Description: Around the world, spent nuclear reactor fuel is being moved from underwater pools to dry casks for long-term storage. However, the lethal radiation fields inside these casks, along with their massive size (100 + tons, 12-inch steel walls) makes regular, open inspections both difficult and expensive. This video introduces the system, called Compton-Dry Cask Imaging Scanner, which is used at Idaho National Laboratory to verify and document the presence of spent nuclear fuel rods in dry storage casks when a security seal is lost or tampered; and determine their isotopic composition without moving or opening the cask. Using a precise positioning device, gamma-ray collimator, and a high-purity germanium detector, the imager mounts to the top of the cask and can analyze its contents in 24 hours. The imager positions the collimated gamma-ray detector directly above each spent fuel slot in the cask, and records a gamma-ray energy spectrum.
