The City of Oak Ridge has been designated a World War II Heritage City, the only city in Tennessee to receive that designation.

The National Park Service has notified the city of the designation, Oak Ridge said in a press release Tuesday.

“The American World War II Heritage Cities Program honors the contributions of local towns, cities, (and) counties, and commemorates the stories of the men, women, and children whose bravery and sacrifices shaped the U.S. home front during World War II, and still impact our nation today,” the press release said. “Only one American World War II Heritage City can be designated in each state or territory. Oak Ridge played a critical role in history and has been designated Tennessee’s American World War II Heritage City through the program. ”

Oak Ridge was a key production site during World War II as part of the top-secret Manhattan Project, a federal program to build the world’s first atomic weapons, before Germany could. Among other work, Oak Ridge enriched uranium for the first atomic bomb used in wartime and had the first reactor to make plutonium-239. A plutonium sample was sent to scientific facilities at Los Alamos, New Mexico, and more of that isotope, the fuel used in the second bomb, was produced at Hanford, Washington.

A new lithium processing facility that could be built in Oak Ridge is a priority for the National Nuclear Security Administration, which has cited worker safety and materials that have fallen from the ceiling at the old building now used at the Y-12 National Security Complex.

As a priority, the new lithium processing facility is right behind the number one priorities: the production of plutonium pits at the Savannah River Site in South Carolina and Los Alamos National Laboratory in New Mexico and uranium processing at the Uranium Processing Facility, which is now under construction at Y-12, said Charles Verdon, NNSA deputy administrator for defense programs.

NNSA Administrator Lisa Gordon-Hagerty cited the materials that have fallen from the ceiling at the old Y-12 building used for lithium processing, 9204-2, or Beta 2, in her response to questions during a budget hearing with the U.S. House Energy and Water Development Subcommittee on Tuesday.

Former director Alvin Weinberg once called it the greatest technical achievement at Oak Ridge National Laboratory. It was inspired by the campaign to build a nuclear-powered aircraft in the 1950s, and it was the first reactor to ever operate using uranium-233.

Now parts of the Molten Salt Reactor Experiment that are too radioactively “hot” for humans could be entombed in concrete.

For now, the idea is only under study, and there is no guarantee that any part of the Molten Salt Reactor Experiment, a nuclear historic landmark that has been dormant for decades, will be entombed.

But it’s one of the proposals being evaluated by the U.S. Department of Energy’s Oak Ridge Office of Environmental Management. The goal is to finish the evaluation by the end of the year.

Jay Mullis, manager of the Oak Ridge Office of Environmental Management, presented the proposal to the Oak Ridge City Council and Site Specific Advisory Board in two separate meetings earlier this month. The entombment proposal is one of five items being evaluated as part of a 45-day review started by DOE’s Environmental Management, or EM, program in June. [Read more…]

​NASA’s New Horizons spacecraft just accomplished one of the most exciting feats in the history of space exploration. After a 9.5-year, 3-billion-mile journey, the mission’s historic flyby of Pluto has provided us with our first-ever closeup views of the frozen world at the edge of the solar system. It’s a remarkable achievement, one that wouldn’t have been possible without careful planning, ingenuity—and a little help from the U.S. Department of Energy.

In 2006, when NASA engineers were designing New Horizons, they knew that it would need a long-lasting, compact and incredibly reliable power source to survive the cold, dark reaches of outer space.

Solar power was out of the question. The spacecraft’s itinerary would take it billions of miles from the center of the solar system into the realm of Pluto and the Kuiper Belt. That far out, the Sun shines with just a tiny fraction of the intensity we see here on Earth—scarcely brighter than the stars in the night sky. Other options like batteries or fuel cells wouldn’t last long enough. [Read more…]

ORNL: Neutrons find ‘missing’ magnetism of plutonium

Groundbreaking work at two U.S. Department of Energy national laboratories has confirmed plutonium’s magnetism, which scientists have long theorized but have never been able to experimentally observe. The advances that enabled the discovery hold great promise for materials, energy, and computing applications.

Plutonium was first produced in 1940, and its unstable nucleus allows it to undergo fission, making it useful for nuclear fuels as well as for nuclear weapons. Much less known, however, is that the electronic cloud surrounding the plutonium nucleus is equally unstable and makes plutonium the most electronically complex element in the periodic table, with intriguingly intricate properties for a simple elemental metal.

While conventional theories have successfully explained plutonium’s complex structural properties, they also predict that plutonium should order magnetically. This is in stark contrast with experiments, which had found no evidence for magnetic order in plutonium. [Read more…]

The High Flux Isotope Reactor, or HFIR, now in its 48th year of providing neutrons for research and isotope production at Oak Ridge National Laboratory, has been designated a Nuclear Historic Landmark by the American Nuclear Society.

