Three national laboratories, including Oak Ridge National Laboratory, are building new computer systems that could be many times more powerful than today’s top supercomputers.

The new machines are exascale systems. None have been delivered yet, but the planning for them started more than a year ago and the new high-performance systems could be delivered to the three laboratories in the next several years. Planning for the exascale computers was under way even before the world’s most powerful supercomputer, a petaflop system called Summit at ORNL, was unveiled in June 2018.

Exascale computers could be 50 to 100 more powerful than today’s petaflop computers, according to the U.S. Department of Energy. Besides ORNL, they could be located at Argonne National Laboratory southwest of Chicago and Lawrence Livermore National Laboratory east of San Francisco. The first system is expected at Argonne, followed by a second system at ORNL.

UCOR, the federal government’s cleanup contractor in Oak Ridge, will be closed Tuesday because of the weather.

“Only essential personnel should report,” UCOR said in a post published on Twitter.

The closure applies to UCOR employees at the East Tennessee Technology Park, Oak Ridge National Laboratory, Y-12 National Security Complex, and “offsite locations,” UCOR said. [Read more…]

U.S. nuclear forces could cost about $494 billion during a 10-year period if current plans are followed, according to the nonpartisan Congressional Budget Office.

The CBO is required by law to estimate the 10-year costs every two years. The new estimate is $494 billion for work between 2019 to 2028, the CBO said in a report published this month. That’s an average of just under $50 billion a year.

The Y-12 National Security Complex in Oak Ridge participates in the nuclear weapons work along with other U.S. Department of Energy sites and the U.S. Department of Defense.

The CBO said nuclear weapons have been an important part of U.S. national security since they were developed during World War II. Oak Ridge was the main production site for the top-secret project to build those first weapons, and Y-12 continues to work on nuclear weapons. One modernization program for the W76-1 warhead was recently completed, and another for the B61-12 bomb has started.

The CBO said nuclear forces were central to U.S. defense policy during the Cold War, and a large arsenal was built. [Read more…]

ORAU on Friday reported that the partial shutdown of the federal government has had, for the most part, a minimal impact on its operations.

The partial government shutdown is now in its 35th day. It’s the longest shutdown ever, and it includes about 25 percent of the federal government.

ORAU has a customer base that includes more than 20 federal agencies.

“The impact to date has been varied, but for the most part minimal,” ORAU spokesperson Pam Bonee said in an emailed response to questions on Friday. “The majority of our work is funded or had sufficient funds to carry the work into the first quarter of 2019.” [Read more…]

Crews start project to reduce maintenance, operations costs at Molten Salt Reactor

Cleanup crews started a $4.7 million project this month to reduce maintenance and operations costs at the Molten Salt Reactor Experiment, which was shut down 50 years ago at Oak Ridge National Laboratory.

The project is expected to save nearly $25 million in costs, the U.S. Department of Energy Office of Environmental Management said in an “EM Update” published Tuesday.

The cost-reduction project will relocate employees stationed at the decades-old facility. Personnel currently housed in the building will move to other site locations to help with other projects, the “EM Update” said.

The project is expected to enhance the facility’s electrical distribution, sump pump, fire suppression, and monitoring systems.

“Although it was shut down 50 years ago, certain systems within the reactor building have continued to operate to keep the facility safe and stable until it can be demolished,” said the “EM Update,” with the Oak Ridge story contributed by Mike Butler. [Read more…]

Y-12: Work complete on W76-1 warhead program

After two decades, work was completed in December on a program to extend the life of the W76 nuclear warhead, the Y-12 National Security Complex said on Monday.

That ended a decade of work to extend the service life of the original warhead design by 40 years, Y-12 said.

“This warhead plays a vital role in maintaining the nation’s credible nuclear deterrent,” said Consolidated Nuclear Security LLC, which manages and operates Y-12 for the National Nuclear Security Administration.

The Life Extension Program, or LEP, is for the W76-1 warhead. The W76-1 is a refurbished W76-0 warhead. The W76-0 warhead is a submarine-launched ballistic missile system that was first introduced into the stockpile for the U.S. Navy in 1978. The warhead is deployed with Trident II D5 missiles on Ohio-class nuclear ballistic missile submarines. [Read more…]

Canned subassembly certified four months ahead of schedule

The Y-12 National Security Complex on Monday said it has completed a major milestone in efforts to refurbish components for a strategic nuclear weapons system that is vital to the U.S. nuclear deterrent.

The first production unit for a bomb called the B61-12 was certified at Y-12 on December 6, 2018.

The work is part of the B61 Life Extension Program, or LEP. The B61 is a nuclear bomb that can be carried on several types of military aircraft. The B61 LEP will extend the life of this strategic weapon for 20 years, said Consolidated Nuclear Security LLC, which manages and operates Y-12 for the National Nuclear Security Administration.

B61 bombs are the oldest nuclear weapons in the nation’s active stockpile. They have been in service almost 50 years, and critical components of the bombs are reaching the end of their operational lives. The B61 was first “fielded” in 1968, and current modifications were fielded between 1979 and 1991, according to the U.S. Government Accountability Office. [Read more…]

The partial shutdown of the federal government does not affect state oversight of the federal cleanup program in Oak Ridge, a state official said Thursday.

At this time, the federal shutdown has no impact on the Tennessee Department of Environment and Conservation, said Kim Schofinski, TDEC deputy communications director. That means state oversight of the Oak Ridge cleanup program is not currently affected. The Oak Ridge sites include East Tennessee Technology Park (the former K-25 site), Oak Ridge National Laboratory, and Y-12 National Security Complex. [Read more…]
