In 2011, a devastating earthquake and tsunami led to a core meltdown at Japan's Fukushima Daiichi Nuclear Power Plant, resulting in fuel debris containing mixtures of nuclear fuel and other materials.
The scattering method, highly sensitive to high-atomic-number elements like uranium, has been demonstrated as a promising tool for evaluating nuclear materials in fuel debris.
Muon scattering tomography creates images by measuring how muons deflect as they penetrate materials.
After developing a prototype muon scanner, researchers used muon scattering to evaluate nuclear materials in fuel debris, which is crucial for safe handling and storage.
Author's summary: Muon scattering helps evaluate nuclear fuel debris.
