Abstract
Decay ratio was estimated via a simplified method from the impulse res ponse function that had been evaluated using a univariable auto regres sion method. Suggested estimation was utilized in neutron noise measur ements carried out during seven fuel cycles of a 1300-MW(electric) pre ssurized water reactor. Results show that such an evaluation method ca n be used to monitor the increasing oscillation of the neutron flux du ring the fuel cycle.
