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.

The importance of measuring dimensions from neutron radiographs of nuclear reactor fuel is explained. Measurements are taken using either a profile projector or a traveling microdensitometer. Neutron radiographs are made by the direct, transfer, and track-etch techniques, the last two being used for radioactive objects such as spent reactor fuel. The accuracy of these measurements was investigated during the Euratom Neutron Radiography Working Group Test Program. Measuring results are discussed for different kinds of nuclear fuel pin dimensions and 30 different combinations of recording materials. The accuracy of the measurements is assessed by calculating standard deviations between the dimensions determined from neutron radiographs and the true dimensions of a calibration fuel pin.
