Four workers received small external radiation doses and a planned outage of the Spallation Neutron Source was started a few days early after an unexpected “pressure transient” in March, according to Oak Ridge National Laboratory.

The low radiation dose levels (less than 25 millirem) were well below the regulatory threshold of 5,000 mrem annual exposure, which was established to protect worker safety, ORNL said in June.

The pressure transient occurred in the SNS mercury loop. When radiation was detected, ORNL staff closed off the affected area and reviewed workers’ dosimeters.

“Readings showed four workers received small external doses, none more than 25 millirem,” ORNL said.

For comparison, a chest x-ray produces a radiation dose of about 6 mrem; a mammogram about 13 mrem, and a head and chest CT scan is 1,100 mrem[1].

No injuries were reported during a fire at a transformer for a salt bath used to heat depleted uranium at the Y-12 National Security Complex in May.

The transformer fire was reported Monday, May 20, in Building 9215 at Y-12. It burned no more than about 25 minutes, according to the Defense Nuclear Facilities Safety Board. No depleted uranium was being processed at the time of the fire, the board said.

The salt bath heats depleted uranium before metalworking operations.

The DNFSB said the system engineer had stepped away from the salt bath while it was slowly heating to a new temperature, and he noticed the fire after re-entering the area after a supervisor told him about an unusual odor, the DNFSB said. The engineer called 911, and all personnel evacuated the immediate area.

Last week, Oak Ridge Public Works Director Shira McWaters said it could cost an estimated $407,000 to repair the landslide, and the work should be complete by the end of July.

The water plant is on a ridge top above the main entrance to the Y-12 National Security Complex on Bear Creek Road. The landslide occurred next to the access road to the water plant on Saturday night, February 23. It’s the only access road to the water plant. It allows operations and maintenance workers to get to the water plant and deliver materials, equipment, and chemicals.

Filmmaker Keith McDaniel has completed a nine-year project to document the oral histories of about 400 current and former Oak Ridge residents, including those connected to the Manhattan Project during World War II.

The life stories were used to build a digital collection for the Oak Ridge Public Library’s Center for Oak Ridge Oral History, or COROH. McDaniel was part of the group that made plans for the COROH and, following the city’s receipt of an annual grant from the U.S. Department of Energy, took the contract for the documentary work.

“A lot of original Oak Ridgers were dying and getting older,” McDaniel said in a press release from Carson-Newman University. “We felt it was really important to collect their memories, to collect their stories.”

The one-on-one filmed interviews gave those connected to the Manhattan Project, and later to the city at large, the opportunity to share their life stories, the press release said.
