| 摘要 |
The invention relates to a method for obtaining (206) an error propagation uncertainty component (R) for any nuclear reactor including reactors intended to be provided with a measurement instrumentation system for which there is no operation feedback concerning the system in question. For this purpose, the invention comprises the use of data (200) originating from experience feedback acquired with a reference instrumentation system, e.g. the core instrumentation reactor system. The experience feedback is used to apply disturbances to a theoretical power distribution model (201), the spatial distribution and amplitude of said disturbances being such that the deviations observed (203) between the disturbed theoretical model and the theoretical model resulting directly from the calculation are representative of those observed in reality.
