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.

Experiments on induced activities in type 316 stainless steel (SUS316) have been performed to verify an induced activity calculation code system, THIDA, by using the FNS facility. Samples of 10 mm φ × 2 mm t SUS316 were irradiated in three different D-T neutron fields. One sample was positioned at 10 cm from the target without any assembly around it and the other two placed inside the Li2O-C pseudo-spherical blanket assembly. After the irradiation, spectra of gamma-rays emitted from produced activities in each sample were measured by using a 60 cm3 Ge(Li) detector following the cooling times from 10 min. to about one month. The gamma-ray spectra were compared with those calculated by THIDA. All measured total gamma-ray intensities agreed with calculated ones within 15 % except one case. Though there are some disagreements in the individual gamma-ray intensities, the agreements are good as a whole.
