Determination of Cerenkov light absorption by fuel pond water using a calibration light source
2011 (English)Conference paper (Other academic)
Quantitative measurement of Cerenkov light generated by spent fuel assemblies requires anunderstanding of the absorbance characteristics of the spent fuel pond water. The presence ofparticulate or organic material can severely attenuate the transmission of the ultravioletcomponent of the Cerenkov spectrum. This can make the quantitative measurement of theCerenkov light using a digital Cerenkov viewing device difficult or in some cases impossible.A calibration light source that can be inserted into the fuel pond has been constructed. Thissource generates a known ultraviolet light flux. Measurements of this source can be used tocalculate the absorbance of Cerenkov light by the fuel pond water and in turn compensate for theabsorbance when measuring the intensity of a spent fuel assembly. This paper discusses thechallenges of constructing such a device and the results from measurements in two spent fuelponds.
