[en] The vibratory measurements which are available on the reactor have simultaneously been recorded with the fluctuations of neutronic power measurements. The observations correspond to: a movement of the carrier concrete slab of the primary circuit at the fundamental frequency corresponding to the pumps rotary speed, a low level vibration on a control rod drive corresponding to an incipient defect, vibrations emergence on the core cover during a working cycle, and all the time, a resonance corresponding to the first vibrational mode of the fuel assemblies under the cooling sodium flow. The evidence of the vibratory movement has been obtained by the systematic calculation of the coherence function between the available neutronic noise measurements and the vibratory transducers. From the experience gained on PHENIX, vibration measurements are included in the SUPER PHENIX monitoring system
