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 operator decision aid (IODA) system utilizing computers and cathode-ray tube (CRT) display devices has been developed by focusing attention on the importance of the operator’s role in a nuclear power plant. The developmental objective of this IODA is to improve safety, reliability, and the quality of nuclear power plant operation by helping operators handle abnormal plant conditions. Three support functions corresponding to the respective roles of operators are determined and developed: (a) a standby systems management function, (b) a disturbance analysis function for monitoring plant status and diagnosing disturbances, and (c) a posttrip operational guidance function for providing symptom-based operational guidance after a reactor scram. These functions have been integrated into an operator decision aid system for abnormal conditions in boiling water reactor (BWR) power plants. Information on plant diagnosis and guidance messages are provided through a three-level hierarchical structure of CRT display images. Results of functional verification tests of IODA using a BWR simulator show that the system effectively supports operators at all stages—from normal operation of the plant to safe plant shutdown after a reactor scram. The IODA can help operators quickly and easily understand a plant situation and take appropriate measures during abnormalities. It will also alleviate the burden on operators, thus reducing the potential for judgmental and operational errors in various plant operating modes.
