Argonne's Energy and Global Security directorate comprises three research divisions—Nuclear Engineering, Global Security Sciences, and Energy Systems, described below.
- The Energy Systems (ES) division conducts applied energy research to strengthen the economy, protect the environment, and enable energy independence and national security. From invention through demonstration, ES actively forms critical alliances with industrial partners, universities, other national laboratories and other Argonne divisions to conduct research, development, and demonstration (RD&D) in a number of areas, including transportation technology and systems, applied materials and advanced manufacturing and systems analysis. ES is home to the Center for Transportation Research (CTR).
- The Global Security Sciences (GSS) division delivers actionable, defensible, and powerful information and technologies to decision makers who impact and shape our global security. Innovative decision support tools (including simulation models), databases, and analytical methodologies are developed and used to provide quantitative information to decision makers in the areas of national and homeland security, infrastructure assurance, emergency preparedness, social dynamics and policy analysis. Research areas include national and homeland security, infrastructure assurance, emergency preparedness, social dynamics and policy analysis.
- The Nuclear Engineering (NE) division's primary mission is to advance the design and operation of nuclear energy systems. NE and its precursors at Argonne have led the development of civilian nuclear power systems since the dawn of the nuclear age. The division conducts analytical and experimental research in nuclear reactor and fuel cycle systems, nuclear nonproliferation and national security and environmental management.
