| description | There is provided a pit initiation evaluation system or the like capable of predicting pit initiation effectively and at low cost. In a pit initiation evaluation system of an embodiment, a pit initiation evaluation unit creates and retains, based on a dry-wet alternate time data, a deposit impurity concentration data, and a pit initiation data on pitting corrosion initiated in each of a plurality of turbine stages when an operation is actually performed in the steam turbine, a pit initiation evaluation table presenting a relationship between a dry-wet alternate time, a deposit impurity concentration, and pit initiation. Further, the pit initiation evaluation unit is configured to evaluate, by using the pit initiation evaluation table, pitting corrosion to be initiated in each of the plurality of turbine stages in an operation planned for the steam turbine. |
