A reactor core that includes highly enriched uranium alloy components produced at the Y-12 National Security Complex in Oak Ridge could power future space exploration, including on the Moon and Mars, federal officials said.

The reactor core fabricated at Y-12 has been delivered to the Nevada National Security Site, where it is being used in a experiment called Kilopower. That’s a new power source that could provide safe, efficient energy for future robotic and human space exploration missions, according to the National Aeronautics and Space Administration, or NASA. The power source could help provide lighting, water, and oxygen on those missions.

NASA said the pioneering space power system, which would use nuclear fission, could provide up to 10 kilowatts of continuous electrical power for at least 10 years. That’s enough power to run two average households.

Four Kilopower units would provide enough power to establish an outpost, NASA said. The system could enable long-term stays on planetary surfaces.

Testing, which started in November, is being performed through this spring at the National Critical Experiments Research Center in the Device Assembly Facility at the Nevada National Security Site. [Read more…]

About half of the uranium-233 waste stored in Building 3019 at Oak Ridge National Laboratory has been shipped to a disposal facility in Nevada.

The shipments were completed in August, said Jay Mullis, manager of the U.S. Department of Energy’s Oak Ridge Office of Environmental Management.

But federal officials were only recently able to announce the end of the shipments of the waste from the Consolidated Edison Uranium Solidification Program, or CEUSP. The waste contained radioisotopes of uranium from a 1960s research and development test of thorium and uranium reactor fuel at the Consolidated Edison Indian Point-1 reactor in New York. The test was sponsored by the Atomic Energy Commission, a predecessor to the U.S. Department of Energy.

The shipments were completed 10 months ahead of schedule, Mullis told the Oak Ridge Site Specific Advisory Board on Wednesday, November 8. The CEUSP waste had been treated and turned into a ceramic matrix. It was shipped from Building 3019 at ORNL, where it had been stored, to the Nevada National Security Site, a former nuclear weapons proving ground about 65 miles northwest of Las Vegas. DOE started shipping the waste materials to the Nevada National Security Site in May 2015. [Read more…]

The U.S. Department of Energy is responsible for more than 80 percent of the U.S. government’s estimated $450 billion in environmental liabilities, a federal agency said in a report published this year.

The agency, the U.S. Government Accountability Office, added the government’s environmental liabilities to a high-risk list of federal programs and operations in a report published in February.

Total environmental liabilities for the federal government are estimated at $447 billion. DOE is responsible for about $372 billion of them, or 83 percent, according to a fiscal year 2016 estimate, the GAO said.

Most of DOE’s environmental liability is related to nuclear waste cleanup, the GAO said. Fifty percent of it is at two cleanup sites: the Hanford Site in Washington state and the Savannah River Site in South Carolina.

The GAO—an independent, nonpartisan agency that works for Congress—said DOE’s total reported environmental liability has generally increased since 2000. It’s roughly doubled from a low of $176 billion in fiscal year 1997 to the higher estimate of $372 billion in fiscal year 2016.

“In the last six years alone, EM (environmental management) has spent $35 billion, primarily to treat and dispose of nuclear and hazardous waste and construct capital projects to treat the waste, while EM’s portion of the environmental liability has grown over this same time period by over $90 billion, from $163 billion to $257 billion,” the GAO said.

In the past few fiscal years, DOE environmental management has spent about $6 billion per year. The budget request submitted to Congress by President Donald Trump in May asked for $6.5 billion for the DOE Office of Environmental Management, the largest request in a decade.

Oak Ridge has a DOE environmental management program. It received more than $400 million in funding per fiscal year between 2013 and 2016. The Oak Ridge Office of Environmental Management has major cleanup projects at the East Tennessee Technology Park (the former K-25 site), Oak Ridge National Laboratory, and Y-12 National Security Complex. Cleanup work depends upon funding, but it could continue into the mid-2040s. Although they might be in various stages, projects that are under way now include finishing demolition work at ETTP by 2020, disposing of uranium-233 at ORNL, addressing high-risk excess facilities at ORNL and Y-12, building a Mercury Treatment Facility at Y-12, and shipping transuranic waste to the Waste Isolation Pilot Plant in New Mexico.

This story was updated at 5 p.m. Aug. 30.

They haven’t agreed on a final budget number, but the Trump administration and the U.S. House and Senate have proposed spending between about $33 million and $52 million in the next fiscal year to continue disposing of uranium-233 waste materials that are stored at Oak Ridge National Laboratory in a building that is the oldest continuously operating nuclear facility in the U.S. Department of Energy complex.

The uranium-233, or U-233, waste is now stored in secure vaults in Building 3019, which was built in the 1940s at ORNL. Removing the waste could allow ORNL to relax its overall security posture, which will reduce costs, eliminate nuclear safety issues, and make the campus more conducive to collaborative science, according to a U.S. Senate Appropriations Committee report published in July.

Some of the waste is from a 1960s research and development test in New York, and it is being shipped to the Nevada National Security Site, a former nuclear weapons proving ground about 65 miles northwest of Las Vegas. In interviews this summer, DOE officials in Oak Ridge declined to discuss the amount of that waste that has been shipped to Nevada or to say how long the shipments might continue. But they are making progress, said Jay Mullis, acting manager of DOE’s Oak Ridge Office of Environmental Management.

Once all of those materials are shipped, the remaining U-233 at ORNL will be treated in “hot cell” facilities across the street from Building 3019, at Building 2026. The DOE’s Oak Ridge Office of Environmental Management owns both buildings.

Mullis said there is other U-233 waste stored in Building 3019, including from glovebox research at ORNL, from reactor plates, and from conglomerate materials. [Read more…]

NNSA awards, then rescinds contract to manage, operate Nevada National Security Site

The National Nuclear Security Administration awarded but then rescinded a contract to manage and operate the Nevada National Security Site, where some waste from Oak Ridge is shipped.

The NNSA, a semi-autonomous agency within the U.S. Department of Energy, awarded the contract to manage and operate the Nevada National Security Site, or NNSS, to Nevada Site Science Support and Technologies Corporation, or NVS3T, on August 26, a statement said. The winning proposal identified NVS3T as a wholly owned subsidiary of Lockheed Martin.

In making the award, NNSA evaluated past performance and other factors based upon the proposal as submitted, the statement said. The award was valued at $5 billion over 10 years if all options were exercised.

But after the award was made, DOE and NNSA learned that Leidos Innovations Corporation had acquired NVS3T from Lockheed Martin. [Read more…]

A new group of state and federal workers that was announced Tuesday could discuss contentious waste-related issues that include concerns over shipping low-level radioactive waste from a World War II-era building in Oak Ridge to a federal landfill in Nevada.

The new group, which will include senior-level state and federal employees, was announced in a six-page agreement, a memorandum of understanding signed last week by Energy Secretary Ernest Moniz and Nevada Governor Brian Sandoval.

The talks started more than a year ago, after Sandoval sent a letter to Moniz expressing concerns over the proposed disposal of the radioactive waste at the Nevada National Security Site, a former nuclear weapons proving ground about 65 miles northwest of Las Vegas.

The waste contains radioisotopes of uranium from the Consolidated Edison Uranium Solidification Project. It originated from a 1960s research and development test of thorium and uranium reactor fuel in New York. It is stored at Oak Ridge National Laboratory in Building 3019—the oldest continuously operating nuclear facility in the Department of Energy complex—in 403 ceramic-like uranium oxide monoliths. Each of the monoliths is bonded to the inside of a steel canister about 3.5 inches in diameter and about two feet long. [Read more…]

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…]

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.

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.

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.
