Constant load stress corrosion tests were conducted on type 304 SS, which had been irradiated to fast neutron fluences in the range from 0. 12 to 3. 00 x 10(21) n/cm2 (E > 1 Me V) in two boiling water reactors. The material originated from three different heats and product forms. Since some of the test specimens had fractured in a creviced region outside of the gauge section, times to failure and % intergranular stress corrosion cracking were evaluated in terms of specimen type, crevice vs noncrevice failures, stress level, and fluence. Irradiation-assisted stress corrosion cracking failures were obtained at fluences as low as 0.38 x 10(21) n/cm2 and at stresses well below the yield strength.
