TEMA realigns boundaries to improve response

The Tennessee Emergency Management Agency will issue revised emergency sectors for the U.S. Department of Energy’s Oak Ridge Reservation on Wednesday. These sectors, labeled A-Y, determine which areas should take action if an event occurs at one of DOE’s sites locally. The new sector boundaries have improved correlation with roads, waterways, and recognizable landmarks.

“Knowing their emergency sectors will help residents better understand what to do when directed to take action by state or local emergency officials. Instructions pertaining to their safety will be issued by sector,” said Jim Bassham, TEMA director. “Periodic updates to emergency plans, like these changes, are part of TEMA’s normal review process.”

DOE and TEMA have been partners in a public information campaign aimed at the more than 50,000 people that live or work within a five-mile radius of Oak Ridge’s three main sites: the Y-12 National Security Complex, Oak Ridge National Laboratory, and East Tennessee Technology Park. An updated version of a joint publication, “What to do if an emergency occurs on the Oak Ridge Reservation,” will be available on March 12. The booklet will be on DOE’s website for area residents to read and reference at http://science.energy.gov/isc/emergency-information/. [Read more…]

ORHS team will compete in National Science Bowl

High school students from across Tennessee competed on Saturday, Feb. 22, at Pellissippi State Community College’s Blount County Campus, in the U.S. Department of Energy’s Tennessee Science Bowl competition. Fifty-five high school teams comprised of four students, and one alternate student, answered challenging mathematical problems and tested their knowledge in broad disciplines including chemistry, biology, earth and space science, physics, and energy.

Training for months after school, the student competitors committed hours of study to expanding and honing their mathematics and science knowledge and competition skills. And, all their work showed. Many of the competition rounds came down to the last nail-biting seconds before a winner emerged. However, in the end, Oak Ridge High’s Team 1 edged out their competitors, placing first.

Oak Ridge High School received a $1,000 cash prize, a first-place trophy, and an all-expenses-paid trip to the DOE National Science Bowl in Washington, D.C., from April 24-28, when they will compete against other winning teams from around the nation. [Read more…]

Using a new microscopy method, researchers at Oak Ridge National Laboratory can image and measure electrochemical processes in batteries in real time and at nanoscale resolution.

Scientists at ORNL used a miniature electrochemical liquid cell that is placed in a transmission electron microscope to study an enigmatic phenomenon in lithium-ion batteries called the solid electrolyte interphase, or SEI, as described in a study published in Chemical Communications.

The SEI is a nanometer-scale film that forms on a battery’s negative electrode due to electrolyte decomposition. Scientists agree that the SEI’s formation and stability play key roles in controlling battery functionality. But after three decades of research in the battery field, details of the SEI’s dynamics, structure, and chemistry during electrochemical cycling are still debated, stemming from inherent difficulties in studying battery electrode materials in their native liquid environment.

“We’ve used this novel in situ method to understand the dynamics of how this layer forms and evolves during battery operation,” said Raymond Unocic, ORNL research and development staff scientist. [Read more…]

Note: Anderson County Emergency Management Director Steve Payne recently responded to a citizens’ question about safety measures the county has in place to protect drinking water in the event of a hazardous situation like that which recently occurred in West Virginia. Here’s Payne’s response, which was forwarded by the County Mayor’s Office, which had initially received the question.

Dear Mayor Frank,

Please forward to the citizen who asked:

What safety measures does Anderson County have in place to protect citizens’ drinking water in the event of a hazardous situation like that which occurred recently in West Virginia?

Anderson County is home to some 50 facilities that manufacture, process, store, or utilize quantities of hazardous radiological or chemical materials. The majority of these facilities are located in industrial parks in the county and cities of Oak Ridge, Clinton, and Lake City.

Facilities with quantities of hazardous materials that meet or exceed threshold levels established by the U.S. Occupational Safety and Health Administration (OSHA) are required by federal law to file each year a Tier 2 Report stating the material(s) and quantity on site. In addition to the name and quantity of each material, the report includes Material Safety Data Sheet (MSDS), a site map showing location of material, type of storage container, type of storage conditions, and description of dikes, holding basins, and other safeguard measures. Tier 2 reports received in 2013 from private, non-DOE facilities identify 42 separate hazardous materials. [Read more…]
