KNOXVILLE—Although a turtle’s home may be on its back, some North American turtles face an uncertain future as a warming climate threatens to reduce their suitable habitat.

A new study conducted at the National Institute for Mathematical and Biological Synthesis at the University of Tennessee in Knoxville reconstructs the effects of past climate changes on 59 species of North American turtles and finds that the centers of the turtles’ ranges shifted an average of 45 miles for each degree of warming or cooling. While some species were able to find widespread suitable climate, other species, many of which today are endangered, were left with only minimal habitat.

Species in temperate forests and grasslands, deserts and lake systems, primarily in the central and eastern United States, were more affected by climate change than species along the Pacific Coast, in the mountain highlands of the western United States and Mexico, and in the tropics, according to the study, published in the journal PLOS ONE.

KNOXVILLE—The question of what to do with spent nuclear fuel in the U.S. has never been definitively answered. A University of Tennessee in Knoxville professor has received funding from the U.S. Department of Energy to develop new capabilities for evaluating potential alternatives to directly disposing of used fuel.

The award is part of the DOE’s 2013 Nuclear Energy University Programs which is awarding $42 million to 38 American universities and colleges for nuclear energy research and development projects focused on developing innovative solutions.

A proposal by Steven Skutnik, assistant professor in nuclear engineering, was awarded $755,000 to develop new capabilities for a fuel cycle simulator called CYCLUS by building on an Oak Ridge National Laboratory software package for nuclear fuel modeling called ORIGEN. [Read more…]

Lake City picked for PlanET demonstration project

Information from WYSH Radio

It has already been a banner week for Lake City.

On Monday, the Anderson County Commission’s Operations Committee voted to recommend purchasing the old Bank of America building in Lake City for $100,000 using part of the proceeds of the pending sale of county-owned land to the Hollingsworth Company for $303,000. The remaining $203,000 would be used as seed money for the start-up Anderson County Economic Development Fund. Supporters of the bank building purchase foresee using it as the new home of Coal Miners’ Museum as well as for storage and use as a satellite office for some county government entities.

Now, PlanET, a regional partnership of East Tennessee communities in Anderson, Blount, Knox, Loudon, and Union counties, has selected Lake City as one of its so-called Demonstration Project sites. The program will be funded through the Plan East Tennessee Grant and leverage in-kind services from the East Tennessee Community Design Center, or ETCDC, and the University of Tennessee School of Agriculture.

KNOXVILLE—President Barack Obama recently nominated University of Tennessee alumnus Kenneth L. Mossman to the Defense Nuclear Facilities Safety Board.

Now a professor of health physics at Arizona State University, Mossman is an expert in radiation health and safety. He received his master’s degree in 1970 and doctorate in 1973, both in radiation biology, from UT and is a member of the Dean’s Advisory Board for the College of Arts and Sciences. He established the Ken and Blair Mossman Professorship in Biomedicine, currently held by Associate Dean and Professor Cynthia Peterson.

The Defense Nuclear Facilities Safety Board is a five-member executive branch agency with safety oversight of all U.S. nuclear weapons facilities. Its mission is to identify potential threats to public health and safety at the U.S. Department of Energy’s defense nuclear facilities and to make safety recommendations to the secretary of energy and to the president. Among other things, the DNFSB issues weekly reports on Oak Ridge National Laboratory and Y-12 National Security Complex.

KNOXVILLE—Hypothetical scenario: A nuclear bomb is detonated in one of America’s most populated cities. Just as at a crime scene, the officials need to find the culprit.

Currently, the process of analyzing weapons debris to understand the performance or design of the device is painstakingly slow. But new research to be conducted at the University of Tennessee in Knoxville seeks to improve radiochemistry and nuclear forensics to enhance global security.

The new Radiochemistry Center of Excellence is being established through a $1.2 million grant from the National Nuclear Security Administration for the first year, with the potential for a total of $6 million for five years. The center will focus on research and education to advance UT and NNSA laboratories such as the nearby Y-12 National Security Complex, Los Alamos National Laboratory, and Lawrence Livermore National Laboratory. The center will begin operating immediately.
