Keywords:Boiling water reactor, crevice corrosion , stainless steel, high temperature water

Effect of geometry on corrosion environment of stainless steel in high temperature water have been studied. Stainless steels with crevice were immersed into 561K water. Surface oxide layer and electrical conductivity of crevice solution have been analyzed to identify crevice environment.
