Section: claims

1. A device configured for reconstructing axial measurement values in a nuclear fuel, the device calculating an axial measurement distribution by reconstructing a plurality of measurement values measured by a plurality of detectors that are disposed at predetermined intervals in the nuclear fuel along the axial direction of the nuclear fuel, the device comprising:a processor that includesa reconstruction parameter generator configured to generate a reconstruction parameter on the basis of core design data, or core analysis data, and a data adjustment factor; andan axial measurement distribution generator configured to calculate an axial measurement distribution in the nuclear fuel on the basis of the measurement values that are measured by the detectors and the reconstruction parameter that is generated by the reconstruction parameter generator,wherein the data adjustment factors are an inclination adjustment factor, an axial distribution adjustment factor, and an integral value adjustment factor. 2. The device for reconstructing axial measurement values in a nuclear fuel according to claim 1, whereinthe axial measurement distribution generator calculates the axial measurement distribution in the nuclear fuel by correcting the reconstruction parameter in accordance with the measurement values such that the deviation between the measurement values and the reconstruction parameter is at minimum. 3. The device for reconstructing axial measurement values in a nuclear fuel according to claim 1 whereinthe axial distribution adjustment factor is comprised of a plurality of adjustment factors for making adjustment with different periods. 4. A method of reconstructing axial measurement values in a nuclear fuel, the method being a method of calculating an axial measurement distribution by reconstructing a plurality of measurement values measured by a plurality of detectors that are disposed at predetermined intervals in the nuclear fuel along the axial direction of the nuclear fuel, the method comprising:a step of generating a reconstruction parameter on the basis of core design data, or core analysis data, and data adjustment factors; anda step of calculating an axial measurement distribution in the nuclear fuel on the basis of the measurement values that are measured by the detectors and the generated reconstruction parameter,wherein the reconstruction parameter is generated on the basis of an inclination adjustment factor, an axial distribution adjustment factor, and an integral value adjustment factor that serve as the data adjustment factors.
