Researchers from the University of Manchester, the U.K. National Nuclear Laboratory, and Clemson University have studied using crushed concrete at legacy nuclear facilities as a long-term sink for strontium-90, a radioactive contaminant found at many such sites. Their research has been published in the American Chemical Society journal ACS ES&T Water.

Researchers at the Department of Energy’s Argonne National Laboratory are investigating the details of plutonium chemistry with the goal of aiding the cleanup of the Hanford Site in Washington state. For more than 40 years, reactors located at Hanford produced plutonium for America’s defense program, resulting in millions of gallons of liquid radioactive and chemical waste.

The Nuclear Regulatory Commission announced on November 15 that it has awarded nearly $5.5 million in grants to support research and development activities in nuclear science, engineering, technology, and related disciplines under the University Nuclear Leadership Program (UNLP), previously known as the Integrated University Program.
