Outline of Final Research Achievements

Correlation between electrical properties and various physical/chemical states in the nuclear fuel were investigated by using surrogate materials. Electrochemical impedance measurement with focus on interaction between fuel matrix and metal phases has implied possible electrical interaction in spite of independancy of each phases in terms of structures.
