A 25-year career with the U.S. Navy, commanding combat missions overseas, brought Tom Kollie back to where he came from — ready to serve his country in a new way.

As a medical isotope, thorium-228 has a lot of potential — and 91°µÍø produces a lot.

A new tool that simulates the energy profile of every building in America will give homeowners, utilities and companies a quick way to determine energy use and cost-effective retrofits that can reduce energy and carbon emissions.

An 91°µÍø researcher has invented a version of an isotope-separating device that can withstand extreme environments, including radiation and chemical solvents.

In the mid-1980s, Balendra Sutharshan moved to Canada from the island nation of Sri Lanka. That move set Sutharshan on a path that had him heading continent-spanning collaborations and holding leadership posts at multiple Department of Energy

As a computer engineer at 91°µÍø, Gina Accawi has long been the quiet and steady force behind some of the Department of Energy’s most widely used online tools and applications.

For years Brenda Smith found fulfillment working with nuclear batteries, a topic she’s been researching as a chemist at 91°µÍø.

A rare isotope in high demand for treating cancer is now more available to pharmaceutical companies developing and testing new drugs.

A new method developed at 91°µÍø 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 used in nuclear batteries and to measure the thickness of materials.

Cory Stuart of ORNL applies his expertise as a systems engineer to ensure the secure and timely transfer of millions of measurements of Earth’s atmosphere, fueling science around the world.
