KNOXVILLE—An international research team led by an assistant professor at the University of Tennessee in Knoxville has received a grant to help with work involving a key component of nuclear reactors.

The U.S. Department of Energy grant is worth $800,000 over three years, and it has been awarded to UT Assistant Professor Haixuan Xu. It’s part of the Nuclear Energy University Programs funding and will be used to work on a pair of particular steel alloys, a press release said.

“Getting support on this will allow us to investigate and understand the defect evolution in these materials,” said Xu, of the UT Department of Materials Science and Engineering. “What we hope to gain is fundamental insight into the effects of radiation on the alloys so that we can better predict and detect how they will break down over time and adjust the materials accordingly.”

The alloys in question would be used in sodium-cooled reactors. Xu’s research is important because little is known about how the materials stand up to high levels of radiation over time. [Read more…]

Habitat Volunteers on Lake City Roof

Two families and the Holiday Bureau have new roofs this month, thanks to volunteers from two different colleges and local men that routinely volunteer for Habitat for Humanity of Anderson County, a press release said.

The first week of March, a group of students from the Milwaukee School of Engineering came to Oak Ridge as part of Habitat for Humanity’s Collegiate Challenge program. The students were housed at First Baptist Church of Oak Ridge. First Baptist shared their facilities for four weeks in a row with four different groups.

The Holiday Bureau has a bicycle storage shed, measuring 16 feet x 78 feet, that had a very old and leaky roof. Now, the shed has a new roof, and it only took the students four days, the press release said. Tim Marcum, HFHAC’s chief operating officer, coordinated this project in an effort to help another nonprofit. [Read more…]
