Abstract
An optical fiber-based gamma thermometer (OFBGT) was tested in the water irradiation facility (WIF) of the Ohio State University Research Reactor (OSURR). A distributed measurement of the temperature difference (∆T) between the thermal mass and outer sheath of the OFBGT was acquired using a LUNA Innovations Optical Backscatter Reflectometer (OBR) 4600. The ∆T measurements were converted into linear power density measurements (q′) based on calibration of the OFBGT. The shape and maximum measured q′ in the WIF agree reasonably well with MCNP calculations. The q′ measurements may ultimately be used for axial power inferencing in the OSURR.
