The Manhattan Project National Historical Park will ring the International Friendship Bell 76 times on Friday morning, August 6, to commemorate the effects of the atomic bombing of Hiroshima 76 years ago.

The bomb was dropped on Hiroshima, Japan, at 8:15 a.m. on August 6, 1945. It was the first atomic bomb used in war and the first of two dropped on Japan near the end of World War II. Uranium for the first bomb, which was code-named “Little Boy,” was enriched in Oak Ridge. The bomb had about 140 pounds of uranium fuel and had an explosive force equivalent to 15,000 tons of TNT, according to Atomic Heritage. Between 90,000 and 166,000 people are believed to have died from the 10-foot, 9,700-pound bomb in the four-month period following the explosion, Atomic Heritage said.

The National Park Service is calling the August 6 ceremony “Days of Peace and Remembrance.”

“During this silent event, we will be requesting visitors to come up and ring the bell,” a press release said. “Visitors will be able to write down their own hopes and messages of peace.”

The United States dropped a second atomic bomb, a plutonium-fueled weapon, on Nagasaki, Japan, on August 9, 1945, three days after the Hiroshima bombing. It had about 13.6 pounds of plutonium fuel and an explosive force equivalent to 21,000 tons of TNT. About 80,000 Japanese died by the end of 1945 because of that bomb, which was called “Fat Man,” Atomic Heritage said.

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.

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.

The waste shipped from the Y-12 National Security Complex that violated a solid waste permit in Nevada included small volumes of pressurized, non-flammable gases and an energetic material, but the shipments did not pose a safety risk, the U.S. Department of Energy said Thursday.

“These items were contained within a sealed, thick steel assembly that was disposed within a large metal box,” DOE said in response to questions. “Though the presence of these internal items were not known at the time of disposal, they do not pose any safety risk because the inner assembly is capable of containing any release of the small volumes of pressurized gases and the energetic material.”

On Thursday, Nevada announced details of the settlement agreement with the U.S. Department of Energy over low-level radioactive waste that was incorrectly identified and shipped from Y-12 National Security Complex in Oak Ridge to DOE’s Nevada National Security Site northwest of Las Vegas between 2013 and 2018.

Oak Ridge Today first reported about the settlement agreement on Wednesday. The Nevada announcement on Thursday provided additional information.

Here is Nevada’s announcement:

The U.S. Department of Energy, National Nuclear Security Administration, and Nevada environmental regulators have agreed to a settlement after classified low-level waste shipped west from the Y-12 National Security Complex allegedly violated waste acceptance criteria at the Nevada National Security Site northwest of Las Vegas, according to documents posted online. 

For members: More than 4,000 fish, crayfish killed by Y-12 chlorinated water, mercury

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.
