About 600 experiments and roughly 500 users were affected by the nearly year-long shutdown of the High Flux Isotope Reactor at Oak Ridge National Laboratory, the lab said Thursday.

HFIR, which is used for research and isotope production, restarted October 29, 2019. It had been shut down since November 13, 2018, after an elevated radiation leve l was detected in the reactor’s primary cooling system.

Reactors users who had approved proposals when HFIR was shut down have been running those experiments since it restarted in the fall, according to a response to questions provided by ORNL spokesperson Morgan McCorkle on Thursday. The backlog is expected to be completed by the spring.

The shutdown did not affect the production of plutonium-238, but it did delay the production and distribution of some medical and industrial isotopes, the lab’s response said.

Construction is planned in December for a project to upgrade proton power at the Spallation Neutron Source at Oak Ridge National Laboratory.

The construction could last about one year, and it will be limited to the buildout of what is known as the klystron gallery, ORNL said in June. The klystron gallery houses the radio-frequency systems that power the structures used to accelerate a negatively-charged hydrogen ion beam in the linear accelerator at SNS.

SNS generates neutrons for scientific research by propelling protons down a linear accelerator. When the protons collide with a liquid mercury target, they create a “spall” of neutrons that are sent down beam lines surrounded by research instruments.

The proton power upgrade will eventually double the power of the SNS proton beam from 1.4 megawatts to 2.8 megawatts. The current total estimated project cost is $245 million.

The U.S. Department of Energy on Tuesday announced a contract with Cray Inc. to build the Frontier supercomputer at Oak Ridge National Laboratory. It is expected to be the world’s most powerful supercomputer when it debuts in 2021.

The contract with Cray is valued at more than $600 million for the system and technology development, a press release said.

Energy Secretary Rick Perry was at ORNL on Tuesday morning to make the announcement.

“This is a big deal,” Perry said. “Frontier’s record-breaking performance will ensure our country’s ability to lead the world in science that improves the lives and economic prosperity of all Americans and the entire world. Frontier will accelerate innovation in AI (artificial intelligence) by giving American researchers world-class data and computing resources to ensure the next great inventions are made in the United States.”

Besides the supercomputing announcement on Tuesday, Perry also delivered the keynote speech at InnovationXLab: Advanced Manufacturing Summit at ORNL.

Frontier is expected to perform at greater than 1.5 exaflops. It will be able to solve calculations up to 50 times faster than today’s top supercomputers, exceeding a quintillion, or 10¹⁸, calculations per second, the press release said. That’s a billion billion calculations per second.

Oak Ridge Today has previously reported that Frontier would be built at ORNL. But the contract with Cray and its value and the specific performance estimate of more than 1.5 exaflops are all new announcements. The contract award includes technology development funding, a center of excellence, several early-delivery systems, the main Frontier system, and multi-year systems support. The Frontier system is expected to be delivered in 2021, and acceptance is expected in 2022.

(For members) Three national labs building exascale computers

Posted at 6:39 pm February 4, 2019

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.

Oak Ridge National Laboratory is adding a three-story office and laboratory building on its central campus.

It would be the first time a building of this size has been added at ORNL since the Chemical and Materials Science building (Building 4100) was completed in 2011, spokesperson Morgan McCorkle said in a response to questions Thursday.

She said the new building will be located in the central part of the main ORNL campus between buildings 3500 and 3525.

“The facility will offer state-of-the-art laboratory space and offices to support a range of research activities, including growing missions in computing and materials science and development,” McCorkle said. “The space can be adapted to serve the needs of changing scientific programs and priorities.” [Read more…]

Starting in December, Oak Ridge National Laboratory and Y-12 National Security Complex will both manage their own security forces to protect their sites.

Y-12 has been managing its own protective force for about six years, ever since a former contractor, B&W Y-12, terminated a contract with WSI Oak Ridge after a security breach at the 811-acre plant. The current Y-12 contractor, Consolidated Nuclear Security LLC, confirmed this month that it has been responsible for security and security police officers since it began managing and operating the plant in July 2014.

