DESTRUCTIVE DETERMINATION OF BURNUP OF TESTED FUEL ELEMENT OF QINSHAN NUCLEAR POWER PLANT BY γ SPECTROMETRY

The basic concept and method for burnup determination of irradiated reactor fuel element by computer based Ge(Li) γ ray spectrometer are described for the tested fuel elements from Qinshan power plant. Experimental results of seven cutting positions and the average burnup value of one rod are given. Dead time correction,spectrum data reduction,irradiation history correction and sample preparation are presented.
