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.

Verification of safety is a key activity in designing safety critical systems. The objective of safety verification is to avoid unacceptable risk of damage to public health or property or physical injury by any means. To ensure the goals of safety, these systems must reach a safe state for the occurrence of any failure. There is a need to verify the design of such systems to identify and overcome the probable risks, if any. This paper presents a case for safety verification of the main steam system of a nuclear reactor. The technique shown is based on Petri nets, to model and analyze the safety critical computer-based systems for safety verification. The paper further argues that the proposed technique is beneficial in improving faulty design.
