INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a technique for estimating a state in a nuclear reactor from information associated with Cherenkov light obtained by observing the inside of the nuclear reactor.SOLUTION: An information processing device as an aspect of the present invention includes an image acquisition part which acquires an image of Cherenkov light imaged by an imaging device observing the inside of a nuclear reactor, and a state estimation part which converts a shading value of each area of the acquired image into a photon number of the Cherenkov light generated in the area using photon generation number conversion data for converting a shading value of the image into a photon number, and estimates the state in the nuclear reactor based upon photon numbers of the Cherenkov light in the respective areas obtained through the conversion.
