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 European strategy envisages at least one major plasma device between the present generation machines such as JET and the Fusion Demonstration Reactor (DEMO). The European Community has decided to start the definition of this device, designated NET (Next European Torus), to be the focal point and to provide guidance for the current fusion effort particularly the technology programme. NET aims to produce a plasma with reactor-like parameters (i.e. full ignition, extended burn pulse and adequate power density) and with machine parameters and configuration which could be safely extrapolated to DEMO. As far as possible, NET will adopt reactor relevant technologies and be capable of performing engineering testing for the development of the DEMO blanket/first wall. The essential objectives of the programme can be achieved after three quarters of a full power year but provisions are made for continuing the operation up to almost three full power years. A reference parameter set is now being defined together with the main options for the configuration and the principal components. Present uncertainties in the physics data base are leading us to choose a set of parameters which offer considerable safety margins in the physics but, the configuration is being simultaneously optimized for maximum compactness. The degree of extrapolation in scale, performance and operating conditions from NET to DEMO appears to be acceptable. However, the DEMO should operate as a Component Test Reactor to complete the development of nuclear components capable of withstanding high neutron fluence. The definition of the reference parameter set will be followed by the predesign of NET and an associated Technology Programme oriented towards the needs of the device will be implemented; in 1988 the data base on physics and technology should be sufficient to enter into the detailed design leading to a decision on construction in 1992.
