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 three protesters who broke into the Y-12 National Security Complex and vandalized a uranium storage building three years ago returned to the nuclear weapons plant during a march in Oak Ridge on Saturday.

The march and rally were organized by the Oak Ridge Environmental Peace Alliance as part of a series of events that commemorate the 70th anniversary of the bombings of Hiroshima and Nagasaki, Japan, near the end of World War II. Uranium for the first bomb, the Little Boy atomic bomb that was dropped over Hiroshima on August 6, 1945, was enriched at Y-12.

The three protesters—Greg Boertje-Obed, Megan Rice, and Michael Walli—were convicted on two felony charges on May 8, 2013, in U.S. District Court in Knoxville. But their conviction on the more serious felony sabotage charge was overturned two years later, on May 8, 2015, by the U.S. Court of Appeals for the Sixth Circuit in Cincinnati. Boertje-Obed, Rice, and Walli were released on May 16 and have a re-sentencing hearing on September 15 in Knoxville. [Read more…]

The three protesters who broke into the Y-12 National Security Complex three years ago and vandalized the Highly Enriched Uranium Materials Facility will discuss their Oak Ridge action in their first public reunion since they were released from prison in May.

Greg Boertje-Obed, Megan Rice, and Michael Walli will speak at the Church of the Savior (UCC) in Knoxville at 7 p.m. today (Friday, August 7).

Their sabotage conviction from the July 28, 2012, incident was overturned earlier this year. Since their release from prison in May, the three protesters, who are described as nonviolent peace activists, have appeared on national and international news programs, organizers said. [Read more…]

Bear Creek Road Extension and Bridge

Pictured above is the new Bear Creek Road extension and bridge on the west side of the Y-12 National Security Complex.

 

They called it their first major milestone: the completion of site readiness work, delivered on time and under budget. The work included the relocation of Bear Creek Road, a new bridge, and construction of a haul road.

It’s part of the project to build a Uranium Processing Facility at the Y-12 National Security Complex. UPF could replace World War II-era buildings at Y-12. The project has been capped at $6.5 billion, and it’s expected to be completed by 2025.

Federal officials and contractors celebrated the completion of the site readiness subproject in a Friday morning ceremony at Y-12. [Read more…]

Guest column: B&W Y-12 improved Y-12, made a big difference in the community

It has been almost 14 years since B&W Y-12 LLC took over operation of the Y-12 National Security Complex in Oak Ridge.

Soon a new contractor will be in charge. Thanks to the work of the B&W Y-12 team and many others, they will inherit a very different and much improved facility.

One only needs to approach Y-12 to see the changes. The first thing you will see is the New Hope Center, built as a public-private partnership and located just outside the secure gates of Y-12 to make sure public access is easy. It has conference space, an outstanding auditorium, and a museum that highlights everything from Y-12’s critical role in the Manhattan Project, to the NASA “moon box” built by Y-12, to Y-12’s role in winning the Cold War. Y-12 had always been a secret place and this space built with the public in mind was a major change.

The modernization process is even more obvious inside the gate. Y-12 completed and opened the new Highly Enriched Uranium Materials Facility. It’s a state of the art building. The new Uranium Processing Facility will be just as impressive with design work well underway. Both facilities allow the U.S. Department of Energy to close down old buildings that date back to the Manhattan Project. With the HEUMF and UPF in place, Y-12 will be far more efficient with operations not only more secure, but centralized in one place instead of being spread out over several locations. [Read more…]

KNOXVILLE—Federal officials have expressed concerns about increasing cost projections and delayed construction dates for a new Uranium Processing Facility at the Y-12 National Security Complex, and a so-called Red Team has drafted an alternative approach that could keep the project at $6.5 billion or less—and help workers get out of the aging Building 9212 at Y-12 by 2025.

Thom Mason, the director of Oak Ridge National Laboratory, chaired the Red Team, and he is expected to brief federal officials in Washington, D.C., today (Monday) on the team’s report. The report will then go to Congress, Energy Secretary Ernest Moniz said in a media briefing at the Howard H. Baker Jr. Center at the University of Tennessee on Friday.

Among the questions that could be answered are which old production buildings at Y-12 should be replaced and which can be refurbished. Y-12 was built to enrich uranium as part of the top-secret Manhattan Project during World War II as the United States raced to beat Germany to build the world’s first atomic weapons. [Read more…]

U.S. attorney: Y-12 security compromises will be vigorously prosecuted

U.S. Attorney William C. “Bill” Killian commended the sentences given to the three Y-12 protesters on Tuesday, and he said he hoped it would send a strong message.

