Almost 700 kilograms of highly enriched uranium has been moved from the United Kingdom to the United States, and the material is being securely stored at the Y-12 National Security Complex in Oak Ridge for now, federal officials said.

The National Nuclear Security Administration said this month that the highly enriched uranium, or HEU, will be down-blended later into low enriched uranium for use as nuclear reactor fuel.

“The material was returned to Y-12 for secure storage awaiting future disposition,” the NNSA said in a statement provided Friday by Steven Wyatt of the NNSA Production Office in Oak Ridge.

Wyatt said Y-12 supported the removal effort, which was announced by the NNSA on May 3, through technical oversight and guidance of the processing and packaging of material.

Information International Associates has been awarded a contract to help the U.S. Air Force at two major installations in the United Kingdom through September 2020.

Information International Associates, or IIa, will provide base level human resource system management and base enlisted specialty training management services to the U.S. Air Force at the two sites in the UK, a press release said.

This is the fourth consecutive award of this contract to IIa, the press release said. Since 2003, IIa has provided all personnel, supervision, and other resources at Royal Air Force, or RAF, bases Mildenhall and Lakenheath in Suffolk County, UK, about one hour north of London. Kirk Stoye is responsible for activities at both RAF bases.

Kelly Callison, IIa’s senior vice president of operations, manages the UK contract from IIa’s corporate headquarters in Oak Ridge, Tennessee.

“Under the leadership of Kirk Stoye, our UK employees have consistently received excellent and superior ratings for their performance,” Callison said. “We look forward to continuing our partnership with the USAF for another five years.” [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…]
