The U.S. Department of Energy has awarded a $91 million contract to build the Mercury Treatment Facility at the Y-12 National Security Complex.

It’s part of an effort to reduce the amount of mercury in East Fork Poplar Creek and allow the demolition of several large Y-12 buildings where mercury was used to help make nuclear weapons during the Cold War.

The contract, which could be in place for up to four years, was awarded to APTIM-North Wind Construction JV LLC, DOE said Tuesday. [Read more…]

The National Nuclear Security Administration is preparing to restart a program to replace the W78 nuclear warhead, and new facilities at the Y-12 National Security Complex could be important to that project, a federal agency said Friday.

The W78 is one of two types of warheads on U.S. Air Force intercontinental ballistic missiles. The W87 is the other.

Critical components inside the W78 are aging, according to the U.S. Government Accountability Office, which published a report about the warhead replacement program on Friday. Also, the military’s requirements for, among other things, the safety and security features of the warhead have changed since it entered the stockpile in 1979, the GAO said.

Besides being used by the Air Force, the replacement W78 warhead could be used in ballistic missiles launched from Navy submarines, although further studies are required, the GAO said.

The two Y-12 facilities that could affect the warhead replacement program are the Uranium Processing Facility, which is now under construction, and the Lithium Production Facility, which could have a new building through a project that is still in the planning stages. [Read more…]

The Spallation Neutron Source at Oak Ridge National Laboratory has broken a new record by ending its first neutron production cycle in fiscal year 2019 at its design power level of 1.4 megawatts.

Higher power provides more neutrons for researchers who use the facility to study a wide range of materials, an ORNL press release said. The achievement marks a new operational milestone for neutron scattering in the United States and opens the door to studying significantly smaller materials with greater complexity, the press release said.

“The operation of SNS at 1.4 megawatts this cycle has been an outstanding achievement,” said Paul Langan, associate laboratory director for neutron sciences. “It reflects on the maturity of our facility and the high level of technical excellence of our engineering, operational, and scientific staff.”

The power increase was enabled by the combination of extensive improvements to the linear accelerator, including the recent replacement of the radio frequency quadrupole—the first accelerating structure of the accelerator’s frontend assembly, as well as improvements to the liquid mercury target.

Starting in December, Oak Ridge National Laboratory and Y-12 National Security Complex will both manage their own security forces to protect their sites.

Y-12 has been managing its own protective force for about six years, ever since a former contractor, B&W Y-12, terminated a contract with WSI Oak Ridge after a security breach at the 811-acre plant. The current Y-12 contractor, Consolidated Nuclear Security LLC, confirmed this month that it has been responsible for security and security police officers since it began managing and operating the plant in July 2014.

On Friday, UT-Battelle, which manages and operates ORNL for the U.S. Department of Energy, said it is assuming responsibility for providing protective force services at the laboratory starting December 30. That’s when a new security contractor will take over at some federal sites in Oak Ridge.

ORNL Media Relations Manager Morgan McCorkle said about 90 employees who have been providing security services at ORNL under a contract with National Strategic Protective Services LLC will transition from NSPS to UT-Battelle. [Read more…]

Experiments and isotope production have been affected, but employees are still able to carry out their normal duties at the High Flux Isotope Reactor as the U.S. Department of Energy investigates a slightly elevated radiation level in HFIR’s primary cooling system.

The High Flux Isotope Reactor, which is used for research and isotope production, is at Oak Ridge National Laboratory.

In a response to questions on Wednesday, ORNL Communications Director David Keim said the slightly elevated reading in the primary cooling system was well below alarm levels.

“The HFIR operators promptly responded to the reading and placed the reactor in a safe condition,” Keim said. [Read more…]

Seven researchers from the U.S. Department of Energy’s Oak Ridge National Laboratory have been chosen by the Innovative and Novel Computational Impact on Theory and Experiment, also known as INCITE, program to lead scientific investigations that require the nation’s most powerful computers, a press release said.

INCITE awards computing time via a proposal process to researchers seeking to harness the power of DOE computing systems at the Argonne and Oak Ridge Leadership Computing Facilities to solve some of the world’s greatest scientific challenges, the press release said.

Since INCITE’s inception in 2004, the ALCF and OLCF have continuously undergone significant upgrades to retain their edge in facilitating the most computationally demanding scientific projects. The ALCF’s most recent machine is Theta, an 11.69-petaflop Cray XC40 system whose 280,000-plus cores make it ideal for research at the nexus of simulation, data science, and machine learning. An even more powerful system, the exascale Aurora, is planned for deployment in 2021 and is projected to be capable of a quintillion (one billion billion) calculations per second. [Read more…]

The 200-petaflop Summit supercomputer at Oak Ridge National Laboratory stayed at number one on the semiannual TOP500 list of the world’s most powerful supercomputers released Monday.

The Sierra supercomputer at Lawrence Livermore National Laboratory in Livermore, California, climbed to number two from number three. That means the United States now has the top two systems in the world, a position that China held a year ago.

Summit, a water-cooled IBM-built supercomputer, debuted at number one on the TOP500 list in June. That was the first time since 2012 that the United States had the most powerful supercomputer in the world. The earlier top system, Titan, a Cray machine, is also located at ONRL. ORNL and LLNL are both U.S. Department of Energy laboratories.

Officials celebrated the launch of Summit in a ceremony attended by U.S. Energy Secretary Rick Perry on June 8. The supercomputer is capable of 200 petaflops, or 200,000 trillion calculations per second. That makes it about about eight times more powerful than Titan, its predecessor.

Besides being the most powerful, Summit has been described as the world’s smartest supercomputer, a machine that can learn. As big as two tennis courts, Summit has 4,608 compute servers. Each has two 22-core IBM Power9 central processing units (CPUs) and six NVIDIA Tesla V100 graphics processing unit (GPU) accelerators. That’s more than 9,000 conventional processors and nearly 28,000 graphics processors, or about 37,000 total. [Read more…]
