John Bates, independent consultant for battery development and former researcher at Oak Ridge National Laboratory, will speak about solid-state lithium and lithium-ion batteries on Tuesday, Aug. 10, at 12 noon to Friends of ORNL. The lecture is open to the public. To view the virtual lecture, click on the talk title on the homepage of the www.fornl.org website and click on the Zoom link on the page describing the lecture.

“I will give a brief history of the development of intercalation cathode materials such as lithium cobalt oxide and a review of some of the research on thin-film batteries at ORNL and other organizations,” Bates said. “I will list a few of the perceived applications of these batteries for powering small devices. Successful commercialization of thin-film batteries encourages the view that the daunting problems facing large-scale solid-state batteries are solvable but perhaps not as soon as advertised.” [Read more…]

The biggest change for a water discharge permit drafted for the Y-12 National Security Complex is the construction and operation of a Mercury Treatment Facility, a state official said Tuesday.

The mercury treatment facility, which is under construction and could begin operating next year, is expected to capture and treat most of the mercury released as old, unused mercury-contaminated buildings, equipment, and soils are demolished and removed, especially on the west side of the nuclear weapons production site.

Millions of pounds of mercury were used at Y-12 in the 1950s and early 1960s to produce nuclear weapons parts. Roughly 60,000 pounds is estimated to remain in buildings and equipment, and an unknown amount was released into soils and sediments. About 1.3 million pounds is unaccounted for. Mercury is a top pollutant of concern on the federal Oak Ridge Reservation.

Andrew Worrall

Andrew Worrall, deputy director of Gateway for Accelerated Innovation in Nuclear (GAIN) and section head at the Oak Ridge National Laboratory, will present “Why Nuclear and Why Now?” on Tuesday, July 13, at noon to Friends of ORNL. The lecture is open to the public. To view the virtual lecture, click on the talk title on the homepage of the www.fornl.org website and click on the Zoom link on the page describing the lecture, a press release said. Today, nuclear energy in the United States produces approximately 20 percent of the nation’s electricity demand, the press release said. According to Worrall, “It is the largest producer of our nation’s emission-free electricity, yet is often misunderstood and misrepresented.” In his presentation, Worrall will highlight some of the “pros and cons” of nuclear energy. Then he will explain why an expansion in nuclear energy is required not just for the United States but also around the world as the earth’s surface temperature continues to rise in response to increasing greenhouse gas emissions.

More than 4,000 fish and crayfish were killed by chlorinated water and mercury at the Y-12 National Security Complex in two series of incidents in 2018 and 2021. 

The first series of incidents was likely caused by the release of mercury while crews were cleaning up and removing equipment at the Alpha-4 Building on the west side of Y-12, according to scientists and officials. Alpha-4 is the most contaminated of the four major mercury-contaminated buildings at Y-12. Millions of pounds of mercury were used at Y-12 decades ago to produce nuclear weapons parts. Removing mercury-contaminated buildings, equipment, and soil remains one of the top challenges of cleaning up the Oak Ridge Reservation.

The Summit supercomputer at Oak Ridge National Laboratory remains the fastest supercomputer in the United States and the second most powerful in the world.

Summit, an IBM system, was the world’s most powerful supercomputer from June 2018 to November 2019, when the U.S. Department of Energy had the two fastest systems in the world.

DOE still has two of the three fastest supercomputers, Summit at ORNL and Sierra at Lawrence Livermore National Laboratory in Livermore, California. And it has three of the top five systems in the world. DOE has a new supercomputer, Perlmutter, ranked at number five. It’s at the National Energy Research Scientific Computing Center at the Lawrence Berkeley National Laboratory, in Berkeley, California. Perlmutter was the only new system in the top 10 in the semiannual TOP500 list released Monday.

Summit was bumped from the top spot on the TOP500 list by a Japanese supercomputer, Fugaku, in June 2020.

Fugaku, which is in Kobe, Japan, remained in the top spot on the TOP500 list released in November and again on the list released Monday. The TOP500 list uses a benchmark test to rank the world’s most powerful supercomputers.

Demolition work at a former radioisotope laboratory in Oak Ridge could be complete this spring.

The U.S. Department of Energy Oak Ridge Office of Environmental Management and UCOR announced earlier this year that UCOR, a contractor, had begun removing the two remaining structures at the former Radioisotope Development Lab at Oak Ridge National Laboratory.

“This project launches our next phase of major demolition and cleanup at ORNL,” said Nathan Felosi, OREM’s portfolio federal project director for ORNL. “Our work is eliminating contaminated structures, like this one, that are on DOE’s list of high-risk facilities and clearing space for future research missions.”

Known as “hot cells,” the structures being demolished are heavily shielded concrete rooms that provided researchers protection from highly radioactive material during the years the laboratory was operational, a press release said.
