This talk covers the results from a 4-year program of evaluating the effect of very low levels of chloride (< 5ppb) on the stress corrosion cracking (SCC) behavior of low-alloy pressure vessel steel (A533B) in high temperature water. Three different heats of low alloy steel from reactor vessels were evaluated under both periodical partial unloading condition and constant load/K condition. Effects of chloride (1-5 ppb) stress intensity factor (K) specimen orientation and hydrogen chemistry were studied in detail. It was found that the compositional percentage of sulfur is a weak measure of SCC susceptibility under ppb level of chloride. The potential reason that may cause heat-to-heat difference on SCC suscetibility will also be discussed. The result from this program suggests that the chloride level as low as 2-4 ppb can increase the SCC susceptibility of low alloy steel in BWR environment.

Case study: Cracking occurred in a (UNS S32100) type austenitic stainless steel nozzle fitting at a low point in the reactor effluent piping in a Gasoil Hydrotreater unit following start up. Normal preventive measures had been taken.  The failed sample was removed for metallurgical analysis and determination of mechanism(s).