“This designation from the ANS recognizes HFIR’s role in the history of the nuclear age, but it also speaks to the excellence of its design and operation,” ORNL Director Thom Mason said. “HFIR remains one of the world’s most capable reactor-based neutron science, radioisotope production, and materials irradiation facilities, and we expect that to continue for many years.”

The designation was proposed by the ANS honors and awards committee and approved on initial ballot by the board of directors.

“The ANS Nuclear Historic Landmark signifies that a nuclear facility has played an important role in nuclear science and engineering,” ANS President Michaele C. Brady Raap said. “HFIR, with its preeminent role in isotope production and neutron science, certainly meets that criteria.”

The reactor was conceived in the late 1950s as a production reactor to meet anticipated demand for transuranic isotopes (“heavy” elements such as plutonium and curium). HFIR today is a U.S. Department of Energy Office of Science User Facility and one of the world’s sole sources of the radioisotope californium-252, used in industry and medicine. ORNL is a DOE lab.

Guest column: Explosive interest in ‘Manhattan’

WASHINGTON, D.C.—The WGN America television show “Manhattan” has galvanized the interest of millions of viewers. Shown on Sunday nights, national audiences are riveted by the dramatic tension between rival groups of scientists and the omnipresent security police in Los Alamos in 1943. “Manhattan” follows the scientists as they confront the challenges of making a workable atomic bomb while dealing with an intrusive military force, intense rivalries, and strained marital relations where couples can no longer confide in each other.

The show is a blend of fact and fiction. The primary characters are entirely fictional including the main scientist, Frank Winter; Chinese-American physicist, Sidney Liao; and wunderkind Charlie Isaacs and his most attractive wife, Abby. But “Manhattan” has preserved at least two real persona, J. Robert Oppenheimer as the director of Los Alamos, and Nobel Prize-winning physicist Niels Bohr who visits the laboratory to offer his advice.

The central tension is the race to develop two different approaches to a plutonium-based bomb. Winter believes an implosion bomb offers the best option but most of the scientists—including Oppenheimer—are more confident in a gun-type plutonium bomb similar to the design used for the uranium-based bomb. While the enmity between the two groups is exaggerated for television, “Manhattan” does a good job showing the challenges the scientists and engineers faced knowing little about the newly discovered and quite bizarre element plutonium.

In a 1965 interview with journalist Stephane Groueff, J. Robert Oppenheimer recalled: “I think the set of problems connected with implosion was the most difficult, and it required very new experimental techniques. It was not a branch of physics anyone was very familiar with. It was, from a theoretical, an observational, and a practical point of view, quite an adventure. Plutonium was a terrible test from beginning to end and never stayed quiet: it gets hot, it is radioactive, you cannot touch it, you have to coat it, and the coating always peels. It is just a terrible substance.” [Read more…]

NNSA marks 10th anniversary of Global Threat Reduction Initiative

WASHINGTON, D.C.—The National Nuclear Security Administration on Thursday marked the 10th anniversary of the Global Threat Reduction Initiative, GTRI. Since the Sept. 11 attacks, reducing the threat of terrorist acquisition of nuclear or radiological material has been a core mission of NNSA, and it is a mission that will continue into the future.

“The Global Threat Reduction Initiative’s history demonstrates how seriously we take this mission and our commitment to fulfilling President Obama’s nuclear security agenda,” said U.S. Department of Energy Under Secretary for Nuclear Security and NNSA Administrator Frank G. Klotz. “However, the threat to national and global security from state or terrorist acquisition of nuclear and radiological materials is far from gone, and our focus now is on addressing the substantial threats that remain.”

GTRI, an NNSA nuclear nonproliferation program, works with partners around the world to reduce and consolidate global stockpiles of highly enriched uranium, or HEU, and plutonium, and to secure dangerous radiological sources both at home and abroad. GTRI and its predecessor programs have removed and secured more than enough material for 980 nuclear weapons and tens of thousands of radiological dirty bombs by converting HEU research reactors and isotope production facilities to the use of low enriched uranium, or LEU; removing or confirming disposition of HEU and plutonium; and securing nuclear and radiological sites around the world.

KNOXVILLE—Federal officials have expressed concerns about increasing cost projections and delayed construction dates for a new Uranium Processing Facility at the Y-12 National Security Complex, and a so-called Red Team has drafted an alternative approach that could keep the project at $6.5 billion or less—and help workers get out of the aging Building 9212 at Y-12 by 2025.

Thom Mason, the director of Oak Ridge National Laboratory, chaired the Red Team, and he is expected to brief federal officials in Washington, D.C., today (Monday) on the team’s report. The report will then go to Congress, Energy Secretary Ernest Moniz said in a media briefing at the Howard H. Baker Jr. Center at the University of Tennessee on Friday.

Among the questions that could be answered are which old production buildings at Y-12 should be replaced and which can be refurbished. Y-12 was built to enrich uranium as part of the top-secret Manhattan Project during World War II as the United States raced to beat Germany to build the world’s first atomic weapons. [Read more…]
