Established by Congress in 2000, NNSA is a semi-autonomous agency within the U.S. Department of Energy responsible for enhancing national security through the military application of nuclear science. NNSA maintains and enhances the safety, security, reliability and performance of the U.S. nuclear weapons stockpile without nuclear testing; works to reduce global danger from weapons of mass destruction; provides the U.S. Navy with safe and effective nuclear propulsion; and responds to nuclear and radiological emergencies in the United States and abroad.
NON-NUCLEAR PRODUCTION AND PROCUREMENT
Kansas City Plant (Kansas City, Missouri)
KCP manufactures and procures non-nuclear weapons components, and evaluates and tests these weapons components. KCP has no special nuclear material (SNM).
NUCLEAR DESIGN AND ENGINEERING AND HIGH EXPLOSIVE RESEARCH AND DEVELOPMENT (R&D)
Lawrence Livermore National Laboratory (Livermore, California)
LLNL conducts research, design, and development of nuclear weapons; designs and tests advanced technology concepts; provides safety, security, and reliability assessments and certification of stockpile weapons; conducts plutonium and tritium research and development (R&D); hydrotesting; high-explosives (HE) R&D; and environmental testing. LLNL also currently maintains Category I/II quantities of SNM (special nuclear materials that require the highest level of security).
NUCLEAR DESIGN AND ENGINEERING AND PLUTONIUM
Los Alamos National Laboratory (Los Alamos, New Mexico)
LANL conducts research, design, and development of nuclear weapons; designs and tests advanced technology concepts; provides safety, security, and reliability assessments and certification of stockpile weapons; maintains production capabilities for limited quantities of plutonium components (i.e., pits) for delivery to the stockpile; manufactures nuclear weapon detonators for the stockpile; conducts tritium research and development (R&D), hydrotesting, high explosives (HE) R&D, and environmental testing; and currently maintains Category I/II quantities of SNM (special nuclear materials that require the highest level of security).
HIGH-HAZARD TESTING AND EXPERIMENTATION
Nevada TestSite (65 miles northwestof Las Vegas, Nevada)
NTS continues to maintain the capability to resume underground nuclear testing while conducting hydrotests and high-hazard experiments involving both nuclear material and high explosives. NTS also conducts non-nuclear experiments; performs research and development activities; safeguards Category I/II quantities of SNM (special nuclear materials that require the highest level of security); provides training on nuclear safeguards, criticality safety, and emergency response; and affords the Nation the capability to disposition a damaged nuclear weapon or improvised nuclear device.
ASSEMBLY/DISASSEMBLY AND HIGH EXPLOSIVES (HE)
PRODUCTION & MACHINING
Pantex Plant (Amarillo, Texas)
Pantex dismantles retired weapons; fabricates high-explosive (HE) components and performs HE research and development (R&D); assembles HE, nuclear, and non-nuclear components into nuclear weapons; repairs and modifies weapons; performs non-intrusive pit modification; and evaluates and performs surveillance of weapons. Pantex maintains Category I/II quantities of SNM (special nuclear materials that require the highest level of security) for the weapons program and stores SNM in the form of surplus plutonium pits pending transfer to Savannah River Site for disposition.
NON-NUCLEAR DESIGN AND ENGINEERING AND MAJOR ENVIRONMENTAL TESTING
Sandia National Laboratories(Albuquerque, New Mexico; Livermore, California; and other locations)
SNL conducts systems engineering of nuclear weapons; conducts research, design, and development of non-nuclear components; manufactures non-nuclear weapons components including neutron generators for the stockpile; provides safety, security, and reliability assessments of stockpile weapons; and conducts high-explosives (HE) research and development (R&D) and environmental testing. SNL/New Mexico is currently removing its Category I/II quantities of SNM (special nuclear materials that require the highest level of security) and by the end of 2008 should no longer need Category I/II SNM quantities on a permanent basis. The principal laboratory is located in Albuquerque, New Mexico; a division of the laboratory is located in Livermore, California. Sandia also operates TTR near Tonopah, Nevada, for flight. No Category I/II quantities of SNM are permanently maintained at the TTR, although some test operations have involved SNM.
OPERATIONS INVOLVING LARGE QUANTITIES OF TRITIUM
Savannah RiverSite (Aiken, South Carolina)
SRS extracts tritium and performs loading, unloading, and surveillance of tritium reservoirs. SRS does not maintain Category I/II quantities of SNM (special nuclear materials that require the highest level of security) associated with NNSA weapons activities, but does maintain Category I/II quantities of SNM associated with other Department of Energy activities, such as the Environmental Management program.
URANIUM AND CANNED SUBASSEMBLIES
Y-12 (OAK RIDGE, TENNESSEE)
Y-12 manufactures uranium components for nuclear weapons, cases, and nuclear components comprising canned subassemblies; performs quality evaluation and surveillance activities on subassemblies and components; maintains Category I/II quantities of SNM (special nuclear materials that require the highest level of security); conducts component dismantlement, storage, and disposition of their nuclear materials; and supplies highly enriched uranium for use in naval reactors.
