CRIS II Cerenkov Radiation Inspection System

The Cerenkov Radiation Inspection System II (CRIS II) is the newest generation CRIS device designed to view Cerenkov light produced by spent fuel assemblies stored in fuel ponds. It uses an image intensifier designed to amplify the ultra-violet (UV) portion of the Cerenkov light generated by spent nuclear fuel. This instrument is only sensitive to the 290-340 nm region of the spectrum, allowing it to be used under most normal lighting conditions found in a spent fuel pond.
