NNSA, in collaboration with the U.S. Air Force Global Strike Command, recently conducted successful surveillance flight tests using a Joint Test Assembly (JTA) of the B61 Mod 7 (B61-7), B61 Mod 11 (B61-11), and the B83 strategic bombs.

“The recent JTA tests demonstrate NNSA’s commitment to ensuring that all weapon systems perform as planned and that systems are safe, secure and effective,” said Brig. Gen. Sandra Finan, NNSA Principal Assistant Deputy Administrator for Military Application. “The strong partnership between NNSA and Department of Defense is a vital part of our commitment to national security.”

A JTA contains instrumentation and sensors that monitor the performance of numerous weapon components during the flight test to determine if the weapon functions as designed. This JTA also included a flight recorder that stored the bomb performance data for the entire test. NNSA uses the data in a model, developed by Sandia National Laboratories, to evaluate the reliability of the bomb.

The NNSA-designed and built JTAs support the Joint Surveillance Flight Test Program between the Department of Defense and the NNSA to simulate the actual weapon configurations utilizing as much war reserve hardware as feasible. The JTAs are designed by Sandia National Laboratories/California. The JTA test components are manufactured at the Kansas City Plant are then assembled at the Pantex Plant in Amarillo, Texas. The NNSA Tonopah Nevada Test Range, where the tests were conducted, is managed by Sandia. JTAs are not capable of nuclear yield, as they contained no nuclear materials.

A B-2A Spirit stealth bomber from the 509th Bomber Wing, operating out of Whiteman Air Force Base, delivered and released the B61-7, B61-11 and B83 JTAs at the NNSA’s Tonopah Test Range in Nevada.

Cutting the ribbon on the expansion of the SERF.

In an effort to process, treat and recycle up to 300,000 gallons of wastewater per day, Los Alamos National Laboratory launched operations at the new expansion of the Sanitary Effluent Reclamation Facility (SERF-E) with a ribbon cutting ceremony earlier this month.

Each year, LANL produces more than a hundred million gallons of effluent from LANL's sanitary wastewater treatment plant. Instead of being discharged into the environment, the plant pipes the water to the SERF, which treats and reuses it in cooling towers to cool the Strategic Computing Complex.

The facility originally was designed to help LANL meet strict Environmental Protection Agency limits on polychlorinated biphenyl (PCB) discharge in wastewater and reduce the Laboratory’s use of potable (drinkable) water.

Dino Herrera, the Deputy Associate Deputy Administrator for Infrastructure and Construction, oversaw the project and complimented the team that planned and constructed the facility.

“The SERF-E project went from start to finish in four years,” he said. “This is a model for how line-item projects should function, and I applaud the project team for such a great effort.”

ChemCam

NASA's Mars rover Curiosity fired its laser for the first time this weekend on Mars, using the beam from a science instrument to interrogate a fist-size rock.

The mission's ChemCam, designed and built at Los Alamos National Laboratory, hit the fist-sized rock with 30 pulses of its laser during a 10-second period. Each pulse delivers more than a million watts of power for about five one-billionths of a second.

More than 357 pounds of food was collected by staff in NNSA's Office of Emergency Operations as part of the 2012 Feds Feed Families campaign. NNSA will continue to host a variety of activities this month to collect food for the campaign. The DOE-wide goal for campaign is to collect 230,000 pounds of non-perishable food items. These items will be donated to local food banks in the D.C. area.

Sandia researchers have developed a cost-effective robotic hand that can be used in disarming improvised explosive devices, or IEDs.

Funded by the Defense Advanced Research Projects Agency, the Sandia Hand project is modular, so different types of fingers can be attached with magnets and quickly plugged into the hand frame. The operator has the flexibility to quickly and easily attach additional fingers or other tools, such as flashlights, screwdrivers or cameras. Modularity also gives the Sandia Hand a unique durability. The fingers are designed to fall off should the operator accidentally run the hand into a wall or another object.

Read about the Sandia Hand project.

In just a few months, the NNSA’s National Security Campus in Kansas City, MO will be complete and ready for move in.

The new smaller, more efficient Kansas City Plant will reduce annual operating costs by $100 million and supports the NNSA vision of a more responsive and cost-effective nuclear security enterprise. As one of the only LEED Gold certified manufacturing campuses, the green facility will also cut energy consumption by 50 percent.

Pantex, West Texas A&M University and Texas Tech University have teamed up to conduct a study on understanding the impact of wind farms on birds of prey in the Texas Panhandle.

The program uses radio transmitters and satellite receivers to track the movements of Swainson’s Hawks. The recovered data will be compared to information gathered after the completion of the Pantex Renewable Energy Project (PREP) this fall to determine if the wind turbines affect the hawks, their environment and their home ranges.

Governors' Liaisons at Joint Base Andrews

NNSA recently hosted a dozen governors' federal liaisons at Joint Base Andrews for a briefing and tour of NNSA Emergency Operations assets and capabilities. In attendance were governors' staff from Alaska, Connecticut, Florida, Kentucky, Maryland, Michigan, New Jersey, New Mexico and Texas and a representative from the National Governors Association Homeland Security Committee staff. Through the display of specialized ground and maritime radiological monitoring assets, NNSA Emergency Operations demonstrated its ability to support states and other federal agencies in preventing radiological and nuclear incidents from occurring domestically.

About the photo:
NNSA Emergency Operations staff demonstrated how its aerial and ground monitoring assets and associated technical expertise manage and coordinate all federal radiological monitoring and assessment activities in response to a domestic radiological or nuclear emergency. Governors' staff commented on how NNSA's Emergency Operations capability extended far beyond its equipment to the high level of technical expertise that their governors could call on for support in making critical public health and safety decisions throughout a radiological or nuclear emergency.

LANL ships TRU waste to WIPP

For the fourth year in a row, Los Alamos National Laboratory’s TRU Waste Program has shipped a record number of transuranic (TRU) waste shipments to the Waste Isolation Pilot Plant (WIPP) near Carlsbad, N.M., for permanent disposal.

LANL’s 172nd shipment of TRU waste this year left Los Alamos bound for WIPP last week. With two months left in the fiscal year, LANL has already surpassed last year’s fiscal year record of 171 shipments. LANL has transported more than 1,000 shipments to WIPP since that facility opened in 1999. 

Read more about the shipments.

Sandia monitors nuclear safety of mission to Mars

A team of Sandia engineers has worked behind the scenes to ensure the smooth launch of the Mars Science Laboratory (MSL).

NASA's $2.5 billion MSL rover, the largest and most sophisticated vehicle to visit Mars, is powered by a multi-mission radioisotope thermoelectric generator, or MMRTG. The generator uses heat from the decay of 10.6 pounds of plutonium dioxide into 110 watts of electricity to move the rover and run a suite of 10 instruments, which can do things like find water 32 feet below the surface and analyze chemical composition of rocks three car-lengths away.

While the MMRTG significantly increases the rover's range and lifetime from previous rovers, which relied on solar panels, launching nuclear material requires diligent attention to safety, and Sandia has been tasked with conducting the safety analysis report.
