Noble metal chemical addition (NMCA) technology has been widely adopted for BWR plants in the US as a means to mitigate stress corrosion cracking (SCC). Dose rate of the reactor water recirculation system piping of some BWR plants that apply a combination of NMCA and zinc injection technology have gradually decreased. Chemical decontamination removes 60Co, but also the noble metal from the piping surfaces. Thus, effect of dose rate reduction by NMCA is decreased in the plant operating period after che...
