Abstract
The invention concerns a method and a device for evaluating the integrity of the nuclear fuel in a nuclear plant having a reactor ( ) enclosing a reactor core formed by a number of fuel cladding members ( ) arranged to enclose said nuclear fuel. The value of each of a number of parameters including activity data ( ) of the off-gases from the reactor is determined. The value of each of a number of second parameters including chemical data and activity data of the liquid ( ) flowing through the reactor is determined. The value of each of a number of operational parameters ( ) including at least one of the reactor effects, control rod position, actual fuel type, flow of off-gases, and flow of the liquid flowing through the reactor is determined. The value of the first and second parameters are standardized ( ) in relation to the values of said operational parameters. The standardized values and the values of the operational parameters are analysed ( ) and the integrity of the fuel is estimated based on the analysis. The invention also comprises producing guidelines for the continuing operation of the plant with regard to said estimation.
