Abstract
The reasons for unsealing of VVER and RBMK fuel elements are discussed on the basis of the results of post-reactor investigations. The fuel elements in both types of reactors become unsealed because of their interaction with foreign objects present in the coolant flow. The mechanisms of the degradation of some properties of the unsealed fuel elements during further operation are determined.
