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…]

A federal nuclear safety board has not yet rescheduled a meeting in Knoxville that had been expected to discuss this week, among other things, the risks associated with continuing to operate old buildings involved in weapons work at the Y-12 National Security Complex—and the progress made in the past year to incorporate safety into the design of the multi-billion dollar Uranium Processing Facility.

The federal Defense Nuclear Facilities Safety Board had been scheduled to have the day-long meeting and public hearing on Tuesday, Oct. 22, at the Knoxville Convention Center. But it was delayed due to the partial shutdown of the federal government, which started Oct. 1 and ended Oct. 17.

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…]

President Obama nominates UT alumnus to key nuclear post on DNFSB

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.

Y-12 operator exposed to lithium hydride received second-degree burns, returned to work

An operator injured after being exposed to lithium hydride powder at the Y-12 National Security Complex in early April sustained second-degree burns, primarily on the face and scalp, but has returned to work, federal officials said.

The operator, who is not identified in federal reports, also received some first-degree burns. But in two separate reports, officials said the employee’s injuries were healing as expected without complications, and the worker was expected to make a full recovery. [Read more…]

‘Diligent’ engineer discovers Y-12 water line break that spilled six million gallons

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…]

Equipment used in uranium casting falls from Y-12 furnace

Equipment and materials used in uranium casting operations at the Y-12 National Security Complex fell several feet from a furnace in Building 9212 last month after someone accidentally bumped a control lever, a federal safety board said in a recently released report.

The lever controls the movement of what is known as the stack assembly, which includes a crucible, mold, and uranium “charge.”

The loaded stack assembly had recently been cast, and it fell several feet from the body of an induction furnace to the base of the furnace, where loading and unloading occur, the Defense Nuclear Facilities Safety Board said in a report for the week ending April 19. [Read more…]

John Eschenberg on UPF at Rotary Club

At right, John Eschenberg, federal project director for the Uranium Processing Facility at the Y-12 National Security Complex, discusses the proposed $6.5 billion building with Leslie England and John Iacovino after a Wednesday morning Rotary Club meeting.

Note: This story was last updated at 9:53 a.m. Oct. 4.

The new $6.5 billion Uranium Processing Facility at the Y-12 National Security Complex could be larger than originally planned to make sure all the building’s equipment fits inside, a federal official said Wednesday.

The roof could be raised by 13 feet to 71 feet, said John Eschenberg, UPF federal project director at Y-12. That would give adequate room for process equipment used for machining, wet chemistry, and casting, as well as for the operators who use it.

To raise the roof, the building’s walls will be thickened from 18 inches to 30 inches, and the foundation will be thicker as well, Eschenberg said.

Some work at the site, which is located in the heart of Y-12, could begin by the end of the year, Eschenberg said. That work would include removing a parking lot and relocating a section of Bear Creek Road.
