AbstractAbstract
[en] Horizontal burnup gradients were determined by gamma-ray spectrometry for the PWR spent nuclear fuel assemblies discharged from Kori Unit-1 and Unit-2 power reactors in 1985 and 1992, respectively. Gamma-ray Measurements of 4 faces of the fuel assembly were carried out using a under-water burnup measuring device in a pool of PIEF at KAERI. As a result of data analysis, horizontal burnup gradients of F02 assembly burned in Kori Unit-1 for 3 cycles were 11 % for the 1-3 faces and 7% for the 2-4 faces, and those of J44 assembly burned in Kori Unit-2 were 4 % and 19%. These values will be employed to determine the average burnup of fuel assembly with the axial burnup distribution determined by gross gamma scanning
