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.

To efficiently confine the gaseous deuterium and tritium, which are the important fuels in the development of fusion energies, China has developed a series of hydrogen resistant stainless steels, named as the HR series of stainless steels. The mechanisms of the interactions between tritium with the decayed helium-3 and these stainless steels were investigated by theoretical calculations, experimental observations or tests through gaseous tritium loading into the stainless steels and years of storage. Results showed that the China made HR stainless steels had good performance to resist hydrogen damage or hydrogen embrittlement. They are the ideal structure materials for tritium systems used in a fusion reactor like ITER. Nevertheless, tritium permeation at high temperatures are still high. Tritium permeation barriers with the aluminides on the surface of the components were successfully developed, which could greatly reduce tritium permeation flux down to 2~3 orders of magnitudes.
