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 final drift, compression, and focusing segment of a heavy ion beam (HIB) driven inertial confinement fusion (ICF) reactor delivers the accelerated bunch of ions to the target with the required pulse length and beam spot size, in essence matching the accelerator output parameters to the desired beam parameters at the target. In this paper, we summarize the final drift, compression, and focusing design for the W.J. Shafer Associates (WJSA) Reactor Design Team's OSIRIS1,2 HIB-driven ICF reactor. Our design rearranges the bundle of beams emerging from the linac into two vertical columns, transports each column to a beam compressor, rearranges the columns into large-diameter rings, then focuses each of the beams in the target. Rationale of the design features and description of the beamline elements are given.
