Teachers in more than a dozen East Tennessee schools have won 25 “mini-grants” in an education program meant to recognize and support teaching excellence, and help teachers with specific projects or curricula.

The grants focus primarily on projects meant to help students learn about science, technology, engineering, and math, a press release said. UCOR, a federal cleanup contractor in Oak Ridge, announced the grant winners Wednesday.

The winners and their proposed projects and schools are: [Read more…]

Microwaves could melt uranium at UPF, help remove carbon impurities

New microwaves that can melt metal and help remove carbon impurities from uranium could be used in the proposed Uranium Processing Facility at the Y-12 National Security Complex.

Y-12 doesn’t plan to use any of its traditional ovens, known as vacuum induction melters, or VIMs, in the UPF, officials said. Those ovens use electric currents and a magnetic field to melt metal.

But it’s easier to “float out” carbon impurities in microwaves because they don’t stir molten metals the way the traditional ovens do, Y-12 officials said. Carbon contaminants in uranium castings could be reduced by 30 percent.

Y-12 melts and casts uranium to combine it into hollow cylinders for storage, make parts for the nation’s nuclear weapons stockpile, and supply nuclear fuel for the U.S. Navy. Microwaves could eventually be used for all three tasks. [Read more…]

B&W team says it’s the best choice for Y-12, Pantex contract

One of the two teams that did not win the $23 billion contract to manage and operate two nuclear weapons plants in Tennessee and Texas said newly released federal documents show it had the best bid.

The contract to manage the Y-12 National Security Complex in Oak Ridge and Pantex Plant in Amarillo, Texas, was awarded to Consolidated Nuclear Security LLC, of Reston, Va., on Jan. 8. The consolidated contract, the first ever for the National Nuclear Security Administration, is expected to save money.

But the two losing teams—Nuclear Production Partners LLC of Lynchburg, Va., and Integrated Nuclear Production Solutions LLC of Oak Ridge—filed bid protests. On April 29, the U.S. Government Accountability Office upheld those protests in part. The GAO questioned whether the NNSA had properly evaluated the expected savings, and the agency recommended that the contract procurement be re-opened and more information requested from the bidders.

The three protesters who broke into the Y-12 National Security Complex in July and vandalized a uranium storage building must stay in jail until they are sentenced Sept. 23, a federal judge said Friday.

The three protesters—Greg Boertje-Obed, 57; Megan Rice, 83; and Michael Walli, 64—had sought to be released until their sentencing hearings this fall. They each face up to 30 years in prison.

But U.S. District Judge Amul R. Thapar denied that request in a four-page order filed late Friday afternoon. [Read more…]

KNOXVILLE—The Catholic nun, house painter, and laborer who broke into the Y-12 National Security Complex in July and splashed human blood and spray-painted slogans on a uranium storage building were found guilty on two federal counts Wednesday, one charging them with property depredation of more than $1,000 and the other alleging they willfully injured national defense premises.

The three protesters—Megan Rice, 83; Michael R. Walli, 64; and Greg Boertje-Obed, 57—were taken to the Blount County jail after the verdict was read at the end of a two-day trial in U.S. District Court in Knoxville. Dozens of courtroom supporters sang softly as the three anti-nuclear weapons activists were taken into custody after about 2.5 hours of deliberations by the nine men and three women on the jury panel.

Boertje-Obed, Rice, and Walli have a detention hearing on Thursday morning. Each faces up to 30 years in prison. [Read more…]

After one federal agency upheld parts of two bid protests, a second one on Wednesday announced it will request more information from the three teams that submitted bids on a contract to manage and operate two nuclear weapons plants in Tennessee and Texas.

In January, the National Nuclear Security Administration announced it had awarded a contract valued at about $23 billion to Consolidated Nuclear Security LLC, or CNS, to manage and operate the Y-12 National Security Complex in Oak Ridge and Pantex Plant near Amarillo, Texas. [Read more…]

KNOXVILLE—The case against three anti-nuclear weapons activists who broke into the Y-12 National Security Complex in July and vandalized a uranium storage building could go to a jury this afternoon.

The government rested its case yesterday, and the defense rested this morning after the three defendants—Greg Boertje-Obed, Megan Rice, and Michael Walli—testified.

The three acknowledge sneaking into Y-12 on July 28, cutting through high-security fences, and pouring blood and spray-painting biblical passages on the Highly Enriched Uranium Materials Facility, where most of the nation’s bomb-grade uranium is stored. But they say they were religiously motivated and peacefully protesting the plant’s nuclear weapons work, symbolically disarming the 811-acre plant. [Read more…]

The government rested on Tuesday in the federal trial against three protesters accused of vandalizing a uranium storage building at the Y-12 National Security Complex in July.

The three anti-nuclear weapons activists—Greg Boertje-Obed, Megan Rice, and Michael Walli—face charges of property depredation and willfully injuring national defense premises.

Jury selection was Monday, and the trial started Tuesday.

It resumes at 9 a.m. today in U.S. District Court in Knoxville.

Rice is expected to resume testifying this morning.

Quigley of New Orleans, left, an attorney for one of the three anti-nuclear weapons activists who spray-painted biblical passages and poured blood on a uranium storage building at the Y-12 National Security Complex in July, greets supporters outside U.S. District Court in Knoxville on Tuesday.

Attorneys for the three protesters on trial this week for vandalizing a uranium storage building at a nuclear weapons plant said the government doesn’t have enough evidence to convict the defendants on a national defense charge, the most serious of the two remaining charges.

The national defense charge alleges Greg Boertje-Obed, Megan Rice, and Michael Walli willfully injured national defense premises when they cut through three fences in a high-security Protected Area at Y-12 on July 28 and spray-painted biblical passages and poured blood on the Highly Enriched Uranium Materials Facility, where most of the nation’s bomb-grade uranium is stored. The charge carries a potential prison sentence of up to 20 years. [Read more…]
