Magnetic Property Changes in various Structural Steels Due to Irradiation

Nondestructive evaluation in nuclear power plants has been a growing concern for electric utility operators over the past decade 1. Many plants are operating beyond their original design lives primarily through intermittent replacement of individual components as necessary. It is critically important for the NDE field to develop technology that can evaluate the life expectancy of components in these plants, such as steam boiler pipes, headers and tubes, steam turbine rotors and blades, and nuclear pressure vessels. These components typically experience long service exposure, high temperature under high loading conditions, corrosive media and neutron irradiation. The focus of this paper will be on the irradiation effects
