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.

Carbon Sheet Pump(CSP) has been proposed to be installed on the vacuum vessel wall of the Large Helical Device(LHD) in order to reduce the hydrogen recycling and improve the energy confinement.
The CSP of C/C composite with temperature below 200 °C can pump high energy hydrogen particles such as charge exchange fast neutrals by trapping them. The saturated hydrogen particles can be removed simply by heating the carbon sheet above 800 °C. One of the requirement on the CSP design for LHD is that the temperature of the vacuum vessel must be maintained to be below 70 °C to avoid excessive heat flux to the LHD superconducting magnet system.
The first design of CSP for LHD is presented, and a successful demonstration of heating the CSP carried out.
