In connection with boiling-water reactor (BWR) applications, it has been demonstrated that both weld sensitized and furnace sensitized Type 304 stainless steel exhibit stress-corrosion cracking (SCC) in oxygenated high-temperature water(1-14). In general, furnace sensitized material cracks more readily than weld sensitized material and cracking occurs more readily as stress level increases, oxygen level increases, and temperature increases. Long term low-temperature sensitization such as might occur at BWR operating conditions (288 C) also appears to increase SCC susceptibility(10). The entire problem is under continuing investigation and it is expected that even better delineation of the factors that affect SCC of sensitized Type 304 stainless steel in BWR environments will be forthcoming in the next several years.
