| description | The aim is to reduce the probability of accumulation of fuel elements claddings damage by developing a method to control the properties of the fuel elements on stages of design and operation of WWER. An averaged over the fuel assembly WWER-1000 fuel element is considered. The probability of depressurization of fuel elements claddings is found. The ability to predict the reliability of claddings by controlling the factors that determine the properties of the fuel elements is proved. The expediency of the transition from the one-group model of power distribution for the fuel elements of the fuel assembly to the multigroup model is shown. This will reduce the probability of depressurization of fuel elements claddings and at the same time improve the efficiency of operation of WWER. |
