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.

Proton therapy in cancer treatment is an important application in nuclear science. As a key component of proton therapy, the patient positioning system (PPS) based on a robotic arm is used in cancer treatment. The PPS delivers the patient to the target position remotely for treatment with high accuracy. As a high safety and stability device in proton therapy, seismic load is one of the relevant accidental events that will affect the structural integrity of the PPS. In this study, a finite element model was built to investigate resistance of the PPS structure against seismic load. Two kinds of analysis methods (equivalent static analysis and response spectrum analysis) were carried out to calculate the displacement and stress fields to check the response of the PPS against the defined seismic load. The results indicated that all the stresses are lower than the permissible limits and the safety requirement.
