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.

Possible excitation of thermonuclear cone instabilities caused by anisotropy in alpha-particle velocity distribution is considered in tokamak reactor plasmas for frequencies much lower than electron cyclotron frequency. In the ignited tokamak reactor experiment, for example the International Thermonuclear Experimental Reactor (ITER), Alfvén waves are excited at frequencies comparable to alpha-particle cyclotron frequency. The growth rate, the region of instability localization in the plasma cross section, and the marginal stability boundaries in the n-T plane are determined for cone Alfvén wave instability.
