For the U.S. military, accurate weather prediction is vital to both the planning and execution of worldwide missions. To extend its weather modeling capabilities, the U.S. Air Force has joined the computing experts at the U.S. Department of Energy’s Oak Ridge National Laboratory in a strategic collaboration that includes procurement and operation of a new high-performance weather modeling computer system. Key members of the Air Force and ORNL teams, including computing and global security team members, gathered on July 10 to kick off this project and tour the facilities supporting the new system, according to a story posted by ORNL.

The Air Force 557th Weather Wing provides the Air Force and Army with global- and regional-level numerical weather model forecasts. With the increasing scale of the requirements for the new system, the Air Force and ORNL identified an opportunity to take advantage of the capabilities of ORNL’s National Center for Computational Sciences—including expertise in high-performance computing facilities and infrastructure, systems administration, computing procurement and acquisition, and system operations, the story said.

“We learned about the Air Force’s needs, and it was immediately clear that ORNL could help them solve their problems,” said Jim Rogers, NCCS director of computing and facilities. “We can integrate the Air Force weather team’s needs into our facilities in a cost-effective way, leveraging our capabilities to deliver exceedingly high availability to support their mission.” [Read more…]

A company called Qrypt Inc. will incorporate a quantum random number generator developed by Oak Ridge National Laboratory into existing encryption techniques, strengthening cyber security, a press release said.

Qrypt has exclusively licensed the technology from ORNL, a U.S. Department of Energy laboratory. It’s intended to help defend against cyber attacks, including those posed by quantum computing.

Encryption uses codes or mathematical algorithms to make information such as messages or stored data unintelligible to unauthorized readers. Quantum computers make use of the quantum states of electrons or other particles to store and process information as quantum bits.

The press release said Qrypt will incorporate ORNL’s quantum random number generator into the company’s existing encryption platform. It will use inherent quantum randomness to create unique and unpredictable encryption keys enabling virtually impenetrable communications, the press release said. [Read more…]

Federal site cleanup workers reported in August that they had begun removing contaminated sludge and debris from tanks, sumps, and valve boxes at Oak Ridge National Laboratory’s liquid and gaseous waste operations using a powerful, new trailer-mounted vacuum.

The equipment has already enhanced safety and operational efficiency, according to the U.S. Department of Energy Office of Environmental Management.

“Without the vacuum, personnel would be required to fully dress in personal protective equipment and remove the sludge and debris with shovels and buckets,” DOE said. “In addition to being closer to contaminated materials in confined spaces, workers would face an increased chance of slips and falls while climbing in and out of slippery areas in the protective suits.”

Using the vacuum technology has eliminated the risk of heat stress for employees, who would otherwise perform manual labor in protective suits during the hot Tennessee summer, DOE said. [Read more…]

Consolidated Nuclear Security LLC has reached a settlement agreement with federal officials over the improper shipment and storage of classified archived records at the Y-12 National Security Complex in Oak Ridge.

The settlement agreement with the U.S. Department of Energy and National Nuclear Security Administration requires CNS, which manages and operates Y-12, to implement corrective actions and pay a $73,000 monetary remedy.

The settlement agreement was entered into on July 23 between CNS, NNSA, and DOE’s Office of Enterprise Assessments’ Office of Enforcement.

In a July 13 letter, NNSA Administrator Lisa E. Gordon-Hagerty and Kevin L. Dressman, acting director of the Office of Enforcement, said CNS made a decision in 2016 to vacate an off-site records storage facility on Pine Ridge that had met DOE requirements.

To vacate that building, CNS sent boxes of inactive archived records, dating back to 1943, to one of three U.S. National Archives and Records Administration facilities: unclassified records went to two different federal records centers based on whether the records were textual or non-textual (e.g., films), and classified records, regardless of the medium, were transferred to a federal records center that is authorized to store classified information.

The National Nuclear Security Administration and the Tennessee Valley Authority announced last week that they intend to enter into an agreement to “down-blend” highly enriched uranium to low-enriched uranium in order to help produce tritium, a key “boosting” component in nuclear weapons.

The highly enriched uranium used for the “down-blending” is processed, packaged, and shipped from the Y-12 National Security Complex in Oak Ridge, according to the NNSA. Y-12 is the main storage facility for certain categories of highly enriched uranium, which can be used in nuclear weapons and in naval reactors.

