Abstract

This paper describes a method of calibrating the efficiency of an on-line detection device for fuel rod failure in a pressurized water reactor. 214Am, 137Cs, 60Co and 24Na were selected to produce 4 sets of liquid calibration sources, and a calibration system that could simulate the on-site measurement of the on-line detection device was established. Efficiency calibration was performed against γ-ray lines, which could be identified by a LaBr3(Ce) detector. After a true coincidence summing correction, an efficiency curve of the on-line detection device for fuel rod failure was obtained, with a calibration uncertainty of 3.5%.
