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.

For more than 40 years, large volume calorimeters developed by SETARAM Instrumentation, have been used for nuclear applications including the assay of tritium and plutonium. They have been installed in major nuclear centers all around the world.The calorimeters are used for inventory of nuclear material, or for research. In 2011 a project was launched to develop a calorimeter for the management of waste in large volume drums. A new calorimeter has been developed by Setaram Instrumentation and the CEA Valduc in France.This new calorimeter is designed for drums having a volume bigger than 100L. It guarantees high operator safety by optimizing drum handling and air circulation for cooling, and optimized software for direct measurement of the quantity of nuclear material. The system is designed to provide precise measurements independent of environmental conditions.
