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.

Wisconsin-based fusion technology company SHINE Technologies announced today the signing of a memorandum of understanding with Zeno Power to develop a nuclear materials supply chain for its commercially available radioisotope power systems (RPSs). Under the MOU, SHINE plans to provide Zeno with strontium-90 to power its RPSs, which are capable of providing continuous power in harsh environments.
