#ndt Idaho National Laboratory (INL) performs neutron radiography of highly-radioactive objects including used nuclear fuel. INL’s Neutron Radiography Reactor (NRAD) is a 250kW TRIGA reactor located beneath one of the world’s largest hot cells.
Prior to installing the ScanX Discover HR computed radiography (CR) system, INL used the foil-film transfer method. Highly-radioactive specimens are positioned for inspection using an elevator. Cassettes containing dysprosium and indium foils are placed behind the spec
