Abstract
This paper presents a data base, SINBAD, constituted of spectral signatures elaborated from ex-core neutron noise and vessel accelerometer signals, which have been recorded on all French PWRs since their start-up. The data base contains 4 100 signatures (PSDs, coherences, phases) and associated unit parameters, issued from 1400 data sets collected over 320 fuel cycles on 54 reactors. This structured data base will make it easier to study the internals mechanical behaviour of the reactor internals in time (aging effects, trends, anomalies...). The paper describes the SINBAD structure and content: it also presents the first results obtained from data processing performed on 28 reactors with a sectorized thermal shield and deals with the evolution of neutron noise fluctuation within several frequency bands versus burn-up.
