Decay ratio was estimated via a simplified method from the impulse response function that had been evaluated using an unvariable autoregression method. Suggested estimation was utilized in neutron noise measurements carried out during seven fuel cycles of a 1,300-MW (electric) pressurized water reactor. Results show that such an evaluation method can be used to monitor the increasing oscillation of the neutron flux during the fuel cycle.
