The maximum fuel rod temperature within a spent-fuel dry storage canister of Wolsong nuclear power plant unit 1 [a Canada deuterium uranium (CANDU) pressurized heavy-water reactor], which should not exceed the potential fuel oxidation temperature (180[degrees]C) for thermal safety, cannot easily be obtained by any single existing method because of the complicated geometric shape of the 37-element CANDU spent-fuel bundles within a storage basket. However, the mean temperature distribution of the fuel bundles within a basket can be calculated. The main objective of this paper is to present an analytical method to evaluate the maximum fuel rod temperature of a 37-element CANDU spent-fuel bundle when its outermost fuel rod temperature is known a priori or when it can be calculated.
