ORNL neutrons add advanced polarization capability for measuring magnetic materials

Neutron scattering instruments at ORNL’s HFIR and SNS are undergoing upgrades which will enable them to study magnetic phenomena previously not possible in the US. Incorporating a device for spherical neutron polarimetry enables the ability to characterize complex magnetic systems in new dimensions for materials that could be developed for enhanced data storage and quantum computing technologies.

Containing a nuclear accident with ground-up minerals

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 discovered and patented a process for injecting sand-like minerals into the core of a nuclear reactor during an accident to contain and slow down the progression of a meltdown.
