsten coated Divertor Mock-UPS were fabricated and tested in an ion beam test facility in JAERI. The mock-up consisted of a 2 mm thick CVD-tungsten on a 30 wt% Cu infiltrated tungsten skeleton heat sink. For the thermal fatigue tests, the heat load of 15 MW/m2, 0.3 s was applied to simulate the bonding interface temperature under a steady heat load of 5 MW/m2. The mock-up successfully endured a heat load of 15 MW/m2, 0.3 s for more than 1000 thermal cycles. No cracks were observed at the bonding interface by optical microscope observation. Screening tests were also performed to evaluate the performance limit of the mock-up. The mock-up endured up to a heat load of 20 MW/m2, 10 s without failure.