Low-enriched uranium, or LEU fuel, is used in a commercial power reactor run by TVA at the Watts Bar Nuclear Plant Unit 1 near Spring City in Rhea County, southwest of Oak Ridge. Tritium is produced there by irradiating lithium-aluminate pellets with neutrons in rods known as tritium-producing burnable absorber rods, or TPBARs.

The irradiated rods are then shipped to the Savannah River Site, an NNSA production facility near Aiken, South Carolina. The Savannah River Site extracts the tritium from the irradiated rods, purifies it, and adds it to the existing inventory, according to the NNSA’s Fiscal Year 2018 Stockpile Stewardship and Management Plan.

Tritium is a radioactive isotope of hydrogen that has two neutrons and one proton. It has been described as an essential component in every nuclear weapon in the U.S. stockpile. It occurs naturally in small quantities but must be manufactured to obtain useful quantities. It enables weapons to produce a larger yield while reducing the overall size and weight of the warhead in a process known as “boosting,” the U.S. Department of Energy said in an environmental impact statement about 20 years ago.

But unlike other nuclear materials used in nuclear weapons, tritium decays at a rate of 5.5 percent per year—its half-life is about 12 years—and it must be replenished periodically.

The NNSA, a separately organized agency within DOE, said the agreement with TVA that was announced last week is for management of the down-blending campaign and the resulting material. It’s separate from an existing interagency agreement for irradiation services that started in 2000 and is in effect until November 30, 2035.

“Without this down-blending campaign, we would need to accelerate the development and execution of a strategy to provide LEU fuel for tritium production by nearly a decade,” said Phil Calbos, NNSA’s acting deputy administrator for defense programs.

The new agreement follows a determination by U.S. Energy Secretary Rick Perry on August 21 that allows the NNSA to continue transfers of enriched uranium from DOE’s inventories in support of national security, the NNSA said in a press release.

As the city celebrates its 75th anniversary, the Children’s Museum of Oak Ridge is soliciting the community’s support to ensure the legacy of a famous Oak Ridger is preserved for posterity.

Alvin Weinberg, a renowned nuclear physicist, worked on the Manhattan Project, became head of the Physics Division at Oak Ridge National Laboratory, then research director, and ultimately the director of the laboratory for 18 years. He donated his personal papers to the Children’s Museum of Oak Ridge when Selma Shapiro, the museum’s founder, was serving as its executive director. Now Shapiro’s daughter, Rhonda Bogard, is part of a core team working to permanently preserve the papers.

The goal of the project is to ensure Weinberg’s work and legacy are preserved for future generations, a press release said. Bogard thinks his work speaks for itself. “His work will be remembered for the vision and leadership it symbolizes,” she said. [Read more…]

The Spallation Neutron Source at the U.S. Department of Energy’s Oak Ridge National Laboratory has reached a new milestone by operating a complete neutron production run cycle at 1.3 megawatts, a press release said.

“Achieving the record power level with a remarkable 94 percent accelerator beam availability establishes a new baseline of operation as well as a path to operate reliably at higher powers,” the press release said. “Increased power offers researchers the ability to conduct faster scientific analyses using neutrons on more types of materials.”

SNS, a DOE Office of Science User Facility, began operations in 2006 and is currently the world’s most powerful pulsed accelerator-based neutron scattering facility, used by scientists to reveal fundamental properties and behaviors of energy and materials at the atomic scale. Neutron contributions at SNS have resulted in advances in electronic devices, improved drug delivery, and stronger building materials for transportation infrastructure, the press release said.

Citizens calling for the abolition of nuclear weapons will gather in Oak Ridge on Saturday, August 4, at 10:30 a.m. at Alvin K. Bissell Park to commemorate the atomic bombing of Hiroshima, Japan, in 1945 and to call for the United States to sign and ratify the Treaty on the Prohibition of Nuclear Weapons, which was adopted in July 2017 by 122 nations, a press release said.

The Oak Ridge events on August 4 are sponsored by the Oak Ridge Environmental Peace Alliance, and they will include music and political theater as well as a report on ongoing nuclear weapons production activities at Y-12, the press release said.

“Y-12 represents the full circle in time,” said OREPA coordinator Ralph Hutchison. “The age of nuclear weapons started here, with the enrichment of the Little Boy bomb’s uranium. And it continues today, in the face of world condemnation, with the production of thermonuclear secondaries and plans for a new bomb production plant, the Uranium Processing Facility, which will continue to make nuclear bomb cores for decades to come.” [Read more…]
