The federal spending bill approved last week includes $639 million for the federal government’s cleanup program in Oak Ridge, including what could be full funding for a top priority deactivation and demolition project at the Y-12 National Security Complex.

The $639 million for the current fiscal year is an increase of $141 million or more, compared to recent fiscal years, and it’s the most money appropriated in a while.

Besides Y-12, the fiscal year 2018 funding will be used for U.S. Department of Energy cleanup projects at East Tennessee Technology Park (the former K-25 site) and Oak Ridge National Laboratory.

“It’s very positive for us,” said Jay Mullis, manager of the DOE Oak Ridge Office of Environmental Management, or OREM. Mullis gave a brief update at a meeting of the Oak Ridge Reservation Communities Alliance on Monday.

In addition to $125 million to deactivate and demolish the Biology Complex at Y-12, the fiscal year 2018 spending bill includes $17.1 million in funding for the planned Mercury Treatment Facility at Y-12, about $200 million for continued cleanup work at ETTP, and a total of roughly $12 million for the Environmental Management Disposal Facility, or EMDF. That’s a proposed landfill that could be west of Y-12 and accept waste from future cleanup work at Y-12 and ORNL, possibly early in the 2020s. The project plan for EMDF is expected to be open to public comment later this summer. [Read more…]

A contract between two companies that have operations or employees in Oak Ridge will support continued work on the production of fuel for advanced nuclear reactors, possibly within six years or so.

The two companies, Centrus Energy Corp. and X Energy LLC, announced the services contract in a press release on Wednesday.

The companies had announced in September that they were exploring a collaboration for the possible production of fuel for advanced nuclear reactors, and they had signed a memorandum of understanding for the potential collaboration.

They said then that they were working toward the development of a fuel fabrication facility that could possibly be in Oak Ridge, where Centrus, formerly known as USEC, has had operations for about 15 years. Oak Ridge could be a nexus for the advanced reactor industry in the United States, one official said at the time. It’s not clear yet how large the fuel fabrication facility would be or what the total investment might be.

In the Wednesday press release, the two companies said the services contract announced this month builds upon the September memorandum of understanding.

“This contract is the initial implementation of that agreement,” said Jeremy Derryberry, Centrus senior communications manager. “Our team in Oak Ridge will be working with X-energy on this project.” [Read more…]

For the first time in 30 years, spent nuclear fuel from the High Flux Isotope Reactor at Oak Ridge National Laboratory has been dissolved at the Savannah River Site in South Carolina.

The work is important because it is expected to allow the reactor, known as HFIR, to continue its mission, according to the U.S. Department of Energy Office of Environmental Management.

HFIR, which uses highly enriched uranium, is one of the world’s most powerful nuclear research reactor facilities. It’s the highest flux reactor-based source of neutrons for research in the United States. Flux refers to the rate of flow of fluids, particles, or energy. In HFIR’s case, the flux is measured in neutrons per square centimeter per second. HFIR is used for neutron scattering and isotope production, among other missions.

ORNL will reach its maximum capacity for storing HFIR fuel in fiscal year 2020, the DOE Office of Environmental Management, or EM, said in an “EM Update” electronic newsletter on Tuesday. [Read more…]

The supercomputer being built at Oak Ridge National Laboratory could change the race for supercomputing supremacy between the United States and China, U.S. Representative Chuck Fleischmann said during a budget hearing on Thursday.

The congressman said Summit, a 200-petaflop supercomputer at ORNL, will be commissioned this summer, and it will be the fastest supercomputer in the world, with twice the power of the top Chinese system. The Chinese machine is a 93-petaflop system known as Sunway TaihuLight.

During Thursday’s budget hearing, which featured Energy Secretary Rick Perry, Fleischmann said the United States and China are in a race for supercomputing supremacy. The race is critical to advances in science and technology that will drive economic growth, said Fleischmann, a Republican whose district includes Oak Ridge.

Citing a February 9 edition of Science magazine, Fleischmann said the U.S. dominated supercomputer rankings for decades but is now far behind. The combined power of the top two machines in China easily outpaces all 21 supercomputers operated by the U.S. Department of Energy, the country’s top funder of supercomputers, the congressman said.

But that could change with the commissioning of Summit this summer, Fleischmann said. [Read more…]

Robertsville Middle School in Oak Ridge is the first middle school to ever be selected for a NASA program that launches small cube-shaped satellites into space.

On Friday, the $70,000 science project, which started about three years ago, got a $15,000 boost from Oak Ridge National Laboratory.

The Robertsville satellite, which will orbit a few hundred miles above Earth, will use a small camera to try to take pictures of forest regrowth in the Great Smoky Mountains near Gatlinburg. That area burned in forest fires fed by high winds after Thanksgiving 2016, killing 14 people and damaging or destroying more than 2,500 homes and businesses.

The RMS satellite, named RamSat, will use a radio to relay its images and other data back to Earth.

A project proposal was submitted to NASA in November, and Oak Ridge Schools learned this month that the RMS proposal had been accepted.

“This is such an exciting opportunity for the students!” said Peter Thornton, one of the RamSat team leaders from ORNL. “They will now have the chance to design, build, carry out, and own a satellite mission.” [Read more…]

The Oak Ridge City Council has a special meeting at 4 p.m. today (Friday, February 16) to consider two contracts, one for water line repair and the other for pool repair. The water line repair is an emergency repair to a 24-inch feed that is considered critical for Oak Ridge National Laboratory and passes through the Y-12 National Security Complex.

If approved, the water line repair contract would be valued at roughly $100,000, and it would be awarded to Hurst Excavating LLC of Knoxville. The project would replace about 400 feet of the 24-inch water line, which is along Bear Creek Road inside the Y-12 National Security Complex.

The project is a joint effort between the City of Oak Ridge and the U.S. Department of Energy, Oak Ridge Public Works Director Shira A. McWaters said in a February 15 memo to City Manager Mark Watson. The city-DOE water contract specifies that repairs are to be shared 50/50, McWaters said.

The cast iron water line runs from east to west from the city’s water treatment plant, which is on Pine Ridge at Y-12, to Oak Ridge National Laboratory. The line failed January 29. It is part of the infrastructure that was transferred to the city in May 2000, when the city assumed ownership and began operating the water treatment plant, which had previously been owned by DOE.
