For members: Construction planned for SNS power upgrade

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.

Stop sign going in, stoplight coming out

The intersection of Tyler Road and Tennessee Avenue, which now includes a stoplight, is pictured above on Thursday, July 18, 2019.

A new stop sign will be installed and the traffic signal will be removed at the intersection of Tyler Road and Tennessee Avenue in the Jackson Square area in central Oak Ridge.

The new stop sign will be uncovered on Tuesday, July 23, at about 8 a.m., the City of Oak Ridge said in a press release Thursday.

“At present, both Tyler Road and Tennessee Avenue are controlled by a traffic signal,” the press release said. “The change is being made after a traffic study indicated the traffic pattern and crash history at this location does not justify the need for a traffic signal. The study also indicated that changing the right-of-way assignment to favor Tennessee Avenue will reduce delays.”

Four workers received small external doses, SNS outage started early after ‘pressure transient’

Note: This story was updated at 12 p.m. July 19.

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 when a furnace door blew open during an “unexpected violent reaction” in a chemistry laboratory at the Y-12 National Security Complex in May.

The door of the muffle furnace blew open while it was heating samples in an analytical chemistry laboratory in Building 9995 on Thursday, May 30, the Defense Nuclear Facilities Safety Board said.

The muffle furnace was damaged, the DNFSB said. It is used to heat samples to high temperatures. The glass vials containing the samples shattered, and some were expelled from the muffle furnace into the work area, the safety board said in a June 7 report.

No injuries reported in transformer fire at salt bath for depleted uranium

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.

The district attorney general in Anderson County has received a $240,000 federal grant to set up a family justice center.

The Anderson County Family Justice Center will help combat child abuse, domestic abuse, and elder abuse, Seventh Judicial District Attorney General Dave Clark said in press release on Tuesday. It will be organized and formed during the first year or two of the grant contract, Clark said.

“Upon opening the actual center, there will be a location where (Anderson County residents) with abuse issues can go to get services from a variety of providers who will all have a representative located in the Family Justice Center,” Clark said. “In addition, referrals may be made by the Family Justice Center to other organizations that can provide help.”

Melissa Miller has been hired as the site coordinator of the Family Justice Center.
