Nondestructive inspection using Rotating Field Eddy Current (RoFEC) Probes

The use of Rotating Field Eddy Current (RoFEC) Probe for inspection of metallic steam generator tubes in nuclear power plant offers higher operation speed and sensitivity relative to traditional rotating probe coil and array probes. This paper investigates the feasibility of the RoFEC probe which does not require rotating the coils mechanically. Results of finite element modeling and simulation results with Reduced Magnetic Vector Potential Formulation (RMVP) are presented for non-magnetic and ferromagnetic tube inspection.
