Underground tests dig into how heat affects salt-bed repository behavior

November 3, 2021 – 5:00 am

ALBUQUERQUE, N.M. — Scientists from Sandia, Los Alamos and Lawrence Berkeley national laboratories have just begun the third phase of a years-long experiment to understand how salt and very salty water behave near hot nuclear waste containers in a salt-bed repository. Salt’s unique physical properties can be used to provide safe disposal of radioactive waste, […]

An ‘apatite’ for radionuclides

October 20, 2015 – 9:20 am

ALBUQUERQUE, N.M. — Sandia National Laboratories geochemist Mark Rigali and his colleagues are developing and deploying apatite-based technologies to protect groundwater at sites contaminated by radionuclides and heavy metals. Apatite is currently being used at the U.S. Department of Energy’s Hanford Site in southeastern Washington State and the Fukushima Dai-ichi nuclear plant, “and, there are […]

Computer power clicks with geochemistry

January 28, 2014 – 5:00 am

ALBUQUERQUE, N.M. — Sandia National Laboratories is developing computer models that show how radioactive waste interacts with soil and sediments, shedding light on waste disposal and how to keep contamination away from drinking water. “Very little is known about the fundamental chemistry and whether contaminants will stay in soil or rock or be pulled off […]
