Description

In order to investigate the behaviour of PWR fuel rods, eight fuel rods extracted from reactor of Qinshan NPP(QNPP) were examined at the hot cell facility ofChina Institute of Atomic Energy (CIAE) in Beijing. The maximum burnup was about 40 GWD/TU. This paper presents the results of non-destructive examination. The results included: 1) Status of cladding surface, 2) cladding integrity, 3) distribution of oxide film on the outer surface of claddings, 4) dimensional change on axial and circumferential, 5) distribution of fission products in the fuel column, 6) defects, uniformity and structural integrity of the fuel and cladding. The obtained data could be used to evaluate the security, reliability and nuclear fuel performance, and for PWR fuel improvement.
