WASHINGTON, D.C.—Russia has converted 500 metric tons of highly enriched uranium—the equivalent of 20,000 nuclear warheads—and the resulting low enriched uranium, or LEU, has been delivered to the United States, fabricated into nuclear fuel, and used in nuclear power plants to generate nearly 10 percent of all U.S. electricity for the past 15 years, federal officials said.

That’s roughly half of all commercial nuclear energy produced domestically during that period, a U.S. Department of Energy press release said.

Energy Secretary Ernest Moniz announced the final LEU shipment on Thursday.

The LEU was derived from Russian weapons-origin highly enriched uranium, or HEU, under the 1993 U.S.-Russia HEU Purchase Agreement, commonly known as the Megatons to Megawatts Program, the press release said. [Read more…]

Danny McKnight’s U.S Army Rangers’ unit was the focus of the movie “Black Hawk Down”—the story of a battle that occurred in Somalia 20 years ago.

McKnight told an audience at Oak Ridge National Laboratory on Monday, Veterans Day, that he visits the six graves of men who lost their lives in that battle every five years as he did this past October.

“It reminds me of how special they were and still are to me,” said McKnight, a 28.5-year veteran of the Rangers and author of the book “Streets of Mogidishu—Leadership at Its Best” that recounts the battle of Oct. 3-4, 1993. “I want people to know about it because I want people to understand that’s what we need to do. I never want to forget them. I don’t care if they’ve been gone 50 years. As long as I can walk, talk and breathe every five years, they’ll see me. I know they see me.”

Three hundred people recently attended the unit’s first reunion in 20 years in October when they met in Dallas. [Read more…]

High-activity radioactive materials removed from Mexico, NNSA says

WASHINGTON, D.C.—The National Nuclear Security Administration announced this week that it has recovered high-activity radioactive materials from an oncology clinic in Ciudad Juarez, Mexico.

NNSA’s Global Threat Reduction Initiative, or GTRI, and the Mexican National Commission for Nuclear Security and Safeguards, or CNSNS, jointly supported the removal, a press release said. The device containing the source was packaged and securely transported to the U.S. for final disposition.

“This operation is part of NNSA’s broad strategy to strengthen both U.S. and global security by keeping dangerous nuclear and radiological material safe and secure,” said NNSA Deputy Administrator for Defense Nuclear Nonproliferation Anne Harrington. “This mission is a good example of our long-standing partnership with Mexico to prevent proliferation and secure the materials that can be used by terrorists in an improvised nuclear device or dirty bomb.” [Read more…]

Officials celebrate conversion of historic hotel to assisted living center

Alexander Inn Groundbreaking

Local, state, and federal officials join volunteers and nonprofit and business executives for a groundbreaking ceremony at the historic Alexander Inn on Thursday.

Top military leaders and scientists once stayed at this historic two-story hotel in the heart of Oak Ridge, and now it’s being converted into an assisted living center.

The $5.5 million renovation of the Alexander Inn at Jackson Square started in July, the culmination of a years-long preservation effort. It could be complete by mid-2014, said Rick Dover, manager of Family Pride Corp., the company converting the hotel.

The Guest House Senior Living at the Alexander Inn will have 62 rooms, including a 17-room memory care wing.

The hotel was built during the Manhattan Project, a top-secret federal program to build the world’s first atomic bombs during World War II. Guests who once stayed there included Gen. Leslie Groves, Secretary of War Henry Stimson, and physicists J. Robert Oppenheimer and Enrico Fermi. [Read more…]

ORNL uses neutron scattering, supercomputing to study biofuel production

Researchers studying more effective ways to convert woody plant matter into biofuels at Oak Ridge National Laboratory have identified fundamental forces that change plant structures during pretreatment processes used in the production of bioenergy.

The research team, which published its results in Green Chemistry, set out to decipher the inner workings of plant cell walls during pretreatment, the most expensive stage of biofuel production. Pretreatment subjects plant material to extremely high temperature and pressure to break apart the protective gel of lignin and hemicellulose that surrounds sugary cellulose fibers. [Read more…]

Knoxville Regional LEGO tournament Saturday at Hardin Valley

Knoxville Regional LEGO Tournament

About 100 students representing 18 Knoxville area teams will compete in a regional LEGO tournament Saturday at Hardin Valley Academy, working with miniature robots that perform required tasks on a table.

Robertsville Middle School is the defending state champion. Under the new format this year, the team needs to qualify in this regional tournament before advancing to the state tournament.

“This year’s theme in ‘Nature’s Fury,’” said John Tilson, a Hardin Valley science teacher and Saturday’s tournament director. “The students have a lot of problems they need to solve. They design and build a predominantly LEGO robot. They perform a certain number of challenges and they get points for each challenge. They have to do certain rescues, and they have to move certain items from place to place.” [Read more…]

B&W seeks investors on program to build small nuclear reactors in Oak Ridge

The Babcock and Wilcox Co. has already invested more than $360 million in a project that could result in a small nuclear reactor in west Oak Ridge, and now the North Carolina company is looking for investors and possibly majority owners.

The mPower small modular reactor, or SMR, program is expected to have a nuclear power plant operating at the former Clinch River Breeder Reactor Site by 2022. Initially, it could have two small reactors, a “twin pack,” and produce 360 megawatts.

On Wednesday, Marshall Cohen, B&W vice president for government affairs and communications, said the company is seeking major corporations who are interested in taking a “strong position,” up to and including ownership, including majority ownership.

“We would reduce our ownership to one that really matches the scope of work going forward,” Cohen said. [Read more…]

NNSA partners with Russia to recover ‘dirty bomb’ material

WASHINGTON, D.C.— The National Nuclear Security Administration, in partnership with the Russian Federation, has successfully completed the removal of 14 Russian radioisotope thermoelectric generators, or RTGs, from the Northern Sea Route. These devices, which contain high-activity radioactive sources, powered navigational beacons along Russia’s northern coastline. With this removal, the U.S. Department of Energy has completed its efforts to recover RTGs along the Northern Sea Route, a press release said.

RTGs were used for many years in Russia to generate electrical power at remote locations, including lighthouses and navigational beacons. The 14 RTGs recently recovered by DOE contain more than one million curies of strontium-90, a high-activity radioisotope that could be used in a dirty bomb. [Read more…]
