Verification of hardware for eddy current testing system

Nondestructive testing (NDT) for the construction and operating of NPPs plays an important role in confirming the integrity of the NPPs. Especially, Eddy current testing (ECT) is one of the primary nondestructive examination methods for in service inspection of the tubes in major components in NPPs. Korea Hydro and Nuclear Power Central Research Institute (KHNP CRI) has developed an eddy current testing (ECT) hardware (H/W) consisted of synthesizer, receiver, AD converter, FPGA (Field Programmable Gate Array) and processor unit. During the development of the ECT hardware, verification and validation of design is required in order to prevent errors and reduce cost. The printed circuit board (PCB) of ECT hardware was verified with simulation in order to configure prescribed performance. This paper gives an overview of the evaluating and applying FPGA based PCB in the ECT HW system
