It’s Oak Ridge’s birthday today, September 19.

Oak Ridge was picked for the top-secret Manhattan Project on September 19, 1942. That was the day 72 years ago when General Leslie Groves approved the acquisition of 59,000 acres of land along the Clinch River for what soon became the Manhattan Project, a federal effort to build the world’s first atomic bombs.

By the time President Roosevelt authorized the Manhattan Project on December 28, 1942, work on the East Tennessee site where the first production facilities were to be built was already under way.

Oak Ridge became the home of two uranium enrichment plants (K-25 and Y-12), a liquid thermal diffusion plant (S-50), and a pilot plutonium production reactor (X-10 Graphite Reactor). Groves approved Oak Ridge as the site for the pilot plutonium plant and the uranium enrichment plant in 1942. Manhattan Project engineers had to quickly build a town to accommodate 30,000 workers—as well as build the enormously complex plants.

KNOXVILLE—The only “car” that most people associate with printers is a “car-tridge” of ink, but that may soon change thanks in part to several students at the University of Tennessee in Knoxville.

UT, Oak Ridge National Laboratory, Local Motors, Cincinnati Incorporated, and Oak Ridge Associated Universities teamed up to print a working, drivable car over the weekend at the International Manufacturing Technology Show in Chicago.

The Strati 3D, officially produced by Local Motors, which has an office on Market Square in Knoxville, highlighted the show and placed what sounds like a product of science fiction firmly in the realm of reality.

“This brand-new process disrupts the manufacturing status quo,” said John B. Rogers Jr., chief executive officer of Local Motors. “It changes the consumer experience and proves that a car can be born in an entirely different way.” [Read more...]

KNOXVILLE—An international research team led by an assistant professor at the University of Tennessee in Knoxville has received a grant to help with work involving a key component of nuclear reactors.

The U.S. Department of Energy grant is worth $800,000 over three years, and it has been awarded to UT Assistant Professor Haixuan Xu. It’s part of the Nuclear Energy University Programs funding and will be used to work on a pair of particular steel alloys, a press release said.

“Getting support on this will allow us to investigate and understand the defect evolution in these materials,” said Xu, of the UT Department of Materials Science and Engineering. “What we hope to gain is fundamental insight into the effects of radiation on the alloys so that we can better predict and detect how they will break down over time and adjust the materials accordingly.”

The alloys in question would be used in sodium-cooled reactors. Xu’s research is important because little is known about how the materials stand up to high levels of radiation over time. [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’

Cynthia C. Kelly

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...]
