Behavior of neutron noise during the first and second fuel cycles of Sequoyah-1 PWR

OSTI ID:6265037
Ex-core neutron detector noise has been utilized extensively to monitor core support barrel (CSB) vibrations. Previous studies have found that only moderate increases in neutron noise normally occur over a fuel cycle in the frequency ranges associated with CBS motion. In order to observe long-term changes in the neutron noise under varying conditions, noise signals at Sequoyah-1, a Westinghouse 1150-MW(e) pressurized water reactor (PWR), were monitored continuously during the entire first fuel cycle and approximately three months of the second fuel cycle.
