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 CERES collaborative program between the French Atomic Energy Commission (CEA) and the United Kingdom Atomic Energy Agency (UKAEA) was performed in the MINERVE and DIMPLE reactors at Cadarache and Winfrith, respectively. CERES Phase II was devoted to the validation of fission product (FP) poisoning through the reactivity worth measurements of FP samples. This paper describes the oscillation experiment at the center of the MINERVE pressurized water reactor–type test lattice. This experiment is strongly representative of the FP poisoning in light water reactor spent fuels because the separated FP isotope is introduced into real UO2 pellets where 238U/iFP resonance overlap occurs. In order to preserve the experimental results within the International Reactor Physics Experiment Evaluation international database, slight corrections to define a two-dimensional benchmark are presented. The evaluation of experimental uncertainties is detailed. Therefore, the accurate APOLLO2.8 analysis of this benchmark is described, using recent JEFF-3.1.1 and ENDF/B-VII.0 nuclear data files. JEFF-3.1.1 FP worth is particularly satisfactory, except for 153Eu, which is underestimated by 8.1% + 2.6%. The CERES integral measurement data also suggest improvements to 99Tc and 145Nd evaluations in the ENDF/B-VII.0 library.
