Abstract
Gamma-ray sensing probes operating under the Cerenkov effect measure the burnup of spent nuclear fuel assemblies. The probes include an optical fiber that reacts to gamma rays coming from the spent nuclear fuel assembly and emit light via the Cerenkov effect. A scatterer surrounds the optical fiber to increase the light emitting efficiency of the optical fiber by the Compton electron scattering. A collimator composed of shielding material surrounds the scatterer. The collimator has a slit groove which is open in one direction for directing the gamma rays from the spent fuel assembly to the scatterer.
