Relatively short-term (approximately 2000 h) tests were conducted on precracked self-loaded fracture mechanics specimens of two candidate container materials in simulated Hanford groundwater at two temperatures: 150/sup 0/C and 250/sup 0/C. The two materials tested were cast ASTM A27 Grade 60-30 steel, and weldments in wrought ASTM A36 steel. Three different levels of applied stress intensity factors (K) were tested for each material/temperature combination. The results of these short-term tests suggested no crack extension in either material. In addition, short-term (1 week) load relaxation tests were conducted on precracked steels at 250/sup 0/C. These results aid in the interpretation of test results for specimens tested for larger exposures in groundwater environments.
