摘要：

Decay ratio was estimated via a simplified method from the impulse response function that had been evaluated using a univariable auto regression method. Suggested estimation was utilized in neutron noise measurements carried out during seven fuel cycles of a 1300-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.
