Abstract: A dryness fraction distribution measuring device, includes: a light-emitting body that illuminates a gas/liquid two-phase flow with light; an environment sensor that measures at least one of temperature or pressure in a gas/liquid two-phase flow; a plurality of photodetecting elements that receive respective lights that have traversed moist steam; a relationship storing portion that stores, for each temperature or pressure, a relationship between an intensity of light that has traversed the gas/liquid two-phase flow and a dryness fraction of the gas/liquid two-phase flow; and a dryness fraction identifying portion that identifies a dryness fraction of the gas/liquid two-phase flow for each position corresponding to the plurality of photodetecting elements, based on the relationships between the measured values for the detected light intensities of the lights detected by the respective photodetecting elements and the values for the temperatures and pressures measured by the environment sensor.
