ORNL’s Steven Arndt to serve as American Nuclear Society president

Steven Arndt, distinguished R&D staff member in the Nuclear Energy and Fuel Cycle Division at Oak Ridge National Laboratory, began a one-year term on June 16 as the 68th President of the American Nuclear Society.

ANS is the largest organization dedicated to the study of nuclear sciences in the world, with more than 10,000 members throughout 50 plus countries. The society unites those studying nuclear sciences and technologies from the vantage point of improving people’s lives and preserving the planet.

Physicists confront the neutron lifetime puzzle

To solve a long-standing puzzle about how long a neutron can “live” outside an atomic nucleus, physicists entertained a wild but testable theory positing the existence of a right-handed version of our left-handed universe. They designed a mind-bending experiment at the Department of Energy’s Oak Ridge National Laboratory to try to detect a particle that has been speculated but not spotted.

Closed-loop additive manufacturing fueled by upcycled plastic

Researchers at the Department of Energy’s Oak Ridge National Laboratory have developed an upcycling approach that adds value to discarded plastics for reuse in additive manufacturing, or 3D printing. The readily adoptable, scalable method introduces a closed-loop strategy that could globally reduce plastic waste and cut carbon emissions tied to plastic production.

Kothe named associate laboratory director for Computing and Computational Sciences

Doug Kothe has been named associate laboratory director for the Computing and Computational Sciences Directorate at the Department of Energy’s Oak Ridge National Laboratory, effective June 6.

Jeff Nichols, the current associate laboratory director for computing and computational sciences, is set to retire on July 1 after 13 years in the position.

Researchers aim to better quantify greenhouse gas emissions from hydropower reservoirs

As the United States moves toward more sustainable and renewable sources of energy, hydropower is expected to play a pivotal role in integrating more intermittent renewables like wind and solar to the electricity grid because hydropower can fill gaps in generation when these forms of energy are unavailable.
