This paper presents the flaw assessment programme undertaken in France for PWR steam generator tubes affected by stress corrosion cracking. Failure criteria were deduced from burst tests on various crack configurations. Stresses and critical crack sizes were estimated for all operating conditions. The corresponding leak rates during normal operation were computed after validation of the model. Then it was shown that a significant primary-to-secondary leak should precede tube failure. © 1986.
