Note: This story was published in the November 21 edition of “EM Update” by the U.S. Department of Energy Office of Environmental Management. EM Update recently spoke with Jay Mullis, the new manager of the Oak Ridge Office of Environmental Management (OREM), about his vision and priorities for the EM program in Oak Ridge.

What are your main priorities going forward as the new manager of OREM?

Overall, I want to ensure our program maintains the momentum we’ve achieved during the past several years. First, it is important for us to continue pushing forward to complete cleanup at the East Tennessee Technology Park (ETTP, also known as the former K-25 site) by 2020. This will facilitate the transfer of the site back to the community so it can be transformed into a vibrant industrial park capable of generating jobs and economic growth for the region. It will also allow our program to shift its focus and resources toward cleanup at two important, active DOE sites: the Y-12 National Security Complex and Oak Ridge National Laboratory (ORNL). Before we finish our cleanup mission at ETTP, we must also fulfill our historic preservation commitments to preserve and celebrate the many achievements that occurred there during the Manhattan Project and Cold War. 

Secondly, it is very important that we begin laying the foundation for our next big challenges at Y-12 and ORNL. That began on November 20, when we broke ground on the new Mercury Treatment Facility at Y-12. This critical piece of infrastructure will provide an important control measure for mercury and opens the door for us to clean and remove mercury contaminated facilities and soils. Additionally, it is crucial to construct another onsite disposal facility that will provide the space necessary for the waste generated by completing cleanup at Y-12 and ORNL. 

Finally, we will continue our focus on eliminating Oak Ridge’s waste inventory. We are making progress packaging and disposing transuranic waste from ORNL with the Waste Isolation Pilot Plant again accepting shipments. We are working to eliminate the remaining portion of the uranium-233 inventory from ORNL to improve safety and significantly reduce security costs.

China has passed the United States in the total number of top ranked supercomputers, and Titan at Oak Ridge National Laboratory has dropped from fourth to fifth on the TOP500 list of the world’s fastest supercomputers.

The TOP500 list is released twice a year, once in June and once in November. It is based on a benchmark test known as Linpack.

Titan at ORNL dropped from third to fourth in June, bumped from the number three spot by the upgraded Piz Daint, a Cray XC50 system installed at the Swiss National Supercomputing Centre. Titan is capable of 17.59 petaflops. A petaflop is one quadrillion calculations per second. That’s 1,000 trillion calculations per second. Piz Daint is capable of 19.59 petaflops.

That power is useful in scientific research. At ORNL, Titan is used for research in areas such as materials science, nuclear energy, combustion, and climate science. ORNL is a U.S. Department of Energy laboratory.

Titan slipped one more spot in this month’s list, from fourth to fifth. It was displaced by the upgraded Gyoukou supercomputer. That is a ZettaScaler-2.2 system capable of 19.14 petaflops and deployed at Japan’s Agency for Marine-Earth Science and Technology, the home of the Earth Simulator. [Read more…]

Geospatial scientists at Oak Ridge National Laboratory have developed a new computing technique to quickly gather data about building structures to help emergency response teams assessing properties that were damaged by hurricanes Harvey and Irma in August and September.

By coupling deep learning with high-performance computing, ORNL collected and extracted building outlines and roadways from high-resolution satellite and aerial images, ORNL said. As hurricanes formed in the Gulf Coast and the Atlantic Ocean, ORNL activated its technique.

“During devastating weather events, it’s difficult and time consuming to assess damage manually,” said ORNL’s Mark Tuttle. “Our method supports emergency response efforts by providing preliminary building structure data—which can be categorized for residential, multi-family and commercial properties—on the county level, and this has been applied for hurricane-impacted areas of Texas, Florida, Puerto Rico, and other U.S. Caribbean territories.” [Read more…]

Researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory are partnering with the City of Oak Ridge to develop UrbanSense, a comprehensive sensor network and real-time visualization platform that helps cities evaluate trends in urban activity.

The project, initiated by ORNL’s Urban Dynamics Institute, centers on addressing cities’ real-world challenges through applied urban science. Oak Ridge is the first city to test the new technology, which uses open-source, anonymous data from virtual and physical sensors.

“Preparing for urban growth and planning for future infrastructure development and resource demands are global problems, but cities need ways to be proactive on a local level,” said UDI Director Budhendra Bhaduri. “Our goal in bringing science to cities is to put the right tools and resources in the hands of city managers and urban planners so that they can assess local impacts and make strategic decisions to get the best return on future investments.”

UDI researchers Teja Kuruganti and Gautam Thakur from ORNL’s Computer Science and Engineering Division are collaborating with Oak Ridge Director of Administrative Services Bruce Applegate on the design and deployment of UrbanSense.

The prototype designed for Oak Ridge monitors population density, traffic flow, and environmental data including air and water quality, with a total of seven sensors to be installed in the city. “The longer they are in place and the more data they collect, the better the city’s sense of its trends will be,” Thakur said.
