Plant operating state prediction method and nuclear plant operating state prediction system

摘要

PPROBLEM TO BE SOLVED: To predict future performance of a nuclear power plant by using the correlation expression between an operating condition and the data on an operating state acquired, on the basis of the information obtained from a database constructed by storing the data on operating conditions and those on the operating states in the nuclear power plant. PSOLUTION: A system 11 for predicting the operating state of the nuclear power plant 1 is equipped with a section 12 for obtaining data on the operating conditions of the plant 1 from its, a section 13 for obtaining the data on the performance of steam generation that obtains the coefficients of it from a steam generator 3, a data storage section 18 that stores the obtained data on the operating conditions and the coefficients obtained from the performance of steam generation, together with the data on their obtained times respectively, a section 19 for acquiring the correlation between the operating conditions of the nuclear power plant 1 and the coefficient of the performance of steam generation, on the basis of each of the data stored in the data storage section 18 and a section 20 for predicting the performance of the steam generation from the steam generator 3, on the basis of the obtained correlation.
