Tennessee Governor Bill Haslam visited the U.S. Department of Energy’s Oak Ridge National Laboratory on Friday to congratulate the ORNL team involved in the discovery of the element tennessine, named in recognition of the vital contributions of the state of Tennessee to the international search for new superheavy elements.

UT-Battelle, the managing contractor of ORNL, is marking the discovery by providing more than 1,000 public middle schools and high schools in Tennessee with new charts of the periodic table. Tennessine—the official name for element 117—completes the seventh row of the table and the column of elements classified as halogens.

The charts will include the signatures of Haslam and ORNL Director Thom Mason.

“We had two very significant announcements in Tennessee this fall as it relates to science,” Haslam said. “In October, the Nation’s Report Card announced that Tennessee students are the fastest improving in the nation in science, and in November, Tennessee became only the second state to be recognized in the periodic table of elements. Having an element named in our honor is further evidence of the scientific excellence that exists at Oak Ridge National Laboratory, the University of Tennessee, Vanderbilt University, and other institutions throughout our state, and by UT-Battelle donating new periodic tables to every middle and high school in Tennessee, students can feel proud of our state’s important role in the scientific community and inspired to play a role in its future.” [Read more…]

The High Flux Isotope Reactor, or HFIR, now in its 48th year of providing neutrons for research and isotope production at Oak Ridge National Laboratory, has been designated a Nuclear Historic Landmark by the American Nuclear Society.

“This designation from the ANS recognizes HFIR’s role in the history of the nuclear age, but it also speaks to the excellence of its design and operation,” ORNL Director Thom Mason said. “HFIR remains one of the world’s most capable reactor-based neutron science, radioisotope production, and materials irradiation facilities, and we expect that to continue for many years.”

The designation was proposed by the ANS honors and awards committee and approved on initial ballot by the board of directors.

“The ANS Nuclear Historic Landmark signifies that a nuclear facility has played an important role in nuclear science and engineering,” ANS President Michaele C. Brady Raap said. “HFIR, with its preeminent role in isotope production and neutron science, certainly meets that criteria.”

The reactor was conceived in the late 1950s as a production reactor to meet anticipated demand for transuranic isotopes (“heavy” elements such as plutonium and curium). HFIR today is a U.S. Department of Energy Office of Science User Facility and one of the world’s sole sources of the radioisotope californium-252, used in industry and medicine. ORNL is a DOE lab.

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…]

ORNL starts new six-year californium-252 production contract

The Oak Ridge National Laboratory—home of one of only two reactor facilities in the world capable of producing californium-252 (Cf-252)—has begun implementing a new six-year contract between the U.S. Department of Energy Isotope Program and industry to make this unique and versatile radioisotope.

The new contract follows the successful completion of a four-year Cf-252 program under an agreement with a consortium of industries that use the neutron-emitting radioisotope for a number of applications that focus mostly on analysis, detection, and nuclear energy.
