We are delighted to announce two key personnel changes.

Jay TildenMr. Jay Tilden has officially been appointed as the Associate Administrator for Counterterrorism and Counterproliferation.  Jay has been the Acting Associate Administrator since Steve Aoki’s departure at the end of last year.  As you know, the mission of Counterterrorism and Counterproliferation is to prepare for, respond to, and successfully resolve nuclear and radiological accidents and incidents worldwide.

Jay brings significant experience and expertise to this mission.  Previously, he served as the Deputy Associate Administrator for the same office.  He also has been the Director of the Office of Nuclear Threat Science (formerly the Office of Nuclear Counterterrorism); the Intelligence and Security Advisor to the Deputy Under Secretary for Counterterrorism; director of the Counterterrorism Division (CTD) within the Energy Department’s Office of Intelligence and Counterintelligence; and an intelligence and program analyst for the Office of Security Policy advising on Design Basis Threat policies for the Department.  Jay is a retired U.S. Army Chief Warrant Officer and served in both active and reserve capacities including Desert Shield/Desert Storm and Enduring Freedom/Noble Eagle.  He graduated from the University of Maryland and completed post-graduate studies in strategic intelligence from DIA’s Joint Military Intelligence College.

Dr. Dave Bowman has been named permanent Deputy Associate Administrator for Counterterrorism & Counterproliferation.  Dave has been the Acting Deputy since the beginning of the year.  Dave previously served as the Director for the DOE/NNSA Office of Nuclear Incident Response.  This Office is responsible for staffing, training, equipping, and exercising the Department’s response teams in the areas of nuclear/radiological search, render safe, and consequence management.  From 2009-2011, Dave was the Deputy Director for the Office and he served as the DOE/NNSA Consequence Management Program Manager from 2005-2009.  Prior to his employment at DOE Headquarters, he was a radiological emergency responder, senior scientist, and project manager at the Remote Sensing Laboratories in Las Vegas, Nevada, and at Joint Base Andrews in Maryland.  Dr. Bowman received a Ph.D. in Nuclear Chemistry from the University of California at Berkeley and is recognized by the American Academy of Health Physicists as a Certified Health Physicist.

We congratulate both Jay and Dave on their new appointments and look forward to their contributions to NNSA for years to come.

“Mission First, People Always”

Y-12 recently recognized 29 inventors at their annual Tech Transfer award ceremony. The group was awarded 13 patents and submitted more than 30 invention disclosures in the past year.

OAK RIDGE, Tennessee – Twenty-nine Y‑12 inventors were recognized for their technology and innovative accomplishments during the recent 12th annual Technology Transfer Awards Ceremony. The site has a long history of producing technologies initially used at Y-12 and later transferred to the private sector.

Thirteen patents were awarded in FY15 in areas ranging from a wireless sensor for detecting chemical compounds to an apparatus for safeguarding a radiological source. 

The inventors also were recognized for bringing forward new ideas in the form of invention disclosures that could one day lead to future patents. These employees were acknowledged for both their creativity and innovative ideas in support of the technology development and transfer mission. The new inventions developed by the honorees will be used to further Y-12’s mission work and will be made available to license to benefit the public through Y-12’s Technology Transfer program.

Modeling and optimization tools created by NNSA’s Sandia National Laboratories are helping the U.S. Marine Corps use renewable-energy technologies in operations at home and in the field. The Marine Corps recently worked with the the lab to further develop Sandia’s Microgrid Design Toolkit to give military decision makers support and information needed to pursue sustainability goals.

The goal of the project is to help the Marines create microgrids – localized grids that generate and consume power and can run either independently or connected to the larger utility grid. Microgrids enable Marines to power up securely without plugging into utilities. Eventually, the Marine Corps intends to use microgrids to achieve completely reliable and cost-effective energy independence.

The toolkit presents microgrid designers with information about technology options to support smart decisions about technology solutions early in the design process. The software uses powerful search algorithms to identify potential trade-offs among factors such as cost, performance and reliability. A beta version of the toolkit is available for public download.

The new project between Sandia and the Marines is one example of the nationwide effort to accelerate joint efforts in clean energy and national energy security technologies from national laboratories to military end users.

The Trinity supercomputer at Los Alamos National Laboratory.

In a recent paper published in Nature Communications, NNSA researchers at Los Alamos National Laboratory (LANL) recently demonstrated ways to accelerate materials science.

Why is this innovation so noteworthy to NNSA’s mission, as well as other applications? A chef inventing a new dish might test hundreds, even thousands, of ingredient combinations to get a recipe just right. Materials science—vital to keeping the U.S. nuclear stockpile safe, secure and effective—traditionally has worked the same way. Through trial and error, scientists make educated guesses about how a “recipe” for a new material will turn out, based on the known properties its ingredients. LANL researchers have described how they can supercharge the trial-and-error process by teaching a computer to learn and adapt as it virtually combines ingredients. Using adaptive design strategy, based in information science and fed by data from past experiments, the researchers can accelerate the discovery of new materials with desired properties.

“What we’ve done is show that, starting with a relatively small data set of well-controlled experiments, it is possible to iteratively guide subsequent experiments toward finding the material with the desired target,” said Turab Lookman, a physicist and materials scientist in the Physics of Condensed Matter and Complex Systems group at Los Alamos National Laboratory.

“With increasing chemical complexity, the combination possibilities become too large for trial-and-error approaches to be practical,” Lookman said. “The goal is to cut in half the time and cost of bringing materials to market.”

The White House’s Materials Genome Initiative spurred interest in accelerated materials discovery, and the LANL study is one of the first to demonstrate how machine learning can actually lead to the discovery of new materials.

Fire whirls from a 3-meter diameter pool in the Thermal Test Complex at Sandia National Laboratories.NNSA’s laboratories need to conduct a lot of tests under extreme conditions. From enormous implosion pressure to energy more intense than the sun, NNSA’s labs support national security by verifying the U.S. nuclear weapons stockpile without underground explosive testing.

In Sandia National Laboratories’ Thermal Test Complex  in Albuquerque, a controlled environment provides a way to demonstrate the performance of components and assemblies under a variety of abnormal thermal environments and is an ideal setting on which to develop and validate response models. Researchers focus on fires that rotate since “fire tornados” generate much higher heat fluxes than non-rotational fires.

In a recent test, cameras caught a climbing funnel of rushing flames that towered almost to the roof of the 50-foot-tall building housing the test enclosure. To “turn off” the fire tornado, operators simply flip a safety switch to shut down the 750-horsepower fan that sucks outside air and cut the supply of fuel.

“One objective of the current experiments is to create an extremely abnormal thermal environment, representative of what a weapon potentially could be exposed to,” said test director Anay Luketa. “The current tests control boundary conditions and offer repeatable experiments.”

The TTC complex, completed in 2006, centralizes Sandia’s thermal test capabilities, incorporates multiple unique design features and provides advanced capabilities for thermal testing found nowhere else in the world.
