Abstract
The eddy current testing cable is used for inspection of thickness of evaporator tube in Monjyu (fast breeder reactor). This paper deal with the vibration noise of ECT cable generating when this cable is inserted or pulled back in the evaporator tube. We experimented with mock-up and examined characteristic of vibration noise of ECT cable. This experiment showed the vibration noise in inserting ECT cable was bigger than that in pulling back it and the frequencies of vibration were converged on one. We confirmed the countermeasure for ECT cable could control the vibration noise in radial direction of evaporator tube.
