A number of recent studies have suggested that dry storage canisters (DSCs) made of austenitic stainless steel SS304 to store spent nuclear fuel located along coastal region may undergo stress corrosion cracking (SCC) if their useful life is extended due to lack of a permanent underground burial repository. It, therefore, becomes necessary to understand SCC behavior of SS304 in marine environment. We report here our results on SCC of SS304H in simulated sea-water using fracture mechanics approach as a function of temperature. The average crack growth rates were noted to be 0.975 × 10−10 ± 9.528 × 10−12, 3.258 × 10−10 ± 9.551 × 10−11, and 1.580 × 10−9 ± 2.593 × 10−10 m/s at 22, 37, and 60 °C, respectively. The activation energy of the crack growth process was estimated to be 60.9 kJ/mol corresponding to diffusion of hydrogen in steel. Optical microscopy revealed intergranular nature of the crack growth.

Special thanks are given to Dr. Scott Gordon from Colorado School of Mines for providing the SS304 plates, Chris Sanford for preparing the WOL specimens, Dr. Harvey West for the fatigue pre-crack experiments and the optical microscopes. We also appreciate the discussions with Prof. Zeev Shayer from Colorado School of Mines and Dr. Charles Bryan from Sandia National Laboratory about the experiment. This work was supported by NEUP IRP, “Innovative Approach to SCC Inspection and Evaluation of Canister in Dry Storage.”
