HARDIN VALLEY—He once called for eliminating the U.S. Department of Energy, but after touring federal sites in Oak Ridge and Hardin Valley on Monday, new Energy Secretary Rick Perry pledged to be an advocate for at least some programs.

Perry, a former Texas governor who was confirmed as energy secretary on March 2, was asked about his comments calling for the elimination of three federal departments, including DOE, during the 2012 presidential campaign. His call to eliminate the three departments probably received more attention than it might have otherwise because, in a moment that received a lot of attention, Perry couldn’t recall the name of the Department of Energy during a November 2011 debate. Some believe that moment helped sink his presidential campaign.

Earlier this year, Perry told U.S. senators during his confirmation hearing that he regretted his earlier call to eliminate DOE. After being briefed on many vital functions of DOE, he no longer believed that it should be eliminated, Perry told the Senate Energy and Natural Resources Committee, according to The New York Times.

During a stop in Hardin Valley on Monday afternoon, Perry acknowledged he’s learned a lot since the 2012 campaign, including in his visit to Oak Ridge and at DOE headquarters in Washington, D.C., and in trips to Idaho National Laboratory and the Waste Isolation Pilot Plant in southeast New Mexico.

He suggested he might not be the only one unaware of some of the innovations that have roots in or are developed in places like Oak Ridge, innovations like gene therapy, supercomputing, and 3D printing. The American public may also not be aware of how that “cutting-edge” technology can be used to create jobs and wealth, Perry said.

“Those are things I readily admit I didn’t know five years ago,” Perry said after operating a 3D-printed excavator and test-driving a printed utility vehicle—and learning about other innovations such as supercomputers at Oak Ridge National Laboratory and composite work at its Manufacturing Demonstration Facility in Hardin Valley on Monday afternoon. “There are a lot of things that have surprised me.” [Read more…]

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…]

Name of new element, tennessine, recognizes state’s contributions, including at ORNL

The recently discovered element 117 has been officially named “tennessine” in recognition of Tennessee’s contributions to its discovery, including the efforts of the U.S. Department of Energy’s Oak Ridge National Laboratory and its Tennessee collaborators at Vanderbilt University and the University of Tennessee.

“The presence of tennessine on the Periodic Table is an affirmation of our state’s standing in the international scientific community, including the facilities ORNL provides to that community as well as the knowledge and expertise of the laboratory’s scientists and technicians,” ORNL Director Thom Mason said in a press release.

The International Union of Pure and Applied Chemistry, or IUPAC, gave its final approval to the name “tennessine” following a year-long process that began December 30, 2015, when IUPAC and the International Union of Pure and Applied Physics announced verification of the existence of the superheavy element 117. That was more than five years after scientists first reported its discovery in April 2010.

IUPAC validates the existence of newly discovered elements and approves their official names.

ORNL had several roles in the discovery, the most prominent being production of the radioisotope berkelium-249 for the search. [Read more…]

Soon to be deployed at the U.S. Department of Energy’s Oak Ridge National Laboratory is an experiment to explore new physics associated with neutrinos. The Precision Oscillation and Spectrum Experiment, or PROSPECT, is led by Yale University and includes partners from 14 academic and governmental institutions. The DOE High Energy Physics program will support the experiment at the High Flux Isotope Reactor, or HFIR, a DOE Office of Science User Facility at ORNL. The neutrino, the subject of a 2015 Nobel Prize, remains a poorly understood fundamental particle of the Standard Model of particle physics.

These electrically neutral subatomic particles are made in stars and nuclear reactors as a byproduct of radioactive decay processes. They interact with other matter via the weak force, making their detection difficult. As a result of this elusiveness, neutrinos are the subject of many interesting and challenging detection experiments, including PROSPECT.

“Unique capabilities of ORNL will enable us to broaden the understanding of neutrino properties,” said David Dean, director of ORNL’s Physics Division. “The expansion of neutrino experiments at Oak Ridge National Laboratory is a win for the lab because we have a new scientific focus area, and a win for the scientific community because ORNL has unique neutrino sources that physicists will utilize to explore neutrino science.” [Read more…]

Tennessine is among the names proposed for four new elements. If approved, the name would recognize the contributions of Tennessee research centers—Oak Ridge National Laboratory, Vanderbilt University, and the University of Tennessee—in the discovery of one of four new superheavy elements: 113, 115, 117, and 118.

Tennessine (Ts) is proposed for element 117.

The discovery of the four new elements was announced in January, and Oak Ridge National Laboratory played a role in discovering two of them. The elements have been added to the periodic table, filling the seventh row, or period.

Twenty-two milligrams of a very pure synthetic material produced at ORNL were used in the discovery of two of the new chemical elements. [Read more…]

Twenty-two milligrams of a very pure synthetic material produced at Oak Ridge National Laboratory were used in the discovery of two new chemical elements that will help fill out the seventh row of the periodic table.

The synthetic element, berkelium-249, was produced in a project that started with a six-month irradiation of a target material at the High Flux Isotope Reactor at ORNL. The resulting product was separated and processed during a three-month period at the lab’s Radiochemical Engineering Development Center.

The berkelium-249 was then shipped to the Joint Institute for Nuclear Research, or JINR, in Dubna, Russia, where it was intensely bombarded, or irradiated, with calcium-48 ions, creating six atoms of element 117, said Jim Roberto, ORNL associate lab director for science and technology partnerships. Berkelium-249, which does not exist in nature, has a 300-day lifetime, so researchers had a short time to do their experiments.

Element 117 is one of four new elements that have been officially verified by the International Union for Pure and Applied Chemistry. The IUPAC announced the discoveries on December 30. The other three are elements 113, 115, and 118. Element 115 is produced when element 117 decays. [Read more…]

With the production of 50 grams of plutonium-238, researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory have restored a U.S. capability dormant for nearly 30 years and set the course to provide power for NASA and other missions.

Plutonium-238 produces heat as it decays, and it can be used in systems that power spacecraft instruments. The new sample, which is in the same oxide powder form used to manufacture heat sources for power systems, represents the first end-to-end demonstration of a plutonium-238 production capability in the United States since the Savannah River Plant in South Carolina ceased production of the material in the late 1980s.

Researchers will analyze the sample for chemical purity and plutonium-238 content, then verify production efficiency models and determine whether adjustments need to be made before scaling up the process.

“Once we automate and scale up the process, the nation will have a long-range capability to produce radioisotope power systems such as those used by NASA for deep space exploration,” said Bob Wham, who leads the project for the lab’s Nuclear Security and Isotope Technology Division. [Read more…]
