Nuclear physicist Caroline Nesaraja of the Department of Energy’s Oak Ridge National Laboratory evaluates nuclear data vital to applied and basic sciences. 

Technicians John Dyer and T. Dyer use a manipulator arm in a shielded cave in ORNL’s Radiochemical Engineering Development Center to separate concentrated Pm-147 from byproducts generated through the production of Pu-238.

A new method developed at Oak Ridge National Laboratory proves one effort’s trash is another’s valuable isotope. One of the byproducts of the lab’s national plutonium-238 production program is promethium-147, a rare isotope used in nuclear batteries and to measure the thickness of materials.

A team of researchers at Oak Ridge National Laboratory and Purdue University has taken an important step toward this goal by harnessing the frequency, or color, of light. Such capabilities could contribute to more practical and large-scale quantum networks exponentially more powerful and secure than the classical networks we have today.

Twenty-seven ORNL researchers Zoomed into 11 middle schools across Tennessee during the annual Engineers Week in February. East Tennessee schools throughout Oak Ridge and Roane, Sevier, Blount and Loudon counties participated, with three West Tennessee schools joining in.

The Perseverance rover

On Feb. 18, the world will be watching as NASA’s Perseverance rover makes its final descent into Jezero Crater on the surface of Mars. Mars 2020 is the first NASA mission that uses plutonium-238 produced at the Department of Energy’s Oak Ridge National Laboratory.
