<P> In general, these agencies served to coordinate research and build sites . They generally operated their sites through contractors, however, both private and public (for example, Union Carbide, a private company, ran Oak Ridge National Laboratory for many decades; the University of California, a public educational institution, has run the Los Alamos and Lawrence Livermore laboratories since their inception, and will jointly manage Los Alamos with the private company Bechtel as of its next contract). Funding was received both through these agencies directly, but also from additional outside agencies, such as the Department of Defense . Each branch of the military also maintained its own nuclear - related research agencies (generally related to delivery systems). </P> <P> This table is not comprehensive, as numerous facilities throughout the United States have contributed to its nuclear weapons program . It includes the major sites related to the U.S. weapons program (past and present), their basic site functions, and their current status of activity . Not listed are the many bases and facilities at which nuclear weapons have been deployed . In addition to deploying weapons on its own soil, during the Cold War, the United States also stationed nuclear weapons in 27 foreign countries and territories, including Okinawa (which was US - controlled until 1971,) Japan (during the occupation immediately following World War II), Greenland, Germany, Taiwan, and French Morocco then independent Morocco . </P> <Table> <Tr> <Th> Site name </Th> <Th> Location </Th> <Th> Function </Th> <Th> Status </Th> </Tr> <Tr> <Td> Los Alamos National Laboratory </Td> <Td> Los Alamos, New Mexico </Td> <Td> Research, Design, Pit Production </Td> <Td> Active </Td> </Tr> <Tr> <Td> Lawrence Livermore National Laboratory </Td> <Td> Livermore, California </Td> <Td> Research and design </Td> <Td> Active </Td> </Tr> <Tr> <Td> Sandia National Laboratories </Td> <Td> Livermore, California; Albuquerque, New Mexico </Td> <Td> Research and design </Td> <Td> Active </Td> </Tr> <Tr> <Td> Hanford Site </Td> <Td> Richland, Washington </Td> <Td> Material production (plutonium) </Td> <Td> Not active, in remediation </Td> </Tr> <Tr> <Td> Oak Ridge National Laboratory </Td> <Td> Oak Ridge, Tennessee </Td> <Td> Material production (uranium - 235, fusion fuel), research </Td> <Td> Active to some extent </Td> </Tr> <Tr> <Td> Y - 12 National Security Complex </Td> <Td> Oak Ridge, Tennessee </Td> <Td> Component fabrication, stockpile stewardship, uranium storage </Td> <Td> Active </Td> </Tr> <Tr> <Td> Nevada Test Site </Td> <Td> Near Las Vegas, Nevada </Td> <Td> Nuclear testing and nuclear waste disposal </Td> <Td> Active; no tests since 1992, now engaged in waste disposal </Td> </Tr> <Tr> <Td> Yucca Mountain </Td> <Td> Nevada Test Site </Td> <Td> Waste disposal (primarily power reactor) </Td> <Td> Pending </Td> </Tr> <Tr> <Td> Waste Isolation Pilot Plant </Td> <Td> East of Carlsbad, New Mexico </Td> <Td> Radioactive waste from nuclear weapons production </Td> <Td> Active </Td> </Tr> <Tr> <Td> Pacific Proving Grounds </Td> <Td> Marshall Islands </Td> <Td> Nuclear testing </Td> <Td> Not active, last test in 1962 </Td> </Tr> <Tr> <Td> Rocky Flats Plant </Td> <Td> Near Denver, Colorado </Td> <Td> Components fabrication </Td> <Td> Not active, in remediation </Td> </Tr> <Tr> <Td> Pantex </Td> <Td> Amarillo, Texas </Td> <Td> Weapons assembly, disassembly, pit storage </Td> <Td> Active, esp . disassembly </Td> </Tr> <Tr> <Td> Fernald Site </Td> <Td> Near Cincinnati, Ohio </Td> <Td> Material fabrication (uranium - 235) </Td> <Td> Not active, in remediation </Td> </Tr> <Tr> <Td> Paducah Plant </Td> <Td> Paducah, Kentucky </Td> <Td> Material production (uranium - 235) </Td> <Td> Active (commercial use) </Td> </Tr> <Tr> <Td> Portsmouth Plant </Td> <Td> Near Portsmouth, Ohio </Td> <Td> Material fabrication (uranium - 235) </Td> <Td> Active, (centrifuge), but not for weapons production </Td> </Tr> <Tr> <Td> Kansas City Plant </Td> <Td> Kansas City, Missouri </Td> <Td> Component production </Td> <Td> Active </Td> </Tr> <Tr> <Td> Mound Plant </Td> <Td> Miamisburg, Ohio </Td> <Td> Research, component production, tritium purification </Td> <Td> Not active, in remediation </Td> </Tr> <Tr> <Td> Pinellas Plant </Td> <Td> Largo, Florida </Td> <Td> Manufacture of electrical components </Td> <Td> Active, but not for weapons production </Td> </Tr> <Tr> <Td> Savannah River Site </Td> <Td> Near Aiken, South Carolina </Td> <Td> Material production (plutonium, tritium) </Td> <Td> Active (limited operation), in remediation </Td> </Tr> <Tr> <Td_colspan="4"> </Td> </Tr> </Table> <Tr> <Th> Site name </Th> <Th> Location </Th> <Th> Function </Th> <Th> Status </Th> </Tr>
