Effects of Irradiation Damage on Electro-Magnetic Properties of Reactor Pressure Vessel Steels

The study on the variation of electrical properties and magnetic properties of reactor pressure vessel steels during its irradiation embrittlement procedure were introduced, and the current research achievements and shortcomings were discussed. Finally, it is pointed out that exploration of the potential relevance between the mechanical properties, electrical properties and magnetic properties of in-service reactor pressure vessel can result in the nondestructive evaluation techniques, which provides a new way of irradiation surveillance for reactor pressure vessels, as an important supplement to the existing conventional destructive tests program.
