Oak Ridge National Laboratory (ORNL) is an American multiprogram science and technology national laboratory managed for the United States Department of Energy (DOE) by UT-Battelle. ORNL is the largest science and energy national laboratory in the Department of Energy system by acreage and by annual budget. ORNL is located in Oak Ridge, Tennessee, near Knoxville. ORNL's scientific programs focus on materials, neutron science, energy, high-performance computing, systems biology and national security. ORNL partners with the state of Tennessee, universities and industries to solve challenges in energy, advanced materials, manufacturing, security and physics. The laboratory is home to several of the world's top supercomputers including the world's second most powerful supercomputer ranked by the TOP500, Titan, and is a leading neutron science and nuclear energy research facility that includes the Spallation Neutron Source and High Flux Isotope Reactor. ORNL hosts the Center for Nanophase Materials Sciences, the BioEnergy Science Center, and the Consortium for Advanced Simulation of Light-Water Reactors. ==Overview== Oak Ridge National Laboratory is managed by UT-Battelle, a limited liability partnership between the University of Tennessee and the Battelle Memorial Institute, formed in 2000 for that purpose.〔(【引用サイトリンク】url=http://www.ut-battelle.org/about.shtml )〕 The annual budget is US$1.65 billion, 80% of which is from the Department of Energy; the remainder is from various sources paying for use of the facilities.〔(【引用サイトリンク】url=http://www.ornl.gov/ornlhome/about.shtml )〕 As of 2012 there are 4,400 staff working at ORNL, 1600 of which are directly conducting research, and an additional 3000 guest researchers annually. There are five campuses on the Department of Energy's Oak Ridge reservation; the National Laboratory, the Y-12 National Security Complex, the East Tennessee Technology Park (formerly the Oak Ridge Gaseous Diffusion Plant), the Oak Ridge Institute for Science and Education, and the developing Oak Ridge Science and Technology Park, although the four other facilities are unrelated to the National Laboratory.〔(【引用サイトリンク】url=http://www.ornl.gov/ornlhome/who_we_are_not.shtml )〕〔(【引用サイトリンク】url=http://energy.gov/em/oak-ridge-site )〕 The total area of the reservation 150 square kilometres (58 sq mi) of which the lab takes up 18 square kilometres (7 sq mi).〔〔(【引用サイトリンク】url=http://science.energy.gov/laboratories/oak-ridge-national-laboratory/ )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Oak Ridge National Laboratory」の詳細全文を読む スポンサード リンク
