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.

Thomson scattering (TS) is one of the most reliable diagnostics to measure the electron temperature and electron density radial profiles in fusion plasmas. In GAMMA 10, a yttrium-aluminum-garnet (YAG)-TS system was constructed with the large solid angle of TS collection optics. We carried out Rayleigh and Raman scattering experiments for system settings and density calibration. We applied the YAG-TS system to the GAMMA 10 plasma. We can successfully measure the radial profiles of electron temperature and density in the central cell of GAMMA 10 by using the YAG-TS system in a single plasma shot. Moreover, in order to increase the TS signal intensities, we have constructed a multipass TS system of the polarization-based system with image relaying optics. Clear TS signals from first to fourth passing lasers through the GAMMA 10 plasma were obtained. The obtained TS signal intensity was about three times larger by first to fourth passing lasers through the plasma than that of the first pass.
