The Trump administration has requested more money for the U.S. Department of Energy and National Nuclear Security Administration than it did last year, but the impact could vary at Oak Ridge’s major federal sites.

The NNSA, a semi-autonomous agency within DOE, would get a big increase of $2.2 billion, compared to spending levels enacted in fiscal year 2017. The boost would raise NNSA funding to $15.1 billion. The Y-12 National Security Complex in Oak Ridge is an NNSA site.

The NNSA proposal is more than $1 billion higher than the $13.9 billion requested by the Trump administration in fiscal year 2018, which was up $1.4 billion over the fiscal year 2016 spending level ($12.5 billion).

Oak Ridge Today reported last year that Y-12’s funding would have been up 25 percent under President Donald Trump’s budget request for the current fiscal year, if Congress had approved the proposed spending levels. [Read more…]

With some apparent exceptions, employees at the Y-12 National Security Complex in Oak Ridge will continue working even after the federal government shut down after federal funding expired Friday.

Y-12 posted an announcement after the federal government shut down early Saturday. The announcement said workers at Y-12 and the Pantex Plant in Amarillo, Texas, are expected to report to work on their next scheduled work day unless they have previously approved leave or have been given formal notice by their management to not report to work.

A few other federal organizations and federal contractors didn’t immediately appear to have posted notices as of early Saturday afternoon, about 12 hours after the shutdown began. Those include Oak Ridge National Laboratory. [Read more…]

Researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory have received nine R&D 100 Awards in recognition of their significant advancements in science and technology, a press release said. The honorees were recognized in November at the 55th annual R&D 100 Conference, sponsored by R&D Magazine.

The awards, known as the “Oscars of Invention,” honor innovative breakthroughs in materials science, biomedicine, consumer products, and more from academia, industry, and government-sponsored research agencies. This year’s nine honors bring ORNL’s total of R&D 100 awards to 210 since their inception in 1963, the press release said.

ORNL researchers were recognized for the following innovations:

ACMZ Cast Aluminum Alloys were developed by a team of researchers from ORNL with Fiat Chrysler Automobile U.S. and Nemak U.S.A.

ACMZ aluminum alloys are a new class of affordable, lightweight superalloys capable of withstanding temperatures of almost 100-degree Celsius more than current commercial alloys while providing exceptional thermomechanical performance and hot tear resistance.

Common commercial alloys soften rapidly at high temperatures, limiting their use in next-generation vehicles, while other alloys that can withstand elevated temperatures are cost prohibitive and difficult to cast. ACMZ alloys were developed using a suite of atomic-level characterization and computation tools, resulting in a strong, stable, and versatile material capable of withstanding the stressful conditions of next-generation high-efficiency combustion engines, the press release said.

KNOXVILLE—David Millhorn, University of Tennessee senior vice president emeritus and national laboratory relations advisor, died on Monday in Knoxville. Millhorn, who joined UT System Administration in 2005 as vice president for research and economic development, was 72.

In July, Millhorn transitioned to his most recent role with the university after having served as UT senior vice president and vice president for research, outreach, and economic development since 2016 and president of the UT Research Foundation since January 2014.

Two years after Millhorn’s service as a member of the UT president’s staff began in 2005, he took on the additional role of UT executive vice president and served in both that capacity and as vice president for research until 2016, a press release said.

Millhorn oversaw multiple, unprecedented achievements for the university’s research enterprise, the press release said. Among those, UT’s contract with the U.S. Department of Energy to manage Oak Ridge National Laboratory—in partnership with Battelle Memorial Institute of Ohio—earned two five-year extensions, in 2010 and 2015, without having to re-compete.

About half of the uranium-233 waste stored in Building 3019 at Oak Ridge National Laboratory has been shipped to a disposal facility in Nevada.

The shipments were completed in August, said Jay Mullis, manager of the U.S. Department of Energy’s Oak Ridge Office of Environmental Management.

But federal officials were only recently able to announce the end of the shipments of the waste from the Consolidated Edison Uranium Solidification Program, or CEUSP. The waste contained radioisotopes of uranium from a 1960s research and development test of thorium and uranium reactor fuel at the Consolidated Edison Indian Point-1 reactor in New York. The test was sponsored by the Atomic Energy Commission, a predecessor to the U.S. Department of Energy.

The shipments were completed 10 months ahead of schedule, Mullis told the Oak Ridge Site Specific Advisory Board on Wednesday, November 8. The CEUSP waste had been treated and turned into a ceramic matrix. It was shipped from Building 3019 at ORNL, where it had been stored, to the Nevada National Security Site, a former nuclear weapons proving ground about 65 miles northwest of Las Vegas. DOE started shipping the waste materials to the Nevada National Security Site in May 2015.

Former director Alvin Weinberg once called it the greatest technical achievement at Oak Ridge National Laboratory. It was inspired by the campaign to build a nuclear-powered aircraft in the 1950s, and it was the first reactor to ever operate using uranium-233.

Now parts of the Molten Salt Reactor Experiment that are too radioactively “hot” for humans could be entombed in concrete.

For now, the idea is only under study, and there is no guarantee that any part of the Molten Salt Reactor Experiment, a nuclear historic landmark that has been dormant for decades, will be entombed.

But it’s one of the proposals being evaluated by the U.S. Department of Energy’s Oak Ridge Office of Environmental Management. The goal is to finish the evaluation by the end of the year.

Jay Mullis, manager of the Oak Ridge Office of Environmental Management, presented the proposal to the Oak Ridge City Council and Site Specific Advisory Board in two separate meetings earlier this month. The entombment proposal is one of five items being evaluated as part of a 45-day review started by DOE’s Environmental Management, or EM, program in June. [Read more…]
