Sandia to put nuclear waste storage canisters to the test
December 9, 2020 • ALBUQUERQUE, N.M. — Sandia National Laboratories is outfitting three 22.5-ton, 16.5-feet-long stainless-steel storage canisters with heaters and instrumentation to simulate nuclear waste so researchers can study their durability. The three canisters, which arrived in mid-November and have never contained any nuclear materials, will be used to study how much salt...

How to multitask when nuclear nonproliferation is on the line
September 29, 2020 • ALBUQUERQUE, N.M. — New cognitive science research from Sandia National Laboratories shows that while maps can help someone identify landmarks while being escorted, using one also limits situational awareness and knowledge of surroundings not highlighted on the map. This finding is one of several coming from a three-year project that...

Containing a nuclear accident with ground-up minerals
September 30, 2019 • ALBUQUERQUE, N.M. — Researchers at Sandia National Laboratories are developing a promising new way to prevent the spread of radioactive contamination and contain the hot molten mass that develops within a nuclear reactor during a catastrophic accident. During a three-year Laboratory Directed Research and Development project, a team of scientists...
