| Abstract: | The structure noise detecting technique for the control rod driving mechanism (CRDM) has been researched for CRDM of screw and roller driven. The sensitive characteristics and failure criteria in the rise and fall of CRDM have been obtained by the time and frequency analysis of the structure noise signals of CRDM. The test results indicated that the time and frequency analysis of the structure noise signals could reflect the failure state of CRDM and could discriminate the failure types of CRDM effectively. |
