The word “exotic” may not spark thoughts of uranium, but Tyler Spano’s investigations of exotic phases of uranium are bringing new knowledge to the nuclear nonproliferation industry. Spano, a nuclear security scientist at the Department of Energy's Oak Ridge National Laboratory, and her colleagues examined four previously understudied phases of uranium oxide: beta (β-), delta (δ-), epsilon UO3 (ε-UO3) and beta U3O8 (β-U3O8).
Brad Roberts has received one of the highest honors bestowed by the Government of Japan. The director of the Center for Global Security Research (CGSR) at Lawrence Livermore National Laboratory (LLNL), Roberts has been given the Order of the Rising Sun.
For the first time, researchers produce more energy from fusion than was used to drive it, promising further discovery in clean power and nuclear weapons stewardship.
Although the likelihood of a terrorist nuclear attack is extremely low, a lot of work is required to prepare for such an unthinkable event. That’s why a response team assembled by the National Nuclear Security Administration (NNSA) recently trained in eastern Idaho’s desert on ways to collect and analyze simulated debris from a nuclear detonation. Nuclear forensics—the science of determining the origin of nuclear material—is an essential element of the United States’ strategy to prevent nuclear terrorism.
Recycling used nuclear fuel makes the most of nuclear power’s carbon-free energy potential. Argonne has received major funding to develop technologies that may result in a sustainable fuel stock and a reduction in U.S. dependency on fossil fuels.
The marketplace debut of Idaho National Laboratory’s Colorimetric Detection of Actinides, or CoDeAc, isn’t the finish to the award-winning technology’s story. According to its inventors and now investors, it’s just the beginning of a new chapter. “CoDeAc has a bright future,” INL Researcher and CoDeAc inventor Catherine Riddle said. “As it gains interest and expands, there will be new opportunities for future colorimetric detection products and a diverse range of new technologies geared towards rapid radionuclide detection.”
KIMM has developed a simulator that enables operators to simulate underwater laser and plasma cutting and to operate equipment in a condition, similar to the actual dismantling environment by virtualizing the remote nuclear dismantling system.
More than 140 U.S. college teams competed to test their cyber defense skills and protect a fictional electric vehicle manufacturer’s solar installation from simulated cyberattacks.
PNNL researchers use machine learning and data analytics to assist with detection of nuclear proliferation and nuclear material trafficking.
Students from the Little Village Lawndale High School Campus saw how Argonne scientists — many of Hispanic/Latino heritage — perform pivotal research during the 17th annual Hispanic/Latino Education Outreach Day.

Nuclear energy is an exciting carbon-free energy source. Recent work at Argonne National Laboratory shows how nuclear energy can improve and why it is such an enticing resource in the fight against climate change.
To simulate stellar novae accurately on computers, researchers need accurate inputs for nuclear reaction rates. Nuclear physicists have now determined an important and challenging proton-capture reaction rate using laboratory experiments. A state-of-the-art nova simulation incorporates the new experimental information, allowing physicists to compare the results for comparison to actual nova observations.
