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…]

The mission need has been approved for a new lithium production facility at the Y-12 National Security Complex and various alternatives have been reviewed, but the cost and schedule have not yet been determined, a federal official said this month.

“Y-12 is working to ensure that its lithium production capability is maintained for current and future defense program missions,” said Steven Wyatt, public affairs manager for the National Nuclear Security Administration Production Office. “This is a challenge as this work is performed in 9204-2, a building that was constructed during World War II as part of the Manhattan Project. Ultimately, our goal is to replace 9204-2 with a modern facility, but until that has been achieved, we will continue to make improvements as needed.”

Building 9204-2 produces non-nuclear materials associated with stockpile stewardship missions, Wyatt said.

“We are not at liberty to provide any further details on this work,” he said. [Read more…]

DOE: Pavement collapse at ORNL a significant distance from U-233 storage area

A pavement collapse at Oak Ridge National Laboratory in early June was a significant distance from an area where uranium-233 is stored at Building 3019, the U.S. Department of Energy said Monday.

The collapse of about 36 square feet of pavement was near Building 3019B, which is an inactive facility, the DOE Oak Ridge Office of Environmental Management said.

The hot cells in the facility were not affected, and they do not contain radioactive material, DOE said.

“There were no immediate safety hazards to personnel, but as a precaution, the area was barricaded until crews made repairs,” DOE said.

Uranium-233, or U-233, is a fissionable material, and Building 3019 area is a secure and controlled area. The pavement collapse was reported by the Defense Nuclear Facilities Safety Board on June 19. [Read more…]

No one was injured when chunks of concrete weighing up to 20 pounds fell from the ceiling in a roped-off area in a building at the Y-12 National Security Complex in March.

No one was injured when chunks of concrete weighing up to 20 pounds fell from the ceiling in a roped-off area in a building at the Y-12 National Security Complex in March.

That area of Building 9204-2 in Y-12‘s production area had been roped off to restrict worker access. The controlled area has been in place since 2009, said B&W Y-12, the plant’s managing and operating contractor. Access to the area was controlled with marker tape and boundary markers.

When the ceiling fell in that part of the building, large chunks of concrete rebounded into a frequently used walkway and an adjacent welding station, the Defense Nuclear Facilities Safety Board reported in the week ending March 21. Workers had used the welding station earlier in the day, the DNFSB said.

B&W Y-12 said chunks of the concrete fell to the floor and struck a portable welding exhaust unit located inside the controlled area. Some small pieces of the concrete also scattered outside of the area. Personnel in a nearby area heard the noise, discovered the problem, and immediately notified the shift manager, per procedures, the contractor said. [Read more…]

House-passed budget could avoid second shutdown; Senate may vote this week

A bipartisan budget bill being considered in Congress could avoid a second government shutdown and provide relief to federal employees and government contractors in Oak Ridge, including at the Y-12 National Security Complex, which was prepared to furlough up to 3,600 workers during the first shutdown in October.

The U.S. House of Representatives has passed a budget bill that could avoid a second government shutdown in mid-January, a development that will likely offer some relief to federal employees and government contractors in Oak Ridge—and to the businesses that support them.

U.S. Rep. Chuck Fleischmann, a Tennessee Republican, said he supported the Bipartisan Budget Act of 2013 in the House on Thursday.

“Tonight, the House took a modest step toward reforming spending and setting our government on a more stable path,” said Fleischmann, a second-term congressman whose district includes Oak Ridge.

But the bill still has to pass the deeply divided Senate, which is preparing to take up the budget bill this week. The Washington Post reported that Democrats are still trying to come up with the 60 votes necessary to break a GOP-led filibuster in the Senate. [Read more…]

The proposed multi-billion-dollar building that would process uranium at the Y-12 National Security Complex should be buried below ground, an Oak Ridge nonprofit organization and a Washington, D.C.-based group told federal safety officials in a Monday letter.

The groups planned to make their request during an all-day meeting and public hearing of the Defense Nuclear Facilities Safety Board in Knoxville on Tuesday. The board is meeting in two sessions from 8 a.m. to noon and 2 to 6 p.m. today (Tuesday) at the Knoxville Convention Center.

The Monday letter was from the Alliance for Nuclear Accountability in Washington, D.C. Among the dozen signatories is Ralph Hutchison, coordinator of the Oak Ridge Environmental Peace Alliance, a group that has long been critical of the nuclear weapons work at Y-12. OREPA said the letter’s signatories represent thousands of members at sites across the country. [Read more…]

Workers have repaired a roll-up door that failed to close when a fire alarm system was activated at a high-security uranium storage building at the Y-12 National Security Complex in May.

“The fire alarms were activated due to smoke from a belt of a fan with a failed bearing, but there was no fire,” the Defense Nuclear Facilities Safety Board said in a May 24 report. “The signal to the door closure device should cause a cable to release, allowing the door to close, but this did not occur because permanent deformation (kinks) in the cable caused it to knot when tension was released.” [Read more…]

KNOXVILLE—President Barack Obama recently nominated University of Tennessee alumnus Kenneth L. Mossman to the Defense Nuclear Facilities Safety Board.

Now a professor of health physics at Arizona State University, Mossman is an expert in radiation health and safety. He received his master’s degree in 1970 and doctorate in 1973, both in radiation biology, from UT and is a member of the Dean’s Advisory Board for the College of Arts and Sciences. He established the Ken and Blair Mossman Professorship in Biomedicine, currently held by Associate Dean and Professor Cynthia Peterson.

The Defense Nuclear Facilities Safety Board is a five-member executive branch agency with safety oversight of all U.S. nuclear weapons facilities. Its mission is to identify potential threats to public health and safety at the U.S. Department of Energy’s defense nuclear facilities and to make safety recommendations to the secretary of energy and to the president. Among other things, the DNFSB issues weekly reports on Oak Ridge National Laboratory and Y-12 National Security Complex.

East Fork Poplar Creek

East Fork Poplar Creek starts at a spring at the Y-12 National Security Complex and flows through Oak Ridge. About six million gallons of water spilled into it in early June, killing several thousand small fish, after a 10-inch water line ruptured at Y-12.

The break in a 10-inch water pipe at the Y-12 National Security Complex on a Friday night in June—it spilled about six million gallons of water and killed several thousand small fish—was discovered by a diligent engineer who had returned to the plant to check on an abnormal water tower report, officials said.

The Defense Nuclear Facilities Safety Board reported that the plant contractor’s utilities and environmental compliance organizations both had had indications of an abnormal condition, but B&W Y-12 had not established a procedure to respond to the signals.

“The break was discovered because a diligent system engineer decided to come back in to the site and check on an anomalous report of a low level in a water tower that had cleared as the pumps refilled the tank,” the DNFSB report said. “B&W management is evaluating ways to improve recognition of a problem from the available indications during off hours.” [Read more…]
