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.

An integrated analysis of Mark-I liner attack in a postulated core-melt accident is presented. The approach consists of the mechanistic treatment of the sequence of physical phenomena that lead to liner contact by corium debris and their coupling through a probabilistic framework that allows representation of uncertainties. A physically consistent treatment in each sequence is emphasized, but qualitatively different scenarios to represent the range of behavior due to model uncertainties are allowed. The results are presented in a format that allows their direct use in probabilistic risk assessments; in particular, expert opinion is incorporated by a new methodological approach that involves expert review of, and comment on, a fully documented study all under one cover. The study itself is presented in three parts here; the expert inputs can be found in NUREG/CR-5423.
