A company that has a trial fuel fabrication facility at Oak Ridge National Laboratory is collaborating with a joint venture led by GE with Hitachi to produce nuclear fuel for the U.S. Department of Defense and NASA.

The company, X-energy of Rockville, Maryland, announced the collaboration with Global Nuclear Fuel on November 6.

The two companies have an agreement to develop high-assay, low-enriched uranium TRISO fuel. The fuel could be used in defense micro-reactors and by NASA for nuclear thermal propulsion, a press release said.

Centrus Energy Corporation has a $15 million project to prepare K-1600, a building in the middle of the historic K-25 “footprint,” for demolition.

On Tuesday, Centrus announced that it had received a work authorization from the U.S. Department of Energy for decontamination and decommissioning (D&D) work at the building. The work will include removing and disposing of equipment and materials to make K-1600 non-radiologically contaminated and non-possessing (i.e. unclassified), a press release said. The work will occur between October 1, 2018, and September 30, 2019.

After the work is completed, DOE will be able to turn over K-1600 to a contractor to demolish it, the press release said. It’s one of the last remaining “legacy structures” on the 2,200-acre site of the World War II-era K-25 uranium enrichment plant, now known as the East Tennessee Technology Park, the press release said.

Many other buildings have been demolished there, including the five large gaseous diffusion buildings once used to enrich uranium for atomic weapons and commercial nuclear power plants. ETTP is now being converted into a large industrial park in west Oak Ridge. [Read more…]

NNSA, TVA agree to ‘down-blend’ uranium to produce tritium for weapons

The National Nuclear Security Administration and the Tennessee Valley Authority announced Wednesday, Aug. 22, 2018, 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. (File photo by John Huotari/Oak Ridge Today)

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.

Six months after signing one contract, Centrus Energy Corporation and UT-Battelle LLC have agreed on a new contract for engineering and testing work on technology that uses gas centrifuges to enrich uranium.

Enriched uranium can be used in nuclear power plants and in nuclear weapons, as fuel for nuclear naval vessels, and to ensure a tritium supply, which is needed to maintain the effectiveness of America’s nuclear deterrent, a press release said.

The new Centrus Energy-UT-Battelle contract is valued at about $25 million, and it runs through September 30, 2017. Under this new contract, Centrus scientists, engineers, and operators will “use the company’s unique facilities in Oak Ridge to develop and test technology improvements to reduce costs, improve manufacturability, and enhance the long-term reliability of U.S. uranium enrichment technology,” the press release said.

UT-Battelle operates Oak Ridge National Laboratory for the U.S. Department of Energy.

The uranium enrichment technology is known as the American Centrifuge technology. It’s expected to support future national security and energy security needs, the press release said. [Read more…]

Leadership Oak Ridge Class of 2016 (Submitted photo)

 

For 30 years, Leadership Oak Ridge has been informing, training, and empowering leaders in Oak Ridge and the region. With more than 1,000 graduates, Leadership Oak Ridge is one of the longest continuously running leadership programs in the United States.

Each year, a Leadership Oak Ridge class takes on a project aimed at benefiting the Oak Ridge community. This year’s class will lead and implement a plan to renovate a vital part of the Boys & Girls Club in Oak Ridge.

The Boys & Girls Club provides an opportunity for youth to engage in programs and activities to promote physical, mental, and emotional well-being.

“The Boys & Girls Club is a well-known and vital part of the Oak Ridge community, and like all programs of this type, it relies heavily on volunteer support and donations to maintain the quality and relevance of the services it delivers,” said Dennis Yates, of Centrus Energy and Leadership Oak Ridge Class of 2016.

Letter: Proud of Progress PAC endorsement, positive campaign

To the Editor:

I read the article in Wednesday’s The Oak Ridger where the reporter contacted the five candidates who were not endorsed by the Progress PAC for comments. I wonder why The Oak Ridger did not contact all the candidates.

Either way, I found most comments professional, and in particular Mike Mahathy’s and Jean Hiser’s and in general Andrew Howe’s. Both Andrew Howe’s and Laurie Paine’s, however, referenced me so I feel necessary to respond. [Read more…]

Centrus Energy Corporation announced this week that it has satisfied all the conditions to emerge from a Chapter 11 bankruptcy. The conditions were outlined in a reorganization plan approved by the U.S. Bankruptcy Court for the District of Delaware on September 5.

The plan became effective Tuesday, and Centrus, formerly known as USEC Incorporated, emerged from the restructuring in a “stronger position to supply customers with nuclear fuel and support the energy and national security needs of the United States,” a press release said.

Centrus stock was expected to begin trading on the New York Stock Exchange on Tuesday under the ticker symbol LEU.

“Throughout the restructuring process that began March 5, 2014, the company has continued to meet all of its obligations to customers and vendors and will not require external exit financing upon emergence,” the release said. The company had maintained its NYSE listing throughout the Chapter 11 process. [Read more…]
