In February 2014, two incidents at the Waste Isolation Pilot Plant, or WIPP, in New Mexico caused the shutdown of the only facility in the U.S. that permanently disposes of transuranic waste, or TRU waste. That waste is disposed in shafts, or drifts, about a half-mile below ground in an ancient salt bed. Some of that waste has come from Oak Ridge.

After months of investigations into the cause of a truck fire and a radiological release two weeks later, the U.S. Department of Energy released a recovery plan at the end of September that outlines the steps necessary to resume limited waste operations in the first quarter of 2016.

“Key elements of the recovery plan include strengthening safety programs, regulatory compliance, decontamination of the underground, increasing ventilation, mine stability and underground habitability, and additional workforce retraining,” according to a statement on WIPP’s website. [Read more…]

Fuels for the final frontier: Y-12 to help create fuel for NASA space exploration

The Y-12 National Security Complex is taking their uranium expertise to the next level—outer space.

The NNSA Production Office (NPO) at Y-12 struck an agreement earlier this year with NASA’s Glenn Research Center in Cleveland, Ohio, to support the design of a small nuclear-powered reactor with the potential to lead to small fission power reactors for future space exploration missions.

For the first phase of the project, Y-12 will research materials and manufacturing processes for a physics demonstration of a kilowatt-range nuclear reactor, known as project Kilopower, using an enriched uranium-molybdenum metallic fuel core and a lithium-hydride shield. The Kilopower concept was a 2013 R&D 100 Award winner for proof-of-principle experiments performed at the National Criticality Experiments Research Center in Nevada led by Los Alamos National Laboratory in collaboration with NASA Glenn and National Security Technologies.

“Science missions are seeking greater power and functionality,” explained Lee Mason, chief of the Thermal Energy Conversion Branch at Glenn. “We’re planning to demonstrate the technology in a ground test using a prototype U-235 reactor core.” [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.

WASHINGTON, D.C.—Secretary of Energy Ernest Moniz swore in Frank G. Klotz as the U.S. Department of Energy’s undersecretary for nuclear security and administrator of the National Nuclear Security Administration in a private ceremony on Thursday afternoon. Klotz was joined by his wife Nancy and Acting Administrator Bruce Held.

“I am very pleased that Gen. Klotz has now been sworn in as the fourth undersecretary of nuclear security and administrator for the National Nuclear Security Admiration,” Moniz said. “With his years of service to our country, his vision for NNSA’s nuclear security programs, and his dedication to supporting the men and women of the organization, I am confident Gen. Klotz will bring strong leadership and management to this critical Department of Energy mission. I look forward to working closely with Frank in support of the President’s nuclear security priorities.”

The Y-12 National Security Complex in Oak Ridge is an NNSA site. The NNSA is a separate agency within DOE.

Klotz is a retired U.S. Air Force lieutenant general. He is the former commander of Air Force Global Strike Command, a position he held from 2009 to 2011. He was confirmed by the U.S. Senate on April 8. [Read more…]

Five mercury cleanup projects wrapped up in February

Five mercury projects being performed under the American Recovery and Reinvestment Act were completed in February, with URS-CH2M Oak Ridge LLC, or UCOR, issuing the final reports.

The projects ranged from planning new facilities and planning for cost-effective disposition of mercury-contaminated media, to removing old, abandoned tanks containing mercury. All are part of getting ready for an upcoming major focus on mercury cleanup at the Y-12 National Security Complex.

In the area of Y-12 known as the West End Mercury Area, or WEMA, multiple facilities produced a lithium isotope fundamental to the development of the hydrogen weapon. Mercury was used in that process. In those facilities, various amounts of mercury are present in the process pipes and equipment, drains and sumps, soil surrounding the facilities, storm sewers, and stream sediments.

UCOR announces last shipment of unusual K-25 wastes

Workers have finished shipping a stockpile of unusual classified, radioactive wastes from the East Tennessee Technology Park, the former K-25 site, federal cleanup contractor UCOR announced last week.

The waste was generated at the K-25 site more than a decade ago, and it was stored in Vault 1X at the K-25 Building, UCOR said. It required off-site disposal.
