Workers have repaired a water leak at the Oak Ridge Research Reactor at Oak Ridge National Laboratory, officials said this week.

The completion of the work was announced by UCOR, a federal cleanup contractor and partnership between URS and CH2M Oak Ridge LLC.

The seep was detected in the reactor’s pool in September 2014. While it did not pose any immediate dangers to workers or the environment, it prompted quick action by the U.S. Department of Energy, which oversees ORNL. DOE asked UCOR, its prime cleanup contractor, to develop and implement a solution to remedy the seep, a press release said. [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…]

NNSA partners with Russia to recover ‘dirty bomb’ material

WASHINGTON, D.C.— The National Nuclear Security Administration, in partnership with the Russian Federation, has successfully completed the removal of 14 Russian radioisotope thermoelectric generators, or RTGs, from the Northern Sea Route. These devices, which contain high-activity radioactive sources, powered navigational beacons along Russia’s northern coastline. With this removal, the U.S. Department of Energy has completed its efforts to recover RTGs along the Northern Sea Route, a press release said.

RTGs were used for many years in Russia to generate electrical power at remote locations, including lighthouses and navigational beacons. The 14 RTGs recently recovered by DOE contain more than one million curies of strontium-90, a high-activity radioisotope that could be used in a dirty bomb. [Read more…]
