Description

A method is presented for the determination of the number of defective fuel pins in PWRs. The method uses measured values of reactor coolant activity of two fission-product isotopes (e.g. 131I and 133I) and evaluates the possible number of failures of two different sizes of break. Encouraging results have been obtained for two different reactors which experience a significant amount of failed fuel verified by sipping. The present method can be extended for application to BWRs.
