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.

Phase separation in reduced gravity continues to be an obstacle for the National Aeronautics and Space Administrations' power programs. Phase separation would be necessary for the use of a Rankine power conversion cycle in microgravity. The vortex phase separator invented by Texas A&M University may be implemented in a microgravity Rankine cycle for successful phase separation. With the known characteristics of the separator/inventory control system, the Texas A&M University vortex phase separator can be operated successfully for a wide variety of uses in microgravity. The separator operating principle and envelope, test performance data, and inventory monitoring system are described.
