Sensitivity depletion of two rhodium (Rh) self-powered neutron detectors (SPNDs) has been measured since July 1976 at the Oconee 2 pressurized water reactor (PWR). The detectors were positioned inside the reactor core throughout the measurement period. Depletion has been determined as a function of electric charge released by each detector. The goal of the project is the empirical definition of the depletion characteristics over the operating life-time of the Rh detector. Results to date show that the sensitivity depletion rate of the Rh detector in the PWR is highly linear with charge released from the detector.
