The waste shipped from the Y-12 National Security Complex that violated a solid waste permit in Nevada included small volumes of pressurized, non-flammable gases and an energetic material, but the shipments did not pose a safety risk, the U.S. Department of Energy said Thursday.

“These items were contained within a sealed, thick steel assembly that was disposed within a large metal box,” DOE said in response to questions. “Though the presence of these internal items were not known at the time of disposal, they do not pose any safety risk because the inner assembly is capable of containing any release of the small volumes of pressurized gases and the energetic material.”

The Department of Energy and the State of Nevada resolved regulatory actions related to the unauthorized shipments of the classified low-level radioactive waste in June. Oak Ridge Today reported about the settlement agreement on Wednesday, and the Nevada Division of Environmental Protection announced the agreement on Thursday. DOE also responded to questions about the shipments on Thursday, and the responses are included here.

At issue were 33 waste packages in 10 shipments from Y-12 to the Nevada National Security Site northwest of Las Vegas between January 2013 and December 2018. The shipments, which were quickly suspended, received publicity in July 2019 after Dan Brouillette, who was then deputy energy secretary, informed Nevada Governor Steve Sisolak about them. At the time, Nevada officials were already in a dispute with DOE about a half-ton of plutonium shipped to NNSS from the Savannah River Site in South Carolina.

The U.S. Department of Energy, National Nuclear Security Administration, and Nevada environmental regulators have agreed to a settlement after classified low-level waste shipped west from the Y-12 National Security Complex allegedly violated waste acceptance criteria at the Nevada National Security Site northwest of Las Vegas, according to documents posted online. 

The waste shipments from Y-12 received significant publicity in news stories in 2019 after Nevada Governor Steve Sisolak demanded answers from the U.S. Department of Energy about what were described as unapproved waste shipments. The shipments were incorrectly labeled, according to a letter sent that summer to former Energy Secretary Rick Perry by Sisolak and U.S. senators Catherine Cortez Masto and Jacky Rosen. Sisolak said he learned about the shipments from Y-12 to Nevada from Dan Brouillette, who was then deputy energy secretary.

Waste shipments from Y-12 were suspended that July. They remained suspended for almost two years. Shipments of low-level waste resumed in May this year, according to the Defense Nuclear Facilities Safety Board. Work continues to obtain approval to dispose of weapons-related material, the DNFSB said.

The settlement agreement, which was signed in June, addresses reimbursement and factual findings, and it includes, as an attachment, information about how the shipments from Y-12 allegedly violated waste acceptance criteria at NNSS.

  Alarms designed to detect a nuclear criticality accident at the Y-12 National Security Complex have been tested, and the systems functioned appropriately and as required, the plant said in November. Y-12 has had a criticality accident alarm system since 1945. A criticality accident would occur if there were an uncontrolled nuclear chain reaction. It could result in the release of radiation and significant exposures to nearby workers if the area were not immediately evacuated. It’s something that the plant takes steps to avoid. The alarms are designed to alert workers if there is an accident. A nuclear criticality alarm at the 811-acre plant, which works on nuclear weapons components and stores highly enriched uranium, has been given credit for helping to save lives in a nuclear criticality accident in 1958. In that case, which was the first process criticality accident in the United States, Y-12 employees immediately evacuated when they heard the alarm. A report published by Consolidated Nuclear Security, a federal contractor, said the basic design and electronic configuration of the older criticality alarm system installed in Y-12’s existing facilities, with the exception of the Highly Enriched Uranium Materials Facility, date back to 1957. The legacy system has received many upgrades since installation, and detector stations have been removed and relocated as enriched uranium operations have evolved, said the report, titled “Qualification of Y-12 Legacy Criticality Accident Alarm System Detectors.” [Read more…]

The Y-12 National Security Complex in Oak Ridge manufactured the uranium reactor core for a federal experiment that tested whether a nuclear energy source could provide power for space exploration.

“The full-power run showed that it may be feasible for NASA to use small fission reactors for deep space exploration and manned missions to the moon and Mars,” the National Nuclear Security Administration said in May.

The NNSA, which is part of the U.S. Department of Energy, worked with NASA (the National Aeronautics and Space Administration) on the project. It’s nicknamed KRUSTY, an acronym for Kilowatt Reactor Using Stirling Technology.

“In a joint venture with NASA last year, NNSA completed final design, fabrication, and full-power testing of a nuclear criticality experiment that can be used for a manned lunar or Mars space mission,” NNSA Administrator Lisa Gordon-Hagerty said in a post published on Twitter on Friday.

The uranium reactor core from Y-12 was delivered to the National Criticality Experiments Research Center at the Nevada National Security Site in the fall of 2017. [Read more…]

The National Nuclear Security Administration is deploying systems that will counter drones at four sites that house special nuclear materials, including the Y-12 National Security Complex in Oak Ridge.

Deployed by the Office of Defense Nuclear Security, the systems are designed to mitigate any malicious aerial intruders at NNSA sites. They will have the capability to detect, identify, track, and intercept unsanctioned and suspicious drones, the NNSA said Monday.

One system has already been deployed at Los Alamos National Laboratory in New Mexico.

“We needed a system to counter threats ranging from on-site disruption by protestors to intelligence gathering, surveillance, and reconnaissance of NNSA sites, plants, and labs,” said Lewis Monroe III, director of security operations and programmatic planning. [Read more…]

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 uranium-233 waste shipped from Building 3019 at ORNL

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.

Note: This story was last updated at 3:20 p.m. September 4.

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…]
