Oak Ridge is home to more higher-risk excess contaminated facilities than any other U.S. Department of Energy site in the nation, but recent demolition projects are helping change that. This month, the Oak Ridge Office of Environmental Management, or OREM, eliminated two buildings from the higher-risk list.

The projects were part of DOE’s Excess Contaminated Facilities Initiative, an effort to stabilize facilities, reduce risks, and in some cases accelerate demolition schedules. Oak Ridge is of particular interest since the site houses 297 “excess” facilities—facilities that are no longer operational or serving DOE’s missions. As of December 2016, Oak Ridge contained 60 of DOE’s inventory of 203 higher-risk excess facilities.

“These projects are highlighting EM’s value as crews are removing risks and clearing land for DOE’s important ongoing missions,” said OREM Federal Project Director Brian Henry. “Tearing down these high-risk facilities is a first step with many more planned in the years ahead.” [Read more…]

Cedar Springs Homeschool advances to National Science Bowl 

Countless hours studying math and science paid off for some exceptionally bright students from Cedar Springs Homeschool. They were first-place winners in the U.S. Department of Energy’s annual Tennessee Science Bowl this past weekend.

Cedar Springs Homeschool competed against 58 other high school teams on Saturday, February 27, to place first in the annual competition. The schools edged out its competition by successfully answering challenging questions in mathematics, physics, chemistry, biology, earth and space science, and energy.

Held at Pellissippi State Community College’s Blount County Campus, the Tennessee Science Bowl is the nation’s third largest regional competition. The regional bowl prepares students to compete nationally with other exceptional students from schools across the country. As the first-place team, Cedar Springs Homeschool receives an all-expenses-paid trip to the DOE National Science Bowl in Washington, D.C., April 28-May 2, as well as a $1,000 cash prize and a first-place trophy.

​NASA’s New Horizons spacecraft just accomplished one of the most exciting feats in the history of space exploration. After a 9.5-year, 3-billion-mile journey, the mission’s historic flyby of Pluto has provided us with our first-ever closeup views of the frozen world at the edge of the solar system. It’s a remarkable achievement, one that wouldn’t have been possible without careful planning, ingenuity—and a little help from the U.S. Department of Energy.

In 2006, when NASA engineers were designing New Horizons, they knew that it would need a long-lasting, compact and incredibly reliable power source to survive the cold, dark reaches of outer space.

Solar power was out of the question. The spacecraft’s itinerary would take it billions of miles from the center of the solar system into the realm of Pluto and the Kuiper Belt. That far out, the Sun shines with just a tiny fraction of the intensity we see here on Earth—scarcely brighter than the stars in the night sky. Other options like batteries or fuel cells wouldn’t last long enough. [Read more…]

WASHINGTON—Building on President Obama’s newly announced plan to cut carbon pollution, the Energy Department this week announced four research and development projects to bring next-generation biofuels on-line faster and drive down the cost of producing gasoline, diesel, and jet fuels from biomass. The projects—located in Oklahoma, Tennessee, Utah, and Wisconsin—represent a $13 million Energy Department investment.

One of the projects selected for negotiation is worth up to $2.1 million and located at Oak Ridge National Laboratory. [Read more…]
