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.
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.
A better way of welding targets for Oak Ridge National Laboratory’s plutonium-238 production has sped up the process and improved consistency and efficiency. This advancement will ultimately benefit the lab’s goal to make enough Pu-238 – the isotope that powers NASA’s deep space missions – to yield 1.5 kilograms of plutonium oxide annually by 2026.
Porter Bailey started and will end his 33-year career at ORNL in the same building: 7920 of the Radiochemical Engineering Development Center.
East Tennessee occupies a special place in nuclear history. In 1943, the world’s first continuously operating reactor began operating on land that would become ORNL.
When Sandra Davern looks to the future, she sees individualized isotopes sent into the body with a specific target: cancer cells.
