Abstract

A large amount of seawater and freshwater were injected into the nuclear reactors and spent fuel pools as emergency measures in response to the Fukushima Daiichi Nuclear Power Station accident that occurred on March 11, 2011. In response to this situation, the “Fukushima Daiichi Nuclear Power Station Corrosion Countermeasures Study Group” was established with members from academia, plant manufacturers, water treatment industry, and research institutes. The committee examined the countermeasures for potential corrosion problems in spent fuel pools, where the situation was known somewhat clearly. In the committee, major components and structures directly related to the safety function of the fuel pool were selected, and corrosion modes to be considered, possibility of occurrence, and countermeasures were discussed for each component. This paper describes the concept of the study and the outline of the results.
