Description

A method of LWR fuel element (FE) cladding damage calculation which allows us to reduce safety factor five times, when estimating cladding durability according to the strength criteria, has been described. A criterion model of FE properties control efficiency and a probabilistic model of FE operating calculated parameters, have been developed. A method of VVER-1000 fuel rearrangement control which allows us to find rearrangement algorithms having minimum values of maximum and average cladding damage, as well as maximum uniformity of damage and burnup among all the FAs for a rearrangement algorithm, has been proposed
