4 Technical leadership In 2009 INL worked closely with the DOEs Office of Nuclear Energy DOE-NE and led a team of national laboratories to develop the Nuclear Energy Research and Development Roadmap. The roadmap serves as a foundation of the Nuclear Energy Research Development and Demonstration RDD program and a balanced plan of research aimed at addressing key challenges to nuclear energy viability. INL input and expertise continue to help DOE-NE develop a research strategy consistent with this roadmap. The Nations Nuclear Energy Lab INL has led a fundamental shift in the DOE approach to nuclear research and development at the Department of Energys national labs universities and within regulatory and policy organizations. The lab is leading an approach that combines physical theory advanced modeling and simulation and small-scale experiments that test fundamental concepts. When engineering-scale irradiation testing or large-scale demonstrations are necessary this approach improves efficiency and reduces uncertainty. LeadershipNuclear Many folks here in Idaho played a key role in helping us shape the objectives on that Nuclear Energy Roadmap. Peter Lyons DOEs assistant secretary for Nuclear Energy From INLs onset the Technical Integration Office TIO concept has helped integrate DOE-NE research across national laboratories universities and industry enabling key linkages to the international research community. Using resident capabilities under three technical integration offices INL emerged as a leader in areas of fuel development separations research and waste form development systems analysis risk and safety analysis and demonstration of reactor and fuel cycle technologies. In FY 2012 DOE expanded the INL technical integration role to include radioisotope power systems and the emerging area of used fuel RDD. This initiative will become increasingly important as industry and regulators examine the technical basis for long-term storage of used fuel and waste confidence. Advanced modeling and simulation In the year since this magazine first described the MOOSE simulation platform Multi-physics Object Oriented Simulation Environment it has gained broad national recognition and a large user base among forefront efforts to develop a massively parallel computational framework. MOOSE has allowed nuclear fuels and materials scientists to develop numerous MOOSE- based applications that predict the behavior of fuels and materials under operating and accident conditions.
