The management and operating contractor for the National Nuclear Security Administration's (NNSA) Nevada National Security Site, has been recognized for having one of the cleanest, most fuel-efficient vehicle fleets in the nation.

Competing with more than 38,000 public fleets, National Security Technologies' (NSTec) Fleet, Fuel & Equipment Service operation was rated 4th by the 2015 100 Best Fleets, Green Fleet Awards organization, which tracks and rates the performance of vehicle fleets throughout the continent.

To be recognized for having a top fleet, a company must demonstrate vision, outstanding operations, and strategic planning toward the future environmental role of fleet that other public fleets can emulate; reduction in greenhouse gas emissions, and fleet composition demonstrating a commitment to alternative fuel vehicles such as hybrid vehicles, plug-in electric vehicles and alternative fueled vehicles. Candidates must also demonstrate fleet utilization goals that validate a strong commitment to a “green” approach toward keeping the environment clean.

 NSTec’s fleet is comprised of 960 vehicles, ranging from sedans to large trucks. More than 40 of them are alternative-fueled or plug-in electric vehicles.

“Congratulations all. This is quite an accomplishment!” said Jim McConnell, Assistant Administrator for Safety, Infrastructure and Operations for NNSA.

NNSA BlogSandia National Laboratories post-doctoral fellow Stan Chou demonstrates the reaction of more efficiently catalyzing hydrogen. In this simulation, the color is from dye excited by light and generating electrons for the catalyst molybdenum disulfide to evolve hydrogen.

ALBUQUERQUE, N.M. —Sandia National Laboratories researchers seeking to make hydrogen a less expensive fuel for cars have upgraded a plentiful catalyst nearly as cheap as dirt — molybdenum disulfide, “molly” for short — to stand in for platinum, a rare element with the moonlike price of $1,500 a gram.

Simple Sandia-induced changes take the 37-cents-a-gram molly from being a welterweight outsider in the energy-catalyst field — put crudely, a lazy bum that never amounted to much — to a possible contender with the heavyweight champ.

The catalyst’s action can be triggered by sunlight, which eventually may provide users an off-the-grid means of securing hydrogen fuel.

During a recent visit to the Y-12 National Security Complex, NNSA Uranium Program Manager Tim Driscoll stopped by Building 9204-2E’s new direct canning machine, which allows operators to package enriched uranium material removed from dismantled weapons and ship it directly to the Highly Enriched Uranium Materials Facility for long-term storage. An important element of the Uranium Transformation Strategy at Y-12, shipping directly to HEUMF stops the flow of material into Building 9212, enabling faster inventory reduction and improved safety. Direct canning at Y-12 is estimated to save $20-30 million by 2021, assuming current dismantlement plans.

The hydrogen plasma phase transition experimental team, outside the NIF Control Room

At Lawrence Livermore National Laboratory (LLNL), a National Ignition Facility experimental campaign may have unlocked scientific secrets behind how hydrogen becomes metallic at high pressure.

“Hydrogen properties are still puzzling,” said Lawrence Livermore National Laboratory (LLNL) physicist Marius Millot. “In particular, back in 1935, it was predicted that hydrogen should become metallic at sufficiently high pressure. But, using static compression, our colleagues have yet to find clear evidence for metallization at room temperature.”

The technology is a finalist in the information technology/electrical category. LLNL collaborated on the laser system with Lasertel of Tucson, Arizona.

  Los Alamos National Laboratory
 LARS LARS is a small-scale radiography device that, for the first time, can provide continuous high-speed x-ray imaging of spontaneous dynamic events, such as explosions, reaction-front propagation and material failure. To image these types of events, scientists require the use of some type of penetrating radiography, which LARS provides. Laura Smilowitz, of the Laboratory’s Physical Chemistry and Applied Spectroscopy group, and her team and collaborators at CoRELabs developed this technology.
 PipeLIBS Throughout the world, oil, gas, and petrochemical plants often use vessels and pipes to store or transport fluids. Over time, some of these vessels can corrode because of the caustic nature of the fluids inside them. PipeLIBS (Laser-Induced Breakdown Spectroscopy) is an elemental-analysis system that uses a laser beam to excite material so that it emits light at wavelengths characteristic of its chemical composition; it identifies the target elements and determines their concentration in a matter of seconds or minutes.

Designed for high-performance computers, MDHIM is a revolutionary software tool that performs more than a billion key/value inserts per second that can be retrieved in key order.

Today, scientists analyze data visually, often turning data into images or even movies. Current simulations on high-performance computers, such as supercomputers, make visualizing data untenable because of the resources required to move, search and analyze all the data at once. MDHIM provides a solution to this complicated problem by identifying, retrieving and analyzing smaller subsets of data.


Structural Health Monitoring (SHM) is quickly becoming an essential tool for improving the safety—and efficient maintenance—of critical structures, such as aircraft, pipelines, bridges and dams, buildings and stadiums, pressure vessels, ships, power plants, and mechanical structures such as amusement park rides and wind turbines.

Los Alamos engineers have developed SHMTools, software that provides more than 100 advanced algorithms that can be assembled to quickly prototype and evaluate damage-detection processes. It is a virtual toolbox that can be used to detect damage in various types of structures, from aircraft and buildings to bridges and mechanical infrastructure.

  Nevada National Security Site
 Argus Fisheye Velocimetry ProbeBuilding on technology from the Multiplexed Photonic Doppler Velocimeter, a portable optical velocimetry system that simultaneously measures up to 32 discrete surface velocities onto a single digitizer by multiplexing signals in frequency and time, the Argus Fisheye Probe measures the velocity distribution of an imploding surface along many lines of sight. Laser light, directed and scattered back along each beam on the surface, is collected into the launching fiber. The received light provides a continuous time record. The probe measures surface movement. It is used to better assist scientists in understanding the material behavior in shock physics experiments.
Sandia National Laboratories
LED Pulser

The Sandia LED Pulser uses light-emitting diodes (LEDs) rather than lasers to provide rapidly pulsed, multi-color, very bright light for scientific, industrial, or commercial uses, and can be used in applications formerly possible only with far more expensive light sources. Using custom electronic circuitry, it drives high-power LEDs to generate light pulses with shorter duration, higher repetition frequency, and higher intensity than do commercial off-the-shelf LED drivers. The Pulser already has been used in several research studies that helped design and optimize cleaner and more efficient engines, which could, in turn improve local air quality and public health.