“The Y-12 National Security Complex plays a critical role in our country’s national defense,” Killian said in a Wednesday statement. “People cannot take the law into their own hands and unlawfully intrude upon sensitive government facilities. Those who violate the law and compromise the security of the Y-12 National Security Complex will be vigorously prosecuted.”

The three anti-nuclear weapons activists were convicted of sabotage in May 2013 for breaking into Y-12 on July 28, 2012, cutting through high-security fences, and splashing blood and spray-painting slogans on the Highly Enriched Uranium Materials Facility. The fortress-like HEUMF stores most of the nation’s bomb-grade uranium. [Read more…]

KNOXVILLE—The three protesters who broke into the Y-12 National Security Complex in July 2012 and splashed human blood and spray-painted slogans on a uranium storage building were sentenced to three to five years in prison on Tuesday.

Megan Rice, an 84-year old Catholic nun who last lived in Washington, D.C., received the shortest sentence. She was sentenced to 35 months, or just under three years. Rice is the oldest of the three anti-nuclear weapons activists. She also has the least extensive criminal history, Judge Amul R. Thapar said during a 4.5-hour sentencing hearing in U.S. District Court in Knoxville on Tuesday afternoon.

The other two protesters, Greg Boertje-Obed and Michael Walli, both were sentenced to 62 months, or a little more than five years. They have more extensive prior records. Boertje-Obed is a 58-year-old house painter from Duluth, Minn., and Walli is a 64-year-old Catholic worker and Vietnam veteran from Washington, D.C. Thapar said Boertje-Obed has 40 arrests and more than 20 convictions, and he has previously served time in prison. So has Walli. He was released on Jan. 5, 2012—about six months before the break-in—after an eight-month federal sentence for an earlier trespassing incident at Y-12.

“What do I do when eight months didn’t deter him?” Thapar asked defense attorney Chris Irwin. “It’s getting worse, not better.” [Read more…]

Judge says Y-12 protesters not contrite as snow delays sentencing

KNOXVILLE—The three protesters who cut through fences and vandalized a uranium storage building at the Y-12 National Security Complex in July 2012 have not shown contrition or accepted responsibility for what they’ve done, a federal judge said during a Tuesday sentencing hearing.

The three anti-nuclear weapons activists—Greg Boertje-Obed, Megan Rice, and Michael R. Walli—have acknowledged that they splashed human blood, hung crime scene tape, and hammered on the side of the Highly Enriched Uranium Materials Facility on July 28, 2012. They have freely given interviews to reporters and admitted that they spray-painted slogans—they called them “Biblical graffiti”—on the side of the HEUMF, which stores most of the nation’s bomb-grade uranium.

But acknowledging their actions is not the same as contrition, U.S. District Judge Amul R. Thapar suggested during a Tuesday sentencing hearing at the Howard H. Baker Jr. Courthouse in Knoxville. To accept responsibility, the trio would have to show contrition and remorse, and acknowledge that what they did was wrong, Thapar said.

However, the defendants have fought the government at every step in the 18-month-old case, the judge said. [Read more…]

Pictured above are the three anti-nuclear weapons protesters who broke into the Y-12 National Security Complex on July 28, 2012. From left, they are Michael Walli, Megan Rice, and Greg Boertje-Obed.

The three protesters convicted on federal charges after sneaking into the Y-12 National Security Complex and splashing human blood and spray-painting slogans on a uranium storage building in July 2012 will be sentenced in U.S. District Court in Knoxville on Tuesday morning.

The sentencing hearing for the three anti-nuclear weapons activists—Greg Boertje-Obed, Megan Rice, and Michael R. Walli—is scheduled to begin at 9 a.m. Tuesday. The defendants will be sentenced individually after a joint hearing to hear witness testimony and objections to a pre-sentence report.

The government plans to call retired Brig. Gen. Rodney L. Johnson as a witness. He testified at the two-day trial in May, and he is the senior vice president and deputy general manager of security operations and emergency services at Y-12.

A Catholic nun, house painter, and laborer, Boertje-Obed, Rice, and Walli were convicted in May 2013 of destroying U.S. property and attempting to injure national defense premises. They acknowledged sneaking into Y-12 before dawn on July 28, 2012, and cutting through three fences in a high-security Protected Area before vandalizing the Highly Enriched Uranium Materials Facility, where most of the nation’s bomb-grade uranium is stored. But they said their unprecedented intrusion was peaceful, religiously motivated, and nonviolent, a symbolic disarming of Y-12. [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…]