On Friday, UT-Battelle, which manages and operates ORNL for the U.S. Department of Energy, said it is assuming responsibility for providing protective force services at the laboratory starting December 30. That’s when a new security contractor will take over at some federal sites in Oak Ridge.

ORNL Media Relations Manager Morgan McCorkle said about 90 employees who have been providing security services at ORNL under a contract with National Strategic Protective Services LLC will transition from NSPS to UT-Battelle. [Read more…]

There has been strong interest in a voluntary separation program that could reduce the workforce at Oak Ridge National Laboratory by up to 350 positions, but the lab still has to review applications and finalize who qualifies, a spokesperson said Wednesday, the deadline to apply.

The laboratory is still in the middle of reviewing the applications and determining who qualifies, said Morgan McCorkle, ORNL communications media manager.

The workforce could be reduced by up to 350 positions through both voluntary and involuntary separations.

“We still expect to use both mechanisms,” McCorkle said.

The 350-position reduction would decrease the workforce of 4,800 employees by about 7.3 percent. The workforce reduction, which is expected to be completed by the end of this year, was announced by ORNL Director Thomas Zacharia in an August 8 email to employees. [Read more…]

The workforce reduction of up to 350 positions at Oak Ridge National Laboratory is expected to decrease personnel costs by about $34 million each year, and the lab expects most of those who apply for voluntary separations from the lab to be of retirement age, a spokesperson said Wednesday.

The workforce reduction, which is expected to be completed by the end of this year, was announced by new ORNL Director Thomas Zacharia in a Tuesday morning email to employees.

The lab hopes to reduce its workforce of 4,800 employees by about 7.3 percent (350 positions) using voluntary separations. Involuntary separations will be used if necessary.

On Wednesday, ORNL spokesperson Morgan McCorkle said the lab plans to reduce about 250 overhead positions and 100 research and development jobs. Overhead jobs are those not directly related to research. The research and development staff who will be eligible for voluntary separations are those who charge more than half of their time to overhead accounts or whose program budgets were reduced in fiscal year 2017, McCorkle said.

A specific breakdown of the affected jobs is not yet available. [Read more…]

ORNL to reduce workforce by up to 350 by end of year

Oak Ridge National Laboratory will reduce its workforce by up to 350 positions by the end of the calendar year, ORNL Director Thomas Zacharia said in a Tuesday morning email to employees.

The workforce restructuring plan has been proposed by UT-Battelle and approved by the U.S. Department of Energy, Zacharia said. ORNL is DOE’s largest multiprogram science and energy laboratory.

“From time to time, sustaining our work effectively and efficiently requires the most difficult of decisions, which is to reduce our staff in certain areas of the lab,” Zacharia said. “To allow us to provide for our research missions and to allocate resources most productively, the Department of Energy has approved a Workforce Restructuring Plan proposed by UT-Battelle that will reduce ORNL’s workforce by up to 350 positions by the end of the calendar year.”

Zacharia said the reductions will be made primarily among staff who charge to “indirect accounts,” along with some research staff affected by fiscal year 2017 funding who could not be placed elsewhere in the lab.

“By reducing these positions, ORNL will be able to maintain competitive chargeout rates while freeing resources for discretionary investments that will modernize lab infrastructure and maintain core research capabilities in the mission areas assigned to ORNL,” Zacharia said. [Read more…]

Oak Ridge National Laboratory on Wednesday said it is building the world’s smartest supercomputer.

The new supercomputer is called Summit. It will be located in a new data center next to Titan, which is now the fourth most powerful supercomputer in the world.

Summit will be 5-10 times faster than Titan, ORNL said. It will move data five to 10 times faster, store eight times more data, and perform many more calculations simultaneously than Titan, the lab said in information provided by spokesperson Morgan McCorkle.

Summit will be the world’s smartest supercomputer because of its enormous memory and data handling capabilities as well as its unique machine learning processor design, McCorkle said.

“The first of Summit’s cabinets arrived Monday, and our team is in the process of uncrating and putting them in place,” McCorkle said in response to questions from Oak Ridge Today. [Read more…]
