Energy Economy

Reaffirming America's role as the global engine of scientific discovery and technological innovation has never been more critical. Challenges like climate change, pandemic disease, and resource scarcity demand innovation. Meanwhile, the nation that leads the world in building a clean energy economy that will enjoy a substantial economic and security advantage. That is why the administration is investing heavily in research, improving education in science and math, promoting developments in energy, and expanding international cooperation. This chapter is aimed to provide the introduction of the significant role of STEM education for national security. The chapter will provide an introduction to integrating the awareness training of national security into higher education with the demonstration of the practice of our education module of DHS CFATS in the chemical engineering course of plant safety and security.

At Flamanville, the first generation III reactor in France (EPR) is under the final phase of construction. It is expected that, in the near future, the plant operator (EDF) will send to the Safety Authority the request for the commissioning of this new reactor. Taking into account the difficulties to assess a new evolutionary design in a rather short term, most of the safety related subjects are already under IRSN analysis, in the frame of so called “anticipated examination” of the commissioning request. This “anticipated examination”, which is now in progress, is performed by IRSN by using, both deterministic and probabilistic approaches in a complementary way. In this context, for the analysis of the systems design, IRSN developed a specific analysis guide which allows a comprehensive and systematic analysis of all aspects related to the role of the plats systems in achieving a high level of safety. The paper presents the IRSN approach, as well as the main insights, related to the analysis of the plant systems design as part of the overall plant safety level assessment.

Systematic Framework

In the 1970’s and early 80’s there was a reevaluation of the role of inservice inspection programs. Inservice inspection programs as originally developed under the ASME Section XI Code requirements were based on the best information available at the time and helped establish the safety of the subject components. However, it was determined that the examination requirements were not efficient because examinations were being focused on many welds, components, and systems that are not as important as originally thought when the ASME Section III Classes 1, 2, and 3 categories were developed. It was determined that the appropriate locations were not being inspected and that the most effective types of examinations were not being performed. It was felt that a more optimal inspection approach was needed. This eventually led to the development of the risk-informed inservice inspection (RI-ISI) methodology. RI-ISI provides a structured and systematic framework for allocating inspection resources in a cost-effective manner while improving plant safety. It helps focus inspections where failure mechanisms are likely to be and where enhanced inspections are warranted. This paper examines the foundations for the current RI-ISI initiatives and how the RI-ISI methodology may be used in the future for current and next generation plants.

AbstractWhitehouse adapts insights from evolutionary anthropology to interpret extreme self-sacrifice through the concept of identity fusion. The model neglects the role of normative systems in shaping behaviors, especially in relation to violent extremism. In peaceful groups, increasing fusion will actually decrease extremism. Groups collectively appraise threats and opportunities, actively debate action options, and rarely choose violence toward self or others.

AbstractIntuitions guide decision-making, and looking to the evolutionary history of humans illuminates why some behavioral responses are more intuitive than others. Yet a place remains for cognitive processes to second-guess intuitive responses – that is, to be reflective – and individual differences abound in automatic, intuitive processing as well.
