KNOXVILLE—Hypothetical scenario: A nuclear bomb is detonated in one of America’s most populated cities. Just as at a crime scene, the officials need to find the culprit.

Currently, the process of analyzing weapons debris to understand the performance or design of the device is painstakingly slow. But new research to be conducted at the University of Tennessee in Knoxville seeks to improve radiochemistry and nuclear forensics to enhance global security.

The new Radiochemistry Center of Excellence is being established through a $1.2 million grant from the National Nuclear Security Administration for the first year, with the potential for a total of $6 million for five years. The center will focus on research and education to advance UT and NNSA laboratories such as the nearby Y-12 National Security Complex, Los Alamos National Laboratory, and Lawrence Livermore National Laboratory. The center will begin operating immediately.

WASHINGTON, D.C.—Four National Nuclear Security Administration sites—Lawrence Livermore, Los Alamos, and Sandia national laboratories, along with the Y-12 National Security Site—have received a total of 11 of R&D 100 Awards from R&D Magazine. The 2013 awards recognize a variety of technologies created by researchers, scientists, and engineers from throughout the nuclear security enterprise.

“My sincere congratulations to the winners of this year’s R&D 100 Awards,” said Energy Secretary Ernest Moniz. “The scientists and engineers who developed these award-winning technologies at the cutting-edge facilities across our national labs are keeping Americans at the forefront of the innovation community and assuring our nation’s economic competitiveness and national security.” [Read more…]

A Chinese supercomputer has bumped the Titan supercomputer at Oak Ridge National Laboratory from the No. 1 spot on a semiannual ranking of the world’s most powerful supercomputers.

The Tianhe-2, which was developed by China’s National University of Defense Technology, is capable of 33.86 petaflops, or more than 33,000 trillion calculations per second.

Now ranked No. 2, Titan was able to perform 17,000 trillion calculations per second, or 17.59 petaflops, according to the list published in November. [Read more…]

World’s fastest supercomputer at ORNL more about research than rankings

The No. 1 ranking for the new Titan supercomputer, designating it as the most powerful in the world, was clearly appreciated in East Tennessee on Monday.

But even as they celebrated a return to the top spot, scientists at Oak Ridge National Laboratory, where the giant computer is based, said they are focused more on research than rankings.

“We love being No. 1,” said Bronson Messer, acting group leader for scientific computing at the National Center for Computational Science at ORNL. “It’s great recognition. But what really matters is what science will do with the machine.”
