Experimental data of radioactivity deposition rates on stainless steel specimens exposed to high-temperature water including hydrogen peroxide (H2O2) and oxygen (O2) were applied to the evaluation of Co-60 accumulation rates in oxide films on the stainless steel piping of a boiling water reactor (BWR) primary cooling system and then an empirical formula of Co-60 deposition rate coefficient was proposed as a function of exposure time. The empirical formula was applied to the evaluation of the amount of Co-60 deposition on the stainless steel piping of BWR primary cooling systems under normal water chemistry (NWC) and hydrogen water chemistry (HWC) conditions. The results are summarized as follows.1) The Co-60 deposition rate coefficient was almost independent of O2 concentration ([O2]), while it decreased as H2O2 concentration ([H2O2]) decreased.2) The proposed empirical formula determined on the basis of experiments under H2O2 conditions could give a much better estimation of the Co-60 deposition rate coefficient on stainless steel under NWC conditions of BWR than the previous formula based on the data under simple O2 conditions.3) The deposition amounts of Co-60 on stainless steel piping under HWC conditions were evaluated using the formula, which suggested that those without any prefilming treatment were several times as high as those under NWC conditions.4) The increase in Co-60 deposition under HWC conditions was caused by the less protective film in mitigating Co-60 deposition and it could be avoided by several hundred hours of operation under NWC conditions prior to HWC operation. The effect on material integrity is evaluated to be negligible.
