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.

Tritium is a fuel and the most mobile and significant radioactive sources for ITER. In the design of TBM tritium systems of China, the safety design of common chemistry engineering system and tritium safety design are considered at the same time. It is necessary to avoid a continuous increase of the tritium concentration in the coolant and to reduce the tritium permeation into the secondary coolant as well as environment. In this paper, the design and tritium permeation analysis of China HCCB TBM port cell are introduced. At first, the primary design considerations of the system are given to fulfill the engineering demand of the ordinary system (non radioactive system). Then the tritium permeation, the release analysis, the effect of tritium release to the people and environment are discussed. From the calculation of the tritium permeation in the systems housed in the port cell, tritium permeation barrier is needed in the higher temperature components such as the reduction bed and the heater.
