In order to obtain knowledge of the corrosion behavior of carbon steel in the operating environment of TEPCO’s Fukushima Daiichi Nuclear Power Plant （1F）, water quality change behavior was analyzed using water quality data published by TEPCO. Based on the results of the analysis, a full-scale corrosion test of carbon steel pipes was conducted in an environment simulating that of 1F’s spent fuel pool cooling system. Based on the test results and previous studies, a uniform corrosion growth prediction model was proposed applicable to static and flowing water conditions in steel pipes from seawater to freshwater （including diluted seawater）.
This paper presents an overview of the research carried out on the evaluation of the corrosion behavior of carbon steel in seawater and freshwater environments.
