Lawrence Livermore National Laboratory has now de-inventoried 97 percent of special nuclear material requiring the highest level of security protection.
The removal is part of NNSA's efforts to consolidate Category I and II special nuclear material, requiring the highest level of security by Oct. 1, 2012. This initiative will further improve security and reduce costs as part of NNSA's overall effort to transform the Cold War era nuclear weapons complex into a 21st century nuclear security enterprise.
All shipments have been completed in full compliance with safety and environmental laws and procedures. All federal and receiver site requirements were met for these shipments. The de-inventory project was initiated in October 2006.
NNSA had originally planned to remove high-security material from Livermore by 2014. However, NNSA developed an accelerated timeline to remove the material safely by Oct.1, 2012.
NNSA’s Global Threat Reduction Initiative (GTRI) was recently commended by the Low-Level Radioactive Waste Forum (LLW Forum) for its efforts to find solutions to the issue of disused and unwanted radioactive sealed sources. Specifically, Abby Cuthbertson of GTRI was recognized for the work she has done, along with the Utah Division of Radiation Control and EnergySolutions, to develop a pathway for secure disposition of certain Class A sealed sources at the Clive low-level radioactive waste disposal facility in Tooele County, Utah.
At the spring meeting of the LLW Forum, a resolution was passed that acknowledged the benefits of sealed sources to society as a whole, the significant national security threat posed by disused sources, and the importance of developing disposal options as a permanent solution to the associated threat. The resolution also expresses appreciation for the coordination and cooperation by GTRI, the State of Utah, and EnergySolutions towards meeting that challenge and contributing to our national security.

B&W Pantex has been named the 2012 Employer of the Year by the Texas Veterans of Foreign Wars for its exemplary efforts to hire and support veterans. Pantex representatives were presented the award last Thursday at the VFW state convention in Addison.
Anthony Acklin, center, B&W Pantex Human Resources Generalist, holds the 2012 Employer of the Year Award with officials from the Texas chapter of the Veterans of Foreign Wars.

Sequoia, a supercomputer built for NNSA, has been named the fastest in the world by Top500. Operating at 16.32 petaflops (quadrillion floating point operations per second), Sequoia helps monitor the nation's nuclear weapons stockpile by simulating weapons performance in high detail. Simulating weapons performances permits NNSA to ensure the safety, reliability and effectiveness of our nuclear weapons without the use of nuclear explosive testing. The IBM BlueGene/Q system is housed at Lawrence Livermore National Laboratory.
The semi-annual Top500 is an industry standard list that was released June 18 at the International Supercomputing Conference (ISC12) in Hamburg, Germany. The last time a supercomputer from the United States placed number one on the list was November 2009.
Sandia recently upgraded the critical assembly (a small nuclear reactor) in Tech Area 5 to permit a new class of experiments as part of the development of a reactor experiments training course for NNSA. Hardware was designed and installed that allows experiments to safely approach critical conditions by varying the amount of water in the assembly. This provides the capability to simulate a critically accident caused by flooding, something that is at the heart of many safety analyses for the storage of nuclear material across the DOE enterprise.

The upgraded hardware (the large black cylinder to the right) that permits criticality experiments by varying the amount of water in the reactor is shown installed on the Sandia critical assembly in Tech Area 5.
Pantex engineers Mitchell Jefferis, from left, and Halianne Crawford help camper Peter Keller with a project at the West Texas A&M University Summer Engineering Camp. Engineers from Pantex are volunteering this week to help out at the camp, which is in its fourth year and hosts students as young as 14 who are interested in engineering.
LANL’s newest facility, the Radiological Laboratory Utility Office Building (RLUOB), is the first to achieve both the Leadership in Energy and Environmental Design (LEED) status and LEED Gold certification from the U.S. Green Building Council (USGBC).
At more than 200,000 square feet, this building is the only radiological facility within the Department of Energy to have attained LEED Gold, which contributes to NNSA's achievement towards the high performance sustainable building goals.
The facility contains laboratories for analytical chemistry and materials characterization of special nuclear material, along with space for offices, training and emergency operations. Its multi-functional purpose makes RLUOB a unique project for which LEED certification was sought.

Work by 90-year-old photographer Ed Westcott, the federal government’s photographer for Oak Ridge during the Manhattan Project, can be seen throughout the walls of Y-12 National Security Complex buildings and in other locations in Oak Ridge. His work is also featured in A Nuclear Family: Y-12 National Security Complex miniseries which aired on East Tennessee PBS.
During the 1940s, Westcott was charged not only with capturing images of government work under way but also with documenting the daily lives of Oak Ridge’s residents. A 20-ft-high by 50-ft-wide mural of a photograph commonly called “Shift Change” covers part of the north wall of Y-12’s cafeteria in Jack Case Center.
The A Nuclear Family miniseries can be viewed online at http://www.y12.doe.gov/about/history/video.php.

Today, the MOX project at the Savannah River Site reached 10 million safe working hours – representative of nearly two years of continuous work during heavy construction without a lost workday.
”The first construction project of its kind in the United States, the MOX project is being executed with precision and safety because of the shared commitment between everyone involved to successfully completing the mission while making safety the first priority,” said Clay Ramsey, NNSA federal project director. “To reach this milestone during such a heightened level of construction is a remarkable achievement.”

The May 2012 NNSA quarterly summary of experiments conducted as part of its science-based stockpile stewardship program is now available here.
The quarterly summary prepared by NNSA’s Office of Defense Programs provides descriptions of key NNSA facilities that conduct stockpile stewardship experiments. These include some of the most sophisticated scientific research facilities in the world including, the Dual Axis Radiographic Hydrodynamic Test (DARHT) facility at Los Alamos National Laboratory, National Ignition Facility (NIF) at Lawrence Livermore National Laboratory, and the Z machine at Sandia National Laboratories. The summary also provides the number of experiments performed at each facility during each quarter of the fiscal year.
The U.S. Stockpile Stewardship Program is a robust program of scientific inquiry used to sustain and assess the nuclear weapons stockpile without the use of underground nuclear tests. The experiments carried out within the program are used in combination with complex computational models and NNSA’s Advanced Simulation and Computing (ASC) Program to assess the safety, security and effectiveness of the stockpile. An extraordinary set of science, technology and engineering (ST&E) facilities have been established in support of the stockpile stewardship program.
