A method for VVER fuel element cladding reliability prediction
Abstract
Considering a VVER-1000 fuel assembly averaged fuel element (FE), based on the accepted FE cladding damage limit value, the FE cladding failure probability was determined, thus the possibility of this reliability pre-diction by means of controlling the factors determining the FE properties has been proved. The appropriateness of innovation development of the automated program-technical complex controlling the FE properties at VVER design and op-eration stages, lowering the FE cladding failure probability and, at the same time, increasing the VVER operation economic efficiency, has been proved.
