Nuclear energy expert to give FORNL lecture on Tuesday

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.

Summit at ORNL remains No. 2 in world

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.

International fusion energy project to be discussed

David Rasmussen

 

An international fusion energy project that involves Oak Ridge National Laboratory will be discussed in an online meeting on Wednesday, May 19.

The featured speaker will be David Rasmussen, the leader of the technical integration of the U.S. contributions to the international fusion project, which is under construction in France and known as ITER.

Rasmussen’s areas of responsibility have included the ITER plasma heating and fueling systems, a press release said. He has been a plasma research scientist at ORNL since 1981. He has more than 35 years of fusion and plasma science experience in diagnostic measurements and the technology development needed for magnetic confinement fusion and other plasma technology applications, the release said. Rasmussen received a Ph.D. in applied science, specializing in plasma physics, from the University of California at Davis in 1981 where his graduate work was a study of inertial laser fusion wave plasma interactions.

The May 19 talk is hosted by ORION, an amateur science and astronomy club based in Oak Ridge. The talk is scheduled to begin on Zoom at 7 p.m. May 19, and it is open to the public. If you are interested in joining, the Zoom meeting ID is 885 2873 5960, and the passcode is 716689.

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.

National Park Service asks for public comments about Manhattan Project Park

An undated aerial photo posted online by the U.S. Department of Energy Oak Ridge Office of Environmental Management shows the former K-25 Building, once the world’s largest building, in west Oak Ridge. The building has been demolished, but its history is being preserved, including at the new K-25 History Center.

The National Park Service is asking for public comments about the Manhattan Project National Historical Park. The comments are being sought as the Park Service prepares an interpretive plan for park programming, exhibits, and media, a press release said. The goal is to capture many different experiences and perspectives.

Discussions with the public are being organized by theme and region. The discussions focused on regions concentrate on the areas around the three Manhattan Project park locations: Hanford, Washington; Los Alamos, New Mexico, and Oak Ridge, Tennessee. Because of COVID-19, all events will be held virtually (online), the press release said.

The public meetings are Tuesday to Thursday this week. Here is the schedule:

“A Tribute to Alvin Weinberg,” including information on the new online database of his scientific publications and other documents, will be presented virtually to the public from 7 to 8 p.m. Tuesday, April 20 (Weinberg’s birth anniversary).

The presentation, via Zoom, is sponsored by the Children’s Museum of Oak Ridge and Friends of Oak Ridge National Laboratory.

“The purpose of this public online event is to honor Alvin Weinberg’s legacy and to celebrate the preservation and digitization of his papers,” said Rhonda Bogard, who led the digitization of the papers, most of which were initially donated to the Children’s Museum in 1986. [Read more…]
